Methodology and key technology of provincial information system of mine resources planning and management based on ArcGIS were discussed. Geographic Information System (GIS) is a comprehensive information technology capable to store, manage, analyze and display spatial data, and its powerful spatial query and spatial analysis function have been widely used in management of land resources. The regional GIS for mineral resources management has a 3-layered architecture, which are provincial, municipal, and county lever respectively. The informationization method of the mineral resources management was studied theoretically and practically. Spatial databases combined with graphic databases and attribute databases were established with ArcSDE, which is a database engine developed by the Environmental Systems Research Institute (ESRI). The interior table of the graphic database and the outside table of the attribute database are linked by the key fields. The graphic data together with the attribute data, can be stored, processed and analyzed in accordance. ArcGIS developed by ESRI was chosen as GIS development platform,and Oracle was chosen as database platform. The developing languages were Microsoft Visual Basic, VB.NET and Javascript. The developed system can support the functions of mineral resources management, data maintenance, data update, data share and data publishing. The development of the above mentioned system provided a successful scheme for the management of regional mine resources.
