本文从泥河沟流域的土壤侵蚀现状入手,分析了该流域的土壤侵蚀方式及分布规律,以及流域的主要产沙部位和土壤侵蚀的成因。认为,该流域的土壤侵蚀方式具有明显的垂直分布规律,人类活动可以改变土壤侵蚀方式的分布;原面的中上部和沟谷中上游黄土裸露陡坡是该流域的主要产沙区;其土壤侵蚀主要是降雨因素,地形因素,土地利用因素和人类活动造成的。并提高相应的治理建议。
This article starts from the current situation of soil erosion in Nihegou watershed, analyzes the pattern of soil erosion and its distribution, as well as the main sand production sites and the causes of soil erosion in this basin. It is considered that the pattern of soil erosion has obvious vertical distribution and the human activities can change the distribution of soil erosion patterns. The middle and upper part of the upper surface and the bare steep slope of loess in the middle and upper reaches of the valley are the main sand-producing areas in this basin. It is caused by rainfall, topography, land use and human activities. And improve the corresponding governance advice.
