植被过滤带（VFS）在控制来自坡地土壤侵蚀地表径流的输沙量有效性方面，很少有人进行研究和评价。本文以7％和12％坡度小区研究为基础，研究VFS对来自18.3m连续休闲地带泥沙浓度、径流量和土壤流失的影响。同时设计了一个径流收集分流箱设备，来收集VFS不同地段的径流样品。在VFS地段安置一套6个相间的分流箱，在观测期内，共收集13次降雨产流样品。在3．0mVFS处能截留70％的径流泥沙，同时，在9．1mVFS处截留了85％的泥沙。随着VFS宽度的增加，径流中泥沙浓度的变化很小。在所有VFS中，12％坡度与7％坡度小区相比，有较大的径流和土壤流失。VFS能促进径流中水分的入渗，减少径流量和径流中泥沙的含量。
Vegetation filter belt (VFS) Few studies and evaluations have been conducted to control the effectiveness of sediment transport from surface runoff from slope soil erosion. Based on the study of 7% and 12% sloping plots, this paper studied the effect of VFS on sediment concentration, runoff and soil loss from a continuous leisure area of 18.3 m. At the same time, a run-off collection shunt box was designed to collect runoff samples from different sections of the VFS. In the VFS site, a set of six phase splitter boxes were installed. During the observation period, a total of 13 rainfall runoff samples were collected. At 3.0mVFS, 70% of the runoff sediment can be retained, while 85% of the sediment is trapped at 9.1mVFS. As the VFS width increases, the sediment concentration in the runoff changes little. In all VFSs, 12% slope has greater runoff and soil loss compared to 7% slope cells. VFS can promote runoff water infiltration, reduce runoff and runoff sediment content.
