A Study On The Database System Of The Country Land Use Overall Planning Based On GIS

With the Land use Overall Planning of Wuming County, Guangxi District as the study background, according to the theory and methods of system engineering and software engineering, and with the technology of GIS and Database as its supports, this paper analyzed and studied the database about the County Land Use Overall Planning. The County Land Use Overall Planning Database system based on GIS was designed, which makes the Land Use Overall Planning more convenient, scientific and practical.The Database modeling approach of IDEF1X that bases on the relation model is employed in the system design. The module formula GIS that bases on the flat of object module is applied to insert the five important widgets of SuperMap Objects 2003 into the C# exploitation flat to explore. The space and attribute data are saved in SQL Sever in unites. In order to realize the dynamic renewal and various query of the earth nature data, the technology of GIS is used to realize the exchange visits between the attribute data and space data. The Database system was applied in the Wuming County Land Use Overall Planning and has acquired preferable effect. It offers the digitalized data of land resources for the land planning and management bureau of Wuming County and realizes the popularization of the Database system of Land Use Overall Planning as well.
