Under the background of the natural resource asset management system, the land reserve has begun to take the step of transformation to natural resources, and strengthening the management of reserve land resources assets has become an important part of fulfilling the responsibilities of the owners of all natural resource assets owned by the whole people, and mastering the land reserve resources within the administrative jurisdiction has become an important matter for the local government and natural resource management departments. At the same time, how to integrate the whole process of land approval, reserve, and utilization of data information and digital technology means to realize the dynamic monitoring, intelligent extraction and management of land reserve information, and the intuitive interaction of visualization, help the development and utilization strategy of reserve land, and guide the development and construction of cities in an orderly manner, has become an urgent problem to be solved in the investigation of land reserve resources.
The author believes that in the context of natural resource asset management, it is urgent to carry out the investigation (mapping) of land reserve resources, conduct a detailed investigation of the quantity, quality, distribution, ownership, protection and development and utilization of reserve land, as well as economic value information, and realize the dynamic monitoring and whole-process management of land reserve information through informatization and construction platform.
part.Carry out special surveys (surveys) of land reserve resources
Based on the data of the third national land survey and other special survey data, carry out special investigation (mapping) of land reserve resources. It is mainly to investigate and sort out the basic information of the current situation of the reserve land (location, area, land use status, land ownership, ground attachments), land use approval information (land use approval, historical land use procedures), development and utilization information (early development, later management and utilization), storage information (storage time, compensation, storage area, storage purpose) and cost value information (storage cost, benchmark land price) and other relevant information.
Among them, for the plots that have been collected and stored and put into storage, it is mainly on the basis of the existing data and information to carry out supplementary investigation on the missing information;For the plots to be acquired and stored in the near future, it is necessary to carry out a comprehensive investigation and combing of the above information. By carrying out special investigation (mapping) of land reserve resources, it provides data support for filling in the land reserve monitoring and supervision system, as well as compiling land spatial planning, land reserve planning plan, and land reserve balance sheet.
part.Construct a "one map" of land reserves
Based on the results of the special investigation (mapping) of land reserve resources, the basic information of the reserve land is comprehensively sorted out and optimized, the vector information of the reserve plot is sorted out and summarized, the land reserve database is established, and the "one map" of land reserve is constructed. Among them, the key development areas determined by the territorial spatial planning will be included in the land reserve plan, and the plots to be acquired and stored in the past three or five years can be integrated and formed"One map" for land reserve planning
For the plots included in the annual land reserve plan, the land reserve plan can be integrated to form a "one map" and included in the land reserve information management platform. Through the construction of "one map" of land reserve, the intelligent extraction and management of land reserve information and dynamic monitoring are realized, which provides data support for the formulation of reserve land development and utilization strategies, guides the layout of land reserve to key urban development areas, promotes the optimization of urban spatial structure, and helps the modernization of land space governance.
part.Deepen the application of land reserve data
On the one handBased on the data services and functional services of the land reserve monitoring and supervision system, establish a land reserve information sharing mechanism, promote the management, sharing and distribution of land reserve information at the city and county levels, and realize the sharing and service of land reserve information resources in the city.
On the other handStrengthen the linkage between the land reserve monitoring and supervision system and the basic information platform of land space, the supervision information system for the implementation of the "one map" of land spatial planning, and other business systems of natural resources, and carry out the application of land reserve data results in multiple dimensions. For example, it can integrate professional basic data such as benchmark land price, overall land space planning, and detailed planning, as well as data on population, economy, transportation, and public service facilities. Construct an intelligent decision-making model for land reserve (such as the first model of storage cost, the first model of transfer, and the analysis model of reserve balance) to serve the value evaluation of reserve plots, and provide reference for the implementation of compensation, land transfer, and preparation of land reserve balance sheets.
