摘 要:
道路引起的径流汇集及道路侵蚀的不断演化常常是沟蚀加剧的诱因，未铺装路面上形成的侵蚀沟及坡面侵蚀来沙在路面上的堆积，也会严重影响正常交通运输。国内外许多学者已从不同角度关注道路侵蚀。文章回顾近20年来国内外有关道路侵蚀的研究工作及所取得的成果，分析目前研究存在的主要问题。针对中国侵蚀环境特征及侵蚀产沙特点，对未来道路侵蚀研究工作开展进行展望。[著者文摘]

Abstract:
Road network plays an important role in initiating hydrological change and contributing to erosion process in a watershed because of the cutting of overland flow pathways and sediment transportation. Roads in a watershed can generate the flow collection along slopes and road-related erosion can also enhance gully erosion. Gully erosion occurring on the roads as well as corresponding sediment deposition may hinder traffic： In order to determine the contribution of road networks to soil loss, most attention has been given to road erosion and its impacts on hydrological and sediment transport process in a watershed in many countries over the world on the base of the data from field investigation and experiments. A lot of results dealing with road erosion process and sediment storage have been obtained. In this paper, we reviewed and discussed the researches on road erosion conducted in recent 20 years, and summed the results obtained by representative researchers in different parts of the world. At last, according to geographic features and soil loss, some suggestions and prospects on studies about road erosion in China have been given.[著者文摘]
