Description

Technical Field

[0001] This invention belongs to the field of natural resource database construction technology, specifically relating to a method for constructing a three-dimensional spatiotemporal database of natural resources. Background Technology

[0002] Internationally, natural resource asset accounting began in the latter half of the 19th century. In the 1970s, the United Nations University (SCEP) first proposed the concept of ecosystem service functions in its "Report on Human Impact on the Global Environment." In 1972, the United States established the National Natural Resources Survey (NRS), dedicated to investigating and assessing national natural resource assets. Using field sampling surveys and statistical methods, the NRS investigated and accounted for national natural resource assets, publishing the results every five years, thus promoting ecological environment construction throughout the United States. Subsequently, Holder et al. and Westmen et al. conducted research on global ecosystem service functions, pointing out that biodiversity loss directly affects ecosystem service functions. This led to the development of the concept of natural resource asset valuation and a series of studies on the classification of natural resource accounting items.

[0003] From the perspective of natural resource data management, the three-dimensional spatiotemporal database of natural resources is an iterative upgrade of the current natural resource data management and application models. It reconstructs the existing data management model from the perspectives of space, time and application, and is a brand-new exploration of data management and data application. Therefore, we tend to think that the three-dimensional spatiotemporal database is a standard and technical model. Its construction is based on the three-dimensional spatial framework of Real Scene 3D China. Reflected in natural resource surveys and monitoring, it constitutes the three-dimensional spatiotemporal database for natural resource surveys and monitoring.

[0004] Natural resource data is characterized by large volume, uneven spatial distribution, and constant change. Interoperability and data updates between the main database and various sub-databases of the three-dimensional spatiotemporal database of natural resources are difficult. Therefore, a method for constructing a three-dimensional spatiotemporal database of natural resources is proposed. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a method for constructing a three-dimensional spatiotemporal database of natural resources, which solves the difficulties in data exchange and updating between the main database and various sub-databases.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for constructing a three-dimensional spatiotemporal database of natural resources, comprising the following steps:

[0007] Step 1: Overall Planning. To meet the needs of unified, three-dimensional management of various natural resource survey and monitoring data, a comprehensive design of the main database will be undertaken, standardizing database content, models, interfaces, and other specifications. Based on the progress of each sub-database construction, integration and sharing will proceed as each database matures, steadily advancing the construction of the three-dimensional spatiotemporal main database for natural resources, while simultaneously guiding the construction of local databases at all levels.

[0008] Step 2: Database Model Construction: Based on the three-dimensional layered architecture of surface cover layer, surface matrix layer, underground resource layer, and management layer, three-dimensional management is achieved through entity expression modeling, time phasing is achieved through spatiotemporal evolution modeling, location partitioning is achieved through spatial grid coding, and business semantic relationship modeling is used to establish spatial semantic associations between entities and the "Third National Land Survey" base plate, as well as business logical associations between entities, ultimately constructing a three-dimensional spatiotemporal data model of natural resources.

[0009] Step 3: Database Logical Integration: The main database and each sub-database are physically distributed across their respective construction units. With a unified service interface and interconnected network links, the main database directly calls the data services of the sub-databases. Once relevant conditions are met, the main database can directly call local databases at all levels. As a component of the "One Map" system for natural resources, the main database supports access to the national land spatial information platform.

[0010] Step Four: Three-Dimensional Management and Updates: In the development of the database management system, advanced technologies such as cloud architecture and three-dimensional spatial data visualization are fully utilized to improve the efficiency of rapid information processing and massive storage access, better ensuring the efficient operation of the database. Simultaneously, big data mining, cloud computing, and other technologies support the statistical analysis and evaluation of natural resource survey and monitoring results, providing support for land spatial planning, land use control, protection and restoration, real-time updates, development and utilization, and supervision and enforcement.

[0011] Preferably, the overall planning in step one also includes a comprehensive survey of natural resource survey and monitoring data resources, a systematic review of the comprehensive business needs of national-level natural resource management, and the design of the main database content system. This includes surveying the current status and data results of various natural resource surveys and monitoring, collecting relevant technical specifications and data result examples, and conducting analyses of data content, three-dimensional features, attributes, accuracy, indicators, and data formats; surveying the specific business needs of relevant departments of the Ministry of Natural Resources regarding natural resource management, and reviewing the support requirements for data content, multi-thematic integration, and analysis and evaluation models in a three-dimensional environment.

[0012] Preferably, the overall planning in step one also includes systematically sorting out various natural resources such as land, minerals, forests, grasslands, wetlands, water, sea areas and islands, and corresponding to a four-layer investigation and monitoring system of underground resource layer, surface matrix layer, surface cover layer and management layer, and comprehensively designing the content, indicators, codes, attributes, and layers of the main database to form the main database content system.

[0013] Preferably, the specific method for building the database model in step two is to conduct data fusion and database construction based on a unified content system and model design, using structural reorganization and correlation fusion. Based on the unified database content and model design, multi-scale, multi-granularity, and multi-temporal data from various natural resource surveys and monitoring are reconstructed and reorganized to uniformly construct natural resource entities.

[0014] Preferably, in step two, the database model is built by utilizing real-time image publishing technology combined with vector tile scheduling, based on service aggregation, to integrate and share massive amounts of multi-source heterogeneous data. Following a unified service interface specification, 3D entity data of natural resources is published using a general 3D service standard, 2D entity data of natural resources is published using a vector tile standard, and survey and monitoring image data is published using a combination of dynamic tile-free and static tile methods. Finally, with network connectivity, service aggregation is used to achieve both physical distribution and logical integration between the main database and the nine sub-databases.

[0015] Preferably, the platform for building the database model in step two relies on an independently controllable domestic 3D system platform to carry out the research and development of the database management system. Priority is given to using an independently controllable domestic 3D system platform, employing 3D entity management and 3D visualization as means, and utilizing distributed database technology to construct a natural resource 3D spatiotemporal master database management system composed of an online application subsystem, a professional management subsystem, a service publishing subsystem, and an operation and maintenance supervision subsystem.

[0016] Preferably, in step four, the three-dimensional management technology of the main database management system adopts a unified architecture, business collaboration, and information linkage overall framework. The system architecture is divided into infrastructure layer, data layer, service layer, and application layer. The management system is mainly used for the establishment, operation, management, and maintenance of the three-dimensional spatiotemporal main database of natural resources, providing unified and standardized data and operation service interfaces, realizing integrated storage management, browsing and querying, statistical analysis, and application of results of natural resource survey and monitoring data, realizing the integration of survey and monitoring data with natural geography, socio-economic, and other data, and supporting the decision-making related to natural resource management.

[0017] Preferably, the operation service supports operations such as adding, modifying, querying, and deleting entity data, and fully leverages the computing advantages of distributed databases and database cloud platforms to improve the efficiency of entity operation and management of hundreds of millions of spatial data.

[0018] Preferably, the data interface supports data entity distribution, interface access, data filtering, data extraction, data export, and other distribution operations, and is compatible with common exchange formats such as 3D data, vector data, raster data, tabular data, and file data.

[0019] Preferably, the three-dimensional management also includes system security monitoring, which should support comprehensive monitoring of hardware security, data security, link security, application security, user permissions, traffic control, etc., and support access authorization and security management for multiple scenarios such as data, network, departments, users, and applications.
