Research and Prospect on Non-point Pollution from Agriculture

As point source pollution discharge were controled and treatmented got better,non-point source pollution becomes an important reason of water pollution.Non-point source pollution is relatively speaking point about source pollution,it includes agricultural non-point source pollution and urban nonpoint source pollution,and we normally refers to the agricultural non-point source pollution.Because of its dispersion,concealment,randomicity,uncertainty,universality,hysteresis,fuzziness and not easy monitoring caused the difficulty of study and control.This paper introduces the definition of agricultural non-point source pollution and sources,characteristics,harm,and,this paper explains the research progress and control measures of agricultural non-point source pollution at home and abroad,and,agricultural non-point source pollution study is forecasted.
