低影响开发(LID)植草沟技术研究进展

Research Progress on Low Impact Development(LID)Planting Ditch Technology

植草沟技术作为低影响开发措施之一,具有改善水质、输送和渗透雨水径流的作用。现从植草沟类型、净化作用和径流削减作用等三个方面,论述了国内外的主要研究进展,探讨了目前该技术研究存在的不足,并就该技术的发展方向进行了展望,以期为国内植草沟的进一步研究提供参考。

As one of the low-impact development measures,the plant grass ditch technology has the function of improving water quality,transporting and penetrating rainwater runoff.This paper discusses the d research progress from three aspects:the type of planting ditch,the purification effect and the reduction of runoff,and discusses the shortcomings of the current research.The development direction of the technology is prospected,in order to provides a reference to further research on ditch grass planting in China.
