半干旱丘陵地区乡村道路侵蚀研究——以内蒙古四子王旗南部为例

Research on the Road Erosion of the Rural Area in the Semi-arid Hill Region——Taking the Southern Region of Siziwang County as An Example

以内蒙古阴山北麓的四子王旗南部为研究对象,通过实地考察,研究道路侵蚀的分布特点、侵蚀特点、形成原因以及道路侵蚀的发育方式等.结果表明,四子王旗的道路侵蚀分为3个阶段,其中处于侵蚀初期的道路主要位于集水区,3个阶段都有发育的主要位于汇水坡面上.

Taking the southern region of Siziwang County that lies on the northern of Yinshan Mountain in Inner Mongolia as a research object and with the method of field survey, the distributing characteristics of the road erosion, the erosion characteristics,the form reason and the development mode of road erosion,etc, are studied. The results show that the road erosion of Siziwang County can be divided into three phases. The initial stage of road erosion lies mainly on the catchment areas, and the road erosion including all development phases lies mainly on catchment slopes.
