Shuitu Baochi Xuebao, 2021 为了研究植被对坡面细沟侵蚀调控机制，采用模拟降雨试验，结合激光扫描方法，分析了不同草带分布沟坡面细沟侵蚀发生、发展过程。结果表明：草带位于梁峁坡下部60%，植被调控侵蚀效果最优，相比裸坡减少径流量7.4%，减少产沙量62.9%，相比蓄水减沙功效而言更具直接拦沙的功能。植被通过调控细沟侵蚀的发生、发展、发育过程实现了对土壤侵蚀的调控作用，尤其是对沟坡侵蚀产沙的调控作用；而且这种对侵蚀的调控作用不仅改变了细沟侵蚀发生的位置，而且改变了径流和侵蚀过程以及侵蚀方式；细沟侵蚀已经向面蚀（片蚀）转化 ...

10Be和26Ai揭示的合黎山西南部侵蚀速率初步研究 [PDF]
, 2018 地表侵蚀速率是衡量地貌演化的一个重要因子。本研究利用原地宇宙成因核素 10Be 和 26Al 对合黎山西南部地表岩石侵蚀速率进行了首次测定。结果显示：约 30 ka 以来，合黎山西南部的地表岩石侵速率约为 24 mm∙ka-1。这一结果与已见报道的其他基岩侵蚀速率值一致。这一结果与 Small et al 获得的非干旱地区的基岩侵蚀速率也基本一致，但是显著高于干旱的南极地区和半干旱的澳大利亚。10Be 和26Al 获得的侵蚀速率的良好一致性表明本研究中所用侵蚀模式的有效性。所得的侵蚀速率小于 ...
