Shuitu Baochi Xuebao, 2022 以滇东海峰岩溶盆地土壤复合侵蚀过程为研究对象,分析综合土壤可蚀性指数(CSEI)的分布特征,探讨地表、地下土壤可蚀性的关联性、变化趋势及其影响因素,以期深入认识岩溶地区土壤侵蚀机理,治理石漠化现象。通过野外调查取样结合土壤比重计法、团聚体湿筛等方法,分析了滇东岩溶断陷盆地地表、地下不同侵蚀场土壤的理化性质及可蚀性变化特征。结果表明:(1)土壤理化性质随侵蚀过程发生变化。土壤中黏粒、SOC、大团聚体(>0.25 mm)呈递减趋势,粉砂、小团聚体(地下漏失过程(15.30%~30.86%,43.63%~64.

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 ...

Extent of Cropland and Related Soil Erosion Risk in Rwanda (卢旺达农田面积扩张带来的土壤侵蚀风险研究)
, 2016 在非洲，农田开垦是造成土壤侵蚀的主要原因。本研究以卢旺达为例，评估了该国当前的农田面积和土壤侵蚀情况。卢旺达是非洲最近十年人口增加和农田扩张最快的国家。我们利用 Landsat-8 影像，得到了卢旺达 2015 年的土地利用和覆被数据。基于降水、土壤性质、数字高程模型（DEM）、归一化植被指数（NDVI）和土壤保护因子数据，驱动 RUSLE（Revised Universal Soil Loss Equation）模型，评估了卢旺达的土壤侵蚀速率，空间分辨率是 30 米。模型结果显示 ...

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 ...
