%X After analyses to spatial planning decision making requirements of agricultural non point source (AGNPS) pollution in the region of Hanjiang River watershed, we designed the structure, function and database of agricultural non point source pollution information system using the methods of integrating GIS integrated and remote sensing. At the end, the information system was developed. The system comprises of three subsystems: the spatial analysis and remotely sensed data processing system, the model management system and the statistics database management system. This system has multifunction with detailed spatial and attribute database including fundamental geographic elements, eco environment, landform, remotely sensed image and statistics data. Agricultural non point source pollution was then detected dynamically. Our integrated system provides a robust and user friendly environment for the standard three step management procedure of non point source pollution:(1)critical area identification. (2) Best Management Practices (BMPs) selection, and (3) comprehensive regional pollution control plan. It will be helpful for local government to make a feasible decision on this issu.
