Thus the water pollution there will directly affect the water quality of the Water Transferred. And Agricultural Non-point Source Pollution （ANPS）had found to be one of major pollute source in the reservoir area, controlling this kind of pollution, therefore is of great importance for ensuring the successful water diversion. Based on the conceptual Model of Pressure-State-Response （PSR）, the ANPS including pollutions by poultry and livestock breeding, soil erosion, chemical fertilizers loss, human excrements, domestic waste, straw wastes, aquaculture and rural domestic
