黄土丘陵区不同盖度生物结皮对坡面产流及SCS-CN模型CN值的影响
Shuitu Baochi Xuebao, 2021 以黄土丘陵区典型退耕地不同盖度的生物结皮坡面为研究对象，通过野外人工模拟降雨试验，研究不同盖度生物结皮对坡面产流的影响，解析了生物结皮盖度与SCS-CN径流模型参数CN值的关系。结果表明：（1）在90 mm/h雨强条件下，初始产流时间随生物结皮盖度增加而降低，低盖度（0~20%）生物结皮坡面初始产流时间分别为中盖度（40%~60%）和高盖度（80%~100%）的1.64，2.46倍；（2）降雨前15 min，高盖度生物结皮较中、低盖度生物结皮促进产流，15 min后，高盖度生物结皮较中 ...
