China and important to the socio-economy development of Anhui Non Point Source Pollution, Export Coefficient Methods, Chao Province. With the enforcement of agricultural development, Lake. agriculture planting and stock breeding sectors boosted quickly and None Point Source(NPS) Pollution has become a I. INTRODUCTION considerable source contributing to the total pollutants loads into Chao lake. It is essential to study NPS pollutants loading amounts NPS pollution is caused by rainfall or snowmelt moving and their spatial distribution for taking effective over and through the ground. As the runoff moves, it picks up countermeasures to control NPS pollution. It is a complex task to and carries natural and anthropogenic pollutants, finally estimate the contribution of different NPS sources in a large depositing them into lakes, rivers, wetlands, coastal waters and watershed like Chao lake. When there is no extensive pollutant ground water systems [1].
