Description

Sea island multidimensional adaptation method and system based on space topology and semantic mining Technical Field The invention belongs to the technical field of ocean resource management and homeland space planning, and particularly relates to a sea island multidimensional adaptation method and system based on space topology and semantic mining. Background Sea island project management is used as a core link of sea resource management and homeland space planning, and is dependent on traditional informatization means and manual operation flow for a long time. The prior art mainly reports, reviews and counts projects around a decentralized business system or paper report, but exposes significant limitations in practical applications. First, at the data management level, the prior art lacks a unified standard specification, resulting in data dispersion and heterogeneous problems. When the city and county primary units report the island project for sea, custom table format or unstructured documents are often adopted, and field definitions are different, for example, hectare, mu or approval state expressions can be mixed by sea area units. The phenomenon of data fragmentation makes it difficult for a provincial management department to realize transverse comparison and summary statistics, so that not only is the labor cost of data cleaning increased, but also statistical errors are easily caused. Secondly, at the examination flow level, the prior art excessively relies on manual intervention, and is low in efficiency and prone to error. Planning compliance, ecologically protecting red line, natural shoreline occupation and other key inspection links, and usually, operators need to manually superimpose GIS layers for visual judgment. This process is not only time consuming, but also results in missing sensitive areas due to manual fatigue or experience inadequacies. Finally, in the system design level, the prior art has the disadvantages of service and space analysis of splitting and poor user experience. Most systems separate the "business fill" from the "spatial analysis" module, and users need to switch among multiple interfaces, and cannot instantly know whether the project involves a sensitive area or not during fill. Such disjointing not only prolongs the approval period, but also increases the risk of reworking the project due to feedback lag. In summary, the existing island project management technology for sea cannot meet the requirements of scientific configuration and fine management and control of sea resources due to insufficient data standardization, low efficiency of manual inspection and service space dislocation. There is a need for an innovative solution that integrates, automates, and supports multidimensional adaptation to improve management efficiency and decision accuracy. The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. Disclosure of Invention The invention aims to provide a marine island multidimensional adaptation method and system based on space topology and semantic mining, which can solve the problems of insufficient data standardization, low efficiency of manual examination and service space disjoint in the existing marine island project management technology. To achieve the above object, a first aspect of the present invention provides a marine island multidimensional adaptation method based on spatial topology and semantic mining, comprising the steps of: Receiving structured information input of three items of sea, island and sea island; Carrying out combined query based on a plurality of conditions in county level administrative division, project names, industries, approval levels/modes, whether approval is completed or not and demand years, and dynamically displaying a query result list; According to the county administrative division field of the project, automatically distributing the project to be issued to the corresponding county user account, and synchronizing the project states in the same county unit, wherein the project states comprise temporary storage and submitted states; automatically calling GIS service on the project detail page, superposing a plurality of geographic information layers for space topology analysis, and outputting a space topology analysis result; and automatically filling project information and a space topology analysis result based on a preset template to generate a PDF format analysis report. Optionally, the structured information includes applicant, construction content, sea/island type, mode, area, age, natural shoreline occupancy, whether an unbiased filled field is involved, and support uploading PDF approval files. Optionally, the geographic information layer includes a base geographi
