摘  要：
农业面源污染物的排放已经成为湖泊与河流主要污染源之一,河岸植被缓冲带能沉积、吸收与截留污染物,减少面源污染物进入水体。河岸植被缓冲带减缓农业面源污染的效果与缓冲带宽度、植物种类、坡面坡度、土壤类型等因素有关,其中确定适宜河岸植被缓冲带宽度,以实现其净化面源污染成为研究热点。笔者综述了河岸植被缓冲带的不同表述、河岸植被缓冲带削减面源污染物的主要机理、影响因素、研究方法以及相关模型等方面的研究进展,针对目前研究现状,认为应进一步加强缓冲带宽度对河岸植被缓冲带削减面源污染物影响的量化研究,增加林分尺度、坡度平缓的河岸人工植被缓冲带的研究,以及对模型的优化研究。

摘  要：
Agricultural nonpoint source pollution has already been a major pollution of streams and lakes. There has been growing recognition of the importance of riparian vegetation buffer strip in controlling nonpoint source pollution from agricultural fields into the waters by sediment trapping,absorption and removal of pollutants. The alleviation efficiency of the buffer strips depends on many factors,such as buffer strip width,vegetation type,slope and soil type. Nowadays,the optimum width determination of riparian vegetation buffer for maximum pollutant purification is still one of the main research hotspots. This paper reviewed the concepts and terminologies related to riparian vegetation buffer strip,and then mechanisms,impact factors,research methods of the effects of riparian vegetation buffer strip on alleviating agricultural nonpoint source pollution especially in terms of buffer strip width,as well as the relevant model simulation. The further studies should focus on the quantitative effects of buffer widths of riparian vegetation buffer strips on the pollutant reduction,especially the field scale with slight or no slope,and the model optimization based on the calibration and validation of parameters.
