滨岸缓冲带去除农业面源污染技术研究

Technical Research of Riparian Buffer in Removing Agricultural Non-Point Source Pollution

农田面源氮、磷的流失是导致河流湖泊等水体产生富营养化的主要原因之一,滨岸缓冲带能够有效地防治农业面源污染已经得到了广泛的认可,并在保护水体方面有一定的应用前景。介绍了缓冲带的定义、结构、功能及控制要素,提出了滨岸缓冲带去除农业面源污染技术在我国的应用前景。

Losses of nitrogen and phosphorus from agricuhural fields are one of the major factors responsible for eutrophication of lakes and rivers. Riparian buffer zone which could prevent and control agricultural nonpoint source pollution effectively, has been widely recognized, and it also has a certain application prospecl on the source of water prevention. This paper introduces the definition, structure, function and controlling factors of the buffer zone, and puts forward the application prospect of the riparian buffer zone to remove the agricultural non-point source pollution in China.
