摘要
该文对黄土区土壤侵蚀最为严重的切沟进行研究 .通过实地调查及建立观测设施 ,分析得出黄土区沟道的泥沙主要来自切沟 ,采用聚类分析方法对切沟进行分类 ,切沟内塌积土的数量是分类的主要依据之一 ,也是沟道治理进行造林的关键 .
This paper deals with the research on gullies in Loess Region that have been seriously eroded. The gullies were investigated on the spot and gage lashers have been constructed. The result of analysis shows that the mud and sand in channel mainly come from gullies. By means of gradual cluster analysis, the amount of the breakdown\|deposit soil in gullies is one of the main factor for the classification as well as the key point for gully erosion control and plantation.
