Description

Technical Field

[0001] This invention relates to the field of land planning technology, and in particular to a method and system for site adjustment of land resources. Background Technology

[0002] In the fields of territorial spatial planning, intensive use of land resources, and regional sustainable development, the scientific allocation of land resources is the core approach to balancing the three major needs of economic development, social welfare, and ecological protection, and is directly related to the quality of regional development and the efficiency of resource utilization.

[0003] Currently, the mainstream methods for allocating land resources rely on traditional economic analysis models, such as the Gini coefficient method, data envelopment analysis (DEA) models, and simple input-output coupling analysis. These methods typically assess land use efficiency from a single dimension, for example, by measuring the balance of resource allocation by calculating the degree of matching between land transfer area and industrial added value, main business revenue, or number of employees.

[0004] Regarding the aforementioned technologies, in the actual process of allocating land resources, most land allocation methods rely on subjective human judgment, resulting in land regulation failing to keep pace with the actual situation. Therefore, there is still room for improvement in the real-time nature of land resource regulation. Summary of the Invention

[0005] To improve the real-time performance of land resource regulation, this invention provides a method and system for site regulation of land resources.

[0006] In a first aspect, the present invention provides a method for site adjustment of land resources, employing the following technical solution:

[0007] A method for site adjustment of land resources, comprising:

[0008] Step 1: In response to a preset land adjustment signal, acquire multi-source land data;

[0009] Step 2: Calculate land adjustment information based on multi-source land data and a preset adjustment algorithm;

[0010] Step 3: Select any single land parcel from the land adjustment information;

[0011] Step 4: Analyze the information of individual land parcels to obtain information on their intended use;

[0012] Step 5: Locate the actual usage information corresponding to a single land parcel in the multi-source land data;

[0013] Step 6: Adjust the actual usage information according to the needs and uses information to obtain updated adjustment information and output it.

[0014] By adopting the above technical solution, land adjustment information is obtained through multi-source land data. A piece of land is selected and its corresponding demand and use information is obtained. Then, the corresponding actual use information is found. Finally, the actual use information is adjusted according to the demand and use information, so that land resources can be planned in a reasonable and timely manner according to actual needs, thereby improving the real-time performance and accuracy of land resource adjustment.

[0015] Optionally, methods for analyzing individual land parcel information to obtain demand and use information include:

[0016] Step 40: Count the number of uses in the information of a single land parcel;

[0017] Step 41: If the number of uses is greater than 1, break down the information of a single land parcel to obtain multiple use information;

[0018] Step 42: Sort the usage information according to the preset ignore rules to obtain the usage ranking;

[0019] Step 43: Output the usage information sequentially based on usage order and integrate them to obtain the required usage information;

[0020] Step 44: If the number of land uses is equal to 1, analyze the information of a single land parcel to obtain the required land use information.

[0021] By adopting the above technical solution, the use of a single piece of land is statistically analyzed, and multiple uses are sorted and integrated according to the ignore rule to form a use ranking, so as to obtain demand use information. The single use is directly analyzed and determined, making the determination of land demand use more orderly and reasonable. This avoids blindly implementing the adjustment plan after obtaining the land resource adjustment plan, and improves the standardization and applicability of land use planning.

[0022] Optional, also includes:

[0023] Step 440: Obtain new land information and supplementary demand information;

[0024] Step 441: Extract new land use information from the new land information;

[0025] Step 442: If the supplementary information and the new land use information are consistent, merge the new land information and the land adjustment information to obtain comprehensive information and output it.

[0026] Step 443: If the supplementary information for the demand is inconsistent with the new land use information, find the corresponding adjustment information in the land adjustment information through the new land information;

[0027] Step 444: Adjust the adjustment information according to the required supplementary information and update the land adjustment information;

[0028] Step 445: Based on the fusion of new land information and updated land adjustment information, updated comprehensive information is obtained.

[0029] By adopting the above technical solution, new land use information is obtained through new land information and compared with the supplementary demand information. If the two are consistent, the new land information is directly integrated to optimize the adjustment plan. If they are inconsistent, the corresponding adjustment information is found and adjusted and updated. Finally, a comprehensive adjustment plan that adapts to actual needs is generated, thereby improving the rationality and accuracy of land resource allocation.

[0030] Optionally, methods for finding corresponding adjustment information in land adjustment information using new land information include:

[0031] Step 4430: Locate the land information exchange group in the land adjustment information using the new land information;

[0032] Step 4431: Extract the reconstruction information group from the land adjustment information;

[0033] Step 4432: Filter redevelopment exchange information based on the land exchange information group and the redevelopment information group;

[0034] Step 4433: If the modification exchange information exists, define the modification exchange information as adjustment information and output it;

[0035] Step 4434: If the reconstruction and exchange information does not exist, extract the available information from the new land information;

[0036] Step 4435: When the available information includes demand supplement information, replace the new land information with the demand supplement information to obtain new land supplement information and merge it with the land adjustment information to obtain new land redevelopment information.

[0037] By adopting the above technical solution, the exchange land information group and reconstruction information group are searched in the land adjustment information based on the new land information. The two groups of information are then filtered to obtain the reconstruction exchange information. If reconstruction exchange information exists, it is output as adjustment information. If it does not exist, the available information in the new land information is extracted. When the available information contains supplementary demand information, it replaces the new information and is integrated with the land adjustment information to improve the pertinence and rationality of land resource utilization.

[0038] Optionally, if modification exchange information exists, methods for defining and outputting modification exchange information as adjustment information include:

[0039] Step 44330: Extract human resources information from the reconstruction and exchange information;

[0040] Step 44331: If human information exists, collect the corresponding surrounding land information based on the new land information;

[0041] Step 44332: When the land information falls into the preset traffic information, define the reconstruction and exchange information as adjustment information and output it;

[0042] Step 44333: If human resources information does not exist, define the modified exchange information as adjustment information and output it.

[0043] By adopting the above technical solution, when the information exchanged for reconstruction exists, the human resources information is extracted first. If there is human resources information, further information about land is collected and combined with traffic information for judgment. If there is no human resources information, the adjustment information is directly determined, making the judgment of land adjustment more in line with the on-site implementation conditions and improving the feasibility and practicality of the land adjustment plan.

[0044] Optionally, methods for sequentially outputting and integrating usage information based on usage order to obtain required usage information include:

[0045] Step 430: Based on actual usage information and sorting by purpose, obtain the reconstruction information group and the continuous construction information group;

[0046] Step 431: Locate reconstruction replacement information based on the reconstruction information group;

[0047] Step 432: If reconstruction and replacement information exists, form demand and use information based on the reconstruction and replacement information and the continuous construction information group;

[0048] Step 433: If the reconstruction and replacement information does not exist, output the usage information in order of usage and integrate it to obtain the required usage information.

[0049] By adopting the above technical solutions, and combining actual usage information with the use order to divide the reconstruction information group and the continuous construction information group, and forming or integrating the demand use information according to whether reconstruction replacement information exists, the land use planning is more in line with the existing construction status, avoiding unreasonable reconstruction and waste of resources, and improving the scientificity and consistency of land regulation.

[0050] Optionally, if reconstruction and replacement information exists, methods for forming demand and use information based on the reconstruction and replacement information and the continuous construction information include:

[0051] Step 4330: Receive construction requirement information;

[0052] Step 4331: Based on the reconstruction information group and the continuous construction information group, extract the corresponding construction continuity information from the construction demand information;

[0053] Step 4332: Extract the last construction information from the reconstruction information group and the last construction information from the continuous construction information group;

[0054] Step 4333: If both the end construction information and the following construction information exist in the construction continuity information, output the usage information sequentially based on the usage order and integrate them to obtain the required usage information;

[0055] Step 4334: If the end construction information or the end construction information is not in the construction continuity information, the demand and use information is formed based on the reconstruction replacement information and the continuous construction information.

[0056] By adopting the above technical solution, when reconstruction and replacement information exists, construction continuity information is extracted by combining construction demand information, the end construction information is matched and judged with the following construction information, and then it is decided whether to separate the reconstruction and replacement information and the continuous construction information group to form demand and use information, so that the determination of land demand and use is more in line with the overall construction plan and improves the continuity and rationality of land adjustment scheme.

[0057] Alternatively, other methods for obtaining information on the intended use of the information include:

[0058] Step 45: Obtain historical land information;

[0059] Step 46: Sort the historical land information according to the preset time rules to obtain the historical ranking;

[0060] Step 47: Output historical land information sequentially based on historical sorting and analyze it to obtain information on land changes;

[0061] Step 48: Calculate and predict land information based on land changes;

[0062] Step 49: Extract the predicted land use information from the predicted land information, define it as demand use information, and output it.

[0063] By adopting the above technical solutions, historical land information is obtained and sorted and analyzed according to time rules to obtain land change information and calculate and predict land information. The predicted land use information is used as demand land use information, making land use planning more forward-looking and improving the rationality and predictability of land resource regulation.

[0064] Optionally, methods for adjusting actual usage information based on demand and purpose information to obtain updated adjustment information and output it include:

[0065] Step 60: Locate the corresponding set of surrounding land information based on the information of a single land parcel;

[0066] Step 61: Extract the enclosing use information from the enclosing land information set;

[0067] Step 62: Combine the required usage information with the surrounding usage information to obtain coherent requirement information;

[0068] Step 63: Adjust the actual usage information according to the coherent demand information to obtain updated adjustment information and output it.

[0069] By adopting the above technical solution, the land adjustment plan is coordinated with the surrounding land use situation, planning conflicts are avoided, and the overall integrity and adaptability of land resource adjustment are improved.

[0070] Secondly, the present invention provides a site adjustment system for land resources, which adopts the following technical solution:

[0071] A site regulation system for land resources, comprising:

[0072] The acquisition module is used to acquire multi-source land data, new land information, demand supplement information, construction demand information, and historical land information;

[0073] A memory for storing a program for a site adjustment method for land resources as described above;

[0074] The processor loads and executes programs from memory.

[0075] By adopting the above technical solution, the acquisition module collects various land-related information such as multi-source land data, and in conjunction with the memory and processor, the land adjustment method is automatically executed. This enables the rapid and stable completion of site adjustment analysis and scheme output, ensuring the automation level and operational efficiency of land resource adjustment, and improving the real-time performance and accuracy of land resource adjustment.

[0076] In summary, the present invention has at least one of the following beneficial technical effects:

[0077] 1. By obtaining land adjustment information through multi-source land data, selecting a piece of land and obtaining its corresponding demand and use information, then finding the corresponding actual use information, and finally adjusting the actual use information according to the demand and use information, land resources can be planned reasonably and in a timely manner according to actual needs, thus improving the real-time performance and accuracy of land resource adjustment.

[0078] 2. By prioritizing the construction of land with multiple needs and then building facilities according to the priority, safety hazards during construction can be avoided, while also enabling efficient and accurate construction, thus improving construction efficiency. Attached Figure Description

[0079] Figure 1 This is a flowchart of a land resource site adjustment method according to an embodiment of this application. Detailed Implementation

[0080] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0081] This invention discloses a method for site adjustment of land resources. (Refer to...) Figure 1 A method for site adjustment of land resources includes:

[0082] Step 1: In response to a preset land adjustment signal, acquire multi-source land data.

[0083] The land adjustment signal refers to the instruction signal that initiates the land resource allocation process in the system. The response method here is as follows: personnel in the field configure the cycle parameters. The system has a built-in timing module that resets the timing and begins accumulating after each land allocation is completed. When the timing duration reaches the cycle threshold, the system automatically generates and sends out this signal, or it can be triggered by personnel in the field pressing the system's own electrical signal button.

[0084] Multi-source land data refers to a collection of structured and unstructured data covering multiple dimensions of land, including basic attributes, utilization dynamics, industrial linkages, planning control, and historical allocation and usage. This data is used to support the calculation of evaluation indicators and the updating of algorithms. The acquisition of multi-source land data involves the system collecting data on land ownership, land type, usage status, industrial input and output, planning parameters, and historical records through multiple channels, including the national land spatial information platform, remote sensing satellite monitoring, drone aerial photography, local statistical departments, and industrial park management systems. This data is then standardized, processed, and integrated to form multi-source land data.

[0085] Step 2: Calculate land adjustment information based on multi-source land data and a preset adjustment algorithm.

[0086] The adjustment algorithm refers to a set of calculation formulas for generating reasonable site adjustment schemes based on multi-source land data. Specifically, the adjustment algorithms here are: 1. Industry Importance Algorithm – Industry importance equals the industry's land share plus the product of the adjustment parameter and the normal priority coefficient, then divided by the total number of industries. The adjustment parameter here is set to 1.0 by default; 2. Input-Output Coupling Algorithm – Input-output coupling degree equals 1 minus the sum of the absolute differences between the cumulative land input ratio and the cumulative economic output ratio of the i-th industry or region, then divided by the total number of samples. The resulting C is... d The closer to 1, the higher the matching degree between land input and output; 3. Per-acre benefit algorithm - per-acre benefit equals the sum of main business revenue and taxes paid divided by the land area (acres); 4. Factor comprehensive guarantee index algorithm - CFAI is the comprehensive factor guarantee index, and α (alpha), β (beta), and γ (gamma) all represent weights. For example, if α (alpha) is 0.4, and β (beta) and γ (gamma) are both 0.3, the weights of the comprehensive guarantee index algorithm will be updated here. Specifically, the system decomposes multi-source land data, extracts historical land allocation records and corresponding actual usage data, determines the actual contribution of each indicator through comparative analysis, and adjusts and replaces the weight coefficients of α (alpha), β (beta), and γ (gamma) in the comprehensive algorithm accordingly. 5. Linear Programming Model - ,in T max x is the upper limit of the total land area. i ≥0 (non-negativity constraint), x i =0 for ecological red lines, basic farmland, and other prohibited development areas, x i Less than or equal to U i U i The maximum land supply limit for each industry / region is determined by objective physical constraints such as the physical boundary of the ecological red line, the geographical fence of basic farmland, and the elevation limit of the on-site terrain. The algorithm is not a simple mathematical programming method, but runs on an embedded processor or a dedicated land regulation server. It calculates based on land status data collected in real physical space, and the calculation results are directly used to drive subsequent physical regulation actions.

[0087] Land adjustment information refers to a structured data set of recommended land supply areas for various industries or regions. The land adjustment information is obtained by the system substituting multi-source land data into three indicators: industry importance algorithm, input-output coupling algorithm, and per-acre benefit algorithm. These indicators are then substituted into the factor comprehensive guarantee index algorithm for weighted fusion to obtain the guarantee index (CFAI). Finally, the system is substituted into a linear standard model, aiming to maximize the total CFAI. Under constraints such as the upper limit of total land area, non-negativity constraints, restrictions on prohibited development areas, and maximum land supply limits for each industry, the system uses optimization tools such as PuLP and Gurobi to solve the problem, ultimately outputting the recommended land supply area for each industry or region to obtain the land adjustment information.

[0088] Step 3: Select any single land parcel from the land adjustment information.

[0089] Single land parcel information refers to the set of data related to a single land parcel with independent ownership, independent spatial scope, or independent planning unit, obtained by splitting it from land adjustment information. The selection method for single land parcel information here is that the system randomly extracts or sequentially selects the data of one parcel from the entire set of land parcels included in the land adjustment information as the current processing object.

[0090] Step 4: Analyze the information of individual land parcels to obtain information on their intended use.

[0091] Demand and use information refers to the specific functional types of the land parcel that are planned for future redevelopment or use, such as green space, residential, park, commercial, and public services. The analysis of this demand and use information involves the system determining the suitability of the land parcel based on individual land parcel information, overall regional planning, and land adjustment schemes, extracting and identifying the specific uses that need to be developed, such as green space, residential, or recreational parks.

[0092] Step 5: Locate the actual usage information corresponding to a single land parcel in the multi-source land data.

[0093] Actual usage information refers to the current actual use status, surface attachments, construction layout, and actual function of a single land parcel. The method for finding this information involves the system using the parcel number, spatial coordinates, or ownership scope from the single land parcel information as search criteria. This involves matching and searching through multi-source land data to extract the corresponding current status survey data, remote sensing image interpretation results, and field survey records, which are then summarized to obtain the current actual usage information.

[0094] Step 6: Adjust the actual usage information according to the needs and uses information to obtain updated adjustment information and output it.

[0095] Updated adjustment information refers to the final land planning adjustment scheme formed after adjusting the existing actual use information of a single plot of land based on demand and usage information. The generation of updated adjustment information involves the system comparing demand and usage information with actual use information, identifying differences, and generating adjustment instructions such as demolition, new construction, functional conversion, and spatial optimization based on these differences. This information is then integrated to form a complete plot adjustment scheme, which is output as updated adjustment information. The system then converts the updated adjustment information into executable physical control instructions, outputting them to land consolidation equipment, construction scheduling terminals, or intelligent planning execution platforms. This directly guides on-site physical modification actions such as demolition, new construction, greening, and functional transformation, achieving actual control over the actual land space.

[0096] Methods for analyzing individual land parcel information to obtain demand and usage information include:

[0097] Step 40: Count the number of uses in the information of a single land parcel.

[0098] The number of uses refers to the total number of specific planned uses for a single plot of land. This number is obtained by parsing the land use list for each plot in the land adjustment information, deduplicating the use types in the list, and then calculating the number of uses for that single plot. For example, if the planned uses are building and green space, the number of uses is 2; if the planned uses are park, green space, and subway, the number of uses is 3.

[0099] Step 41: If the number of uses is greater than 1, break down the information of a single land parcel to obtain multiple use information.

[0100] Land use information refers to the detailed collection of all planned uses for a land parcel. This information is obtained by the system extracting the multi-use planning details of the land parcel from land adjustment information, and then summarizing the relevant parameters for each use to form complete land use information.

[0101] If the number of land uses is greater than 1, it means that the single piece of land needs to be used for the construction of multiple facilities, which may require multiple constructions. Therefore, the information of a single piece of land is broken down to obtain multiple use information.

[0102] Step 42: Sort the usage information according to the preset ignore rules to obtain the usage sort.

[0103] Ignore rules refer to pre-defined construction priority ranking rules that prioritize projects that will not affect subsequent projects during the construction process. These ignore rules are obtained by professionals in the field through experiments to determine the order in which various construction activities will not affect the order of construction, and then inputting this information into the system. Land use ranking refers to the sequence formed by prioritizing multiple land use information items for a single plot of land. This land use ranking is obtained by the system retrieving ignore rules, matching the various land use information items of the target plot against the priority criteria in the rules, sequentially filtering out uses that will not affect subsequent construction and ranking them first, then ranking the remaining uses according to the rules to generate the land use ranking.

[0104] Step 43: Output the usage information sequentially based on usage order and integrate them to obtain the required usage information.

[0105] The method for obtaining the demand and use information here is that the system extracts the construction content, implementation sequence and functional requirements from each use information in order of use, and then merges them into a complete land use implementation plan according to the construction sequence to form the demand and use information.

[0106] Step 44: If the number of land uses is equal to 1, analyze the information of a single land parcel to obtain the required land use information.

[0107] If the land use quantity is equal to 1, it means that only one type of facility needs to be built on the single plot of land, and there is no need to consider mutual influence. Therefore, the information of a single plot of land is analyzed to obtain the demand use information.

[0108] This also includes:

[0109] Step 440: Obtain new land information and supplementary demand information.

[0110] New land information refers to the complete set of relevant data for newly added land parcels included in the planning scope. This new land information includes geographical location, area, topography, soil properties, ownership status, surrounding facilities, ecological and environmental constraints, and planned uses. The system obtains this new land information by connecting to platforms such as the national land spatial planning database and the cadastral management system to collect basic survey data and ownership registration information for the newly added land parcels. Simultaneously, it supplements the environmental and supporting details of the land parcels with on-site survey results, and after aggregation and verification, forms complete new land information. Demand supplement information refers to supplementary data used to improve the site adjustment plan, including new land use demands, functional expansion requirements, or planning adjustment instructions, based on the original land adjustment plan. This demand supplement information is obtained by the system collecting new land use demands, industrial expansion requirements, and planning adjustment instructions through user input terminals, regional development planning interfaces, or project construction application platforms. It also combines this with actual on-site demand data uploaded by IoT monitoring devices to form demand supplement information.

[0111] Step 441: Extract new land use information from the new land information.

[0112] New land use information refers to a set of data related to the current actual use status and specific purpose of new land. This information is obtained by the system breaking down new land information, extracting survey records, ownership registration documents, and on-site verification results related to the current use of the land parcel, and then integrating this data to obtain the land use information.

[0113] Step 442: If the supplementary information is consistent with the new land information, merge the new land information with the land adjustment information to obtain comprehensive information and output it.

[0114] Comprehensive information refers to the complete set of site adjustment data formed by integrating and normalizing new land information with existing land adjustment information. The integration method here involves the system using spatial coordinates and plot codes as the basis for data merging, conflict verification, and planning constraint unification of new land information and land adjustment information, forming integrated information covering all regulated plots. The output method involves the system converting the comprehensive information into a standardized planning data format and outputting it to construction scheduling terminals, land planning management platforms, and on-site remediation equipment, providing a unified data basis for the unified construction and physical space control of new and existing plots.

[0115] If the supplementary information for the new land use is consistent with the information for the new land use, it means that the existing construction information for the new land can meet the requirements of the information for the new land use, and no modification is required. Therefore, the new land information and the land adjustment information are integrated to obtain comprehensive information and output.

[0116] Step 443: If the supplementary information for the demand is inconsistent with the new land use information, find the corresponding adjustment information in the land adjustment information through the new land information.

[0117] Adjustment information refers to the planning adjustment strategies, land supply indicators, and land use constraints of the same area or type of land parcels in the original land adjustment information that match the new land information. The method for finding this adjustment information is that the system uses the parcel type, spatial location, and planning attributes from the new land information as search criteria, performs a matching search in the land adjustment information, and extracts the historical adjustment schemes and constraint parameters corresponding to similar land parcels.

[0118] If the supplementary information on demand is inconsistent with the information on new land use, it means that the new land is inconsistent with the demand. However, in order to avoid modifying the new land as much as possible, the corresponding adjustment information should be found in the land adjustment information through the new land information.

[0119] Step 444: Adjust the adjustment information according to the required supplementary information and update the land adjustment information.

[0120] The land adjustment information is updated by comparing the matched adjustment information with the supplementary demand information. Based on the new land use demand, functional requirements and planning constraints, the system corrects and replaces the land supply area, use type, construction indicators and other contents in the adjustment information. The information of the adjusted land and the new land is replaced and then integrated into the original land adjustment information to complete the update.

[0121] Step 445: Based on the fusion of new land information and updated land adjustment information, updated comprehensive information is obtained.

[0122] Updating comprehensive information refers to the normalization and integration of new land information with land adjustment information adjusted by demand-supplemented information, forming a set of site adjustment data. Here, the integration method for updating comprehensive information involves the system using the spatial coordinates and ownership number of the land parcel as associated keywords to merge the new land information with the updated land adjustment information, verify planning conflicts, and unify physical constraints such as ecological red lines and topography, forming integrated planning information that can be directly used for physical construction control.

[0123] The methods for finding corresponding adjustment information in land adjustment information using new land information include:

[0124] Step 4430: Locate the exchange land information group in the land adjustment information using the new land information.

[0125] A land exchange information group refers to a collection of land parcels that are compatible with the new land information in terms of location, land area, and planning attributes, and can be exchanged for land use rights or have their spatial layout adjusted. The search method for this land exchange information group involves the system using the parcel area, spatial coordinates, land use nature, and topographical conditions of the new land information as search features to filter parcels that meet the exchange compatibility criteria from the land adjustment information, and then summarizing them to form the land exchange information group.

[0126] Step 4431: Extract the reconstruction information group from the land adjustment information.

[0127] The redevelopment information group refers to the information collection consisting of physical redevelopment contents such as demolition, new construction, functional conversion, and spatial optimization corresponding to various types of land parcels. The redevelopment information group is extracted by the system from land adjustment information to select relevant data including construction content, redevelopment scope, construction sequence, and functional adjustments, and then collects and organizes them according to land parcel categories to form the redevelopment information group.

[0128] Step 4432: Filter redevelopment exchange information based on the land exchange information group and the redevelopment information group.

[0129] Redevelopment exchange information refers to land parcels that can be exchanged for construction content with new land and that contain information related to redevelopment needs such as demolition, new construction, or functional renovation. The filtering method for this redevelopment exchange information involves the system using the land use attributes and construction needs of the new land as matching criteria to filter out land parcels that exist simultaneously in both the exchange land information group and the redevelopment information group, and then extracting their corresponding land parcel information as redevelopment exchange information.

[0130] Step 4433: If the modification exchange information exists, define the modification exchange information as adjustment information and output it.

[0131] If the reconstruction exchange information exists, it means that there are plots of land that can directly exchange construction information with the new land information. In this case, it is not necessary to reconstruct the new land. Therefore, the reconstruction exchange information is defined as adjustment information and output.

[0132] Step 4434: If the reconstruction and exchange information does not exist, extract the available information from the new land information.

[0133] Available information refers to the set of planned uses and corresponding feasibility parameters of new land based on its topography, location, supporting conditions, and policy constraints. This available information is obtained by the system extracting core data such as the area, geographical location, soil properties, surrounding infrastructure, ecological protection red line requirements, and land use planning restrictions of the new land. This data is then combined with regional development plans and land use needs to analyze and determine the specific directions and applicable conditions for the land's use, thus obtaining available information.

[0134] If the redevelopment exchange information is not available, it means that there is no land that can be directly replaced by new land to supplement the information according to the needs for redevelopment. Therefore, the available information in the new land information is extracted.

[0135] Step 4435: When the available information includes demand supplement information, replace the new land information with the demand supplement information to obtain new land supplement information and merge it with the land adjustment information to obtain new land redevelopment information.

[0136] New land supplementary information refers to new land planning data where the original planned uses have been replaced with supplementary demand information. This new land supplementary information is obtained by the system using available information as a base, replacing the original new use information with matching supplementary demand information, and then creating standardized land parcel data after updating the uses and construction needs.

[0137] When available information includes demand supplement information, it means that the new land can meet the demand and can be directly redeveloped. Therefore, the demand supplement information is replaced with the new land information to obtain new land supplement information, which is then integrated with the land adjustment information to obtain new land redevelopment information.

[0138] Among them, if reconstruction exchange information exists, the methods for defining and outputting reconstruction exchange information as adjustment information include:

[0139] Step 44330: Extract human resources information from the reconstruction and exchange information.

[0140] Human resources information refers to information related to the existing population's residence, activities, and resettlement needs on the land parcel corresponding to the redevelopment and exchange information. The extraction method for this human resources information involves the system parsing the residential status, population data, and resettlement-related parameters of the land parcel from the redevelopment and exchange information, and then filtering to obtain the relevant personnel information corresponding to that land parcel.

[0141] Step 44331: If human information exists, collect the corresponding surrounding land information based on the new land information.

[0142] Surrounding land information refers to information about other plots of land, supporting facilities, resettlement areas, and available space within a certain range around the new land. The method for collecting this surrounding land information is that the system extracts data on the surrounding plots spatially enclosing the new land from land adjustment information and summarizes this data to obtain the surrounding land information.

[0143] If human information exists, it means that the land that can be replaced by new land for reconstruction originally involved human activities. Therefore, the corresponding land information is collected based on the new land information.

[0144] Step 44332: When the land information falls into the preset traffic information, the reconstruction exchange information is defined as adjustment information and output.

[0145] Traffic information refers to information related to traffic around the land parcel. This traffic information is generated by researchers in the field who input all relevant traffic data into the system through experiments. When the system receives information about the land, it automatically compares it with the input data to determine whether it falls within the traffic information range.

[0146] When the land information falls into the preset traffic information, it means that the new land can also realize the passage and movement of people. Therefore, the reconstruction exchange information is defined as the adjustment information and output.

[0147] Step 44333: If human resources information does not exist, define the modified exchange information as adjustment information and output it.

[0148] If human resources information is not available, it means that there will be no impact on the population. Therefore, the information exchange information is defined as adjustment information and output.

[0149] Among them, the method of outputting usage information sequentially based on usage order and integrating it to obtain the required usage information includes:

[0150] Step 430: Based on actual usage information and sorting by purpose, obtain the reconstruction information group and the continuous construction information group.

[0151] The reconstruction information group refers to the set of information on facilities and corresponding land parcels that require priority construction and initial construction. This reconstruction information group is obtained by the system analyzing the actual land use information to determine the actual purpose, then matching the actual purpose with the use ranking, and extracting the relevant information of the facilities and land parcels that are ranked higher and require priority construction. The continuous construction information group refers to the set of information on facilities and land parcels that can be constructed sequentially based on the current actual purpose. This continuous construction information group is obtained by the system comparing the actual land use information with the use ranking, and filtering out relevant information that ensures continuity between the actual purpose and the planned subsequent uses, allowing for continuous construction.

[0152] Step 431: Locate reconstruction replacement information based on the reconstruction information group.

[0153] Reconstruction replacement information refers to alternative land information available for reconstruction of facilities within the reconstruction information group. The method for finding reconstruction replacement information here is that the system filters and matches suitable alternative plots in the land adjustment information based on the construction needs and land use conditions of the reconstruction information group, and then summarizes this information to form other land information available for reconstruction.

[0154] Step 432: If reconstruction and replacement information exists, form demand and use information based on the reconstruction and replacement information and the continuous construction information group.

[0155] If reconstruction and replacement information exists, it means that the facilities in the reconstruction information group can be built on other land. Therefore, demand and use information is formed based on the reconstruction and replacement information and the continuous construction information group.

[0156] Step 433: If the reconstruction and replacement information does not exist, output the usage information in order of usage and integrate it to obtain the required usage information.

[0157] If the reconstruction and replacement information is not available, it means that the land still needs to be rebuilt. Therefore, the usage information is output in order of use and integrated to obtain the required usage information.

[0158] Among them, if reconstruction and replacement information exists, the method for forming demand and use information based on the reconstruction and replacement information and the continuous construction information group includes:

[0159] Step 4330: Receive construction requirement information.

[0160] Construction requirement information refers to construction instructions for a given site, including construction goals, functional requirements, construction scale, and construction timelines. This construction requirement information is received by the system through a control terminal, where user-inputted construction-related parameters and requirements are combined.

[0161] Step 4331: Based on the reconstruction information group and the continuous construction information group, extract the corresponding construction continuity information from the construction demand information.

[0162] Construction continuity information refers to continuous construction-related information that meets construction requirements. The extraction method for construction continuity information here involves the system comparing and correlating reconstruction and replacement information, continuous construction information groups, and the received construction requirements information to filter out relevant information that demonstrates continuous construction and meets the user's construction needs.

[0163] Step 4332: Extract the end construction information from the reconstruction information group and the end construction information from the continuous construction information group.

[0164] End-of-phase construction information refers to the construction content information of the final completed or finishing stage in the reconstruction information group. The method for extracting end-of-phase construction information here is that the system extracts the construction content and related construction information of the final stage based on the construction sequence of the reconstruction information group. Successor construction information refers to the construction information in the continuous construction information group that serves to connect with end-of-phase construction information and continues construction after its completion. The method for extracting successor construction information here is that the system extracts the subsequent construction content information that can be directly connected to end-of-phase construction information based on the construction sequence of the continuous construction information group.

[0165] Step 4333: If both the end construction information and the following construction information exist in the construction continuity information, output the usage information sequentially based on the usage order and integrate them to obtain the required usage information.

[0166] If both the final construction information and the following construction information are present in the construction continuity information, it means that the subsequent buildings are related to the preceding buildings and cannot be built separately. Therefore, the usage information is output sequentially based on the usage order and integrated to obtain the required usage information.

[0167] Step 4334: If the end construction information or the end construction information is not in the construction continuity information, the demand and use information is formed based on the reconstruction replacement information and the continuous construction information.

[0168] If the last construction information or the last construction information is not in the construction continuity information, it means that there is no connection between the preceding and following information and they are not related constructions. Therefore, the demand and use information is formed by combining the reconstruction and replacement information with the continuous construction information.

[0169] The methods for obtaining information on the intended use of the information also include:

[0170] Step 45: Obtain historical land information.

[0171] Historical land information refers to data related to the target land's past land use status, construction, land use change records, and actual usage. This historical land information is obtained by storing data from each land adjustment and actual usage. When specific land use information is needed, the system extracts the target land's historical construction records, land use change information, and usage status data to obtain the historical land information.

[0172] Step 46: Sort the historical land information according to the preset time rules to obtain the historical ranking.

[0173] The time rule refers to the criteria for organizing and sorting historical land information chronologically. This time rule is set by professionals in this field based on actual time and input into the system. Historical sorting refers to the ordered data sequence formed by arranging historical land information chronologically according to the time rule. This historical sorting is obtained by the system arranging historical land information sequentially according to the time rule.

[0174] Step 47: Output historical land information sequentially based on historical sorting and analyze it to obtain information on land changes.

[0175] Land change refers to the changes and development trends in land use, construction status, utilization methods, and functions of a target land site over different historical periods. The analysis of land change here involves the system comparing land use status, construction content, and use change data period by period based on historical land information sorted by time, thus identifying the content and trends of land changes at different stages.

[0176] Step 48: Calculate and predict land information based on land changes.

[0177] Predictive land information refers to information on the potential future land use trends, construction demands, and changes in land use status, obtained through analysis and extrapolation based on historical land changes. The calculation method for this predictive land information involves the system fitting and extrapolating future land use patterns and trends reflected in land changes to obtain predicted land-related information.

[0178] Step 49: Extract the predicted land use information from the predicted land information, define it as demand use information, and output it.

[0179] Predicted land use information refers to the potential future land use, construction direction, and functional planning information. This information is extracted by the system from predicted land information calculated based on historical trends, filtering and extracting content related to the subsequent planned land use and construction functions to form the predicted land use information.

[0180] The methods for adjusting actual usage information based on demand and purpose information to obtain updated adjustment information and then outputting it include:

[0181] Step 60: Find the corresponding set of surrounding land information through the information of a single land parcel.

[0182] The surrounding land information set refers to the set of land information corresponding to the surrounding land parcels that spatially surround or enclose a single target land parcel. The method for finding this surrounding land information set is as follows: based on the spatial coordinates and boundary range of the single land parcel information, the system extracts information on all surrounding land parcels from the land adjustment information to obtain the surrounding land information set.

[0183] Step 61: Extract the surrounding use information from the surrounding land information set.

[0184] Enclosing land use information refers to information related to the current planned use, construction function, and actual use of each surrounding plot in the surrounding land information set. This information is extracted by the system from the surrounding land information set, specifically by extracting information on the planned use, construction function, and usage status of each surrounding plot.

[0185] Step 62: Combine the demand information with the surrounding demand information to obtain coherent demand information.

[0186] Coherent demand information refers to planning and construction information that connects the target land with surrounding plots in terms of function and use, ensuring a coherent fit. This coherent demand information is obtained by the system performing correlation analysis between the target land's demand and the uses of surrounding plots, extracting coherent planning content that connects the functions of the target land with its surrounding land.

[0187] Step 63: Adjust the actual usage information according to the coherent demand information to obtain updated adjustment information and output it.

[0188] The updated adjustment information is obtained by the system based on the coherent demand information, which adapts the actual use information of the target land to the function and adjusts the layout. This ensures that the use of the target land is consistent and unified with the use of the surrounding land, forming the adjusted land adjustment information. For example, if there is a residential area on this land, and the surrounding land is all roads, and the demand information indicates that the residential area needs to be connected to the road, then this is taken as the coherent demand information. Regardless of the specific construction location, as long as it is determined that a connecting road needs to be built, the actual use information is adjusted, and a road is arbitrarily selected to make the adjustment.
