摘要
黄土高原沟壑区沟坡开发的关键是加强农业基础设施建设，其中最重要的是改善交通条件。本文通过调查，定位监测和野外人工径流冲刷试验，结合土壤容重试验资料，在对沟坡道路侵蚀进行分类研究基础上，对不同沟坡道路侵蚀的影响因素进行综合分析，首次系统地总结出道路防蚀措施的技术体系；提出道路规划设计的技术指标，施工定线的作业方法，并对修筑沟坡防蚀道路效益进行了评估。
The key measure of gully-slope land developing is to strengthen basic agricultural condition constructing in gully region of Loess Plateau,and the most important thing is to improve transportation conditions.By means of locative observation,field investigation and artificial runoff scouring,combining with soil density data,the classification of gully-slope road erosion and its effective factors are analysed.Road erosion controlling system is summed at first time and technical index of road design and operation method are put up forward.At last the benefit is evaluated.
