Abstract :
The situation of agricultural non-point source (AGNPS) pollution in Wei River basin has been analyzed. AGNPS caused by the enrichment of nitrogen and phosphorus, the excessive usage of pesticides, herbicides, agricultural films and the random discharge of livestock waste and sewage from diffuse sources is degrading surface water quality throughout the watershed. The relevant measures and countermeasures have been put forward to prevent water body pollution, such as enhancing farmers´ awareness of environmental protection, adopting environmental economic means, establishing monitoring and evaluation system of AGNPS and improving related policies and laws.
