Background
The volume ratio refers to the ratio of the total building area to the building land area in a certain block. The volume ratio reflects development intensity and is an index of frequent research in the field of urban planning. In the planning process of the volume ratio of a single plot, a plurality of factors such as the position of the plot, the influence of natural landform and landform, the size of the plot, the supporting condition of peripheral public transportation, population, the land property of the plot and the like need to be comprehensively considered; the plot ratio planning on the whole city scale also needs to consider the problems of the whole city population scale, the city development total amount and the like for macroscopic overall consideration. In the implementation process of the above research, analysis of big data calculation is needed, and in the traditional city planning process, planning practitioners generally use AutoCAD and PhotoShop tools, so that the plot volume ratio of a certain area is often directly set based on the plot position and the planning overall arrangement.

However, a single calculation flow using the ArcGis tool takes a long time, and because each link of the ArcGis tool needs to call different calculation processes of the ArcGis, and an intermediate calculation result needs to be manually screened or script-processed and then subsequently called, the whole corrected volume fraction calculation process is very time-consuming, a planning practitioner skilled in using the ArcGis tool still needs to take 3-5 working days, and too much manual participation in calculation easily causes calculation omission and errors.

In practical application, referring to fig. 2, the efficient urban planning volume rate automatic correction system includes:
the data import module 10 imports a given area block, an intensity unit and a track influence range file;
the preprocessing module 20 is used for standardizing each field of the given area block, the intensity unit and the track influence range file imported by the data import module 10 to obtain standardized space and attribute data;

and the volume ratio correction module 60 corrects the volume ratio according to the reference volume ratio, the single volume ratio correction coefficients, the commercial scale coefficient and the orbit correction coefficient, and calculates the comprehensive volume ratio, the commercial volume ratio and the living volume ratio of the plot in the given area.
In one embodiment, the efficient city planning volume rate automatic correction system is realized in the form of ArcGis plug-in, and the plug-in is packaged into the format of an ArcGis toolbox tbx, and the format file can be directly added into a program on a computer provided with ArcGis software and appears in a system toolbox after being added. The plug-in is made by an ArcGis official tool, and the use threshold of the system is reduced by combining a Python script for realizing the system function with a visual input and output interface.
In this embodiment, the given area block and the strength unit imported by the data import module 10 are connected in a spatial connection manner, that is, the given area block and the strength unit are connected in a spatial relationship corresponding to an actual geographic area position, so that the efficiency of processing the spatial relationship by the system is greatly improved compared with the connection in an intersection relationship.
Referring to fig. 2, eight modules, namely, a data importing module 10, a preprocessing module 20, a spatial relationship processing module 30, a track correction module 40, a rule engine module 50, a volume ratio correction module 60, a building area calculation module 70 and an information storage module 80, are provided, wherein only the data importing module 10 needs user operation, and the user operation is facilitated by selecting a required region block, a required intensity unit and track data by a planning practitioner and selecting a cache file directory as a storage location for some intermediate results in the process. And after the selection is finished, clicking to determine, and then starting the operation.
It should be noted that the strength unit in the present scheme is to divide the central city area into a plurality of strength unit areas, for example, taking the central city area of Chongqing as an example, the central city area is divided into 5 strength levels, specifically, a first strength unit area, a second strength unit area, a third strength unit area, a fourth strength unit area and a fifth strength unit area, where the first strength unit area and the second strength unit area are mainly a core area of four banks in two rivers, a traditional business circle and a peripheral area, a cluster center and a peripheral area, a comprehensive transportation hub and a peripheral area, an important rail transportation node and a peripheral area; the five areas of the intensity unit are mainly areas of 'four banks in two rivers' outside the inner ring, the periphery of the mountain body in an important city, 'four mountains' and the peripheral areas thereof, traditional landscape areas, historical culture blocks and the peripheral areas; the three areas of the intensity unit and the four areas of the intensity unit are other areas of the city. The reference volume fractions and the volume fraction control ranges of residential and commercial sites in the plurality of intensity unit areas are set according to actual conditions, for example, in the present scheme, the reference volume fraction of the intensity unit area may be 2.5; the reference volume ratio of the second area of the intensity unit can be 2.5, and the volume ratio can be controlled to be below 3.75; the reference volume ratio of the three areas of the intensity unit can be 2.0, and the volume ratio can be controlled to be below 3.0; the reference volume ratio of the four areas of the intensity unit can be 1.5, and the volume ratio can be controlled to be below 1.2; the reference volume ratio of the five regions of the intensity unit can be 2.5, and the volume ratio can be controlled to be below 1.8.
In one embodiment, referring to fig. 3, the preprocessing module 20 normalizes fields of the given region block, intensity unit and track influence range file imported by the data import module 10 to obtain normalized space and attribute data, specifically, normalized space and attribute data
(1) Data normalization, as in the case of the area used in hectare based on the area correction volumetric rate rules, requires a conversion of the unit area of a given area plot.
(2) And adding band operation fields involved in the subsequent calculation process, wherein the fields comprise an output field required by the output of the final result and a process field required in the processing process.
(3) Encoding the non-numeric field for subsequent calculation, wherein the encoding of the non-numeric field comprises three parts, one is to encode the strength into an integer from a character string form such as a high-strength area; secondly, the city construction land classification name is coded, the value of the field is complex, the selectable value in the test data is more, 7860 types are not beneficial to subsequent calculation, and therefore the field is recoded into four types of land for residence, commercial land, land for residential business and land for business and residence based on the basic format of the field value characteristic (business) (residence), and the four types of land for business and residence are respectively mapped into positive integers; and thirdly, coding of the track coverage range, wherein a common station and a transfer station are distinguished from the track station, the track influence range is gradually attenuated along with the distance, the attenuation rate is difficult to measure and calculate through accurate calculation, and the calculation amount is greatly increased during subsequent volume rate correction, so that the scheme selects the interval normalization, the 300-meter range is the core range influenced by the station, the 600-meter range is influenced to a certain extent, and the range exceeding 600 meters is not influenced.
In one embodiment, the spatial relationship calculation module mainly calculates two spatial relationships:
(1) the method comprises the steps of giving a spatial relationship between a region plot and an intensity unit, and judging which intensity unit the given region plot is contained in, wherein the time consumption is long because generally more plots and intensity units are contained in the given region plot, and assigning the intensity of the intensity unit to the given region plot according to an intersection result after intersection is adopted; therefore, the scheme directly assigns the strength of the strength unit to the associated given area land block according to the relative position of the space by utilizing the space connection in the ArcGis tool. In addition, for plots spanning multiple intensity units, the mass center of the plot is adopted as the standard for judging the intersection with the intensity units in the process of spatial connection, so that the randomness of intersection judgment can be effectively avoided.
(2) Given the spatial relationship between the region plot and the track, since the influence ranges of the track are defined as two ranges of 300 meters and 600 meters in the above embodiment, the two influence ranges of the given region plot and the track are respectively connected spatially, and finally, the codes of the influence ranges and the track types are assigned to the intersecting plots.
In an embodiment, referring to fig. 2, the efficient urban planning volume rate automatic correction system further includes an orbit correction module: the system adopts the method that the area influence is used for taking the maximum value, the set distance of the influence factors is greater than the type, the 300 meters of the transfer station in the influence factors are greater than the 300 meters of the common station, the 300 meters of the common station are greater than the 600 meters of the transfer station, the 600 meters of the transfer station are greater than the 600 meters of the common station, and finally, the influence of different types of tracks covered in different ranges is converted into a single factor problem, and the cross correlation value is given to the plot in the given area.
In one embodiment, referring to FIG. 4, the rules engine module 50 generally includes class-based quotient allocation rules, as well as intensity-volume rate benchmark rules, area-class-volume rate modification rules, and orbit volume rate modification rules.
The classification-based quotient and survival allocation rule is as follows in table 1:
