Description

Technical Field

[0001] The present invention specifically relates to a method for evaluating land use layout based on the adjacent relationship between work and residence land. Background Art

[0002] Work-residence land usually refers to land for accommodating workplaces (work) and land for accommodating residences (residence). The former includes administrative and industrial land, which are collectively referred to as industrial land in this paper, and the latter is called residential land. They are the main places where commuting traffic occurs. Commuting mainly refers to commuting to and from get off work, and the range of movement forms a commuting circle. The land layout with a short commuting distance within the commuting circle is a reasonable layout.

[0003] At present, the rationality of land use layout is generally measured by the ratio of the number of jobs in the commuting circle to the number of industrial population among residents. The more balanced the work and residence, the shorter the commuting distance. This method of job-residence ratio requires the collection of the number of jobs and the number of residents, and can provide an assessment for the balanced layout of job-residence land. It is more convenient than the method of evaluating land layout by considering commuting time. However, the former method cannot judge the layout adjustment of job-residence land, that is, the layout change of job-residence land in the commuting circle will not change the job-residence ratio relationship, while the latter relies on the transportation system to offset some of the effects of spatial distance, but also conceals the basic spatial distance relationship between some land uses, and requires the collection and calculation of a large amount of transportation network data, which is relatively complex and time-consuming to operate. Therefore, when there are more optional land planning schemes, both methods are unable to provide a better basis for land layout decisions to shorten commuting distances in a timely manner.

[0004] Therefore, there is an urgent need to design a rapid assessment method for the layout of employment and residential land to at least partially alleviate or even eliminate the above-mentioned shortcomings and defects of existing methods. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defect that the prior art lacks a land layout plan that can quickly evaluate the commuting distance, especially the defect that the prior art lacks a solution that can provide an effective evaluation of the layout of work-residence land without relying on a large amount of additional data collection, especially user data collection, and proposes a new land layout evaluation method based on the adjacent relationship between work-residence land.

[0006] It is understandable that the present disclosure is based on the following basic concept, that is, the longer the adjacent boundaries of the various land uses within the commuting circle and the smaller the area, the shorter the distance between them and the more reasonable the layout. Therefore, if an evaluation method for evaluating the layout of land uses can be constructed in an appropriate manner from this perspective, a more objective, quantifiable and comparable evaluation of the layout of land uses can be performed without relying on a large amount of additional data collection, especially user data collection.

[0007] The present invention solves the above technical problems by adopting the following technical solutions:

[0008] The present invention provides a flow schematic diagram of an evaluation method for land use layout based on the adjacent relationship between employment and residential land. The evaluation method takes into account the target area to be studied and the corresponding map containing traffic network information and land use information, and evaluates the spatial adjacent relationship of land use based on the map. The evaluation method includes the following steps:

[0009] Step 1: According to the target area on the map, delimit the scope of the commuting circle, and determine the three types of land use with different attributes included therein, namely industrial land, residential land, and mixed land. Then, respectively delimit the boundaries of the contiguous industrial land, residential land, and mixed land within the commuting circle. The mixed land refers to the land where the spaces containing industrial and residential uses overlap or are fragmented, such as a commercial and residential area with a mixture of business and residence;

[0010] Step 2: Number the land use with delimited boundaries according to the land use attributes. Among them, the industrial land is numbered as j, j ∈ N m , N m is the total number, the residential land is numbered as i, i ∈ N r , N r is the total number, and the mixed land is numbered as k, k ∈ N x , N x is the total number, where the superscripts r, m, and x respectively represent the meanings of residence, industry, and mixture;

[0011] Step 3: Calculate the areas of each residential land industrial land and mixed land

[0012] Step 4: Calculate the lengths of the adjacent boundaries between the residential land, industrial land, and mixed land respectively. The adjacent boundary is defined as that the adjacent distance between the boundaries of different attribute lands is within a preset threshold distance and there is a traffic corridor passing between the lands. Among them is the length of the adjacent boundary between a single residential land i and the surrounding lands, is the length of the adjacent boundary between a single industrial land j and the surrounding lands, is the length of the adjacent boundary between a single mixed land k and the surrounding lands;

[0013] Step 5: Use the following formulas (4)-(6) to calculate the layout index of a single land use. Among them, formulas (4)-(6) respectively correspond to the calculation of the layout indexes of residential land, industrial land, and mixed land. Among them

[0014]

[0015] In formula (4), is the layout index of residential land i, is the adjacent boundary length of residential land i, is the area of residential land i;

[0016]

[0017] In formula (5), is the layout index of industrial land j, is the adjacent boundary length of industrial land j, is the area of industrial land j;

[0018]

[0019] In formula (6), is the layout index of mixed land k, is the adjacent boundary length of mixed land k, is the area of mixed land k, and P k is the boundary perimeter of mixed land k.

[0020] Step Six: Repeat Step Four and Step Five to traverse all residential lands, industrial lands, and mixed lands, and obtain the layout indices of each residential land, industrial land, and mixed land respectively i ∈ N r , j ∈ N m and k ∈ N x (Here, by comparing the layout indices of individual lands with each attribute, the spatial layout of the lands can be studied to find ways to optimize the layout);

[0021] Step Seven: Summarize the calculation results of Step Six to calculate the overall layout index of each type of land (i.e., land with each attribute), and the overall layout index is used to indicate the degree of layout optimization required for each type of land within the commuting circle of the target area.

[0022] In the above embodiment, the boundary perimeter P of the mixed land k can be the adjacent boundary length because it is considered that the mixed land can be regarded as overlapping industrial land and residential land. Therefore, its land boundary becomes the adjacent boundary shared by the two types of land with different attributes, and the perimeters of the two lands are the lengths of the adjacent boundary. For this consideration, in formula (6) above, the adjacent boundary length of the mixed land needs to be additionally added with twice the perimeter of its own land boundary.

[0023] The evaluation of the layout index of land in the above implementation is based on the following concept, that is, the longer the length of the adjacent boundaries between residential land, industrial land and mixed land, and the smaller the land area, the shorter the commuting distance between them will be, which means that the layout position is better. In addition, based on the evaluation of the above implementation, the overall layout index of each type of land can be evaluated at the level of land attributes. For example, it may be indicated that the layout index of a certain attribute is relatively low, and therefore it is relatively in the greatest need of improvement and optimization, thereby providing directional guidance for land layout optimization.

[0024] According to some preferred embodiments of the present invention, when dividing the boundary in step 1, when encountering adjacent boundaries of land uses with the same attributes, the corresponding boundaries are cancelled to make the land uses with the same attributes as connected as possible and form a new closed boundary.

[0025] It is understandable that this way of dividing boundaries is, on the one hand, closer to the requirements of evaluating the degree of land optimization in reality, and on the other hand, it minimizes the number of divided land pieces and boundary lengths, thereby significantly reducing the complexity of the calculation process while ensuring the accuracy and objectivity of the subsequent calculation and evaluation process, and improving the efficiency of the evaluation method.

[0026] According to some embodiments of the present invention, step 4 comprises:

[0027] For residential land, measure and record the length of the adjacent boundaries between each single residential land i in the map and the surrounding industrial land and mixed land and Based on the recorded data, the length of the adjacent boundary between a single residential land i and the surrounding land is calculated using the following formula (1):

[0028]

[0029] in,

[0030]

[0031] And among them, is the adjacent correlation coefficient between residential land i and industrial land j, is the adjacent correlation coefficient between residential land i and mixed land k;

[0032] For industrial land, measure and record the length of the adjacent boundaries between each single industrial land j in the map and the surrounding residential land and mixed land and Based on the recorded data, the length of the adjacent boundary between a single industrial site j and the surrounding sites is calculated using the following formula (2):

[0033]

[0034] Among them,

[0035]

[0036] And among them, is the adjacent correlation coefficient between industrial land j and residential land i, is the adjacent correlation coefficient between industrial land j and mixed land k;

[0037] For mixed land, measure and record the adjacent boundary lengths between each individual mixed land k in the map and the surrounding residential and industrial lands and And calculate the length of the adjacent boundary between the individual mixed land k and the surrounding lands using the following formula (3) based on the recorded data,

[0038]

[0039] Where

[0040]

[0041] And among them, is the adjacent correlation coefficient between mixed land k and residential land i, is the adjacent correlation coefficient between mixed land k and industrial land j.

[0042] Among them, the default value of the threshold distance can be set to 300 meters, which is a distance generally considered convenient for walking.

[0043] According to some embodiments of the present invention, step seven includes calculating the overall layout index of each of the three types of land, namely residential land, industrial land, and mixed land, using the following formulas (7)-(9). Among them, the overall layout index for residential land is calculated using the following formula (7),

[0044]

[0045] In formula (7), the overall layout index of residential land is the ratio of the total adjacent boundary length of residential land to the total area of residential land;

[0046] The overall layout index of industrial land is calculated using the following formula (8),

[0047]

[0048] In formula (8), the overall layout index of industrial land is the ratio of the total adjacent boundary length of industrial land to the total area of industrial land;

[0049] The overall layout index of the mixed land use is calculated using the following formula (9):

[0050]

[0051] In formula (9), P k is the perimeter of the mixed land use k, and the overall layout index of the mixed land use is the ratio of the total adjacent boundary length of the mixed land use to the total area of the mixed land use.

[0052] According to some embodiments of the present invention, the evaluation method further includes the following steps executed after the seventh step:

[0053] Step eight, calculate the comprehensive layout index of the total land use within the commuting circle of the target area using the following formula (10). The comprehensive layout index is applicable to indicating the rationality and the degree of optimization required for the layout of the total land use in the target area, where

[0054]

[0055] wherein, the comprehensive layout index D of the total land use is calculated by integrating the adjacent boundary length and the land area of each type of land use.

[0056] Based on common knowledge in the art, the above preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0057] The positive and progressive effects of the present invention are as follows:

[0058] According to the evaluation method for land use layout based on the adjacent relationship between employment and residence land of the present invention, it is possible to provide an effective evaluation of the employment and residence land layout without relying on a large amount of additional data collection, especially user data collection, and has the advantages of fast evaluation speed, high efficiency, quantifiability, and comparability.

[0059] Furthermore, by comparing the levels of the layout indices, multi - scheme comparison and selection of land use planning can be carried out, a better scheme can be selected from them for in - depth study, and it can also be used for re - evaluation after the optimization of the planning scheme.

[0063] The method of the following preferred embodiments of the present invention is generally based on the following technical concept: for each land use within the commuting circle, the longer the adjacent boundary and the smaller the area, the shorter the connection distance between them, and the more reasonable the layout. Therefore, if an evaluation method for land use layout can be constructed in an appropriate manner from this perspective, it is possible to conduct a relatively objective, quantifiable, and comparable evaluation of land use layout without relying on a large amount of additional data collection, especially user data collection.

[0064] Figure 1 A schematic flow chart of an evaluation method for land use layout based on the adjacent relationship of employment and housing land according to a preferred embodiment of the present invention is schematically shown. The evaluation method takes into account the target area to be studied and the corresponding map containing traffic network information and land use information, and evaluates the spatial adjacent relationship of land use based on the map. The evaluation method includes the following steps:

[0065] Step 1: On the map, delimit the scope of the commuting circle according to the target area, and determine the three types of land use with the following attributes, namely industrial land, residential land, and mixed land. Then, respectively delimit the boundaries of the contiguous industrial land, residential land, and mixed land within the commuting circle;

[0066] Step 2: Number the land use with delimited boundaries according to the land use attributes. Among them, the industrial land is numbered as j, j ∈ N m , N m is the total number, the residential land is numbered as i, i ∈ N r , N r is the total number, and the mixed land is numbered as k, k ∈ N x , N x is the total number, where the superscripts r, m, and x respectively represent the meanings of residential, industrial, and mixed;

[0067] Step 3: Calculate the area of each residential land the area of industrial land and the area of mixed land

[0068] Step 4: Calculate the lengths of the adjacent boundaries among residential land, industrial land, and mixed land respectively. The adjacent boundary is defined as the boundary between different types of land where the adjacent distance is within a preset threshold distance and there is a transportation corridor passing through. Among them, is the length of the adjacent boundary between a single residential land i and its surrounding land, is the length of the adjacent boundary between a single industrial land j and its surrounding land, is the length of the adjacent boundary between a single mixed land k and its surrounding land;

[0069] Step 5: Calculate the layout index of a single piece of land using the following formulas (4)-(6). Among them, formulas (4)-(6) correspond to the calculation of the layout index of residential land, industrial land, and mixed land respectively. Among them,

[0070]

[0071] In formula (4), is the layout index of residential land i, is the length of the adjacent boundary of residential land i, is the area of residential land i;

[0072]

[0073] In formula (5), is the layout index of industrial land j, is the length of the adjacent boundary of industrial land j, is the area of industrial land j;

[0074]

[0075] In formula (6), is the layout index of mixed land k, is the length of the adjacent boundary of mixed land k, is the area of mixed land k, P k is the perimeter of the boundary of mixed land k.

[0076] Step 6: Repeat Step 4 and Step 5 to traverse all residential lands, industrial lands, and mixed lands, and obtain the layout indices of each residential land, industrial land, and mixed land respectively i ∈ N r 、 j ∈ N m and k ∈ N x (Here, by comparing the layout indices of individual lands of each attribute, the spatial layout of the land can be studied to find ways to optimize the layout);

[0078] In the above embodiment, the boundary perimeter P of the mixed land k The reason why it can be the adjacent boundary length is that mixed-use land can be regarded as overlapping industrial land and residential land, so its land boundary becomes the adjacent boundary shared by the two types of land, and the perimeter of each of the two lands is the length of the adjacent boundary. For this reason, the adjacent boundary length of the mixed-use land in the above formula (6) needs to be doubled by the perimeter of its own land boundary.

In addition, based on the evaluation of the above implementation, the overall layout index of each type of land can be evaluated at the level of land attributes. For example, it may be indicated that the layout index of a certain attribute is relatively low, and therefore it is relatively in the greatest need of improvement and optimization, thereby providing directional guidance for land layout optimization.

[0080] According to some preferred embodiments of the present invention, when dividing the boundary in step 1, when encountering adjacent boundaries of land uses with the same attributes, the corresponding boundaries are cancelled to make the land uses with the same attributes as connected as possible and form a new closed boundary.
