Designing and Applying of a Soil Database System of Nanchong District Based on GIS

As one of the most important regions in Sichuan Province for carrying out western exploitation,Nanchong District has great potential of synthetical exploitation of country resources with the core of soil resource.However,at present,the content of science and technology to exploit the resources is relatively low,and the level of agricultural information is not high in Nanchong District.Due to the low level of agricultural information,the exploitation of agricultural resource and the economy is limited,so it is urgent to develop the agricultural with new and high technology,especially to research and popularize agricultural expert system.Based on collection and investigation of a great deal of soil information,the paper studied the designing and applying of Nanchong District soil database system with the support of GIS and the validation of the parallel analysis on the experimentation,established the soil database system of Nanchong District based on GIS for the first time,put forward the principle,means and patterns of establishing district level soil database system and the technic cource of popularizing and applying.
