Research Status and Prospect on Influential Factors and Control Technology of Agricultural Non-Point Source Pollution: A Review
农业面源污染影响因子及控制技术的研究现状与展望

The severity of non-point source pollution has caused wide public concern all over the world, and non-point source pollution has become into one of the most active international study fields of water environment. Based on the brief introduction of the occurrence mechanisms and the characters of agricultural non-point source pollution, this paper firstly summarized the research status of the influential factors of agricultural non-point source pollution, which include land use type, crop cultivation, management of irrigation and fertilization, terrains and landforms, characteristics of climate and hydrology, soc-economic factors and so on, then described the latest research progresses on the control technology of agricultural non-point source pollution in recent years, which include the constructed wetland technology, pretank technology, buffer zone technology, water & soil conservation technology and agricultural & ecological engineering technology, finally put forward the research emphases of agricultural non-point source pollution in the future in accordance with China's actual situation.
