选择银武高速公路同心至固原段为研究区，设计4种不同的植被配置模式，同时设立对照，采用插签法观测面蚀，分析不同植被配置对公路面蚀量的影响。试验结果表明：植被可有效的保护高速公路边坡，明显减弱面蚀；面蚀量与降雨量之间存在对数函数关系，面蚀量随降雨量的增加而增大，但是有植被的地方增加速率明显低于无植被区的；沙冬青＋冰草（移植）＋苜蓿配置模式防护效果最好，效益最佳。

Chose the section of guyuan to tongxin of yinwu high way for the study area, designed four different vegetation pat- terns, set up comparison, surface erosion was measured by poker bar method, analyzed the affection of surface erosion for the different vegetation patterns. The result showed that vegetation can effectively protect the highway slope, significantly re- duced the surface erosion; the relationship of the the amount of surface erosion and rainfall is logarithmic function, the the a- mount of surface erosion increase with the increase of rainfall, but the rate of vegetated areas is lower than vegetated - free ar- eas obvious. The protective effect of Ammopiptanthus + Agropyron + Alfalfa is best, the benefit is best also.
