The Study On Mineral Resources Management System Based On GIS--With The Sample Of Yulin District

"Digital land" project posed by National Land Resources Ministry in land and resource survey,is another information project after "digital earth".This indicates resource information management has been one of the important subjects in present science and technology fields.The mineral resources are an important part of national land resources.They are one of the most basic and important production data which the human beings rely on for existence and develope by.and also are the matter foundation of national economy and society development.Thefore,it's very significant to promote rationally developing and utilizing the mineral resources by changing the traditional management method,applying the modern information technology to establish the mineral resources management system.Geographic Information System is just a comprehensive information technology capable to store,manage,analyze and display spatial data,and its powerful spatial query and spatial analysis function have been used in both natural and social sciences,especially in the field of the national resources management.On GIS platform,the article studies the designment and development of the mineral resources management system in Yulin,and probes into an information method of the mineral resources management in theory and practice.Based on analyzing the requirements of the system's functions,the author establishes the two databases combined with:the graphic database and attribute database.And the author realizes the link between the interior table of the graphic database and the outside table of the attribute database by thekey field.So the graphic data is stored,disposed and analyzed corresponding with the attribute data,and the collected data of the mining area can be implemented with the information management.Based on MAPGIS 6.0 system development platform,using the API function and MFC which the platform supplies,with Microsoft Visual C++ 6.0, with the environment of the windows,the author developes the main function modules and its realization of the programming designment.Based on the above studies,the author successfully developes the mineral resources management system with the unit of county or city based on GIS.The system is integrated with the functions: attribute data management,graphic data management,information query,report output.The system is available with the sample of Yulin districts.It has the following properties:stable perfermance,simple operation,friendly interface and good convenience in use. Used in Mineral Resources Bureau of Yulin ,the system not only reaches the requirements of the daily resource mieral management and promotes greatly the management of the mineral resources and also has widely prospects in applications.
