摘要
泥流是重要的水土流失,在黄土塬区,由于黄土层松散深厚,温差较大,降水集中,沟道纵坡大等原因,泥流较为发育。泥流分布在切沟、冲沟中,其特征与此相一致。因之,通过3个部位的分散、拦蓄径流,使“水”、“土”分离,和对泥流的拦挡可控制泥流,减少区域土壤侵蚀。
Describes the distribution, development and control measures of mud flow in Loess Plateau gully regions. By dispersion of runoff and building of check dams, the mud flow and soil erosion can be greatly reduced.
