Description
Technical Field
[0001] The present invention relates to the field of ecological technology, and in particular to a method, device and medium for determining the ecological impact contribution rate based on a traffic corridor. Background Art
[0002] The ecosystem is the material basis for the survival and development of human society. It has important ecological service functions such as supply, regulation, and support, and plays an irreplaceable role in maintaining the ecological balance of the earth.
[0003] As a long-span linear structure, transportation corridors are often surrounded by unique ecosystem characteristics such as heterogeneity in temporal and spatial distribution, combination of points, lines and surfaces, and complex and diverse influencing ecological factors.
[0004] At present, with the rapid development of transportation infrastructure construction, the impact of transportation corridors on the ecological environment is becoming increasingly significant. In order to scientifically evaluate the contribution of transportation corridors to the ecological environment, an effective method is needed to determine the impact of transportation corridors on the changes in ecological environment indicators.
[0005] The existing methods for determining contribution rates are mostly general determinations of human and climate factors, with only qualitative analysis of the impact of land transportation on the ecological environment. There is no quantitative determination of the long-term impact of land transportation on the ecological environment. Summary of the invention
[0006] The technical problem to be solved by the present invention is to achieve quantitative analysis of the long-term impact of land transportation on the ecological environment.
[0007] The technical solution of the present invention to solve the above technical problems is as follows:
[0008] In the first aspect, the present application provides a method for determining the ecological impact contribution rate based on a transportation corridor, using the following technical solutions:
[0009] A method for determining the impact contribution rate based on transportation corridors includes:
[0010] Obtain the geographic information of the target transportation corridor and the assessment time period information;
[0011] Dividing the target traffic corridor into a plurality of target road sections based on the geographic information, and obtaining construction time information corresponding to each of the target road sections;
[0012] For each of the target road sections, determining an ecological reference system of the target road section based on the construction time information of the target road section, wherein the ecological reference system is any one of a historical ecological reference system and a natural ecological reference system;
[0013] Calculate the ecological impact contribution rate of the target road section based on the evaluation time period information, the ecological reference system of the target road section and a preset contribution rate determination calculation rule;
[0014] Based on the ecological impact contribution rates corresponding to the target road sections and the preset traffic corridor contribution rate calculation rules, the ecological impact contribution rate of the target traffic corridor is calculated.
[0015] The beneficial effects of the present invention are as follows: by dividing the target traffic corridor into multiple target sections and calculating the ecological impact contribution rate for each target section, the overall impact of the traffic corridor on the ecological environment can be more comprehensively evaluated, and the ecological factors around the traffic corridor can be quantitatively analyzed to more accurately evaluate the contribution rate of the traffic corridor to the ecological environment, thereby avoiding the subjectivity and uncertainty of qualitative analysis. By introducing the concept of ecological reference system, including historical ecological reference system and natural ecological reference system, the ecological reference system of the target section is determined according to the construction time information of the target section, so that the ecological impact contribution rate of the traffic corridor in different time periods can be more accurately evaluated.
[0016] Based on the above technical solution, the present invention can also be improved as follows.
[0017] Further, the target road section includes an evaluation area and a reference area, and the target road section includes an evaluation area and a reference area, and the ecological reference system of the target road section is determined based on the construction time information of the target road section, including:
[0018] Determine whether the construction time information of the target road section is greater than a preset time;
[0019] If the construction time information of the target road section is greater than the preset time, determining the historical ecological reference system of the evaluation area of the target road section based on the historical condition method, and using the historical ecological reference system as the ecological reference system of the target road section;
[0020] If the construction time information of the target road section is not greater than the preset time, the natural ecological reference system of the evaluation area of the target road section is determined based on the natural condition method, and the natural ecological reference system is used as the ecological reference system of the target road section.
[0021] The beneficial effect of adopting the above further scheme is: since remote sensing satellites started in the late 1990s, ecological data developed based on remote sensing satellite images began to be generated after 1990. Generally, the highways / railways built after 2000 should adopt the historical ecological reference system to determine the contribution rate. Therefore, a preset time is set, and the construction time of the target section is compared with the preset time according to the construction time information of the target section. For sections with a construction time greater than the preset time, it means that the historical data is sufficient, and the selection of the historical ecological reference system can better reflect the impact of the transportation corridor on the ecological environment; for sections with a construction time not greater than the preset time, it means that the historical ecological data is lacking. For target sections lacking historical ecological data, the selection of the natural ecological reference system can better reflect the original ecological conditions. According to the construction time information of the target section, the ecological reference system of the assessment area can be determined more accurately, thereby improving the accuracy of the contribution rate determination.
[0022] By dividing the target road section into an assessment area and a reference area, and using the historical condition method and the natural condition method to determine the ecological reference system for spatial paired comparison of impact assessment, the overall impact of the transportation corridor on the ecological environment can be more comprehensively assessed. The assessment area is used to calculate the ecological impact contribution rate of the target road section, and the reference area is used to compare the ecological conditions of different time periods or different regions.
[0023] Furthermore, the ecological reference system includes a plurality of ecological parameters, and the historical ecological reference system for determining the evaluation area of the target road section based on the historical condition method includes:
[0024] Determining the historical time period of the target road section according to the construction time information of the target road section;
[0025] Acquire first historical ecological parameter information of various ecological parameters of the evaluation area of the target road section, wherein the first historical ecological parameter information is ecological parameter information of a historical time period and ecological parameter information of an evaluation time period, and the ecological parameter is any one of a vegetation coverage parameter, NDVI, soil erosion modulus, a water network density parameter, and a biodiversity index;
[0026] Based on the first historical ecological parameter information corresponding to each ecological parameter and a preset historical ecological reference system algorithm, the historical ecological reference system of the evaluation area of the target road section is calculated.
[0027] The beneficial effect of adopting the above further scheme is that by obtaining the historical ecological parameter information of the target section and calculating based on the preset historical ecological reference system algorithm, the historical ecological reference system of the assessment area can be determined more accurately, thereby improving the accuracy of the contribution rate determination. Taking into account multiple ecological parameters, including vegetation coverage parameters, NDVI, soil erosion modulus, water network density parameters and biodiversity index, the impact of the transportation corridor on the ecological environment can be more comprehensively evaluated. By comparing the ecological parameters of the evaluation period of the section with the ecological parameters of the historical event section, it is more convenient to evaluate the overall impact of the transportation corridor on the ecological environment and identify potential ecological problems.
[0028] Furthermore, the ecological reference system includes a plurality of ecological parameters, and the natural ecological reference system of the evaluation area of the target road section determined based on the natural condition method includes:
[0029] Acquire second historical ecological parameter information of each ecological parameter of the reference area of the target road section, wherein the second historical ecological parameter information is ecological parameter information of an evaluation period; the ecological parameter is any one of a vegetation coverage parameter, NDVI, soil erosion modulus, a water network density parameter, and a biodiversity index;
[0030] Based on the second historical ecological parameter information corresponding to each ecological parameter and a preset natural ecological reference system algorithm, the natural ecological reference system of the evaluation area of the target road section is calculated.
[0031] The beneficial effect of adopting the above further scheme is that since the target road section does not have sufficient historical ecological data, the natural ecological reference system is used to obtain the historical ecological parameter information of the reference area of the target road section and calculate based on the preset natural ecological reference system algorithm, so that the natural ecological reference system of the assessment area can be more accurately determined, thereby being closer to the ecological environment status under the natural state. The natural ecological reference system adopts the principle of replacing time with space. When there is a lack of historical ecological status data, the ecological status of the reference area surrounding the assessment area is used as the ecological status of the assessment area not affected by the road / railway.
[0032] Furthermore, when the ecological reference system of the target road section is a historical ecological reference system, the ecological impact contribution rate of the target road section is calculated based on the evaluation time period information, the ecological reference system of the target road section and a preset contribution rate determination calculation rule, including:
[0033] Obtaining an influencing factor of each ecological parameter in an ecological reference system corresponding to the target road section, wherein the influencing factor is a combination of at least two of precipitation factors, temperature factors, terrain factors, humidity factors, traffic flow and traffic facilities;
[0034] Acquire a plurality of first impact data corresponding to each of the impact factors of the assessment area in the historical time period;
[0035] For each ecological parameter of the historical ecological reference system of the assessment area, a function equation of the ecological parameter and two influencing factors corresponding to the ecological parameter is established according to a plurality of first influencing data corresponding to the ecological parameter, and a linear fitting is performed on the function equation to obtain a first correlation algorithm for the target road section;
[0036] For each of the influencing factors, a plurality of second influencing data of the influencing factor in the evaluation time period is obtained, and a first average influencing data of the influencing factor in the evaluation time period is calculated according to the plurality of second influencing data;
[0037] Input each of the first average impact data into the first correlation algorithm to obtain a first ecological parameter reference value of the evaluation area of the target road section in the evaluation time period;
[0038] Calculate the first average ecological parameter value of each ecological parameter in the historical ecological reference system of the assessment area during the assessment period;
[0039] Based on each of the first average ecological parameter values and each of the first ecological parameter reference values, the ecological impact contribution rate of the target road section is calculated.
[0040] The beneficial effect of adopting the above further scheme is that it takes into account a variety of influencing factors, including precipitation, temperature and traffic, and can more comprehensively evaluate the long-term impact of the transportation corridor on the ecological environment. By establishing a functional equation of ecological parameters and influencing factors and performing linear fitting, the calculation process of determining the contribution rate is more scientific and accurate. By comparing the changes in the ecological environment of the assessment area in the historical time period and the assessment time period, that is, by comparing the changes in the ecological environment during the construction period and the pre-construction period of the assessment area, the contribution rate of the construction activities to the impact of the railway surrounding area can be obtained. It is also possible to compare the changes in the ecological environment during the operation period and the pre-construction period of the assessment area to obtain the contribution rate of the railway to the surrounding area.
[0041] Further, the ecological impact contribution rate of the target road section is calculated based on the evaluation time period information, the ecological reference system of the target road section and a preset contribution rate determination calculation rule, including:
[0042] Obtaining an influencing factor of each ecological parameter in an ecological reference system corresponding to the target road section, wherein the influencing factor is a combination of at least two of precipitation factors, temperature factors, terrain factors, humidity factors, traffic flow and traffic facilities;
[0043] Acquire a plurality of third impact data of each of the impact factors in the reference area in the evaluation time period;
[0044] For each ecological parameter of the natural ecological reference system of the reference area, a function equation of the ecological parameter and the corresponding two influencing factors is established according to a plurality of third influencing data corresponding to the ecological parameter, and a linear fitting is performed on the function equation to obtain a second correlation algorithm for the target road section;
[0045] For each of the influencing factors, a plurality of fourth influencing data of the influencing factor in the evaluation area in the evaluation time period are obtained, and a second average influencing data of the influencing factor in the evaluation time period is calculated according to the plurality of fourth influencing data;
[0046] Input each of the average impact data into the second correlation algorithm to obtain a second ecological parameter reference value of the evaluation area of the target road section during the evaluation time period;
[0047] Calculate a second average ecological parameter value of each ecological parameter in the natural ecological reference system of the assessment area during the assessment time period;
[0048] Based on each of the second average ecological parameter values and the corresponding second ecological parameter reference value, the ecological impact contribution rate of the target road section is calculated.
[0049] The beneficial effects of adopting the above further scheme are: by obtaining the influencing factors of each ecological parameter in the ecological reference system corresponding to the target section, and establishing a function equation based on these influencing factors for linear fitting, the ecological impact contribution rate of the target section can be calculated more accurately; by using the ecological parameters of the reference area of the evaluation time period to replace the ecological parameters of the evaluation area of the historical time period to calculate the contribution rate of the ecological impact of the traffic corridor, the contribution rate of the ecological impact of the traffic corridor is calculated based on the principle of space instead of time, avoiding the lack of data and the inability to conduct quantitative analysis of the ecological impact of the traffic corridor. By comparing the ecological changes in the reference area evaluation time period and the evaluation area evaluation time period, that is, the ecological parameters of the reference area evaluation time period are used to replace the ecological parameters of the historical time period of the evaluation area where the data is missing.
[0050] Furthermore, the obtaining of the influencing factors of each ecological parameter in the ecological reference system corresponding to the target road section includes:
[0051] Acquire the original data sample of the target road section; the original data sample includes relevant ecological parameters, climate factor information and traffic factor information;
[0052] Determine, based on the original data sample and a preset principal component analysis method, a plurality of driving factors corresponding to each ecological parameter of the ecological reference system of the target road section, wherein the driving factors are factors that affect changes in ecological parameters;
[0053] For each ecological parameter, determining the correlation between the ecological parameter and each corresponding driving factor according to a preset correlation method;
[0054] According to the relevance of each of the driving factors, the influencing factors corresponding to the ecological parameters are determined.
[0055] The beneficial effect of adopting the above further scheme is that through the original data sample of the target traffic corridor and the preset principal component analysis method, multiple driving factors corresponding to each ecological parameter in the ecological reference system are determined, and the correlation between the ecological parameter and each driving factor is further determined according to the correlation method. Comprehensively considering various influencing factors avoids the possibility of missing important factors and improves the accuracy of determining the ecological influencing factors of the target traffic corridor.
[0056] Furthermore, the geographic information of the target traffic corridor includes length information, and the calculation of the ecological impact contribution rate of the target traffic corridor based on the contribution rate corresponding to each target road section and a preset traffic corridor contribution rate calculation rule includes:
[0057] Obtaining distance information corresponding to each target road section, wherein the distance information is the distance between the starting point and the end point of the target road section;
[0058] Calculating the distance ratio of each target road section in the target traffic corridor according to the distance information of each target road section and the length information of the target traffic corridor;
[0059] Based on the distance ratio of each target road section, the contribution rate corresponding to each target road section is weighted averaged to obtain the ecological impact contribution rate of the target traffic corridor.
[0060] The beneficial effect of adopting the above further scheme is that by obtaining the distance information corresponding to each target section and calculating the distance ratio of each target section in the target traffic corridor based on the distance information, the relative contribution of each target section can be determined more accurately. On this basis, by weighted averaging the contribution rate of each target section, the overall ecological impact contribution rate of the target traffic corridor can be obtained, so that the overall ecological impact contribution rate of the target traffic corridor can be calculated more accurately.
[0061] In a second aspect, the present application provides an electronic device, which adopts the following technical solution:
[0062] An electronic device comprises a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and executes the method for determining the ecological contribution rate based on a transportation corridor as described in any one of the first aspects.
[0063] The beneficial effects of the present invention are as follows: the processor executes the method for determining the ecological impact contribution rate based on the traffic corridor stored in the memory, by dividing the target traffic corridor into multiple target sections and calculating the ecological impact contribution rate for each target section, so as to more comprehensively evaluate the overall impact of the traffic corridor on the ecological environment, and quantitatively analyze the ecological factors around the traffic corridor, so as to more accurately evaluate the contribution rate of the traffic corridor to the ecological environment, and avoid the subjectivity and uncertainty of qualitative analysis. By introducing the concept of ecological reference system, including historical ecological reference system and natural ecological reference system, the ecological reference system of the target section is determined according to the construction time information of the target section, so as to more accurately evaluate the ecological impact contribution rate of the traffic corridor in different time periods.
[0064] In a third aspect, the present application provides a computer-readable storage medium, which adopts the following technical solution:
[0065] A computer-readable storage medium stores a computer program that can be loaded by a processor and execute the method for determining the ecological impact contribution rate based on a transportation corridor as described in any one of the first aspects.

In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.
[0074] An embodiment of the present application provides a method for determining the ecological impact contribution rate based on a traffic corridor. The method for determining the ecological impact contribution rate based on a traffic corridor can be executed by an electronic device, which can be a server or a mobile terminal device, wherein the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services; the mobile terminal device can be a laptop computer, a desktop computer, etc., but is not limited to this.
[0075] The following is a further detailed description of the embodiments of the present application in conjunction with the accompanying drawings. Figure 1 As shown, a method for determining the ecological impact contribution rate based on a traffic corridor includes steps S1 to S5:
[0076] Step S1, obtaining geographic information and evaluation time period information of the target transportation corridor;
[0077] In one implementation, a transportation corridor is a strip-shaped space composed of several parallel transportation routes with roughly the same starting and ending points, usually composed of two or more highways of different grades or highways and railways, with large traffic and high service level requirements. It is a strip-shaped spatial regional economic complex formed by the aggregation of industries, population, resources, information, towns, passenger and freight flows, etc., with a high-efficiency integrated transportation channel as the main development axis, relying on large and medium-sized towns on the axis or in the area closely attracted by it.
[0078] like Figure 2 As shown, at present, based on the scope and degree of direct impact of roads and railways on the ecology, transportation corridors are divided into assessment areas and reference areas. In the implementation mode of this application, the area of 1 km around the road or railway is used as the assessment area, and the area extending 2 km on both sides of the assessment area is used as the reference area.
[0079] The geographic information of the target transportation corridor is collected by satellite remote sensing, including but not limited to the starting point, end point, length, width, topography and vegetation coverage of the transportation corridor. The electronic equipment pre-processes the collected data, including data cleaning, format conversion, outlier processing, etc., to ensure the accuracy and reliability of the data. After that, the geographic information is converted into a computer-readable form, usually encoded and stored using a geographic information system (GIS).
[0080] The evaluation time period can be selected according to the research purpose and actual needs, and can be input into the electronic device by the user. The electronic device responds to the instructions input by the user to obtain the evaluation time period of the target traffic corridor. The evaluation time period can be a season, the construction period of the target traffic corridor, and the operation period of the target traffic corridor, etc.
[0081] Step S2, dividing the target traffic corridor into a plurality of target sections based on the geographic information, and obtaining construction time information corresponding to each target section;
[0082] In one implementation, the electronic device first performs feature analysis on the collected geographic information through the GIS software, and uses whether the evaluation areas and reference areas of multiple traffic routes of the traffic corridor overlap as the division condition of the target traffic corridor, and uses the editing function of the GIS software to divide the traffic corridor into multiple target sections. Each target section should have a certain degree of coherence and consistency.
[0083] Afterwards, for each divided target road section, further query or collect relevant construction time information, which may come from road construction records, historical archives or other relevant materials.
[0084] The divided target road sections and the corresponding construction time information are organized into tables or databases to facilitate subsequent data processing and ecological impact assessment.
[0085] After dividing the target traffic corridor into multiple target sections, the evaluation and reference areas of each target section are redefined as follows:
[0086] For each adjacent target road section, the electronic device determines whether there is an overlapping area between two adjacent target road sections, and if there is an overlapping area, determines whether the spatial overlap area between the evaluation area and the reference area of the two target road sections exceeds a preset threshold;
[0087] If the spatial overlap area of the evaluation area and the reference area of the two target sections exceeds a preset threshold, the two target sections are both regarded as comprehensive impact target sections, and the two comprehensive impact target sections are merged into one target section;
[0088] If the spatial overlap area of the evaluation area and the reference area of the two target sections does not exceed a preset threshold, the two target sections are regarded as a single impact target section.
[0089] For each single impact target road section, the evaluation area and the reference area of the single impact target road section are determined according to the first division method. In the implementation mode of the present application, the area of 1 km around the single impact target road section is used as the evaluation area, and the area extending 2 km outward on both sides of the evaluation area is used as the reference area;
[0090] For each comprehensive impact target road section, the evaluation area and reference area of the comprehensive impact target road section are determined according to the second division method. In the implementation mode of the present application, the outermost 2-kilometer area of the two comprehensive impact target road sections is the reference area, and the overlapping part in the middle is the evaluation area.
[0091] The following example takes the assessment area and reference area of two highways or railways in the target transportation corridor as an example.
[0092] When the spatial overlap area between the assessment area and the reference area of two highways or railways in a land transportation corridor exceeds 10%, the target section is considered to be a comprehensive impact target section; when the spatial overlap area between the assessment area and the reference area of two highways or railways does not exceed 10%, the target section is considered to be a single impact target section.
[0093] It should be noted that, for every two adjacent comprehensive impact target sections, the two comprehensive impact target sections are merged into one target section to calculate the ecological impact contribution rate; for a single impact target section, the ecological impact contribution rate of each target section is calculated.
[0094] For example, the target traffic corridor includes two roads, each of which is 100 kilometers long, and there is a 10-kilometer reference area that overlaps. In this case, the two sections corresponding to the overlapping 10 kilometers are respectively regarded as two comprehensive impact target sections, and the non-overlapping road is regarded as a single impact target section. When calculating the ecological impact contribution rate of the target traffic corridor, the two comprehensive impact target sections are regarded as one target section and the ecological impact contribution rate corresponding to one target section is calculated. The corresponding ecological contribution rates of the single impact target sections contained in the remaining 180 kilometers are calculated separately.
[0095] Step S3, for each target road section, determining an ecological reference system of the target road section based on the construction time information of the target road section, wherein the ecological reference system is any one of a historical ecological reference system and a natural ecological reference system;
[0096] In one embodiment, the ecological reference system refers to a standard or state used for reference and comparison in the process of ecological restoration. The ecological reference system includes multiple ecological parameters, and the ecological parameter is any one of a vegetation cover parameter, NDVI, soil erosion modulus, a water network density parameter, and a biodiversity index.
[0097] Specifically, Figure 3 As shown, the electronic device determines whether the construction time information of the target road section is greater than a preset time;
[0098] If the construction time information of the target road section is greater than the preset time, the historical ecological reference system of the evaluation area of the target road section is determined based on the historical condition method, and the historical ecological reference system is used as the ecological reference system of the target road section; if the construction time information of the target road section is not greater than the preset time, the natural ecological reference system of the evaluation area of the target road section is determined based on the natural condition method, and the natural ecological reference system is used as the ecological reference system of the target road section.
[0099] It should be noted that due to the development of satellite remote sensing, ecological data only began to be generated after 1990. Therefore, there is a lack of ecological data for roads or railways built before 1990. In the implementation mode of the present application, the preset time is set to 2000. For sections built after 2000, there is sufficient historical ecological data, and the historical condition method is used to determine the historical ecological reference system of the assessment area of the target section; for sections built before 2000, there is a lack of sufficient historical ecological data, and the natural condition method is used to determine the natural ecological reference system of the assessment area of the target section. By using the construction time information of the target section, the ecological reference system of the assessment area can be determined more accurately, thereby improving the accuracy of the contribution rate determination.
[0100] Wherein, the historical ecological reference system of the evaluation area of the target road section determined based on the historical condition method includes steps S311 to S313:
[0101] Step S311, determining the historical time period of the target road section according to the construction time information of the target road section;
[0102] In one embodiment, the construction time of each road section is obtained based on the existing traffic corridor construction data, that is, the time point when each target road section starts construction or is completed. According to the construction time information, the historical time period of each target road section is determined. For example, if the construction time of a target road section starts in 2000, then its historical time period is from 2000 to the time point of the evaluation of the target road section.
[0103] Step S312, obtaining first historical ecological parameter information of various ecological parameters of the evaluation area of the target road section, wherein the first historical ecological parameter information is ecological parameter information of a historical time period and ecological parameter information of an evaluation time period, and the ecological parameter is any one of a vegetation coverage parameter, NDVI, soil erosion modulus, a water network density parameter, and a biodiversity index;
[0104] In one implementation, based on the historical time period of the target road section, ecological parameter information within the time period is obtained through historical data archives, research reports, and the like.
[0105] Step S313, based on the first historical ecological parameter information corresponding to each ecological parameter and the preset historical ecological reference system algorithm, calculate the historical ecological reference system of the evaluation area of the target road section
[0106] The preset historical ecological reference system algorithm is:
[0107] ELS 评估区 =Eco mean评估区 ;
[0108] Among them, ELS 评估区 is any ecological parameter in the historical ecological reference system of the assessment area of the target road section, Eco mean评估区 It is the average data of each first historical ecological parameter information corresponding to any ecological parameter.
[0109] Based on the preset historical ecological reference system algorithm, various ecological parameters in the historical ecological reference system can be calculated, and based on the determined ecological parameters, the historical ecological reference system can be determined.
[0110] In one embodiment, an ecological parameter of the historical ecological reference system of the assessment area of the target road section is equal to the average ecological parameter of the assessment area in the historical time period and the assessment time period. Each ecological parameter of the target road section is calculated to obtain the historical ecological reference system of the assessment area of the target road section.
[0111] By obtaining the historical ecological parameter information of the target road section and calculating it based on the preset historical ecological reference system algorithm, the historical ecological reference system of the assessment area can be determined more accurately, thereby improving the accuracy of the contribution rate determination. Taking into account multiple ecological parameters, including vegetation coverage parameters, NDVI, soil erosion modulus, water network density parameters and biodiversity index, the impact of transportation corridors on the ecological environment can be more comprehensively evaluated.
[0112] The natural ecological reference system of the evaluation area of the target road section determined based on the natural condition method includes steps S321 to S323:
[0113] Step S321, obtaining second historical ecological parameter information of each ecological parameter of the reference area of the target road section, wherein the second historical ecological parameter information is ecological parameter information of an evaluation time period;
[0114] In one embodiment, for roads or railways built before 2000, there is no historical ecological parameter information corresponding to the assessment area in the historical time period, so the historical ecological parameter information of the reference area of the target section is obtained. For example, for a road built in 1990, the assessment time period is 1990-2020, and there is no historical ecological parameter information of the assessment area before 2000, so the average ecological parameter data of the reference area from 2000 to 2020 is obtained instead of the ecological parameter information corresponding to the assessment area in the historical time period.
[0115] Step S322, calculating the natural ecological reference system of the evaluation area of the target road section based on the second historical ecological parameter information corresponding to each ecological parameter and a preset natural ecological reference system algorithm;
[0116] Among them, the preset natural ecological reference system algorithm is:
[0117] EZR 评估区 =Eco mean参照区 ;
[0118] Among them, EZR 评估区 is any ecological parameter in the natural ecological reference system of the evaluation area of the target road section, Eco mean参照区 It is the average data of each second historical ecological parameter information corresponding to any ecological parameter.
[0119] Based on the preset natural ecological reference system algorithm, various ecological parameters in the natural ecological reference system can be calculated, and based on the determined ecological parameters, the natural ecological reference system can be determined.
[0120] When there is insufficient historical ecological data for the target section, the natural ecological reference system can be used to obtain historical ecological parameter information of the reference area of the target section and calculate based on the preset natural ecological reference system algorithm to more accurately determine the natural ecological reference system of the assessment area, so as to be closer to the ecological environment in the natural state. The natural ecological reference system adopts the principle of replacing time with space. When there is a lack of historical ecological status data, the ecological status of the reference area surrounding the assessment area is used as the ecological status of the assessment area not affected by the road / railway.
[0121] Step S4, calculating the ecological impact contribution rate of the target road section based on the evaluation time period information, the ecological reference system of the target road section and a preset contribution rate determination calculation rule;
[0122] In one implementation, specifically, when the ecological reference system of the target road section is a historical ecological reference system, step S4 includes the following sub-steps:
[0123] Step S411, obtaining the influencing factors of each ecological parameter in the ecological reference system corresponding to the target road section, wherein the influencing factors are a combination of at least two of precipitation factors, temperature factors, terrain factors, humidity factors, traffic flow and traffic facilities;
[0124] Step S412, obtaining a plurality of first impact data corresponding to each of the impact factors of the assessment area in the historical time period;
[0125] In one embodiment, the influencing factors may also be any three or more combinations of precipitation factors, temperature factors, terrain factors, humidity factors, traffic flow and traffic facilities, etc., but are not limited thereto.
[0126] Step S413, for each ecological parameter of the historical ecological reference system of the assessment area, a function equation of the ecological parameter and the two influencing factors corresponding to the ecological parameter is established according to multiple first influencing data corresponding to the ecological parameter, and the function equation is linearly fitted to obtain the first relevant algorithm of the target section; for example, temperature and precipitation are determined as influencing factors, then a linear relationship model between the ecological parameter and these two factors can be established.
[0127] In one embodiment, the first correlation algorithm is:
[0128] ELS 评估区 =A*temp 历史 +B*prep 历史 +C
[0129] Among them, ELS 评估区 is the reference value of an ecological parameter in the historical period of the assessment area, temp 历史 is the first average impact data of multiple first impact factors corresponding to the assessment area in the historical time period, prep 历史 It is the first average impact data of multiple second impact factors corresponding to the assessment area in the historical time period, and A, B, and C are all fitting coefficients.
[0130] In other embodiments, if there are three influencing factors, a function equation is established between each ecological parameter and the corresponding three influencing factors; if there are four influencing factors, a function equation is established between each ecological parameter and the corresponding four influencing factors, and so on. In the embodiment of the present application, the influencing factors are preferably set to two.
[0131] Step S414: for each of the influencing factors, obtain a plurality of second influencing data of the influencing factor in the evaluation time period, and calculate a first average influencing data of the influencing factor in the evaluation time period according to the plurality of second influencing data;
[0132] Step S415, inputting each of the first average impact data into the first correlation algorithm to obtain a first ecological parameter reference value of the evaluation area of the target road section in the evaluation time period;
[0133] Step S416, calculating a first average ecological parameter value of each ecological parameter in the historical ecological reference system of the assessment area during the assessment time period;
[0134] Step S417, based on each of the first average ecological parameter values and each of the first ecological parameter reference values, calculate the ecological impact contribution rate of the target road section, where the ecological impact contribution rate is a percentage corresponding to the ratio between the first ecological reference value and the first average ecological parameter value.
[0135] In one embodiment, Figure 2 and Figure 3 As shown, the input parameters can be the ecological parameters of the assessment area during the assessment time period, the climate factor information or the traffic factor information is input according to the type of influencing factors, and the time period sets the assessment time period and the historical time period. The above method can output the ecological reference system of the target section and calculate the ecological impact contribution rate based on the ecological reference system.
[0136] When it is necessary to calculate the ecological impact contribution rate of the target road section during the construction period, Figure 2 If the construction period contribution rate is marked in the figure, then the time period to be entered for the evaluation period is the construction period, and the construction period is used as the evaluation period. When the ecological impact contribution rate of the target road section during the operation period needs to be calculated, Figure 2 If it is marked as the contribution rate of the operation period, then the time period entered for the evaluation period is the time period of the operation period, and the time period of the operation period is used as the evaluation period.
[0137] By comprehensively considering a variety of influencing factors, including precipitation, temperature and traffic, the long-term impact of transportation corridors on the ecological environment can be more comprehensively evaluated. By establishing functional equations of ecological parameters and influencing factors and performing linear fitting, the calculation process of determining the contribution rate is made more scientific and accurate. By comparing the changes in the ecological environment of the assessment area in the historical time period and the assessment time period, that is, by comparing the changes in the ecological environment during the construction period and the pre-construction period of the assessment area, the contribution rate of the construction activities during the construction period to the surrounding areas of the railway or highway can be obtained. The ecological environment changes during the operation period and the pre-construction period of the assessment area can also be compared to obtain the contribution rate of the railway or highway during the operation period to the surrounding ecology.
[0138] When the ecological reference system of the target road section is a natural ecological reference system, step S4 includes the following sub-steps:
[0139] Step S421, obtaining the influencing factors of each ecological parameter in the ecological reference system corresponding to the target road section, wherein the influencing factors are any two combinations of precipitation factors, temperature factors, terrain factors, humidity factors, traffic flow and traffic facilities;
[0140] Step S422, obtaining a plurality of third impact data of each of the impact factors in the reference area in the evaluation time period;
[0141] Step S423, for each ecological parameter of the natural ecological reference system of the reference area, a function equation of the ecological parameter and the corresponding two influencing factors is established according to a plurality of third influencing data corresponding to the ecological parameter, and a linear fitting is performed on the function equation to obtain a second correlation algorithm of the target road section;
[0142] In one embodiment, the second correlation algorithm is:
[0143] EZR 参照区 =A*temp 评估时段 +B*prep 评估时段 +C;
[0144] Among them, EZR 参照区 is the reference value of an ecological parameter in the reference area during the assessment period, temp 评估时段 is the second average impact data of multiple first impact factors corresponding to the reference area in the evaluation period, prep 评估时段 is the second average impact data of multiple second impact factors corresponding to the reference area in the evaluation period, and A, B, and C are all fitting coefficients.
[0145] It should be noted that the method of selecting influencing factors and establishing functional equations of ecological parameters and corresponding influencing factors in step S423 and step S413 is the same, and will not be explained here.
[0146] Step S424, for each of the influencing factors, obtaining a plurality of fourth influencing data of the influencing factor in the evaluation area in the evaluation time period, and calculating a second average influencing data of the influencing factor in the evaluation time period according to the plurality of fourth influencing data;
[0147] Step S425, inputting each of the average impact data into the second correlation algorithm to obtain a second ecological parameter reference value of the evaluation area of the target road section in the evaluation time period;
[0148] Step S426, calculating a second average ecological parameter value of each ecological parameter in the natural ecological reference system of the assessment area during the assessment time period;
[0149] Step S427, based on each of the second average ecological parameter values and the corresponding second ecological parameter reference value, calculate the ecological impact contribution rate of the target road section, and the ecological impact contribution rate is the percentage corresponding to the ratio between the second ecological parameter reference value and the second average ecological parameter value.
[0150] The contribution rate of the transport corridor to the ecological impact is calculated by using the ecological parameters of the reference area in the assessment period to replace the ecological parameters of the assessment area in the historical period. The contribution rate of the transport corridor to the ecological impact is calculated based on the principle of space replacing time, so as to avoid the inability to conduct quantitative analysis of the impact of the transport corridor on the ecology due to missing data. By comparing the ecological changes in the reference area assessment period and the assessment area assessment period, that is, the ecological parameters of the reference area assessment period are used to replace the ecological parameters of the historical period of the assessment area where data is missing.
[0151] As an implementation method for obtaining the influencing factors of each ecological parameter in the ecological reference system corresponding to the target road section, the steps Sa to Sd are included:
[0152] Step Sa, obtaining the original data sample of the target road section; the original data sample includes relevant ecological parameters, climate factor information and traffic factor information;
[0153] Step Sb, determining multiple driving factors corresponding to each ecological parameter of the ecological reference system of the target road section according to the original data sample and a preset principal component analysis method, wherein the driving factors are factors that affect changes in ecological parameters;
[0154] In one implementation, first, the following matrix is established using the original data samples:
[0155] X=(X ij )n×p, i=1, 2,…,n; j=1, 2,…,p;
[0156] Among them, n is the number of samples, and p is the number of indicators for each sample.
[0157] Secondly, the original data samples are standardized to eliminate the influence of different orders of magnitude and dimensions among the original data. The sample data after standardization is as follows:
[0158]
[0159] Among them, Z ij is the standardized value of the jth indicator at the ith station, X ij is the measured value of the jth indicator at the ith station, The mean of the jth indicator; σ j is the standard value of the jth indicator.
[0160] After that, the standardized data were subjected to KMO (Kaiser Meyer-Olkin-Measure of Sampling Adequacy) test and Bartlett Test of Sphercity. The KMO test is to test the relative size of the simple correlation coefficient and partial correlation coefficient between the original variables. The closer the KMO value is to 1, the stronger the correlation between the variables is, and the more suitable the original variables are for factor analysis. The Bartlett sphericity test verifies the correlation between the variables by judging whether the correlation matrix is a unit matrix. If the correlation matrix is a unit matrix, the variables are independent of each other and are not suitable for factor analysis. Otherwise, they are suitable for factor analysis. When the KMO test value is greater than 0.5 and the Bartlett sphericity test value is less than 0.001, it indicates that the variables in the data are related to each other and are not independent, and principal component analysis can be performed.
[0161] Afterwards, the correlation coefficient matrix of the variables is established based on the standardized data matrix: R = (r ij )p×p, according to the characteristic equation |R-λ i |=0, calculate the eigenvalue λ of R i (i=1,2,…,p), which is the variance of the principal component, and the eigenvalues are arranged from large to small as λ1≥λ2≥…≥λ p , then the variance contribution rate is The cumulative variance contribution rate is
[0162] The eigenvectors corresponding to different eigenvalues are I g =(I g1 , I g2 ,…,I gp )T, (g = 1, 2, ..., p), the standardized data is converted into principal components F through eigenvectors. The number of principal components m is determined according to the principle that the cumulative contribution rate of the principal component variance is at least 80% or the eigenvalue is greater than 1.0.
[0163] Finally, calculate the comprehensive score of the principal components. First, find the values of the first m principal components of each station i, that is:
[0164] F ij =Z i1 I g1 +Z i2 I g2 +…+Z ip I gp ;i=1,2,…,n;g=1,2,…,m.
[0165] The weighted sum of the first m principal components is performed, and the weight coefficient of each principal component is the variance contribution rate of the principal component, and finally multiple driving factors of ecological environment changes in land transportation corridors are obtained. The comprehensive score calculation formula for each station of this driving factor is as follows:
[0166]
[0167] Step Sc, for each ecological parameter, determining the correlation between the ecological parameter and each corresponding driving factor according to a preset correlation method;
[0168] In one embodiment, the correlation method is used to determine the correlation between the main influencing factors in step Sb and a certain ecological environment indicator. Regression analysis is used for calculation, and the main equation is as follows:
[0169] Y=(X1Y1+X2Y2+...X n Y n-nXY ) / (X1+X2+...X n-nX ).
[0170] Step Sd: determining the influencing factors corresponding to the ecological parameters according to the correlation of each of the driving factors.
[0171] In one embodiment, if two influencing factors need to be determined, the two driving factors with the greatest correlation are selected as influencing factors according to the size of the correlation result of each driving factor; if three influencing factors need to be determined, the three driving factors with the greatest correlation are selected as influencing factors according to the size of the correlation result of each driving factor.
[0172] Through the original data samples of the target transportation corridor and the preset principal component analysis method, multiple driving factors corresponding to each ecological parameter in the ecological reference system were determined, and the correlation between the ecological parameter and each driving factor was further determined based on the correlation method. Comprehensively considering various influencing factors avoids the possibility of missing important factors and improves the accuracy of determining the ecological influencing factors of the target transportation corridor.
[0173] In addition, the main factors affecting the ecological changes in the transportation corridors were determined by analyzing various original data samples through significance tests such as Spearman's test. That is, before the construction of railways or highways, the ecological changes in the assessment area and the reference area are usually mainly affected by temperature and precipitation; during the construction period of railways or highways, the ecological changes in the assessment area are usually mainly affected by temperature, precipitation and multiple effects of construction activities, and the ecological changes in the reference area are usually mainly affected by temperature and precipitation; during the operation period of railways or highways, the ecological changes in the assessment area are usually mainly affected by temperature, precipitation and multiple effects of railways or highways, while the ecological changes in the reference area are usually mainly affected by temperature and precipitation.
[0174] Step S5, calculating the ecological impact contribution rate of the target traffic corridor based on the ecological impact contribution rate corresponding to each of the target road sections and a preset traffic corridor contribution rate calculation rule.
[0175] In one embodiment, first, the distance information corresponding to each of the target sections is obtained, and the distance information is the distance between the starting point and the end point of the target section. The distance information can be obtained from the geographic information system (GIS) software; then, according to the distance information of each of the target sections and the length information of the target traffic corridor, the distance ratio of each of the target sections in the target traffic corridor is calculated. For example, if the length of a target section is 10 kilometers and the length of the entire traffic corridor is 100 kilometers, then the distance ratio of the target section is 10%; finally, based on the distance ratio of each of the target sections, the contribution rate corresponding to each of the target sections is weighted averaged to obtain the ecological impact contribution rate of the target traffic corridor.
[0176] By obtaining the distance information corresponding to each target section and calculating the distance ratio of each target section in the target traffic corridor based on this distance information, the relative contribution of each target section can be determined more accurately. On this basis, by weighted averaging the contribution rate of each target section, the overall ecological impact contribution rate of the target traffic corridor can be obtained, making the calculation of the overall ecological impact contribution rate of the target traffic corridor more accurate.
[0177] This method divides the target traffic corridor into multiple target sections, calculates the ecological impact contribution rate for each target section, introduces the concept of ecological reference system, including historical ecological reference system and natural ecological reference system, determines the ecological reference system of the target section according to the construction time information of the target section, and conducts quantitative analysis of the ecological factors around the traffic corridor. This can more accurately evaluate the contribution rate of the traffic corridor to the ecological environment, more comprehensively evaluate the overall impact of the traffic corridor on the ecological environment, and avoid the subjectivity and uncertainty of qualitative analysis.
