河湖滨岸缓冲带净污机理及适宜宽度研究进展

Research progresses in purification mechanism and fitting width of riparian buffer strip

  • 摘要: 在分析河湖滨岸缓冲带结构特征和定义的基础上,从3个方面阐述河湖滨岸缓冲带净化农业非点源污染物的机理:(1)降低地表径流速度,过滤和拦截颗粒态污染物;(2)植物吸收、土壤吸附溶解态的污染物;(3)促进氮的反硝化作用。论述了河湖滨岸缓冲带适宜宽度的研究进展,认为在我国仅仅从环境的角度对适宜宽度进行研究还远远不够,需要从环境、经济和社会等角度对河湖滨岸缓冲带的适宜宽度进行综合研究。探讨了河湖滨岸植被缓冲带净污机理需要进一步研究的突出问题。

     

    Abstract: Based on the analysis of the structure characteristics and definition of the riparian buffer strip,the primary mechanism to control the rural non-point pollution is discussed from the following aspects:(1) reducing the speed of surface runoff,filtrating and barring the particulate contamination; (2) assimilating dissoluble contamination by vegetable and soil; and (3) facilitating denitrification.Research progress in the fitting width of the riparian buffer strip is discussed,and a view is put forward that the study on the fitting width of the riparian buffer strip only from the point of environment is far from enough in China and the integrated study is necessary for the fitting width of the riparian buffer strip from the point of environment,economy,society,etc.In the end,the future progress in purification mechanism of the riparian buffer strip is prospected.
