摘　　要：植被过滤带是一种控制非点源污染的新型生态工程措施。本研究在陕西小华山水库岸坡地按不同植被配置方式建设了3条植被过滤带,通过小区试验测定了植被过滤带对地表径流中悬浮固体的净化效果并分析了其影响因素。研究结果表明,植被过滤带能有效削减地表径流中的悬浮固体,植被条件、入流流量和入流悬浮固体浓度对净化效果影响显著,植被过滤带对悬浮固体的削减主要发生在前10m。Vegetative filter strip （VFS） is a new type of ecological engineering measures to control non-point source pollution. For this study, three VFSs of different vegetation planting modes are constructed on the bank slope of Xiaohuashan reservoir, Shaanxi Province. The measured data of plot experiments are used to determine the effect of clarification of sediments in the surface runoff by VFS and the influencing factors are analyzed. Results show that sediments in surface runoff could be reduced effectively and sediments were mainly entrapped in the first lOre of VFS. Vegetation conditions, inflow rate and inflow sediment concentration are significant factors to the clarification effect.
