[0013] The beneficial effects of this invention lie in acquiring multi-source data (such as geological surveys, topographic maps, climate, soil types, etc.) of land development areas, and processing and analyzing the data of different areas to extract the geological characteristics of each area. This process helps identify the geological conditions of different areas, including important characteristics such as stratigraphic composition, soil and rock types, and groundwater distribution, providing accurate basic data support for subsequent risk assessment and planning design. Through the comprehensive processing of multi-source data, a more comprehensive understanding of the natural conditions of the development area can be achieved, improving the scientific nature and accuracy of land development. By acquiring land development planning data (such as development purpose, construction density, development methods, etc.), combined with the aforementioned geological characteristic data, the risk of geological change and structural instability in different areas can be predicted. By simulating changes in geological structure, the occurrence of structural instability phenomena is assessed, providing risk warnings for development projects. Subsequently, based on the geological change and structural instability risk data, further risk simulation of groundwater infiltration changes is conducted, thereby assessing the potential impact of groundwater flow and soil infiltration characteristics on the development area. This module effectively realizes risk assessment in the land development process, helping decision-makers identify and avoid potential risks during the planning stage. Based on groundwater seepage risk data, multi-objective scenario fitting technology is used to construct geological risk fitting data under different development scenarios. This fitting data reflects risk changes occurring under various development models and geological conditions. Next, a land development risk early warning model is constructed using this data to provide early warning and prediction of potential geological risks, groundwater changes, and their impact on land development. This module provides a comprehensive and accurate risk prediction model for land development projects, enabling developers to take corresponding preventative measures in advance, effectively reducing or avoiding the impact of sudden geological risks on the project. The land development risk early warning model is transmitted to the control center for intelligent management and real-time monitoring of development information data. Through the intelligent management platform, decision-makers can view risk early warning information for land development areas at any time, understand the dynamic risks such as geological changes and groundwater flow in different areas, and adjust development plans and countermeasures in real time. The management execution module ensures the safety and controllability of the land development process by providing data analysis results and risk early warning information, providing scientific and efficient management support for development projects, and promoting the sustainable development of land development and the rational use of resources. Therefore, this invention is an optimization of a traditional intelligent management system for land development information based on multi-source data. It solves the problem that the traditional intelligent management system for land development information based on multi-source data does not accurately identify geological risks in the development process, thus failing to conduct accurate land development risk early warning management. It improves the accuracy of geological risk identification in the development process, enhances the early warning capability for land development risks, and strengthens management capabilities.

Detailed Implementation
[0015] Please see Figures 1 to 3 A land development information data intelligent management system based on multi-source data includes the following modules: The land geological feature extraction module is used to acquire multi-source data of land development areas; based on the multi-source data of land development areas, geological features are extracted between different areas to obtain land geological feature data between different areas; The risk prediction module is used to acquire land development planning data; based on the land development planning data, it performs geological change and structural instability risk prediction on land geological characteristic data between different regions, and obtains geological change and structural instability risk data; based on the geological change and structural instability risk data, it performs groundwater seepage change risk simulation, and obtains groundwater seepage change risk data. The risk warning model construction module is used to fit multi-objective scenarios based on groundwater seepage change risk data to obtain geological development multi-objective scenario risk fitting data; and to construct a land development risk warning model based on the geological development multi-objective scenario risk fitting data to obtain the land development risk warning model. The management execution module is used to send the land development risk early warning model to the control center to perform intelligent management of development information data.
[0016] In this embodiment of the invention, reference Figure 1 The above is a schematic diagram of the module flow of a land development information data intelligent management system based on multi-source data according to the present invention. In this example, the land development information data intelligent management system based on multi-source data includes: S1: Land geological feature extraction module, used to acquire multi-source data of land development areas; based on the multi-source data of land development areas, geological features are extracted between different areas to obtain land geological feature data between different areas; In this embodiment of the invention, multi-source data of the land development area is acquired. The data sources include satellite remote sensing images, geological survey data, groundwater monitoring data, meteorological data, and regional historical geological disaster records. All of these data are processed in a standardized format to ensure that various types of data can be uniformly formatted for subsequent analysis. Data cleaning tools are used to denoise the raw data, removing unnecessary noise signals and outliers. Subsequently, the data is divided into regions. Based on Geographic Information System (GIS) technology, a spatial positioning-based zoning method is adopted to divide the land development area into several sub-regions according to topography, soil type, and hydrological conditions. The geological feature data of each sub-region is processed separately. The cleaned data is analyzed at multiple scales, from microscopic geological layers to macroscopic surface structure. Combined with multimodal data processing technology, geological feature data of different regions, such as stratigraphic structure, soil type, and surface morphology, are extracted. Finally, land geological feature data of each region is obtained. The data includes, but is not limited to, parameters such as soil viscosity, soil layer distribution, rock hardness, and groundwater flow characteristics. These data provide an important basis for subsequent geological risk assessment.
[0017] S2: Risk prediction module, used to acquire land development planning data; based on land development planning data, perform geological change and structural instability risk prediction on land geological characteristic data between different regions, and obtain geological change and structural instability risk data; perform groundwater seepage change risk simulation based on geological change and structural instability risk data, and obtain groundwater seepage change risk data. In this embodiment of the invention, when acquiring land development planning data, the land use planning layer of the development area is first imported into the data processing system. This layer typically includes information such as land development direction, building density, soil improvement measures, road and infrastructure layout. This planning data is cross-analyzed with specific development areas to deduce the development change requirements for each area, especially the changes in soil and surface. By analyzing the impact of land development on geological structure, and based on existing geological feature data, theoretical simulations of geological changes are performed for each area. Numerical simulation techniques, such as finite element analysis (FEM), are used to simulate the topographic changes in the developed area, obtaining data on the risk of geological structural instability during land development. Using this data, combined with groundwater monitoring data, groundwater infiltration changes are simulated through a hydrodynamic model. Considering the changes in hydrological conditions after land development, the infiltration changes of groundwater under different geological conditions are analyzed, and groundwater infiltration change risk data are generated to further determine the infiltration problems caused by groundwater, such as groundwater level rise or water flow shear effect.
[0018] S3: Risk warning model construction module, used to fit multi-objective scenarios based on groundwater seepage change risk data to obtain geological development multi-objective scenario risk fitting data; and to construct a land development risk warning model based on the geological development multi-objective scenario risk fitting data to obtain the land development risk warning model. In this embodiment of the invention, based on groundwater seepage change risk data, data normalization is first performed, and convolution operations are used to smooth the data to reduce noise interference. Then, multi-objective scenario fitting is performed, integrating risk data from different regions into the same model framework. Multi-objective optimization methods in machine learning algorithms, such as Support Vector Machine (SVM) or neural networks (ANN) in deep learning, are used to identify risk factors in different scenarios. Through these techniques, the various risk data are weighted and summed to form multi-objective risk fitting data, which reflects the impact of multiple variables on land development risks. Based on this multi-objective risk fitting data, a land development risk early warning model is constructed using the policy gradient algorithm or particle swarm optimization algorithm (PSO). The model identifies potential risks in the development process by weightedly evaluating risk factors under different scenarios, ultimately generating a land development risk early warning model to provide decision support for development management. During the model construction process, multiple iterations of optimization are performed on each objective data to ensure the model's accuracy and generalization ability, and to ensure its effectiveness under different development scenarios.
[0019] S4: Management Execution Module, used to send the land development risk early warning model to the control center to perform intelligent management of development information data.
[0020] In this embodiment of the invention, the constructed land development risk early warning model is sent to the control center. The control center monitors and schedules land development in real time through an intelligent data management system. First, the control center obtains real-time data of the land development site, such as soil moisture, groundwater level, and meteorological conditions, by accessing a remote monitoring system. This data is then matched with the early warning model. Based on the judgment of the early warning model, the risks generated during the development process are assessed in real time. If the early warning model identifies potential geological or hydrological risks, the control center immediately initiates an emergency response procedure and mobilizes on-site resources for processing. The control center automates the management of various information within the development area through an integrated intelligent management platform, such as automatically adjusting development plans and optimizing soil and hydrological condition improvement measures in real time. This intelligent management process can improve the efficiency of land development and reduce risks caused by uncontrollable factors such as geological changes. Finally, through big data analysis technology, the monitoring system regularly updates the early warning model, ensuring that the land development management process is always kept in an optimal state of risk control.
[0021] The land geological feature extraction module includes: Obtain multi-source data on land development areas; Multi-source data cleaning is performed on multi-source data of land development areas to obtain cleaned land development area data. Regional land topographic structure analysis was performed on the cleaned data of land development areas to obtain regional land topographic structure data. Based on multi-source data of land development areas, geological features of different regions are extracted from regional land topographic structure data to obtain land geological feature data of different regions.
[0022] In this embodiment of the invention, when acquiring multi-source data for a land development area, geological survey data, satellite remote sensing images, meteorological data, surface hydrological data, and groundwater monitoring data are first obtained from different data sources. These data come from different remote sensing satellite systems, geological survey institutions, meteorological stations, and environmental monitoring stations. All data are stored in a standardized format during acquisition to ensure data consistency and comparability. Satellite remote sensing images are acquired by high-resolution remote sensing satellites, and the captured images are matched with geographic coordinates in a Geographic Information System (GIS). Geological survey data, including soil samples, rock strata data, and groundwater level monitoring data, are collected by a professional geological exploration team within the development area. Groundwater monitoring data is obtained by deploying groundwater monitoring wells and using sensors to continuously record changes in groundwater levels. Meteorological data, including precipitation, temperature, humidity, and wind speed, is obtained from nearby meteorological stations. After data cleaning and preprocessing, these data are stored in a unified database to ensure the timeliness and accuracy of the data. Furthermore, all data needs to be integrated with the GIS platform to facilitate subsequent spatial analysis and data mining. When performing multi-source data cleaning, the first step is to use data cleaning tools (such as the Pandas library in Python) to convert various types of multi-source data (such as remote sensing images, geological survey data, meteorological data, etc.) into a unified format to ensure that the data is synchronized in terms of time axis and spatial coordinates. Data with null or inconsistent values are filled or deleted. Specifically, interpolation algorithms (such as Lagrange interpolation) are used to complete missing data, and extreme outliers or significantly biased values are removed. Anomaly detection algorithms based on machine learning (such as the Isolation Forest algorithm) are used to automatically detect and eliminate noise signals. Data from different sources are standardized, and values from different data sources are converted to a unified unit to ensure data compatibility. The cleaned data generates land development area cleaned data, which includes all processed geological data, remote sensing data, meteorological data, groundwater monitoring data, etc. In subsequent steps, this cleaned data will be used as the basis for more in-depth analysis.When conducting regional land topographic structure analysis on cleaned data of land development areas, the first step is to input the cleaned multi-source data into the spatial analysis module using a GIS platform. Digital Elevation Model (DEM) data is then used for topographic analysis, extracting features such as topographic relief, slope, and elevation changes. Slope analysis reveals the slope distribution within the region, highlighting its significant impact on geological stability; areas with steeper slopes pose a risk of geological disasters. Next, a hydrological analysis model, combined with topographic and hydrological data analysis, yields information on water flow distribution and groundwater flow paths within the region. This allows for the assessment of drainage characteristics and groundwater level changes in the land development area. Regional water flow analysis is conducted using hydrological models (such as the SWAT model) to analyze groundwater permeability and the resulting land subsidence. Combined with surface image data, image classification techniques are used to analyze soil type and surface vegetation distribution. Finally, the above analysis results are integrated to generate regional land topographic structure data. This data encompasses the region's topographic relief, slope, soil type, and hydrological characteristics, providing a data foundation for subsequent geological feature extraction and risk assessment. Based on multi-source data and regional land topography data of land development areas, when extracting geological features between different areas, the development area is first divided into several sub-regions with similar geological features using clustering analysis methods (such as K-means clustering algorithm). This process is based on the distribution characteristics of land topography data. The development area is divided into multiple sub-regions according to factors such as topography, soil type, and groundwater characteristics. On this basis, the data of each sub-region is analyzed in depth. The geological stability of each region is assessed through geomechanical models. The soil and rock layers of different regions are simulated using the finite element analysis (FEM) method to extract the geological feature data of each region, such as soil compressibility, rock compressive strength, and groundwater permeability. Through multiple regression analysis, the quantitative characteristics of the impact of regional geological differences on development are further extracted. Based on these data, land geological feature data between different regions are obtained, including important parameters such as geological stability, groundwater level change trend, and soil type of each sub-region. Finally, regional land geological feature data is generated to support subsequent risk prediction and management.
[0023] The risk prediction module includes: Obtain land development planning data; Based on land development planning data, theoretical topographic change demand analysis was conducted on land geological characteristic data of different regions to obtain theoretical topographic change data for land development. Based on the land development topographic theory change data, the geological geological feature data of different regions are used to predict the risk of geological change and structural instability, and the geological change and structural instability risk data are obtained. Based on the geological change and structural instability risk data, a groundwater seepage change risk simulation was conducted to obtain groundwater seepage change risk data.
[0024] As an example of the present invention, reference is made to Figure 2 As shown, Figure 1 A functional flowchart of the medium-risk prediction module is shown in this example. The functions of the risk prediction module include: S201: Obtain land development planning data; In this embodiment of the invention, the latest land development planning documents are obtained from publicly available websites. These planning documents include land use patterns, land development sequence, project distribution, land development density, and infrastructure construction plans required for development. This planning data is provided in electronic format and contains detailed information and spatial distribution of land parcels. To ensure the timeliness and accuracy of the data, it needs to be updated regularly. Spatial positioning of the planning data is performed using a Geographic Information System (GIS), and spatial visualization of the planning data is achieved using spatial analysis functions. Each land development project is marked with its geographical location and overlaid with land development area data in the GIS. Version control is implemented for planning data from different periods to ensure that the latest land development planning data is accurately applied. The obtained land development planning data is stored in a unified database, where the data is tagged for efficient association between development data and geological data, providing data support for subsequent risk prediction.
[0025] S202: Based on land development planning data, conduct theoretical topographic change demand analysis on land geological characteristic data of different regions to obtain theoretical change data of land development topography; In this embodiment of the invention, when conducting theoretical topographic change demand analysis on land geological feature data of different regions based on land development planning data, the topographic change requirements related to land development are first extracted from the land development planning data. These include development activities such as earthwork excavation, backfilling, and road construction. By analyzing the impact of these activities on the topographic structure, a topographic change analysis model is used to simulate each development area. In specific operation, combined with the geological feature data of the region, numerical simulation methods (such as finite element analysis) are used to model different development activities. The topographic change process is decomposed into different units for calculation, and the topographic changes of each unit are estimated. The analysis of how these topographic changes affect the geological structure, such as soil compaction, rock strata subsidence, and changes in groundwater flow paths, is performed to obtain theoretical topographic change data for each region. In this process, the numerical simulation software used (such as ABAQUS or PLAXIS) can accurately simulate the specific impact of different development methods on the land and dynamically predict the changed topography. Finally, theoretical topographic change data of land development is output. This data includes the estimated changes in regional topography, soil, and groundwater caused by different development activities, which can provide a theoretical basis for subsequent risk prediction.
[0026] S203: Based on the land development topographic theory change data, predict the geological change structural instability risk of land geological feature data between different regions, and obtain geological change structural instability risk data; In this embodiment of the invention, when predicting the risk of geological change structure instability, the key factors leading to geological changes, such as soil structure, groundwater level, and topographic slope, are first extracted by analyzing the theoretical data of land development and topographic changes. Modeling of land geological characteristics in different areas is then performed, and the geological change structure is simulated using the finite element analysis (FEA) method. Based on geological survey data, soil physicochemical properties, and groundwater flow patterns, a complex geological change model is constructed. This model considers factors such as soil subsidence, groundwater infiltration, and earthquakes that occur during development. Specifically, the spatial analysis tools of ArcGIS software are first used to extract the geological characteristics of the land development area, such as stratigraphic structure and soil compressibility. By establishing soil mechanics and hydrogeological models, the geological characteristics of different development areas are calculated and simulated. Then, a three-dimensional numerical simulation is performed using specialized geomechanical calculation software (such as PLAXIS) to analyze problems such as soil instability and groundwater level changes that occur during development, obtaining geological change structure instability risk data. This data can predict whether different areas will experience geological disaster risks such as landslides and subsidence.
[0027] In another embodiment, a CSV file of land development topographic theory change data is loaded using Python tools. The file content is parsed to extract the coordinates and topographic change demand values for each cell. A CSV file of land geological characteristic data is also loaded to extract geological type, soil layer thickness, and lithological parameters. For example, if the geological type of a certain area is sandy clay, the soil layer thickness is 5 meters, the cohesion is 20 kPa, and the internal friction angle is 30°, the data is merged using Python's Pandas library, with cell coordinates as the merging condition, generating a merged dataset containing topographic change demand values and geological characteristic values. The NumPy library is then used to perform stratigraphic analysis on the merged dataset. Deformation structure analysis is performed by calculating the stress change in the strata based on the topographic change demand value. The stress change calculation uses an elasticity model with parameters including Young's modulus of 50 MPa and Poisson's ratio of 0.3. The results are stratum deformation structure data; for example, the stress change in a cell is 15 kPa, and the deformation is 0.02 mm. Based on this stratum deformation structure data, sequence loose viscosity structure analysis is performed on the soil layers. The analysis method involves calculating loose viscosity based on soil layer thickness and lithological parameters. The results are also presented as sequence loose viscosity structure data; for example, the loose viscosity in a cell is 0.35. Based on this sequence loose viscosity structure data, the internal friction angle loss due to external force intervention is estimated. The estimation method involves obtaining initial excavation force data (e.g., 10 kN), calculating the required matching excavation force values for different soil structures (e.g., 8 kN for sandy clay), calculating the average cohesion difference for each soil type (e.g., 5 kPa), simulating cohesive shear dilatation lateral pressure fluctuations based on the matching values and average differences (e.g., lateral pressure fluctuation data, 3 kPa), performing nonlinear shear friction stress analysis based on the fluctuation data (e.g., nonlinear shear friction stress data, 12 kPa), and calculating the internal friction angle loss due to external force intervention (e.g., 5°) based on the fluctuation and stress data. The bearing capacity ultimate limit of the foundation soil layer is simulated using angular loss data based on Terzaghi bearing capacity theory. Parameters include an internal friction angular loss of 5° and cohesion of 20 kPa. The calculation result is the bearing capacity ultimate limit data of the foundation soil layer, for example, a bearing capacity ultimate limit of 150 kPa. The risk of structural instability due to geological changes is predicted by combining the bearing capacity ultimate limit data, internal friction angular loss data, and loose viscosity structure data. The prediction method is based on a weighted scoring model, with weighting coefficients of 0.4 for bearing capacity ultimate limit, 0.3 for internal friction angular loss, and 0.3 for loose viscosity. The calculation result is the risk data of structural instability due to geological changes, for example, a risk value of 0.65 for a certain cell. S204: Based on the geological change and structural instability risk data, groundwater seepage change risk simulation is performed to obtain groundwater seepage change risk data.
[0028] In this embodiment of the invention, a Python tool is used to load a CSV file containing geological change and structural instability risk data. The file content is parsed, and the coordinates and risk values of each cell are extracted. Groundwater distribution data for the development area is also loaded. The data format is NetCDF and includes groundwater level depth and permeability coefficient. For example, the groundwater level depth in a certain area is 2 meters, and the permeability coefficient is 1×10^-5. The data is analyzed using Python's Xarray library to parse NetCDF files at speeds of m / s, extracting groundwater distribution data. Geological layer variability analysis is then performed on the geological change and structural instability risk data. The analysis method involves calculating the coefficient of variation based on risk values. The results represent the geological layer variability structure data; for example, a cell might have a coefficient of variation of 0.25. Based on this variability structure data, a relative weak value interval assessment is conducted. The assessment method involves dividing intervals based on the coefficient of variation; for example, intervals with a coefficient of variation greater than 0.2 are considered relatively weak intervals. The assessment results represent the relative weak value intervals of the geological layer; for example, a certain area might have a weak interval of 0.2 to 0.3. Finally, based on the groundwater distribution data of the development area, a shear moment imbalance calculation is performed on the weak intervals. The calculation method involves calculating the shear moment based on the permeability coefficient and groundwater level depth; for example, a permeability coefficient of 1 × 10^-5... The groundwater level is 2 meters deep, and the calculated results are the shear pressure moment imbalance data of the water flow. For example, the imbalance value is 8 kPa. Based on the imbalance data, a groundwater seepage change risk simulation is performed using the finite difference method. The grid resolution is 5 meters × 5 meters, and the time step is 1 hour. The simulation results are groundwater seepage change risk data, for example, the risk value of a certain cell is 0.55. The prediction of geological change and structural instability risk based on land geological characteristic data of different regions using land development topographic theory change data includes: Based on the land development topography theory change data, the stratigraphic deformation structure analysis was carried out on the land geological feature data of different regions to obtain the stratigraphic deformation structure data of different regions. Sequence loose viscosity structure analysis of soil layers was performed on the stratigraphic deformation structure data of different regions to obtain the sequence loose viscosity structure data of soil layers. Based on the sequence loose viscosity structure data of soil layers, the internal friction angle loss under external force intervention is estimated to obtain the data of internal friction angle loss under external force intervention. The ultimate bearing capacity of the foundation soil layer is simulated and calculated based on the loss data of the internal friction angle caused by external force intervention, and the ultimate bearing capacity data of the foundation soil layer is obtained. Based on the ultimate bearing capacity data of foundation soil, the internal friction angle loss data of external force intervention, and the sequence loose viscosity structure data of soil layers, the risk of structural instability due to geological changes is predicted, and the risk data of structural instability due to geological changes is obtained.
[0029] In this embodiment of the invention, the coordinates and topographic change requirement values of each cell are extracted, with a data resolution of 10 meters × 10 meters.

An initial land development risk early warning model is constructed using Python's TensorFlow library. The model structure is a three-layer neural network with 5 input layer nodes, 64 hidden layer nodes, and 1 output layer node. The activation function is ReLU (Rectified Linear Unit). The model is trained based on a policy gradient algorithm with parameters including a learning rate of 0.001, a discount factor of 0.95, and 1000 iterations. The training process calculates the loss based on the sampling feature values and normalized values, with the loss ranging from 0.01 to 0.05.
