Description

Technical Field

[0001] The present invention relates to the technical field of intelligent city planning, and in particular to a system and method for automatically correcting a high-efficiency urban planning floor area ratio. Background Art

[0002] The floor area ratio refers to the ratio of the total building area to the building land area within a certain plot. The floor area ratio reflects the intensity of development and is an indicator frequently studied in the field of urban planning. In the process of planning the floor area ratio of a single plot, it is necessary to comprehensively consider many factors such as the location of the plot, the influence of natural topography and landforms, the size of the plot, the surrounding public transportation support, the population, and the nature of the plot; the floor area ratio planning at the scale of the entire city also needs to consider the entire city’s population size, the total amount of urban development, and other issues for macro-coordination. The implementation process of the above research requires the use of big data computing and analysis. In the traditional urban planning process, planning practitioners generally use AutoCAD and PhotoShop tools, so they often directly set the floor area ratio of a certain area based on the location of the plot and the overall planning arrangement.

[0003] In recent years, planning practitioners have gradually begun to use ArcGiS tools and use Arc MAP software for calculations. However, the current use of ArcGiS existing calculation tools for plot ratio research is based on the various attributes of the plot and uses specific rules to conduct detailed research and setting of the plot ratio, which involves calculating a large number of graphic patches and corresponding attribute data. However, a single calculation process using ArcGis tools takes a very long time, and because each link requires calling different ArcGis calculation processes, the intermediate calculation results need to be manually screened or scripted before subsequent calls, which makes the entire corrected plot ratio calculation process extremely time-consuming. For planning practitioners who are proficient in using ArcGis tools, it still takes 3-5 working days, and too much manual participation in calculations can easily lead to omissions and errors in calculations. Summary of the invention

[0004] The technical problem solved by the present invention is to provide an efficient automatic correction system and method for urban planning floor area ratio, which aims to avoid omissions, errors and time-consuming calculations caused by excessive manual participation of planning practitioners when calculating the floor area ratio in urban planning.

[0005] The basic solution provided by the present invention is:

[0006] An automatic correction system for urban planning floor area ratio, comprising:

[0007] Data import module, importing given area plots, intensity units and track influence range files;

[0008] A preprocessing module, which standardizes the fields of the given area plot, intensity unit and track influence range files imported by the data import module to obtain standardized spatial and attribute data;

[0009] A spatial relationship processing module, which obtains spatial intersection relationships of different types of data files based on the data files standardized by the preprocessing module;

[0010] The rule engine module obtains the base plot ratio, each single plot ratio correction factor, commercial-residential ratio factor and track correction factor through a preset rule set according to the spatial intersection relationship obtained by the spatial relationship processing module and the plot attributes of a given area;

[0011] The floor area ratio correction module corrects the floor area ratio according to the base floor area ratio, each single floor area ratio correction coefficient, the commercial-residential ratio coefficient and the track correction coefficient, and calculates the comprehensive floor area ratio, commercial floor area ratio and residential floor area ratio of the plot in a given area.

[0012] The principle of the basic scheme of the present invention is:

[0013] To solve the problem that it takes a long time for planning practitioners to use ArcGis tools to calculate the plot ratio of land, and too much manual participation in the calculation can easily lead to omissions and errors in the calculation. In this solution, planning practitioners use the preprocessing module to standardize the given regional plots, intensity units and track influence range files imported by the data import module. For example, each data intensity unit processed by the system uses hectares as the area unit to obtain standardized space and attribute data; the spatial relationship processing module obtains the spatial intersection relationship between the given regional plots, intensity units and track influence range data files based on the standardized data files, and calculates the benchmark floor area ratio, each single floor area ratio correction factor, commercial and residential ratio factor and track correction factor through the preset rule set based on this spatial intersection relationship and the given regional plot attributes; that is, according to the intensity unit strength, the area of ​​the given regional plot, the distance from the track station, the commercial / residential and other attributes, the correction coefficients of the floor area ratio corresponding to each rule under the preset rule set are calculated respectively, and finally the floor area ratio of the given regional plot is corrected according to the calculated correction coefficients, and the comprehensive floor area ratio, commercial floor area ratio and residential floor area ratio of the given regional plot are calculated, that is, the correction result of the floor area ratio data involved in the output is output.

[0014] It should be noted that the orbital influence range information refers to the orbital radiation range in the given regional plots; the floor area ratios and correction factors corresponding to each rule under the preset rule set calculated by this scheme specifically include the benchmark floor area ratio, area correction factor, orbital correction factor, the proportion of commercial and residential properties in the given regional plots, the benchmark commercial floor area ratio and the benchmark residential floor area ratio, that is, each individual floor area ratio correction factor includes the area correction factor, the benchmark commercial floor area ratio and the benchmark residential floor area ratio; the various rules under the preset rule set include area rules, commercial and residential rules, orbital influence rules and other rules.

[0015] The beneficial effects of the basic solution are:

[0016] (1) In this scheme, the efficient urban planning floor area ratio automatic correction system includes a data import module, a preprocessing module, a spatial relationship processing module, a rule engine module and a floor area ratio correction module, which realizes the automatic acquisition and processing of plots in a given area, and automatically corrects and outputs the floor area ratios of the plots in the given area, thereby avoiding the problem of omissions, errors and time-consuming floor area ratio calculations caused by excessive manual participation in calculations.

[0017] (2) In this solution, the efficient urban planning floor area ratio automatic correction system can be supported and run by the computing power of ordinary personal computers and notebooks, without relying on large servers. The system imports the corresponding given area plots, intensity units, and track influence range data and completes the calculation with one click. The output result data includes the floor area ratio correction coefficients, comprehensive floor area ratio, commercial floor area ratio, residential floor area ratio, etc. in the process, making this solution for urban planning floor area ratio correction faster, more convenient, and more systematic.

[0018] (3) In this solution, the efficient urban planning floor area ratio automatic correction system can be used as a plug-in and added through ArcGisToolBox. It is easy to install and similar to the use of system tools, which is in line with the usage habits of planning practitioners.

[0019] (4) In this scheme, the benchmark floor area ratio of a given regional plot is obtained based on the intensity transmission of the intensity unit, so that the overall intensity of the city in the plan can be transmitted to the specific regional plots. The same plot obtains the commercial floor area ratio and the residential floor area ratio respectively, which improves the refined control of the intensity unit strength and makes the floor area ratio calculation more accurate.

[0020] Furthermore, the given area plots, intensity units and track influence range files all support layer, graphic SHP and geographic information database GDB formats.

[0021] The efficient urban planning floor area ratio automatic correction system is based on the ArcGis tool. The various types of data files imported support multiple common geographic information formats such as layer Layer, graphic SHP, geographic information database GDB, etc., making the system suitable for regional calculations of various scales and a wide range of applications.

[0022] Furthermore, the preprocessing module is also used to encode non-data fields, so that the rule engine module can calculate the base plot ratio, each single plot ratio correction factor, commercial-residential ratio factor and track correction factor, and the plot ratio correction module can calculate the comprehensive plot ratio, commercial plot ratio and residential plot ratio of a given area plot.

[0023] Furthermore, the spatial relationship processing module is used to assign the intensity of the intensity unit to the plot according to the spatial relationship between the plot and the intensity unit in the given area, and to process the intersection relationship between the plot and the influence interval of the rail station in different range scales.

[0024] The spatial relationship between the given regional plot and the intensity unit is obtained through the spatial relationship processing module, and the intensity of the intensity unit is assigned to the given regional plot to avoid confusion in the inheritance of the intensity unit, that is, to avoid cross-inheritance caused by different intensity units, which leads to confusion in the data of the given regional plot in the intensity unit. At the same time, the spatial intersection relationship between the given regional plot and the track influence range is processed to facilitate the calculation of the benchmark volume ratio, each single volume ratio correction factor, commercial and residential ratio factor and track correction factor by the rule engine module.

[0025] Furthermore, the centroid of the land parcel in the given area is used as the position feature of the land parcel in the given area.

[0026] The centroid of the given regional plot is used as the location feature of the given regional plot, so that the intersection with the intensity unit is unique, avoiding the randomness of the intensity inheritance of the intensity unit.

[0027] Furthermore, the preset rule set includes intensity-floor area ratio benchmark correspondence standards, plot commercial and residential type-commercial / residential ratio standards, area-commercial / residential-floor area ratio correction standards and track floor area ratio correction standard rules.

[0028] The rule engine module is used to calculate the benchmark floor area ratio, area correction factor, track correction factor, the proportion of commercial and residential areas in a given area, the benchmark commercial floor area ratio and the benchmark residential floor area ratio according to the spatial intersection relationship and the attributes of the plots in a given area, as well as the strength-floor area ratio benchmark corresponding standard, the plot commercial and residential type-commercial / residential ratio standard, the area-commercial / residential-floor area ratio correction standard, and the track floor area ratio correction standard rules. Based on this, the system can calculate the correction coefficient for the floor area ratio under each rule in the preset rule set.

[0029] Furthermore, the efficient urban planning floor area ratio automatic correction system also includes:

[0030] The building area calculation module is used to calculate the commercial building area, residential building area and comprehensive building area of ​​the given area plot according to the given area plot area, comprehensive floor area ratio, commercial floor area ratio and residential floor area ratio.

[0031] The building area calculation module can be used to calculate the commercial building area, residential building area and comprehensive building area of ​​a given area, which will help planning practitioners better understand the commercial buildings, residential buildings, etc. in a given area, and make macro-coordinated considerations on issues such as the entire city's population size and total urban development.

[0032] Furthermore, the efficient urban planning floor area ratio automatic correction system also includes:

[0033] The information storage module is used to store the benchmark floor area ratio, each single floor area ratio correction factor, commercial-residential ratio factor and track correction factor obtained by the rule engine module, as well as the comprehensive utilization rate, commercial and comprehensive floor area ratio in the floor area ratio correction module.

[0034] The information storage module stores various data such as the benchmark floor area ratio, individual floor area ratio correction coefficients, commercial-residential ratio coefficient and track correction coefficient, comprehensive utilization rate, commercial and comprehensive floor area ratio calculated by the efficient urban planning floor area ratio automatic correction system, so that planning practitioners can query and retrieve data on plots in a given area when they need it.

[0035] In addition, to achieve the above purpose, the present invention also proposes an efficient urban planning floor area ratio automatic correction method, which is based on the above system and includes the following steps:

[0036] Import given area plots, intensity units and track influence range files;

[0037] Standardizing the fields of the given area plot, intensity unit and track influence range files to obtain standardized spatial and attribute data;

[0038] According to the processed data files, spatial intersection relations of data files of different types are obtained;

[0039] Based on the obtained spatial intersection relationship and the properties of the plots in a given area, the base plot ratio, each single plot ratio correction factor, commercial-residential ratio factor and track correction factor are obtained through a preset rule set;

[0040] Each individual floor area ratio is corrected according to the benchmark floor area ratio, each individual floor area ratio correction coefficient, the commercial-residential ratio coefficient and the track correction coefficient, and the comprehensive floor area ratio, commercial floor area ratio and residential floor area ratio of the land in a given area are calculated.

[0045] The following is further described in detail through specific implementation methods:

[0046] In one embodiment, referring to Figure 1 As shown, it is a flow chart of the method for automatic correction of efficient urban planning volume ratio, which is based on the automatic correction system for efficient urban planning volume ratio. This system can be directly installed in a computer, and the memory of the storage medium in the computer may include an operating system, a network communication module, a user interface module, and a distributed task processing program. Among them, the operating system is a program for managing and controlling the hardware and software resources of the sample terminal device, and supports the operation of the distributed task processing program and other software or programs.

[0047] In the terminal device, the user interface is mainly used for data communication with each terminal; the network interface is mainly used for connecting to the backend server and communicating with the backend server; and the processor can be used to call the recognition program for automatic correction of efficient urban planning floor area ratio stored in the memory and execute the following steps: Figure 1 The following operations are shown:

[0048] Step S100, importing a given area plot, intensity unit and track influence range file;

[0049] Step S200, standardizing the fields of the given area plot, intensity unit and track influence range file to obtain standardized spatial and attribute data;

[0050] Step S300, obtaining spatial intersection relations of data files of different types according to the processed data files;

[0051] Step S400, based on the obtained spatial intersection relationship and the given area plot attributes, the base plot ratio, each single plot ratio correction factor, commercial-residential ratio factor and track correction factor are obtained through a preset rule set;

[0052] Step S500, correcting each individual floor area ratio according to the base floor area ratio, each individual floor area ratio correction coefficient, commercial-residential ratio coefficient and track correction coefficient, and calculating the comprehensive floor area ratio, commercial floor area ratio and residential floor area ratio of the plot in the given area.

[0053] The embodiment of the present invention provides an embodiment of an efficient urban planning floor area ratio automatic correction method. It should be noted that although the logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that shown here.

[0054] In practical applications, refer to Figure 2 As shown, the efficient urban planning floor area ratio automatic correction system includes:

[0055] A data import module 10 is used to import a given area plot, intensity unit and track influence range file;

[0056] A preprocessing module 20 standardizes the fields of the given area plot, intensity unit and track influence range file imported by the data import module 10 to obtain standardized spatial and attribute data;

[0057] A spatial relationship processing module 30, which obtains spatial intersection relationships between data files of different types based on the data files processed by the preprocessing module 20;

[0058] The rule engine module 50 obtains the base plot ratio, each single plot ratio correction factor, the commercial-residential ratio factor and the track correction factor through a preset rule set according to the spatial intersection relationship obtained by the spatial relationship processing module 30 and the plot attributes of a given area;

[0059] The floor area ratio correction module 60 corrects the floor area ratio according to the base floor area ratio, each single floor area ratio correction coefficient, the commercial-residential ratio coefficient and the track correction coefficient, and calculates the comprehensive floor area ratio, commercial floor area ratio and residential floor area ratio of the plot in a given area.

[0060] In one embodiment, the efficient urban planning volume ratio automatic correction system is implemented in the form of an ArcGis plug-in. By packaging the plug-in into the ArcGis toolbox tbx format, the format file can be directly added to the program on a computer with ArcGis software installed, and appears in the system toolbox after addition. The plug-in is made by the ArcGis official tool, and the threshold for using the system is lowered by combining the Python script that implements the system function with the visual input and output interface.

[0061] In this embodiment, a spatial connection method is adopted between the given area plots and the intensity units imported by the data import module 10, that is, the corresponding spatial relationships between the given area plots and the intensity units in the actual geographical area positions are connected, which greatly improves the efficiency of the system in processing spatial relationships compared to the connection of intersection relationships.

[0062] Refer to Figure 2 As shown, there are eight modules, including data import module 10, preprocessing module 20, spatial relationship processing module 30, track correction module 40, rule engine module 50, volume ratio correction module 60, building area calculation module 70 and information storage module 80. Only data import module 10 requires user operation. Planning practitioners select the required regional plots, intensity units and track data, and select the cache file directory as the storage location of some intermediate results in the process for later reference. After the selection is completed, click OK to start the calculation.

[0063] It should be noted that the intensity unit in this plan refers to the division of the central urban area into multiple intensity unit areas. Taking the central urban area of ​​Chongqing as an example, the central urban area is divided into 5 intensity levels, namely intensity unit area 1, intensity unit area 2, intensity unit area 3, intensity unit area 4 and intensity unit area 5. Intensity unit areas 1 and 2 are mainly the core areas of the Two Rivers and Four Banks, traditional business districts and surrounding areas, cluster centers and surrounding areas, comprehensive transportation hubs and surrounding areas, important rail transit nodes and surrounding areas; intensity unit area 5 is mainly the "Two Rivers and Four Banks" area outside the inner ring, the surrounding areas of important urban mountains, the "Four Mountains" and their surrounding areas, traditional style areas, historical and cultural blocks and surrounding areas; intensity units 3 and 4 are other urban areas. The benchmark floor area ratio and floor area ratio control range of residential and commercial land in multiple intensity unit areas are set according to actual conditions. For example, in this plan, the benchmark floor area ratio of intensity unit area one can be 2.5; the benchmark floor area ratio of intensity unit area two can be 2.5, which can control the floor area ratio below 3.75; the benchmark floor area ratio of intensity unit area three can be 2.0, which can control the floor area ratio below 3.0; the benchmark floor area ratio of intensity unit area four can be 1.5, which can control the floor area ratio below 1.2; the benchmark floor area ratio of intensity unit area five can be 2.5, which can control the floor area ratio below 1.8.

[0064] In one embodiment, referring to Figure 3 As shown, the preprocessing module 20 standardizes the fields of the given area plot, intensity unit and track influence range file imported by the data import module 10 to obtain standardized space and attribute data, which can be specifically

[0065] (1) Data standardization. For example, if the area is measured in hectares in the rules for correcting the floor area ratio based on area, then the area of ​​the plots in a given area needs to be converted into units.

[0066] (2) Add the fields with operations involved in the subsequent calculation process, which include the output fields required for the final result output and the process fields required during the processing.

[0067] (3) Non-numeric field coding is used for subsequent calculations. The coding of non-numeric fields includes three parts. The first is to encode the intensity from a string form such as a high-intensity zone to an integer. The second is the coding of the classification name of urban construction land. The value of this field is relatively complex. There are many optional values ​​in the test data, a total of 7,860, which is not conducive to subsequent calculations. Therefore, based on the basic format of the field value feature *_*_(commercial)(residential), this field is recoded into four categories, namely residential land, commercial land, residential and commercial land, and commercial and residential land, and mapped to positive integers respectively. The third is the coding of the rail coverage range. For rail stations, ordinary stations and transfer stations are distinguished. The rail influence range gradually decays with distance. On the one hand, it is difficult to accurately calculate the decay rate. On the other hand, the calculation amount increases greatly during the subsequent floor area ratio correction. Therefore, this scheme chooses to normalize the intervals. It can be defined that the 300-meter range is the core range of the station influence, the 600-meter range is affected to a certain extent, and the range beyond 600 meters is not affected.

[0068] In one embodiment, the spatial relationship calculation module mainly calculates two spatial relationships:

[0069] (1) Given the spatial relationship between the regional plot and the intensity unit, determine which intensity unit the given regional plot is included in. It should be noted here that since there are generally many plots and intensity units in a given regional plot, it takes a long time to use intersection and then assign the intensity of the intensity unit to the given regional plot based on the intersection result; therefore, this solution uses the spatial connection in the ArcGis tool to directly assign the intensity of the intensity unit to the associated given regional plot based on the relative position in space. In addition, for plots that span multiple intensity units, the centroid of the plot is used as the criterion for judging the intersection with the intensity unit during the spatial connection process, which can effectively avoid the randomness of the intersection judgment.

[0070] (2) Given the spatial relationship between the regional land parcel and the track, since the influence range of the track is defined as 300 meters and 600 meters in the above embodiment, the two influence ranges of the regional land parcel and the track are spatially connected respectively, and finally the codes of the influence range and the track type are assigned to the intersecting land parcels.

[0071] In one embodiment, referring to Figure 2 As shown, the efficient urban planning floor area ratio automatic correction system also includes a track correction module: in the process of correcting the floor area ratio of a given area through track coverage, it is necessary to pay attention to the overlap of different track stations and influence ranges of different scales. For overlapping situations, the overlapping area or regional influence can be maximized. This system adopts the regional influence to take the maximum value, the influence factor is set to be greater than the type, and the transfer station 300 meters is greater than the ordinary station 300 meters, the ordinary station 300 meters is greater than the transfer station 600 meters, and the transfer station 600 meters is greater than the ordinary station 600 meters. Finally, the impact of different types of track coverage in different ranges is converted into a single factor problem, and the intersection relationship value is assigned to the given area plot.

[0072] In one embodiment, referring to Figure 4 As shown, the rule engine module 50 mainly includes commercial-residential ratio allocation rules based on classification, as well as strength-floor area ratio benchmark rules, area-classification-floor area ratio correction rules and track floor area ratio correction rules.

[0073] The commercial and residential ratio allocation rules based on classification are as follows in Table 1:

[0074]

[0075]

[0076] Table 1

[0077] The plot strength of a given area corresponds to the volume ratio benchmark VR base As shown in Table 2:

[0078] Strength Unit Strength <![CDATA[Residential land VR Rbase > <![CDATA[Commercial land VR Bbase > Commercial and residential land Residential and commercial land Low intensity 1.2 1.5 1.38 1.32 Low to medium intensity 1.5 2 1.8 1.7 Moderate 2 2.5 2.3 2.2 Medium to high strength 2.5 3 2.8 2.7 High strength 2.5 3.5 3.1 2.9

[0079] Table 2

[0080] The benchmark volume ratios for commercial and residential land and residential / commercial land are derived from the above classification-based allocation rules and the benchmark volume ratios for residential / commercial land. The volume ratio benchmark VR corresponding to the intensity of the plots in a given area base =α r *VR Rbase +α b *VR Bbase .

[0081] The threshold of the area-to-volume ratio correction factor is related to the classification, and the residential area correction factor γ 1RAs shown in Table 3:

[0082] Area S / hectare <![CDATA[Residential - area correction coefficient γ 1R > S≤4 0 4<S≤8 -0.15 S>8 -0.25

[0083] Table 3

[0084] Commercial-Area Correction Factor γ 1B As shown in Table 4:

[0085] Area S / hectare <![CDATA[Commercial - Area correction factor γ 1B > S≤2 0 2<S≤4 -0.10 S>4 -0.20

[0086] Table 4

[0087] Similar to the calculation basis of floor area ratio, the area correction coefficient of commercial and residential land and residential and commercial land is derived by deduction, γ1 = α r *γ 1R +α b *γ 1B ;

[0088] The track volume ratio correction coefficient γ2 is as shown in Table 5:

[0089] Track Type + Range Transfer Station 300 Ordinary station 300 Transfer Station 600 Ordinary station 600 Floor area ratio correction factor +0.5 +0.3 +0.2 +0.1

[0090] Table 5

[0091] The basic data and correction coefficients obtained in the above-mentioned embodiment of the volume ratio correction module 60 can be corrected by matrix operation by setting the allocation ratio of residential land to commercial land to 0 and 1, which can effectively unify the operation form and speed up the operation. The final formula is as follows to obtain the volume ratio VR:

[0092]

[0093] Similarly, the residential building volume ratio VR can be obtained R VR for commercial building volume ratio B :

[0094] VR R =VR Rbase ×(1+γ 1R +γ2);

[0095] VR B =VR Bbase ×(1+γ 1B +γ2);

[0096] The building area calculation module 70 calculates the comprehensive building area, the residential building area and the commercial building area respectively according to the method that the building area is equal to the volume ratio multiplied by the area of ​​the plot in a given area.

[0097] The information storage module 80 mainly stores the building area and volume ratio as the main output of the system, while intermediate data such as area correction, track coverage and correction, and allocation ratio can also be saved to facilitate subsequent research and optimization.

[0098] The efficient urban planning volume ratio automatic correction system of the present invention is mounted on a terminal device and runs, and the terminal device includes: a memory, a processor, a communication bus, and an efficient urban planning volume ratio automatic correction program stored in the memory:

[0099] The communication bus is used to realize the connection and communication between the processor and the memory;

[0100] The processor is used to execute the efficient urban planning floor area ratio automatic correction program to implement the steps of the above-mentioned efficient urban planning floor area ratio automatic correction method.

[0101] In addition, an embodiment of the present invention may also propose a computer-readable storage medium, which is applied to a computer. The computer-readable storage medium may be a non-volatile computer-readable storage medium. A high-efficiency urban planning floor area ratio automatic correction program is stored on the computer-readable storage medium. When the high-efficiency urban planning floor area ratio automatic correction program is executed by a processor, the steps of the high-efficiency urban planning floor area ratio automatic correction method as described above are implemented.

[0102] Among them, the steps implemented when the efficient urban planning floor area ratio automatic correction program running on the processor is executed can refer to the embodiment of the efficient urban planning floor area ratio automatic correction method in the present invention, and will not be repeated here.
