摘要
通过研究地表径流对地形地貌的改造侵蚀过程及产生的水土流失问题,以及对相关学者研究成果进行总结,结果表明,地形地貌特征与水土流失均与地表径流存在直接相关联的关系,大趋势上地形地貌的改变是地质侵蚀时期发生的各种构造运动作用的结果,而局部产生的地形地貌是地表径流作用产生的,造成水土流失的主要侵蚀营力是地表径流作用的结果,地表径流与冻融侵蚀、土壤侵蚀相互作用加剧了水土流失。
By studying the erosion process of surface runoff on topography and landforms and the resulting water and soil loss,as well as summarizing the research results of related scholars,the results showed that the landform characteristics and soil erosion were directly associated with surface runoff,the relationship between changes in trend on topography of geological erosion period was the results of various tectonic movement effect,and the topography was generated by the local function produced by the surface runoff,soil erosion in the main force was the result of the role of surface runoff,erosion camp surface runoff,soil erosion and freeze-thaw erosion exacerbated the interaction between soil and water loss.
