Description

Technical Field

[0001] The present invention relates to the field of water ecological technologies, and particularly to a method for determining river treatment measures, a healthy river ecosystem, and a medium. Background Art

[0002] Currently, the restoration of damaged river ecosystems and the sustainable management of rivers have become the focus of attention. River ecosystem restoration has been carried out in many regions. However, due to the lack of an accurate understanding of river ecological environment problems and the lack of in-depth consideration of their influencing factors in terms of systematicness, hierarchy, and river restoration goals at different scales, existing river treatment and management activities often follow traditional planning and treatment concepts and technical methods, mostly still staying at the level of water pollution control and "engineering" river treatment to meet the functional requirements such as flood control and landscape of rivers, and lacking the distinction and understanding of different scales. As a result, the comprehensive improvement of river water environment and the effect of ecological restoration are not significant.

[0003] However, when observing the healthy river ecosystem in the water ecological function zoning, it is often hesitant in selecting the river conditions in some places, which makes it easy to cause difficulties in selection. At the same time, when the selection is completed, the determination of whether the river has health hazards is often a one-time determination. This leads to the situation that when the river is qualified, it is considered healthy, but there may be a situation where a certain factor in the river is harmful. However, due to the qualified situation of the river, rectification cannot be carried out, so it is easy to lead to the situation that the river still has hazards after a period of time. Summary of the Invention

[0004] In view of this, the present invention provides a method for determining river treatment measures, a healthy river ecosystem, and a medium to solve the problem that when observing the healthy river ecosystem in the water ecological function zoning, the determination of whether the river has health hazards is often a one-time determination, resulting in the situation that when the river is qualified, it is considered healthy, but due to the qualified situation of the river, rectification cannot be carried out, so it is easy to lead to the situation that the river still has hazards after a period of time.

[0005] In the first aspect, the present invention provides a method for determining river treatment measures, which includes:

[0006] Obtain a first river factor set of a preset river area within the river water ecological area, where the first river factor set includes a plurality of natural factors and a plurality of social factors; use the first river factor set to determine the health and safety of the preset river area; when it is determined that the preset river area is a healthy area, extract the first river factor set to obtain a second river factor set; use the second river factor set to conduct a secondary determination of the health and safety of the preset river area; when it is determined that the preset river area is a hazardous area, use the second river factor set to determine the river treatment measures for the preset river area.

[0007] The method for determining river treatment measures provided by the present invention can more accurately grasp the true situation of the river within the preset river area by obtaining multiple natural factors and multiple social factors, avoiding the problems of incomplete treatment and poor effects caused by ignoring certain factors. Further, after determining the health and safety of the preset river area, if it is determined to be a healthy area, a secondary determination is continued, which can more accurately identify whether the river is truly healthy, improving the accuracy of judging the health status of the river, avoiding missing the prevention and treatment opportunities for potential hazards due to misjudgment, and effectively solving the misjudgment problem that may occur in the prior art with only one determination. Finally, when the secondary determination is a hazard area, the second river factor set can accurately determine the corresponding river treatment measures for the specific factors causing the river ecological hazard, thereby being able to more effectively solve the river ecological problem, improve the treatment efficiency, reasonably allocate treatment resources, avoid resource waste, better realize the restoration and protection of the river ecosystem, and ensure the long-term health and ecological safety of the river.

[0008] In an alternative embodiment, determining the health and safety of the preset river area using the first river factor set includes:

[0009] Determining a historical river factor change set of the preset river area based on the first river factor set; determining the health and safety of the preset river area according to the historical river factor change set.

[0010] The method for determining river treatment measures provided by the present invention can capture the change trend of the preset river area over a long time span by determining the historical river factor change set through the first river factor set, avoiding the problem of ignoring potential hazards brought by long-term evolution while only focusing on the current state. Further, determining the health and safety according to the historical river factor change set greatly enhances the reliability of the determination compared with the determination relying solely on current factors.

[0011] In an alternative embodiment, when it is determined that the preset river area is a hazard area, determining the river treatment measures of the preset river area using the second river factor set includes:

[0012] When it is determined that the preset river area is a hazard area, extracting the second river factor set to obtain a third river factor set; sorting the river factors in the third river factor set according to a preset sorting order to obtain a fourth river factor set, where the preset sorting order is used to represent the severity of the harm caused by each river factor in the third river factor set to the river; determining the river treatment measures of the preset river area according to the fourth river factor set.

[0013] The method for determining river treatment measures provided by the present invention, after determining that the preset river area is a hazard area, by extracting the second river factor set, it is possible to screen out the third river factor set that causes harm to the river from numerous influencing factors. Further, by ranking the river factors in the third river factor set according to the severity of the harm caused by each river factor to the river, it is possible to clarify the degree of harm of each factor to the river ecosystem, and thus the determined river treatment measures can be preferentially targeted at the factors with greater harm, improving the pertinence and efficiency of the treatment, avoiding waste of treatment resources, and ensuring that limited resources can be concentrated on solving the most critical river ecological problems.

[0014] In an alternative embodiment, the river factors in the third river factor set are ranked according to a preset ranking order to obtain a fourth river factor set, including:

[0015] Calculate the median value of each river factor according to the third river factor set; based on the median value of each river factor, rank the river factors in the third river factor set to obtain a fourth river factor set.

[0016] The method for determining river treatment measures provided by the present invention can convert the degree of harm of abstract river factors to the river into specific numerical values by calculating the median value of each river factor in the third river factor set. Further, ranking the river factors according to the median value of each river factor eliminates subjective randomness and is based on objective numerical values, making the ranking result more scientific and reasonable, being able to more accurately reflect the degree of influence of each factor on the river ecosystem, providing a more accurate basis for the formulation of subsequent treatment measures, and avoiding the deviation that may be brought by human subjective judgment.

[0017] In an alternative embodiment, based on the median value of each river factor, the river factors in the third river factor set are ranked to obtain a fourth river factor set, including:

[0018] Based on the third river factor set, determine the river factor corresponding to the median value of each river factor; rank and label the river factors corresponding to the median value of each river factor according to a preset ranking order to obtain a fourth river factor.

[0019] The method for determining river treatment measures provided by the present invention can clearly establish the corresponding relationship between numerical values and actual factors by determining the river factor corresponding to the median value of each river factor. Further, ranking and labeling the river factors corresponding to the median value of each river factor according to a preset ranking order further clarifies the position of each factor in the harm degree ranking, making the ranking of river factors clearer and more orderly, facilitating the formulation and implementation of subsequent treatment measures, and being able to ensure that the treatment work progresses in sequence according to the severity of the harm degree, improving the systematicness and planning of the treatment work.

[0020] In an alternative embodiment, determining the river treatment measures for the preset river area according to the fourth river factor set includes:

[0021] Obtaining the basic feature information set of the preset river area; determining the river treatment measures according to the fourth river factor set and the basic feature information set.

[0022] The method for determining river treatment measures provided by the present invention determines the river treatment measures by combining the fourth river factor set and the basic feature information set. It not only considers the factors affecting the river and their harm levels, but also fully combines the basic features of the river itself, can formulate a treatment plan more in line with the actual situation of the river, improves the feasibility and effectiveness of the treatment measures, avoids the disconnection between the treatment measures and the actual situation of the river, and thus can better realize the restoration and protection of the river ecosystem.

[0023] In an alternative embodiment, the method further includes: determining the river health degree of the preset river area according to the fourth river factor set.

[0024] The method for determining river treatment measures provided by the present invention determines the river health degree of the preset river area according to the fourth river factor set, provides a quantitative result for the evaluation of the river ecosystem, and then can help managers intuitively understand the current health status of the river, facilitate the comparison and analysis of different preset river areas, so as to allocate treatment resources more reasonably and formulate targeted long-term river ecological protection strategies, promoting the sustainable development of the river ecosystem.

[0025] In a second aspect, the present invention provides a river healthy ecosystem, which includes: an acquisition module and a processing module; the acquisition module is used to acquire the first river factor set of the preset river area within the river water ecological area and send the first river factor set to the processing module, and the first river factor set includes a plurality of natural factors and a plurality of social factors; the processing module is used to execute the method for determining river treatment measures in the first aspect or any corresponding embodiment thereof.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0037] The embodiments of the present invention provide a method for determining river treatment measures, which performs a secondary determination on the health and safety of a preset river area determined to be a healthy area to improve the accuracy of judging the river health condition and avoid missing the opportunity for preventing and dealing with potential hazards due to misjudgment.

[0038] According to an embodiment of the present invention, an embodiment of a method for determining river treatment measures is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0039] In this embodiment, a method for determining river treatment measures is provided, which can be used in, for example, Figure 4 the processing module 12 shown. Figure 1 is a flowchart of the method for determining river treatment measures according to an embodiment of the present invention. As Figure 1 shown, the process includes the following steps:

[0040] Step S101, obtain a first river factor set of a preset river area within the river water ecological area.

[0041] Among them, the river water ecological area takes the river as the core, including the river itself and a certain range of surrounding areas that interact and influence each other. Further, this river water ecological area is formed by dividing the water area of a specific area into different functional areas by comprehensively considering various factors such as the structure, function, and ecological services of the water ecosystem, as well as natural geography, climate, hydrology, and biology.

[0042] Among them, the first river factor set is used to comprehensively reflect the natural environmental background of the preset river area and the impact of human social activities on it, and can include multiple natural factors and multiple social factors that affect the health and safety of a specific preset river area in the water ecological function zoning.

[0043] Further, the natural factors can be mountain and river landforms, vegetation prosperity, climate, and soil softness, etc.; the social factors can be industry, urbanization, and agriculture, etc.

[0044] Specifically, an arbitrary river divided by zones can be selected by blind selection, and the corresponding preset river area can be selected and determined by pointing at an arbitrary position on the map with a finger.

[0045] In an alternative embodiment, one can also be randomly selected from all eligible river areas by using computer random generation, or selected according to specific research purposes or actual needs.

[0046] Further, for the selected preset river area, the corresponding first river factor set can be obtained.

[0047] Among them, for the mountains and rivers, they can be obtained from the historical exploration reports of the geological department and the topographic map update records; the vegetation prosperity data can be obtained from the vegetation monitoring materials of the local forestry department and the field investigation records of ecological research institutions; the climate data can be obtained from the historical monitoring data of meteorological stations of the meteorological department; the soil softness data can be obtained by searching relevant soil research reports, soil monitoring records of the agricultural department, etc.

[0048] Furthermore, industrial data can be obtained from the enterprise statistics of the local department of industry and information technology and the industrial pollution emission records of the environmental protection department; urbanization data can be obtained from the urban development reports of the urban planning department and the census data; agricultural data can be obtained from the crop planting statistics of the agriculture and rural affairs department, the fertilizer and pesticide use records of agricultural technology extension stations, etc.

[0049] Step S102, determine the health and safety of the preset river area by using the first river factor set.

[0050] Specifically, determine whether the ecological environment and social factors in the selected first river factor set have an impact on the health and safety of the rivers in the preset river area.

[0051] Among them, the determination method can be a determination method based on model prediction, a determination method combining expert experience and the analytic hierarchy process, a machine learning algorithm determination method, etc.

[0052] In an optional implementation manner, use the determination method based on model prediction to determine whether the ecological environment and social factors in the selected first river factor set have an impact on the health and safety of the rivers.

[0053] First, apply water ecosystem models, such as QUAL2K (water quality model), SWAT (Soil and Water Assessment Tool), etc., input the data of natural factors (such as water quality-related natural factors such as flow, water temperature, dissolved oxygen, etc., and topographic features for constructing water flow and mass transfer models) and social factors (such as industrial and agricultural pollutant emissions as pollution source inputs) in the first river factor set into the models, and use these models to simulate and predict the key indicators of the river ecosystem (such as water quality indicators, biomass, etc.).

[0054] Furthermore, compare the results predicted by the model with the known river ecological health standards or the simulation results under ideal conditions. For example, if the model predicts that the chemical oxygen demand (COD) in the river water body will continue to exceed the health standard value in the future for a period of time, or predicts that the aquatic biodiversity index in the river will be lower than the normal level, it can be determined that the health and safety of the rivers in the preset river area are threatened. If the prediction results are all within the health standard range, it can be preliminarily determined that the river is in a relatively healthy and safe state.

[0055] Step S103: when it is determined that the preset river area is a healthy area, the first river factor set is extracted to obtain a second river factor set.

[0056] Specifically, when it is determined that the preset river area is a healthy area, multiple natural factors and multiple social factors that are determined to be qualified in the first river factor set can be extracted to form a corresponding new second river factor set.

[0057] Step S104, using the second river factor set to perform a secondary determination on the health and safety of the preset river area.

[0058] Specifically, the extracted second river factor set can be used to further perform a secondary determination on the health and safety of rivers within a preset river area.

[0059] Among them, the specific determination method can refer to the process of using the first river factor set in the above step S102 of this application to determine the health and safety of rivers in a preset river area, which will not be repeated here.

[0060] Step S105, when it is determined that the preset river area is a hazardous area, the river management measures for the preset river area are determined using the second river factor set.

[0061] Specifically, when the second judgment determines that a preset river area is a hazardous area, the combination of the second river factor set can accurately determine the corresponding river management measures for the specific factors that cause river ecological hazards, thereby more effectively solving river ecological problems, improving management efficiency, reasonably allocating management resources, avoiding resource waste, and better realizing the restoration and protection of river ecosystems, thereby ensuring the long-term health and ecological security of rivers.

[0062] In an optional implementation, the second river factor set is first analyzed to determine the most critical natural and social factors that pose the greatest threat to river ecology.

[0063] Furthermore, we can conduct extensive research on relevant control technologies and methods based on the identified key hazard factors. For example, for the problem of soil erosion, we can consult the information and find out that afforestation, slope protection, and sand dam construction are all effective control methods; for the problem of industrial wastewater discharge, we can study advanced sewage treatment technologies, such as membrane separation technology, biological treatment technology, etc., as well as relevant measures to strengthen supervision and law enforcement.

[0064] Further, fully consider the actual characteristics of the preset river area, such as factors like the river flow rate, velocity, surrounding topography and landforms, and economic development level, and screen the treatment technologies and methods obtained from the research. For example, if the river has a large flow rate and high velocity, some sewage treatment technologies that require a long hydraulic retention time may not be very applicable; if the surrounding terrain is complex, there may be problems with construction difficulties and excessive costs for large-scale construction of sediment dams. After screening, determine the treatment measures suitable for the preset river area.

[0065] Further, integrate the screened treatment measures and formulate a detailed treatment plan.

[0066] Finally, experts can be organized to evaluate the formulated treatment plan, and analyze and demonstrate it from multiple perspectives such as technical feasibility, economic rationality, and environmental impact. Further, optimize and adjust the plan according to the experts' opinions to ensure that the finally formed treatment plan is scientific, reasonable, and practical.

[0067] The method for determining river treatment measures provided in this embodiment can more accurately grasp the true situation of the river within the preset river area by obtaining multiple natural factors and multiple social factors, and avoid problems such as incomplete treatment and poor effects caused by neglecting certain factors. Further, after determining the health and safety of the preset river area, if it is determined to be a healthy area, a secondary determination is continued, which can more accurately identify whether the river is truly healthy, improve the accuracy of judging the river health status, avoid missing the prevention and treatment opportunities for potential hazards due to misjudgment, and effectively solve the misjudgment problem that may occur in the prior art with only one determination. Finally, when the secondary determination is a hazard area, the second river factor set can be used to accurately determine the corresponding river treatment measures for the specific factors causing the river ecological hazard, thereby being able to more effectively solve the river ecological problem, improve the treatment efficiency, reasonably allocate treatment resources, avoid resource waste, better realize the restoration and protection of the river ecosystem, and ensure the long-term health and ecological safety of the river.

[0068] In this embodiment, a method for determining river treatment measures is provided, which can be used in, for example, Figure 4 the processing module 12 shown Figure 2 is a flowchart of the method for determining river treatment measures according to an embodiment of the present invention, as shown in Figure 2 shown, and this process includes the following steps:

[0069] Step S201, obtain the first river factor set of the preset river area within the river ecological area. For details, please refer to Figure 1 step S101 of the embodiment shown, which will not be elaborated here.

[0070] Step S202, use the first river factor set to determine the health and safety of the preset river area.

[0071] Specifically, the above step S202 includes:

[0072] Step S2021, determining a historical river factor change set of a preset river area based on the first river factor set.

[0073] Specifically, the time span of the historical river factor change set can be determined first, such as data from the past 5-10 years, to ensure that the data can reflect recent change trends and have a certain time length for analysis.

[0074] Furthermore, according to the determined time span, multiple natural factors and multiple social factors within the time span can be obtained respectively, and the changes of natural factors and social factors can be statistically analyzed to form a corresponding historical river factor change set.

[0075] In an optional implementation, historical data related to the first river factor set is first collected from various data sources, where the data sources may be long-term monitoring records of local environmental protection departments, water conservancy departments, meteorological stations, agricultural bureaus, and other institutions, as well as data related to the preset river area in academic research literature.

[0076] Furthermore, the historical data collected on natural factors (such as mountains and rivers, vegetation prosperity, climate, soil softness) and social factors (such as industry, urbanization, and agriculture) can be integrated with the data in the first river factor set in chronological order. For example, the annual precipitation data of the past ten years and the precipitation data of the current year in the first river factor set can be put together to form a complete precipitation data sequence.

[0077] Secondly, the integrated historical data can be screened to remove obviously erroneous or abnormal data points. For example, if it is found that the industrial pollutant emissions data for a certain year is significantly higher than those for other years and does not match the actual situation, after verification, the data can be regarded as an outlier and removed.

[0078] Furthermore, missing data can be supplemented or estimated. For some small amounts of missing data, linear interpolation, moving average and other methods can be used for estimation. For example, if the vegetation coverage data for a certain year is missing, the vegetation coverage for that year can be estimated by linear interpolation based on the data for the two years before and after.

[0079] Finally, the filtered and cleaned data can be sorted and classified according to natural and social factors, and a historical river factor change set can be constructed. The historical river factor change set contains the values of each factor at different time points to clearly show the changing trends of various factors over time. For example, for climate factors, the historical river factor change set should include data such as temperature, precipitation, and wind speed over the years to form a time series data set, intuitively reflecting the changes in climate.

[0080] Step S2022, determine the health and safety of the preset river area according to the historical river factor change set.

[0081] Specifically, based on the professional knowledge in the field of river ecology, relevant industry standards, and the historical average data of the rivers in this area, change determination criteria can be set for each natural and social factor, that is, to determine what kind of change range can be considered "a large change".

[0082] For example, for the vegetation coverage rate, it is set that if it drops by more than 10% within 5 years, it is considered that the vegetation prosperity has changed greatly; for industrial pollutant emissions, if the emissions of a certain type of main pollutant increase by more than 50% within 3 years, it is determined to be a large change.

[0083] Furthermore, observe one by one the numerical changes of each natural and social factor in the historical river factor change set and compare them with the set change determination criteria.

[0084] For example, in terms of natural factors, check whether there are significant changes in the mountain and river landforms, such as whether there are large-scale landslides causing river channel blockage or diversion. If such a situation occurs, it is obviously a large change; observe whether the numerical changes of factors such as vegetation coverage rate, climate indicators, and soil softness exceed the set standards; in terms of social factors, pay attention to the changes in the number, scale, and pollutant emissions of industrial enterprises, the changes in urbanization process indicators, and the changes in agricultural planting structure, fertilizer and pesticide usage, etc., to judge whether they reach or exceed the set standards for large changes.

[0085] Furthermore, if only individual factors show large changes and have little impact on the river ecosystem among natural and social factors, it can be preliminarily determined that the river in the preset river area is in a relatively healthy and safe state, that is, the preset river area is a healthy area.

[0086] Further, if multiple natural or social factors change significantly, and these changes have a negative impact on the basic characteristics of the river (such as water quality, water volume, river channel morphology) and the ecological environment (such as biodiversity, habitat quality), for example, the water quality deteriorates due to increased industrial pollution emissions, and the vegetation coverage rate decreases, leading to soil erosion and affecting the river channel stability, etc., then it is determined that the health and safety of the river in the preset river area are threatened, that is, the preset river area is a hazard area.

[0087] Further, by comprehensively considering the changes of the above factors and their interactions, a comprehensive and accurate determination of the health and safety status of the river in the preset river area can be made.

[0088] Step S203, when it is determined that the preset river area is a healthy area, extract the first river factor set to obtain the second river factor set.

[0089] Specifically, when it is determined that the preset river area is a healthy area, according to the significantly changed values observed in the river in step S202, extract the significantly changed values, and at the same time extract the basic information in the corresponding natural factor changes and social factor changes of the significantly changed values, and form the corresponding second river factor set.

[0090] Step S204, use the second river factor set to make a secondary determination of the health and safety of the preset river area.

[0091] Specifically, the second river factor set obtained by extraction can be used to continue to determine the health and safety of the river in the preset river area.

[0092] Among them, the specific determination method can refer to the process of using the first river factor set to determine the health and safety of the river in the preset river area in step S202 of the present application, which will not be elaborated here.

[0093] Step S205, when it is determined that the preset river area is a hazard area, use the second river factor set to determine the river treatment measures for the preset river area. For details, please refer to Figure 1 Step S105 of the illustrated embodiment, which will not be elaborated here.

[0094] The river treatment measure determination method provided in this embodiment can determine the historical river factor change set through the first river factor set, capture the change trend of the preset river area over a long time span, and avoid the problem of only focusing on the current state and ignoring the potential hazards brought by long-term evolution. Further, making a health and safety determination based on the historical river factor change set greatly enhances the reliability of the determination compared to simply relying on the current factors.

[0095] In this embodiment, a river treatment measure determination method is provided, which can be used for such asFigure 4 The processing module 12 shown Figure 3 is a flowchart of a method for determining river treatment measures according to an embodiment of the present invention. As Figure 3 shown, the process includes the following steps:

[0096] Step S301, obtain a first river factor set for a preset river area within the river ecological area. For details, please refer to Figure 1 Step S101 of the embodiment shown, which will not be elaborated here.

[0097] Step S302, determine the health and safety of the preset river area by using the first river factor set. For details, please refer to Figure 2 Step S202 of the embodiment shown, which will not be elaborated here.

[0098] Step S303, when it is determined that the preset river area is a healthy area, extract the first river factor set to obtain a second river factor set. For details, please refer to Figure 2 Step S203 of the embodiment shown, which will not be elaborated here.

[0099] Step S304, perform a secondary determination on the health and safety of the preset river area by using the second river factor set. For details, please refer to Figure 2 Step S204 of the embodiment shown, which will not be elaborated here.

[0100] Step S305, when it is determined that the preset river area is a hazardous area, determine the river treatment measures for the preset river area by using the second river factor set.

[0101] Specifically, the above step S305 includes:

[0102] Step S3051, when it is determined that the preset river area is a hazardous area, extract the second river factor set to obtain a third river factor set.

[0103] Specifically, after the secondary determination that the preset river area is a hazardous area, multiple natural factors and multiple social factors determined to be unqualified in the second river factor set can be extracted and a corresponding new third river factor set can be formed.

[0104] Step S3052, sort the river factors in the third river factor set according to a preset sorting order to obtain a fourth river factor set.

[0105] Among them, the preset sorting order is used to represent the severity of the harm caused by each river factor in the third river factor set to the river within the preset river area.

[0106] In some alternative embodiments, the above step S3052 includes:

[0107] Step a1, calculating the median value of each river factor according to the third river factor set.

[0108] Step a2: sorting the river factors in the third river factor set based on the median value of each river factor to obtain a fourth river factor set.

[0109] Specifically, for each natural factor and social factor in the third river factor set, find and determine its highest and lowest values ​​in the third river factor set. For example, when counting the vegetation coverage change data in the past few years, it was found that the highest coverage was 80% and the lowest coverage was 60%.

[0110] Furthermore, the highest value of the natural factor change is subtracted from the lowest value to obtain the difference of the natural factor; then the lowest value of the natural factor plus half of the difference can be used to calculate the median value of the natural factor. Similarly, the median value of the social factor can be calculated and obtained.

[0111] Furthermore, for each specific data in the changes of natural factors and social factors, their corresponding intermediate values ​​are calculated according to the proportional relationship of the intermediate values ​​calculated above.

[0112] Furthermore, the corresponding intermediate values ​​of each item in the changes of natural factors and social factors are summarized together, and the summarized intermediate values ​​are arranged in order from large to small.

[0113] Finally, based on the arrangement results, the river factors in the third river factor set are sorted and the fourth river factor set is obtained.

[0114] In some optional implementations, the above step a2 includes:

[0115] Step a21, based on the third river factor set, determine the river factor corresponding to the middle value of each river factor.

[0116] Step a22, sorting and numbering the river factors corresponding to the middle value of each river factor according to a preset sorting order to obtain a fourth river factor.

[0117] Specifically, based on the arrangement results, basic information on the changes in natural factors and social factors corresponding to the middle values ​​is found in the third river factor set and a corresponding fourth river factor set is formed.

[0118] Furthermore, according to the severity of the harm caused by each river factor to the river, the median value is used as a quantitative indicator to measure the degree of harm. The larger the median value, the more serious the harm caused by the factor to the river.

[0119] Further, sort each of the fourth river factors according to a preset sorting order, that is, arrange the preset sorting order in descending order of the median value. For example, among all the calculated median values of the river factors, if the median value of industrial pollutant emissions is the largest at 600 tons / year and the median value of vegetation coverage rate is the second largest at 70%, then the factor corresponding to industrial pollutant emissions is ranked first, and the factor corresponding to vegetation coverage rate is ranked behind it, and so on to complete the sorting of all factors.

[0120] Further, starting from 1, number each river factor in the sorted order. The factor of industrial pollutant emissions ranked first is numbered 1, the factor of vegetation coverage rate ranked second is numbered 2, and so on until all river factors are numbered. The finally formed set of river factors with numbers and sorted according to the severity of harm is the fourth river factor set. Therefore, through this fourth river factor set, the relative severity order of the harm of each river factor to the river can be clearly seen, providing a clear basis for determining subsequent treatment measures.

[0121] Step S3053, determine the river treatment measures for the preset river area according to the fourth river factor set.

[0122] In some alternative embodiments, the above step S3053 includes:

[0123] Step b1, obtain the basic feature information set of the preset river area.

[0124] Step b2, determine the river treatment measures according to the fourth river factor set and the basic feature information set.

[0125] Among them, the basic feature information set represents a comprehensive information set that comprehensively reflects the inherent characteristics of the preset river area and the surrounding related situations, and may include natural geographical features (topography and landforms, soil types, etc.), hydrological features (flow rate and velocity, water level changes, water temperature and water quality, etc.), surrounding environmental features (land use types, population distribution status, special area situations, etc.), and so on.

[0126] Specifically, through research and analysis of the fourth river factor set, and according to the forward numbers, clarify the natural factor changes and social factor changes that are most harmful to the river. For example, the factor numbered 1 may be serious water quality pollution caused by industrial wastewater discharge, and the factor numbered 2 may be soil erosion problems caused by vegetation damage. By determining the specific situation and influence degree of each factor, it provides a direction for formulating targeted treatment measures.

[0127] Furthermore, the fourth river factor set can be combined with the basic feature information set of the preset river area. For example, if the river is located in a mountainous area with large terrain undulations, for the problem of soil erosion caused by vegetation damage, treatment measures can consider building terraced fields on the slopes, planting slope protection plants, etc., and using the terrain characteristics for soil and water conservation; if there are large areas of farmland around the river, for the problem of agricultural non-point source pollution, ecological agricultural technologies such as precision fertilization and reasonable irrigation can be promoted to reduce the use of chemical fertilizers and pesticides. At the same time, ecological ditches can be built to purify the farmland drainage.

[0128] Furthermore, by comprehensively considering the above factors, the most suitable river treatment measures for this area can be formulated.

[0129] Furthermore, the river treatment measures can also be arranged according to the basic situations of the most harmful natural factor changes and social factor changes. Therefore, the ones at the front of the treatment plan can correspond to the intermediate values of the corresponding natural factor changes and various intermediate values in the social factors, and are arranged in descending order of the intermediate values. And according to the corresponding basic information in the natural factor changes and social factor changes, the basic information is arranged from high to low accordingly, and the corresponding basic information is numbered correspondingly.

[0130] Furthermore, according to the obtained treatment measures and plans, the natural factor changes and social factor changes with the greatest harm can be given priority in treatment, so that the factors with the greatest harm in this basin can be solved preferentially, to a certain extent avoiding the deterioration of the river health and safety in this area, ensuring the safety of the river. Then, through subsequent treatment of other factors in sequence according to the numbers and arrangements in the plan, the situation of river deterioration can be gradually controlled, ensuring that the health of the river can be quickly restored.

[0131] Furthermore, after using step S302 for a determination, if it is determined that the preset river area is a hazardous area, then directly execute the above step S305.

[0132] Furthermore, after using step S304 for a secondary determination, if it is determined that the preset river area is a healthy area, then finally determine that the preset river area is a healthy area and no treatment is required.

[0133] In an optional implementation manner, after the above step S3052, it further includes: determining the river health degree of the preset river area according to the fourth river factor set.

[0134] Specifically, find and respectively determine the factors with the highest and lowest harm degrees to the river from the fourth river factor set.

[0135] Furthermore, the factors with the highest and lowest hazards determined according to a certain scoring criterion can be assigned corresponding scores. For example, a score range of 0 - 100 can be set. For the factor with the highest hazard, a relatively high score is given according to its severity, such as 90 points (assuming that severe pollution has a great harm to the river and a relatively high score can be given in a system with a full score of 100); for the factor with the lowest hazard, a relatively low score is given according to its minor impact on the river, such as 10 points (assuming that good vegetation prosperity has a positive effect on river health, so the score is low).

[0136] Furthermore, the scores of the factor with the highest hazard and the factor with the lowest hazard can be added together and then divided by 2 to calculate the average value.

[0137] Furthermore, the calculated average value can be used to judge the river health status of the basin by referring to the pre-set river health level grading criteria. For example, the following grading criteria can be set:

[0138] (1) 80 - 100 points: The river health status is good and the harm suffered is small.

[0139] (2) 60 - 79 points: The river health status is average and there are certain degrees of harm that need attention.

[0140] (3) 40 - 59 points: The river health status is poor, the harm suffered is relatively obvious, and treatment measures need to be taken.

[0141] (4) 0 - 39 points: The river health status is extremely poor, facing serious harm problems, and urgent and intensive treatment is needed.

[0142] The method for determining river treatment measures provided in this embodiment can, after determining that a preset river area is a hazard area, screen out a third river factor set that harms the river from numerous influencing factors by extracting the second river factor set. Further, by calculating the median value of each river factor in the third river factor set, the degree of harm of abstract river factors to the river can be converted into specific numerical values. Further, by determining the river factors corresponding to the median value of each river factor, a clear correspondence between the numerical values and the actual factors can be established. Further, sorting and numbering the river factors corresponding to the median value of each river factor according to the preset sorting order further clarifies the position of each factor in the harm degree ranking, making the ranking of river factors clearer and more orderly, facilitating the formulation and implementation of subsequent treatment measures, ensuring that the treatment work progresses in sequence according to the severity of the harm degree, and improving the systematicness and planning of the treatment work. Further, by determining river treatment measures in combination with the fourth river factor set and the basic feature information set, not only the factors affecting the river and their harm degrees are considered, but also the basic features of the river itself are fully combined, enabling the formulation of a treatment plan that better suits the actual situation of the river, improving the feasibility and effectiveness of the treatment measures, avoiding the disconnection between the treatment measures and the actual situation of the river, and thus being able to better achieve the restoration and protection of the river ecosystem.
