Description

Technical Field

[0001] This invention belongs to the field of land use planning technology, and in particular relates to an automatic layout method, electronic device and storage medium for commercial land based on planning indicators. Background Technology

[0002] Commercial land planning and design is the process by which planners design the spatial layout of commercial land based on established indicators from higher-level plans and the main types of commercial activities on the land.

[0003] The main indicators set forth in the higher-level planning are as follows: ① Floor area ratio (FAR), FAR = Total building area / Land area; ② Building height limit; ③ Building density, Building density = Building site area / Building land area. These indicators are mandatory, and designers must not exceed their upper or lower limits during the planning process. Therefore, as the building layout is continuously modified and optimized during the design phase, these planning indicators need to be repeatedly calculated.

[0004] With the development of modern cities, commercial land has gradually formed various spatial layouts to adapt to different types of commercial activities. These can be roughly divided into several categories, such as integrated, street-style, homogeneous, and mixed. Planning designers will choose the spatial layout based on the main types of commercial activities on the site. After determining the layout, they will design the road network framework, building unit combinations, greening design, and other aspects, ultimately completing the architectural layout of commercial land in urban planning.

[0005] The above are the main design influencing factors for commercial land planning and design. On the one hand, it is necessary to meet the spatial layout design of various commercial activities as much as possible. On the other hand, it is also necessary to comply with the compliance requirements of the design indicators. Finally, the plan is determined through continuous iteration and optimization.

[0006] The current layout of commercial land use faces the following technical challenges:

[0007] (1) The layout of commercial land buildings on a large spatial scale involves a large workload and is time-consuming. Commercial land is one of the most common land uses in urban planning and design. In urban-scale development and urban design, commercial land is distributed in patches, and the design scale is large. Moreover, the depth of architectural spatial layout in the urban design stage is not as great as that in architectural scheme design. The planning and design at this stage only focuses on highlighting spatial structure, spatial texture, and intensity control. Therefore, designers will make schematic representations based on the layout rules of commercial land. When the design scale is too large and many similar plots repeatedly repeat the same layout, this design mode becomes relatively cumbersome and inefficient.

[0008] (2) Mismatch between rigid control indicators and flexible spatial form guidance. Due to limitations in calculation accuracy and efficiency, planners cannot precisely combine different building volumes within a plot of land in one go during the architectural spatial layout process. In most cases, they can only roughly determine the corresponding building type based on design experience and the plot ratio. For example, a plot ratio of 2.8 to 4.5 is mainly for high-rise buildings, while a plot ratio of 1.0 to 2.0 is mainly for multi-story buildings. However, a more precise combination of building volumes corresponding to the plot ratio needs to be determined by calculation. The precise correspondence between control indicators and flexible spatial forms requires repeated verification and refinement. In projects with tight deadlines or excessive scale, designers often choose to relax the precision and pursue more visual effects, resulting in significant discrepancies between spatial form and control indicators, leading to resource waste and decision-making errors. Summary of the Invention

[0009] The purpose of this invention is to provide an automatic layout method, electronic device and storage medium for commercial land, so as to solve the problems of large workload, high time consumption and mismatch between rigid control indicators and flexible spatial form guidance content in the existing commercial land layout.

[0010] This invention solves the above-mentioned technical problems through the following technical solution: an automatic layout method for commercial land based on planning indicators, comprising the following steps:

[0011] Obtain commercial land use documents and determine the setback distance of the commercial land use based on the width of the roads surrounding the commercial land use and the building height limit within the commercial land use;

[0012] The commercial land after the setback is divided into multiple primary sub-plots;

[0013] The outer contour of the podium building is set back d meters from the outline of each of the first-level sub-plots. The podium building is then shifted inward by b meters based on the outer contour of the podium building to form its depth.

[0014] With the apex of the podium building as the apex, towers are arranged along the short side of the podium building, and the outline of the towers does not exceed the outer outline of the podium building;

[0015] Each of the first-level sub-plots is divided into multiple second-level sub-plots;

[0016] The building footprint area and the total standard floor area of ​​the tower are calculated.

[0017] The building height of the podium is determined based on the commercial land area, plot ratio, building footprint area, and maximum floor limit.

[0018] The building height of the tower is determined based on the commercial land area, plot ratio, building footprint area, number of floors in the podium, and the total standard floor area of ​​the tower.

[0019] Furthermore, when the road width is ≤24m and the building height limit is <24m, the setback distance is 3m;

[0020] When the road width is ≤24m and 24m≤building height limit<60m, the setback distance is 8m;

[0021] When the road width is ≤24m and the building height limit is 60m≤building height<100m, the setback distance is 10m;

[0022] When the road width is ≤24m and the building height limit is 100m, the setback distance is 15m.

[0023] When the road width is greater than 24m and the building height limit is less than 24m, the setback distance is 5m.

[0024] When the road width is greater than 24m and 24m ≤ building height limit < 60m, the setback distance is 10m;

[0025] When the road width is greater than 24m and the building height limit is 60m ≤ building height < 100m, the setback distance is 15m;

[0026] When the road width is greater than 24m and the building height limit is 100m or less, the setback distance is 20m.

[0027] Furthermore, the specific process for dividing the setbacked commercial land is as follows:

[0028] Using the point (not the endpoint) on the longest side of the commercial land after setback as the dividing point, and the direction perpendicular to the longest side as the dividing direction, the commercial land is divided so that the area of ​​the first-level sub-plots after division is less than a first set threshold.

[0029] When the area of ​​the remaining plot is greater than or equal to the first set threshold, the remaining plot is divided by taking the point (not the endpoint) on the longest side of the remaining plot as the dividing point and the direction perpendicular to the longest side as the dividing direction, so that the area of ​​the first-level sub-plots after the division is less than the first set threshold.

[0030] This process continues until the area of ​​all first-level sub-plots is less than the first set threshold, resulting in multiple first-level sub-plots.

[0031] Preferably, the longest side is divided into 10 equal parts, and the two endpoints of the longest side are set as the first and eleventh division points, respectively, with any point between the fourth and eighth division points as the dividing point.

[0032] Preferably, when dividing commercial land or remaining land parcels, the dividing line is 8m wide, and the dividing line serves as the main road within the parcel.

[0033] Furthermore, when the area of ​​the remaining plot is less than the second set threshold, the remaining plot is designated as green space, wherein the second set threshold is less than the first set threshold.

[0034] Furthermore, the specific implementation process for dividing each of the aforementioned first-level sub-plots is as follows:

[0035] Using the point (not the endpoint) on the longest side of the first-level sub-plot as the dividing point, and the direction perpendicular to the longest side as the dividing direction, the first-level sub-plot is divided so that the area of ​​the divided second-level sub-plot is less than a third set threshold; wherein, the second set threshold < the third set threshold < the first set threshold.

[0036] When the area of ​​the remaining plot is greater than or equal to the third set threshold, the remaining plot is divided with the point (not the endpoint) on the longest side of the remaining plot as the dividing point and the direction perpendicular to the longest side as the dividing direction, so that the area of ​​the divided second-level sub-plots is less than the third set threshold.

[0037] This process continues until the area of ​​all secondary sub-plots is less than the third set threshold, resulting in multiple secondary sub-plots.

[0038] Preferably, when dividing the primary sub-plots, the dividing line is 8m wide, and the dividing line serves as a secondary road within the primary sub-plot.

[0039] Furthermore, when the dividing line touches a tower and the area of ​​the remaining plot after the division is less than the fourth set threshold, the setting of the corresponding tower is cancelled, wherein the fourth set threshold is less than the second set threshold.

[0040] Furthermore, the specific process for determining the building height of the podium is as follows:

[0041] The total proposed building area is calculated based on the commercial land area and plot ratio.

[0042] The number of podium floors will be determined based on the total planned building area, building footprint area, and maximum floor limit.

[0043] Calculate the building height of the podium based on its floor height and number of floors.

[0044] Furthermore, the specific process for determining the building height of the tower is as follows:

[0045] The total proposed building area is calculated based on the commercial land area and plot ratio.

[0046] The remaining total building area is calculated based on the proposed total building area, the building footprint area, and the number of podium floors.

[0047] Calculate the number of floors in the tower based on the remaining total building area and the total standard floor area of ​​the tower.

[0048] The building height of the tower is calculated based on the number of floors and the floor height.

[0049] The present invention also provides an electronic device, comprising: a memory for storing a computer program; and a processor for executing the computer program to implement the steps of the automatic layout method for commercial land based on planning indicators as described above.

[0050] The present invention also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the automatic layout method for commercial land based on planning indicators as described above.

[0051] Beneficial effects

[0052] Compared with the prior art, the advantages of the present invention are as follows:

[0053] The present invention provides an automatic layout method, electronic device and storage medium for commercial land. The layout method follows the mainstream commercial layout pattern to divide the land space and selects the combination form of commercial complex, namely the combination pattern of podium + tower, to generate a typical commercial land layout.

[0054] This method can provide planners with intuitive spatial form references during the urban design phase of commercial land, and greatly improve design efficiency and accuracy. The method is driven by index parameters to generate buildings, so the total building area, building height and other parameters of the scheme are fully compliant with the specified plot ratio, building height limit and other planning indicators, which greatly reduces the workload of architects to repeatedly verify and solves the problem of inaccurate estimation based on experience in traditional design.

[0069] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0070] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0071] Example 1

[0072] like Figure 1 As shown in the figure, an automatic layout method for commercial land based on planning indicators provided by an embodiment of the present invention includes the following steps:

[0073] Step 1: Obtain commercial land documents and determine the commercial land setback based on the width or grade of the roads surrounding the commercial land and the building height within the commercial land.

[0074] In this embodiment, the setback distance is calculated based on information such as the plot area, plot outline, surrounding roads, and building height limits in the commercial land use documents, as shown in Table 1.

[0075] Table 1. Relationship between road width, building height limit, and setback distance.

[0076]

[0077] Considering that commercial buildings within commercial land are generally large in scale, towers are mainly high-rise buildings, and most commercial centers also include commercial plazas, a default setback of 20 meters can be set for quick layout generation. Figure 2 As shown.

[0078] Step Two: Perform primary subdivision or division of the commercial land after setback.

[0079] When the land area is too large, it needs to be subdivided into tiered plots. Based on conventional urban models, the subdivision principles are as follows:

[0080] ① Primary Division: The maximum area threshold for each primary sub-plot is set at 30,000 square meters. This first threshold is 30,000 square meters. The plots are then divided to obtain primary sub-plots, which are each commercial complex plot. For example... Figure 3 As shown;

[0081] ② Dividing point location: Divide the longest side of each polygon (plot or remaining plot) into 10 equal parts. Let the two endpoints of the longest side be the 1st and 11th division points, respectively. The intermediate division points are numbered sequentially. Any point between the 4th and 8th division points (this point does not necessarily have to be a division point; any point between the 4th and 8th division points is acceptable) is used as the dividing point to ensure that the dividing point is not too close to the extreme positions of the edge vertices.

[0082] ③ Cutting direction: Perpendicular to the longest side;

[0083] ④ The dividing line between the plots can be used as a traffic road (main road) within the plot, with a width of 8 meters;

[0084] ⑤ Remaining plots: If the area of ​​the remaining plots after the division is less than 500m² 2 That is, the second set threshold is set to 500m 2 Then it is designated as green space.

[0085] Because the land parcels are divided using a random ratio, the results of each execution of the method of this invention will differ for each commercial land parcel, increasing the diversity of the forced sorting algorithm.

[0086] Step 3: Generate the podium building

[0087] Driven by commercial interests, commercial buildings tend to maximize their street-facing space. Therefore, the outer outline of the podium is set back 14 meters (d = 14 meters) from the outline of each primary sub-plot to ensure maximum street-facing space. The podium is then offset inwards from this outer outline by a distance b, which represents the depth of the podium. Figure 4 As shown. In this embodiment, the offset distance b is randomly selected from the given data set, ensuring the flexibility of the scheme. The offset distance data set consists of three values: 24m, 32m, and 40m. This data set is derived from the column grid system of mainstream high-rise buildings: taking an 8.1-meter column grid system, 3 spans, 4 spans, and 5 spans are selected respectively, meaning that the offset distance is arbitrarily selected from this data set.

[0088] It is important to note that for irregularly shaped land parcels, some may contain sharp corners after the land is divided. Generating a podium building based on this first-level sub-parcel will result in acute-angled volumes, which does not conform to conventional architectural design principles. Therefore, the sharp corners of the podium building must be trimmed to maintain its squareness. The trimmed sharp corners will be used as green space. Figure 5 As shown.

[0089] Step 4: Generate the tower

[0090] The tower is generated on the foundation of the podium, and the generated tower satisfies the following conditions:

[0091] ① Length-to-width ratio limit: As a high-rise building, the tower's shape coefficient should not be too large according to seismic requirements. Therefore, the tower adopts a random combination of data sets with a limited number of spans. The data sets are 24 meters, 32 meters, and 40 meters, which correspond to 3, 4, and 5 spans of an 8.1-meter column grid, respectively.

[0092] ② Tower generation location: The tower is placed along the short side of the podium, its apex coincides with the apex of the podium, and the tower's outline must not exceed the podium's outline, such as... Figure 6 As shown;

[0093] ③ In cases of irregular land use, after the tower is generated, cut along the outer edge of the podium to ensure the neatness of the urban building facades along the road, such as... Figure 7 As shown;

[0094] ④ The entire central area enclosed by the building is green space.

[0095] Step 5: Perform secondary subdivision of the primary sub-plots.

[0096] Based on the first-level sub-plots divided in step two, each commercial complex (i.e., the first-level sub-plot) is further divided according to the second-level area threshold. In this embodiment, the third threshold is set at 10,000 square meters, and the specific division principle is as follows:

[0097] ① Maximum area threshold: The default maximum area threshold for the sub-plots after division is 10,000 square meters; it should be noted that the secondary division includes the buildings.

[0098] ② Divide the location: Divide the longest side of the first-level sub-plot into 10 equal parts, and use any point between the 4th and 8th division points of the longest side as the dividing point, ensuring that the dividing point is not too close to the extreme position of the edge vertex.

[0099] ③ Dividing direction: Perpendicular to the longest side;

[0100] ④ The dividing line between the plots can be used as a traffic road within the plots, with a width of 8 meters;

[0101] ⑤ If the division involves towers and the remaining land area after division is less than 200 square meters (i.e., the fourth threshold is 200 square meters), then that part of the towers will be cancelled.

[0102] ⑥ After completion, calculate the building footprint area and the total standard floor area of ​​the tower within the site.

[0103] Step Six: Determine the building height

[0104] The building height of the podium and tower is calculated according to the following principles:

[0105] ① The tower and podium buildings have a uniform floor height of 3.9 meters;

[0106] ②The podium and tower are generated one floor at a time according to the floor area ratio requirements. However, the podium has a maximum of 5 floors. Once the podium reaches the maximum floor limit, it will stop generating. The tower will continue to be generated one floor at a time until the floor area ratio limit or building height limit is reached.

[0107] The relationship between building height restrictions and floor area ratio is as follows: while meeting the building height restrictions, the floor area ratio should be maximized as much as possible. That is, the building height restrictions must be met, but the floor area ratio may not be maximized.

[0108] The specific calculation formula is: Total building area = plot ratio * land area, number of building floors = total building area / single-story building area.

[0109] Example 2

[0110] Taking a residential land parcel in China as an example, the automatic layout method for commercial land parcels according to an embodiment of the present invention includes the following steps:

[0111] Step 1: After obtaining the land parcel file, automatically acquire information such as land parcel attributes, land area, outline, and building height limits. In this embodiment, the land area is 126,541 m². 2 Set the setback distance according to the default setting of 20 meters. Figure 8 As shown.

[0112] Step Two: Primary subdivision of the land parcel: in 30,000m... 2 A threshold was set for the first division, and the land was divided perpendicularly to the longest side. The division points were located between the 4th and 8th division points of the longest side, and the dividing line served as the main road, 8 meters wide. Based on the land area, three divisions were performed, in the following order: Figure 9 The numbers shown are displayed.

[0113] Step 3: Set the outline of the podium building back 14 meters from the outline of the divided primary sub-plots. The depth of the podium building is randomly selected from three values: 24m, 32m, and 40m. In this embodiment, the depth of the podium building is 24m. Figure 10 As shown.

[0114] Step 4: Generate the tower.

[0115] The tower's dimensions will be randomly selected from three options: 24m, 32m, and 40m. It will be positioned along the shorter side of the podium, with its apex coinciding with the podium's apex. The tower's outline must not exceed the podium's height; any excess will be removed to ensure a neat street-facing facade. The entire central area will be green space. Figure 11 As shown.

[0116] Step 5: Secondary segmentation

[0117] Each commercial complex (i.e., a primary sub-plot) is divided according to a third predefined threshold (default 10,000 square meters), generating secondary sub-plots and their secondary roads. The primary and secondary roads together constitute the road system of the plot. The division points are any points between the 4th and 8th division points of the longest side, perpendicular to the longest side. The width of the secondary roads is 8 meters. Figure 12 As shown. If the division involves a tower, and the remaining area of ​​the land after the division is less than 200 square meters, then that part of the tower will be cancelled.

[0118] Step Six: Calculate Building Height

[0119] This stage requires the use of two planning indicators: floor area ratio and building height limit. In this example, the floor area ratio is 3.3, the building height limit is 100m, and the uniform floor height is 3.9m.

[0120] ① Calculate the total planned building area. The total planned building area = land area * plot ratio, that is, 126541 * 3.3 = 417585.3 square meters.

[0121] ② Calculate the number of floors in the podium based on the area.

[0122] According to step five, the building footprint area is 39006.9 m². 2 39006.9 * 5 = 195032.5 (m2 ) < 417585.3 (m 2 This far exceeds the requirement of a maximum floor of 5 stories for the podium building. Therefore, the podium building is determined to be 5 stories high, with a building height of 3.9m * 5 = 19.5m.

[0123] ③ Calculate the tower height based on the area.

[0124] The total standard floor area of ​​the tower is 8902.1 m². 2 The remaining area is 417585.3 - 195032.5 = 222552.8 m². 2 Therefore, the number of floors in the tower = the remaining total building area / the total standard floor area of ​​the tower = 25 floors, and the tower height is 25 * 3.9 meters = 97.5 meters.

[0125] ④ Inspect the building height limit indicators and calculate the final floor area ratio.

[0126] The building height limit is 97.5m < 100m, so the plan is valid; the final plot ratio is 3.297, and the final commercial land layout is as follows. Figure 13 As shown.

[0127] The above description only discloses specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or modifications that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
