Abstract
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.关键词
