, 2007 土质道路是当前黄土丘陵区农业生产与农村生活的主要道路,也是发生水土流失最严重的土地利用类型。若田间地块道路路面种植植物,则可以达到减少、控制道路水土流失的目的。在前人对生物道路实施的可行性、建造方法、实用性研究的基础上,在延安市燕沟小流域采用小区径流监测的方法,对12个不同处理植物路小区为期3a27场次产流降雨的产流产沙数据进行了分析。结果表明,植物道路侵蚀均发生在6—9月,其中降雨量10～25mm发生概率最高,最小产流雨为5.7mm。降雨量与降雨强度对道路侵蚀影响显著 ...

Shuitu Baochi Xuebao目的泥沙团聚体是坡面侵蚀磷流失的重要载体，其粒径分布特征是影响泥沙磷富集率的重要因素，探究不同质地土壤侵蚀产流产沙及侵蚀泥沙粒径分布与磷流失间的关系对于农业非点源污染的治理与模型研究具有重要意义。方法以丹江口库区5个质地差异的旱耕地表土为研究对象，通过模拟降雨试验，采用湿筛法分离不同粒径泥沙颗粒，探究不同质地土壤产流产沙过程中磷流失与侵蚀泥沙颗粒组成之间的关系。结果模拟降雨条件下，不同质地土壤溶解态磷流失主要集中在产流初期（0~10 min），占总溶解态磷流失的72.1%~86.5 ...
