不同近地表水文条件下矿山弃土对土壤细沟可蚀性的影响—以攀枝花盐边县龙蟒矿山为例
Shuitu Baochi Xuebao, 2016 以攀枝花盐边县红格龙蟒矿山李家河排土场、未被开采过的矿区灌草地和耕地3种土壤为研究对象，基于土壤水蚀预报模型(WEPP)中细沟侵蚀模型，采用100，200，300，400，500，600 ml/min的流量对灌草地、耕地和矿山排土场土壤分别进行排水、饱和以及渗流状态下的冲刷试验，查明其可蚀性(Kr)的变化。结果表明：（1）径流剪切力与土壤剥蚀率之间存在较显著的指数关系（P＜0.01）；（2）流量与土壤剥蚀率之间存在较为显著的指数关系（P＜0.01），土壤剥蚀率随流量的增加呈指数形式增加;（3）在排水 ...
