植被过滤带的定量计算方法

Quantitative calculation methods for vegetative filter strips.

植被过滤带(VFS)因其能有效地滞缓径流、沉降泥沙、控制非点源污染,在美国已作为重要的最佳管理措施(BMP)得到应用。本文在简述国外植被过滤带设计方面的有关研究和应用的基础上,重点介绍了3种典型的过滤带带宽的计算方法,并对其进行了比较与讨论。最后,指出了今后需进一步研究的问题。

Vegetative Filter Strips （VFS） is a main kind of Best Management Practices applied in USA, because of its effectiveness in stagnating runoff, depositing sediment and controlling non-point source pollution. At present, there are few studies on the quantitative design for VFS in China, This paper summarized the research and practice of VFS design, introduced and compared three typical calculation methods of VFS width, and discussed the existing problems and further research contents of VFS design.
