[0002] With the continuous acceleration of urbanization, urban construction land is gradually becoming saturated, and the contradiction between supply and demand of land resources is becoming increasingly prominent. In this context, scientific and effective project site selection has become an important task in urban planning and management, which is crucial to achieving a balance between economic benefits, social benefits and environmental benefits.

[0003] At present, the site selection of construction projects mostly relies on traditional manual analysis methods, and the site selection process mainly relies on the experience and judgment of the staff. The biggest problem with this method is the low efficiency of data collection, the rough calculation and evaluation of site selection indicators, and the lack of comprehensive information support. Under the circumstance of tight site selection time, it is impossible to conduct sufficient land evaluation and coordination, resulting in insufficient scientificity and accuracy of the site selection process. In addition, due to the subjectivity of manual operation, the site selection results are easily interfered by subjective consciousness, resulting in decision-making deviations.

[0004] In summary, the current construction project site selection has technical problems such as low efficiency in data collection and analysis and lack of scientific land evaluation methods, which leads to insufficient scientificity and accuracy in the site selection process. Summary of the invention

[0015] The embodiments of the present application provide an auxiliary decision-making method and an auxiliary decision-making system for site selection of construction projects in urban planning, thereby solving the technical problems of low efficiency in data collection and analysis for site selection of construction projects, lack of scientific land evaluation methods, and insufficient scientificity and accuracy in the site selection process. The embodiments of the present application achieve the technical effect of significantly improving the work efficiency, scientificity and accuracy of site selection for urban planning and construction projects, and promoting the sustainable development of urban construction.

[0016] Embodiment 1, as Figure 1 As shown, the embodiment of the present application provides an auxiliary decision-making method for site selection of construction projects in urban planning, and the method includes: Step S1: According to the entire chain of site selection work requirements for urban planning and construction projects, a project site selection auxiliary decision-making system is obtained, wherein the project site selection auxiliary decision-making system includes a plot screening unit, a scheme analysis unit, and a consultation and review unit.

[0017] Specifically, the whole chain of site selection requirements for urban planning and construction projects refers to the entire series of demand processes in the site selection process of urban planning and construction projects, from the initial demand proposal, to the operation of each link in the middle, and then to the final site selection decision. First, according to the overall requirements of the whole chain of site selection requirements for urban planning and construction projects, a project site selection auxiliary decision-making system including multiple functional modules such as plot screening, scheme analysis and expert review is constructed to provide a framework for subsequent decision-making analysis. The project site selection auxiliary decision-making system is a comprehensive system for supporting and assisting project site selection decisions. Among them, the plot screening unit is used to preliminarily screen out plots that meet project requirements, such as suitable geographical location and land area that meets the requirements; the scheme analysis unit conducts a more in-depth analysis of the selected plots, considering multiple factors such as existing infrastructure, land ownership, and public service facilities, so as to determine which plot is most suitable; the consultation and review unit compares and deliberates the information of the first two modules, and comprehensively considers opinions and information from all aspects to determine the final project site selection decision plan.

[0018] Step S2: Loading geographic data, which includes land boundaries, planning information, control areas, current status and ownership information.

[0019] Specifically, the boundaries of the plots, that is, the physical boundaries of the plots, can be determined by maps or satellite images to determine the boundaries of the land. Planning information refers to the rules and regulations related to urban construction and land use planning, which can be extracted from the urban planning database, such as which plots can be used for residential construction and which are used for commercial or industrial purposes. Control areas refer to specific planning restriction areas, such as environmental protection areas, historical sites protection areas, etc., which are usually not suitable for large-scale development. The current situation is a description of the current status of the plot, such as whether it has been developed, whether there are existing buildings, transportation facilities, etc. Ownership information refers to information about the ownership of the plot, which needs to be obtained through the ownership registration system of the land management department to ensure the legality and availability of the plot. Loading geographic data including plot boundaries, planning information, control areas, current situation and ownership information provides comprehensive data support for subsequent plot screening and analysis, ensuring that the site selection process is comprehensively analyzed based on multiple data sources.

[0020] Step S3: The plot screening unit performs plot screening on the geographic data to obtain a set of plots in the intended area.

[0021] Specifically, the loaded geographic data is screened using the plot screening unit according to pre-set screening conditions. The screening conditions may include land use, area range, whether it is in a specific area, etc. By comparing the attributes of each plot in the geographic data, the plots that meet the conditions are screened out to form a set of plots in the intended area. For example, if you need to select a plot for the construction of a residential project, the screening unit will exclude those plots that cannot be used for residential development, such as commercial, industrial land or plots in environmental protection areas through analysis of planning information. At the same time, the current situation will be considered, and those vacant or undeveloped lands will be selected, and plots that have been developed or have obstacles will be excluded. The set of plots in the intended area formed after screening is a set of candidate plots that meet the project requirements, providing an important reference for subsequent site selection work.

[0022] Step S4: Perform a multi-dimensional integrated analysis on the plot set in the intended area according to the scheme analysis unit to obtain multi-dimensional analysis information of the plot scheme.

[0023] Specifically, the program analysis unit is used to conduct an in-depth analysis of the intended area plot collection from multiple dimensions such as status, planning, control, ownership and supporting facilities, and obtain detailed analysis information about each plot, which is then summarized to form multi-dimensional analysis information of the plot plan. For example, when evaluating a plot, the program analysis unit will comprehensively consider the current building distribution, topography and other current conditions around the plot, analyze the planning and development potential of the plot, control requirements (such as whether it meets the relevant policy requirements of high-tech industries), whether the ownership is clear, and the degree of perfection of surrounding supporting facilities (such as scientific research institutions, transportation facilities, etc.), and summarize these analysis results to form multi-dimensional analysis information of the plot plan, providing comprehensive reference data for subsequent project site selection decisions.

[0024] Step S5: Based on the consultation and review unit, split-screen comparison and consultation and review decision-making are performed on the multi-dimensional analysis information of the plot plan and the set of plots in the intended area to determine the project site selection decision plan.

[0025] Specifically, through the consultation and review unit, the multi-dimensional analysis information of the plot plan and the set of plots in the intended area are compared and displayed on a split screen, and relevant experts, department representatives and other personnel are convened to discuss and review the decision, integrate the opinions of all parties, consider various factors, and finally determine the project site selection decision plan. Through the consultation and review unit, the advantages and disadvantages of different plans are objectively compared, and scientific decision support is provided to decision makers, avoiding the interference of subjective factors in site selection decisions, and improving the scientific nature and work efficiency of site selection. For example, in the site selection decision process of a large shopping mall, the visualization display software can display the multi-dimensional analysis information of the plot (such as management information, planning information, approval information, surrounding status information, etc.) and the location, area, etc. of the intended plot on a split screen to the participating business experts, urban planners, developer representatives and other personnel, who will discuss and make decisions based on this information to determine the final site selection plan.

[0026] Furthermore, step S3 of the embodiment of the present application also includes: Step S31: Acquire a site selection screening source, wherein the site selection screening source includes a property rights perspective, a planning perspective, and a potential pool perspective.

[0027] Step S32: According to the site selection screening source, screening conditions are set, and the screening conditions include regional scope, land scale and planning requirements, management and control requirements, current status requirements and ownership requirements.

[0028] Step S33: superimposing the target area with the geographic data through spatial overlay analysis to obtain regional plot data.

[0029] Step S34: using an asynchronous thread to perform plot screening on the regional plot data according to the screening conditions to obtain a plot screening result, wherein the plot screening result includes a set of intended regional plots.

[0030] Specifically, the site selection screening sources are obtained according to the type of site selection project. These site selection screening sources are multiple perspectives or data sources that provide basic information for site selection, including property rights perspective, planning perspective and potential pool perspective, which provide different consideration directions for the subsequent setting of screening conditions. Among them, the property rights perspective is to evaluate whether the land has the legal qualifications for development from the perspective of land ownership and legality, such as the type of land owner, the integrity of land property rights, etc.; the planning perspective is to evaluate whether the land meets the existing urban planning requirements from the perspective of urban planning, such as the planned use of the land, the planned development direction, etc.; the potential pool perspective is to consider the future development potential of the land, the future economic growth, regional development, traffic improvement and other factors of the land, and predict whether the land has a higher development value in the future.

[0031] Set specific screening conditions based on the site selection screening sources obtained and the project space requirements. These screening conditions cover aspects such as regional scope, land scale and planning requirements, control requirements, current status requirements and ownership requirements. Regional scope limits the geographical scope or area where the plot is located, such as it must be within a certain administrative district of the city. Land scale and planning requirements limit the required area and functional requirements of the plot, such as the land scale must be no less than 10 hectares and planned for elderly care. Control requirements clarify the restrictions on the control conditions of the plot, such as whether it belongs to an ecological protection area, whether there are building height restrictions, etc. The current status requirements stipulate the current use status of the plot, such as whether it has been developed or whether there are special obstacles (such as pollution, construction, etc.). Ownership requirements clarify the specific requirements for the ownership or use rights of the plot, such as whether the land ownership is clear and whether there are disputes.

[0032] Using the spatial overlay analysis function of the Geographic Information System (GIS), the target area is overlaid with geographic data including plot boundaries, planning information, control areas, current conditions and ownership information, and the target area is overlaid with the plot data to obtain regional plot data including detailed geographic information of each plot. Among them, the target area is a large spatial range pre-set for site selection of construction projects.

[0033] Asynchronous thread technology is used to screen multiple regional plot data in parallel. Each screening thread independently processes a regional plot data according to the set screening conditions, and finally obtains the screening results of plots that meet the screening conditions, that is, the intended regional plot set. Among them, asynchronous threads refer to threads that can be executed independently, allowing screening operations on multiple plot data at the same time, thereby improving screening efficiency, quickly and accurately finding plots that meet specific requirements, and narrowing the analysis scope for subsequent plot plan analysis.

[0034] Furthermore, step S3 of the embodiment of the present application also includes: Step S35: When the land parcel screening result does not meet the screening condition, a multiple screening method is obtained, and the multiple screening method includes multiple rounds of screening, reset screening, online and offline combination and manual judgment.

[0035] Step S36: Obtaining situation information that does not meet the screening conditions, the situation information includes a large number of screening results, dissatisfaction with the screening results, screening involving confidential data, and involving special plots.

[0036] Step S37: According to the situation information, the multi-screening method is used to match the plot screening results to perform multi-screening of plots.

[0037] Specifically, when the results of the plot screening do not meet the screening conditions, a multivariate screening method is obtained from a pre-set strategy or method library. These multivariate screening methods are a set of various screening methods prepared to deal with different unsatisfactory screening situations, including multiple rounds of screening, reset screening, online and offline combination, and manual judgment. Multiple rounds of screening can refine the screening by gradually relaxing or tightening the conditions, or adding new data sources. If the screening conditions are not set appropriately, the parameters can be adjusted by resetting the screening and screening again. For some plots involving complex conditions, a combination of online and offline methods can also be used, that is, using digital tools to conduct preliminary screening of the plots, and then verifying the feasibility of these plots through offline field visits. In some cases, automatic screening may have limitations, and manual judgment provides a decision-making method led by an expert team.

[0038] Compare the plot screening results with the screening conditions and identify specific situations where the screening conditions are not met. Possible situations where the screening conditions are not met include but are not limited to the following: (1) There are too many screening results, that is, there are too many plots screened out and it is impossible to quickly identify suitable plots. (2) Dissatisfaction with the screening results, that is, although the screened plots meet the basic conditions, they are not ideal from multiple perspectives such as function and location, resulting in the need for further optimization of the screening results. (3) Screening of confidential data, that is, during the screening process, some plot data may contain sensitive or confidential information, and such data requires special processing or review. (4) When it comes to special plots, that is, when it comes to plots with irregular shapes or complex terrain, the screening of such plots is more difficult and cannot be processed according to the normal screening process.

[0039] Adjust the screening strategy according to the specific situation information identified, and select the appropriate method in the multi-screening method to perform multi-screening on the plot screening results. When the number of screening results is too large, you can use multiple rounds of screening to adjust the screening conditions (such as narrowing the area or increasing the lower limit of the land use scale, etc.) to screen again, achieve funnel screening, and finally get an accurate result. When you are not satisfied with the screening results, you can reset the screening and reset the screening conditions based on any round of screening results. When it comes to the screening of confidential data, you can use a combination of online and offline methods to export the screening results, and then re-import the results into the screening process after the confidential stand-alone screening. When it comes to special plots, such as those that are not square or have many buildings, you can directly eliminate plots that do not meet the conditions based on manual judgment.

[0040] By introducing multiple screening methods and situation information feedback mechanisms, different screening methods can be flexibly selected according to different screening problems, which further optimizes the land screening process. This allows us to maintain efficiency and accuracy in the complex screening process, ensuring that the land that best suits the project needs is ultimately screened out.

[0041] Furthermore, step S4 of the embodiment of the present application also includes: Step S41: Obtaining land parcel plan analysis dimensions, wherein the land parcel plan analysis dimensions include current situation analysis, planning analysis, management and control analysis, ownership analysis, and supporting analysis.

[0042] Step S42: performing two-dimensional and three-dimensional integrated analysis and comparative analysis on the intended area plot set according to the plot plan analysis dimensions to obtain multi-dimensional analysis information of the plot plan.

[0043] Specifically, the plot solution analysis dimensions refer to different angles used to conduct a comprehensive analysis of the plot set in the intended area. The plot solution analysis dimensions are obtained from the pre-set analysis framework or project requirements document. These dimensions include status analysis, planning analysis, control analysis, ownership analysis, and supporting analysis, which form the basis for a comprehensive analysis of the plot set in the intended area.

[0044] The current situation analysis examines the current actual situation of the plot through the existing land information database to understand whether the plot meets the basic needs of the project, including checking the specific location of the plot, the purpose of the plot, the status of existing buildings, topography (slope and elevation of the land), etc. Planning analysis is to evaluate the future development direction and use planning of the plot based on the planning documents of the city or region, such as the city master plan, land master plan, detailed plan and other spatial planning requirements, to determine whether the plot meets the expected land use (such as residential, commercial, industrial, etc.) and whether there are planning restrictions or requirements. Control analysis determines whether there are control restrictions on the plot by consulting relevant regulations, such as ecological environment protection, natural resource protection, historical and cultural protection, spatial resource allocation, urban support system, spatial control form and other fields of planning and control. Ownership analysis mainly focuses on the ownership and use rights of the plot, whether there are land disputes, and whether there are legal development conditions. Supporting analysis examines the supporting infrastructure around the plot, such as roads, transportation stations, water affairs, environment and other infrastructure, as well as the completeness of surrounding public supporting facilities such as education and medical care.

[0045] According to the obtained plot plan analysis dimensions, the geographic information system (GIS) and other tools are used to conduct a two-dimensional and three-dimensional integrated analysis of each plot in the intended area plot set, that is, the two-dimensional and three-dimensional information of each plot is integrated for analysis. Two-dimensional analysis includes the plane attributes of the plot, such as area, shape, and transportation network layout; while three-dimensional analysis considers three-dimensional factors such as the height limit, skyline, and visual field of the plot. For example, when analyzing the site selection of an urban park, GIS is used to integrate the two-dimensional boundary of the park plot, the layout of the surrounding roads, and other information with the three-dimensional terrain undulations, the height of existing trees, and other information to analyze the terrain utilization and landscape sight of the park. For each analysis dimension, the two-dimensional and three-dimensional integrated analysis results of each plot are compared to analyze the advantages and disadvantages of these plots in terms of current status, planning, control, ownership, and supporting facilities. Combining these analysis results, multi-dimensional analysis information of the plot plan is obtained, which comprehensively reflects the situation of each plot in each dimension and provides solid data support for the final site selection decision.

[0046] Furthermore, step S4 of the embodiment of the present application also includes: Step S43: Calculate and obtain the school district degree gap value of the set of plots in the intended area.

[0047] Step S44: Based on the interval range of the school district's degree gap value, obtain the degree warning level, and construct warning prompt information according to the degree warning level.

[0048] Step S45: Write the degree warning level and the warning prompt information into the working layer after the warning, and supplement the multi-dimensional analysis information of the plot plan.

[0049] Specifically, in urban planning, educational resources are a very important part, especially when it comes to project site selection in residential areas or densely populated areas. The distribution of schools and degrees directly affects the social acceptance and sustainable development of the project. Therefore, when making site selection decisions for construction projects, it is necessary to consider the impact of educational resources on project site selection.

[0050] The school district degree gap value is a numerical value that measures the degree of imbalance between the supply and demand of school district degrees within the intended area plot set. The degree gap value is calculated by analyzing the degree distribution of the school district where the intended area plot set is located. Based on the calculated degree gap value, the corresponding degree warning level is set. Different gap value ranges correspond to different warning levels, which are usually divided into normal, warning, and severe warning levels: Normal: The gap value is small, and the school district has basically sufficient degrees; Warning: The degree gap exists, but it is still within an acceptable range; Severe warning: The degree gap is large, and the educational resources in the school district are seriously insufficient. This warning level can reflect the tension of degree supply in the school district. Using the rule engine, the calculated school district degree gap value is used to determine the range of its range, so as to determine the corresponding degree warning level. Then, according to the degree warning level, the corresponding warning prompt information is constructed to explain in detail the current status of degree supply and demand and the possible impact, so that decision makers can make timely adjustments and countermeasures. For example, if there is a 200-degree gap in school district A, it is recommended to consider building a new school or choosing another school district.

[0051] A working layer refers to a map layer that displays data or analysis results in a graphical way. Different layers can display different spatial data, such as plot location, traffic conditions, school district boundaries, etc. In the original multi-dimensional analysis information of the plot plan, the degree warning level and warning prompt information are added to form a new working layer that includes education resource analysis, providing a scientific basis for education planning and school site selection, and ensuring the rational allocation and sustainable development of education resources.

[0052] Furthermore, step S43 of the embodiment of the present application further includes: Step S431: Calculate the school district information of the intended area plot set by means of SQL statements, and extract the geographic coordinate information of the school district information.

[0053] Step S432: extracting and arranging information of each school in the school district from the school layer based on the geographic coordinate information to generate the educational resource situation of the school district.

[0054] Step S433: Perform a statistical analysis on the degree supply and demand and calculate the degree gap number for the school district information to obtain the degree gap value for the school district.

[0055] Specifically, in order to effectively evaluate the supply and demand of school places and calculate the school place gap value, first, the school district information of the intended area plot set is obtained from the database containing school district related data through SQL statements. Through SQL query, the school district where each plot is located can be determined, and the boundaries, names and other relevant geographic information of the school district can be obtained. At the same time, the geographic coordinate information of the school district is extracted, which includes the latitude and longitude data of the school district, to provide support for subsequent map visualization and spatial analysis.

[0056] The obtained school district geographic coordinate information is used as a screening condition to query the school layer in the geographic information system (GIS). The school layer refers to the map layer that displays the school's geographic location and related information, usually including the school's specific location, number of degrees, school type (such as elementary school, junior high school or high school) and other data. By matching the geographic coordinate information, the information of each school in the school district corresponding to each plot is extracted from the school layer, including the school name, number of degrees, number of classes, and grade distribution. Then, this information is sorted, for example, classified and counted according to school type, size, etc., to generate the school district's educational resources.

[0057] According to the generated school district education resources, the supply and demand of school places in the school district are statistically analyzed. The total number of school places available in each school in the school district is calculated based on information such as school size, and the school-age population demand of the school district is calculated based on existing or predicted population data. The school district's school place gap value is then calculated based on the difference between the two, providing specific data basis for subsequent evaluation of the distribution and overall situation of the school district's education resources, so as to make more reasonable project site selection decisions.

[0058] Further, such as Figure 2 As shown, step S5 of the embodiment of the present application also includes: Step S51: Generate a preliminary report outline based on the intended area plot set and the multi-dimensional analysis information of the plot plan.

[0059] Step S52: adjusting the preliminary report outline according to the demand information to form a site selection report outline.

[0060] Step S53: According to the site selection report outline, determine the scene base plate, select and use the marking tool, display window tool and preview tool to produce the scene content for the scene base plate, and obtain the outline scene content information.

[0061] Step S54: Select upload data in the data center directory according to the consultation demand information and configure the consultation data.

[0062] Step S55: Preview the topic presentation effect based on the meeting topic, the site selection report outline, the outline scene content information and the consultation data to confirm that the report requirements meet the results.

[0063] Step S56: When the report requirements are met and the results are confirmed, they are pushed to the two-dimensional and three-dimensional consultation system for online demonstration and reporting decision-making to determine the project site selection decision plan.

[0064] Specifically, consultation demand information refers to the content or data that decision makers need to focus on discussing and analyzing during the project decision-making process. Consultation needs vary depending on the project type and decision-making process. The data center directory is a directory structure that stores various types of data, including plot information, planning data, degree information, etc. Consultation data refers to the data content prepared for the decision-making meeting, which is usually screened, sorted and provided to decision makers in an appropriate format. The two-dimensional and three-dimensional consultation system is a system for online presentation and reporting decisions, which can process two-dimensional and three-dimensional geographic information and related data. In this system, decision makers can demonstrate, discuss and make final decisions on site selection plans.

[0065] Extract key information from the intended area plot set, such as the number, location, area, etc. of the plots, and then combine the analysis results of each dimension in the multi-dimensional analysis information of the plot plan (current situation, planning, control, ownership, supporting facilities, etc.), and generate a preliminary report outline according to the pre-set reporting order. For example, first introduce the overall situation of the intended area plot set, and then explain the characteristics and problems of the plots from each analysis dimension to form a preliminary framework report outline. This outline will outline the background of the project site selection, the analysis dimensions of each plot, the degree gap, transportation and environmental factors, etc., to ensure that the subsequent report content covers all important information.

[0066] Interact with users to obtain specific consultation requirements or reporting needs, such as whether certain specific indicators (such as transportation convenience, environmental impact, educational resources, etc.) need to be emphasized. Adjust the order and sub-directory nodes of the preliminary report outline based on actual demand information to highlight the key content of decision makers' concerns, making the adjusted report outline more refined and targeted.

[0067] Next, create a visualization of the report based on the adjusted site selection report outline. First, determine a basic map or scene base. If the report outline focuses on plots in an urban area, the scene base may choose a map of the city as the basis. Then use the plotting tool to mark the location of the plot and display the relevant analysis data of each plot (such as transportation, school district, etc.). Use the display window tool to provide a detailed information box to display the properties and analysis results of the plot. In addition, use the preview tool to view and adjust the scene content, check the final effect, and ensure that the visualization content of the report is clear and easy to understand.

[0068] According to the consultation requirements, select and upload relevant data from the data center directory. These data will be used for meeting discussions and decision support. According to the key content of the report (such as transportation, environmental impact, degree gaps, etc.), select the corresponding data set and configure it to ensure that all necessary background information can be fully presented in the meeting.
