In order to effectively manage the data from the project of west China eco-environment investigation, a Shaanxi Provincial Eco-environment Database System was designed and set up. This GIS based database system tones up the interface operation efficiency not only intuitively and flexibly, but also optimize the method of spatial data browsing and processing integrally. By means of a specially designed information searches program, this system can provide people with more valuable and comprehensive environment spatial distribution information. This research is of great significance both in theory and in practical applications.
