摘　　要：土质道路是当前黄土丘陵区农业生产与农村生活的主要道路,也是发生水土流失最严重的土地利用类型。在野外调查研究定位监测的基础上,采用室内人工降雨与人工放水冲刷组合模拟试验的方法进行实验模拟,对该地区土质道路硬地面次降雨侵蚀产流、产沙、侵蚀过程及机理进行了初步研究,为该地区土质道路侵蚀与防治提供了科学依据。The earth road is the mostly road which bears the agro-productive activity and villagers~ daily life in the loess hilly region. Based on field investigation, locative observation data, experimental methods of simulated rainfall and simulated pouring, the preliminary results about the runoff, roads erosive process, anticorrosion mechanism and impact factors during rainfall event on the hard surface roads in this region were reported, which offered scientific evidence for controlling road erosion in this region.
