白马湖周边农作物面源污染控制技术研究

面源污染受降雨、土壤类型、土地利用类型和地形条件等的影响,具有间歇性、地域性和不确定性,农村面源污染形成后,单纯依靠末端治理技术很难对其形成全面有效的控制。治标更要治本,对农村面源污染拟采用源头控制与末端治理相结合的措施,着重从农田面源污染控制方面对农村面源进行污染控制技术研究。开展了农作物面源污染控制研究,拟通过调整施肥模式,控制农作物所产生的污染负荷量,以达到保护白马湖水环境的目的。

Research on Non-Point Source Pollution Control Technology of the White Horse Lake Surrounding Crops

Non-point source （NPS） pollution is intermittent, regional and uncertain affected by the rainfall, soil, land use, and topography. When NPS pollution occurs in rural areas, it is difficult to control effectively if only the end-of-pipe （EOP） treatment is taken; thus, a method to tackling the root of the problem is in need. As a consequence, the combination of source control and EOP treatment is intended to serve as a way of controlling NPS pollution in the rural areas. This paper focuses on the research on the rural NPS pollution control technology in terms of the agricultural NPS pollution. The research was carried out by changing fertilization mode, thereby controlling the pollution load of crops as well as implementing the environmental protection of the White Horse Lake.
