The treatment and control of non  point source (NPS) pollution is a key factor which affects new countryside construction and society sustainable development. Introducing RS, GIS and GPS into research field of agriculture NPS pollution can prompt the development of agriculture NPS pollution monitoring system. Using this system, environment pollution can be dynamically effectively monitored and the spatial attribute information of agriculture NPS pollution can be managed scientifically. This information monitoring system, based on spatial information technology, can provide effectively assistant decision information for treatment of agriculture NPS pollution and environment. It can also help government make a correct and scientific decision.
