Abstract:

It is a fundamental research to investigate or survey some key mining areas in West China for driving factors of land degradation therein. In order to solve the problem of how to store and share the data obtained in the surveys and investigations, it is essential to design an effective database management system. Based on features of the data already obtained during the surveys and investigations of the coal, metal and non-metal mining areas, the data to be acquired are characterized by enormity in volume, scatterness, diversity and confidentiality. The B/S structure presently in prevelance is chosen to meet the needs of users for uploading and storing data in a number of locations. Moreover, the background for data control adopts SSH+Tomcat, the mainstream frame of J2EE, to satisfy users' concurrency, and the accompanying ArcGIS Server and ArcEngine to process geographic data. This system is found to have the functions of user management, data uploading and downloading, documents online browsing, and geographic data online browsing etc., and hence is adequate to meet users' basic demand for examination and data sharing.
