摘要
黄土高原土壤侵蚀异常强烈,并且大部分地区以水蚀为主。在水蚀区,土壤侵蚀主要由少数几次暴雨所引起。黄土高原的土壤侵蚀情况比较复杂,以各种类型的沟蚀为主,并具有垂直分带性。坡耕地的土壤侵蚀,占总侵蚀量的比重很大。同时,根据在子午岭地区的土壤侵蚀调查,讨论了植被对土壤侵蚀的影响。
Soil erosion on the loess plateau is very serious with water erosion in the main in most parts of the region. In water erosion area, soil erosion is caused by the several few heavy rainfalls. Soil erosion on the loess plateau is very complicated with various types of gully erosion in the main characterized with vertical belt erosion. Soil erosion on the slope land consists of the major part of totaI erosion in the Ziwuling Mountain area. This paper also discusses the effects of vegetation cover upon soil erosion.
