Shuitu Baochi Xuebao, 2020 通过模拟室内风力、水力、冻融条件，进行单一水蚀、冻融+水蚀、冻融+风蚀+水蚀3种营力组合试验，揭示了复合侵蚀条件下的砒砂岩产流产沙变化规律。结果表明：（1）相同降雨条件下，冻融+水蚀、冻融+风蚀+水蚀试验的径流量均为水蚀试验的1.2倍，产沙量分别为水蚀试验的2.4，2.8倍。冻融能够增大砒砂岩产流产沙量，风蚀对增加侵蚀产沙量的作用较小。（2）砒砂岩产流产沙过程的峰值及变幅随营力种类的增多而增大，单一水蚀的产流产沙过程相较于复合营力作用下的水沙过程具有显著的坦化特征。（3）复合侵蚀作用使初始入渗率增加 ...

Shuitu Baochi Xuebao, 2022 侵蚀性降雨是引起喀斯特黄壤坡面水土流失的主要动力因子。采用贵州省遵义市浒洋水流域2018—2020年4个径流小区92次侵蚀性降雨产流产沙实测数据,研究次降雨条件下,裸露坡面和块石出露小区对产流产沙的影响。结果表明:(1)侵蚀性降雨可以分为A、B、C 3类,A类降雨是造成喀斯特黄壤坡面土壤侵蚀的主要雨型。侵蚀性降雨的标准为次降雨量＞6.6 mm或I30＞3.6 mm/h。(2)裸露坡面63.27%的侵蚀性降雨径流深＜0.4 mm,66.30%的侵蚀性降雨土壤流失量＜1 g/m2 ...

Shuitu Baochi Xuebao, 2008 利用自行设计的双土槽径流小区系统和人工模拟降雨试验研究方法,研究了坡面侵蚀方式演变对坡面侵蚀产沙量的影响,分析了沟蚀发育不同阶段对坡面侵蚀产沙的贡献。结果表明,坡面侵蚀发育初期,沟头溯源侵蚀占主导地位,侵蚀产沙量呈增加趋势;坡面侵蚀发育中期,沟蚀的宽度和深度变化已属于切沟形态发育的范围,导致了侵蚀产沙量的急剧增加;坡面侵蚀发育后期,沟蚀发育过程处于后期稳定阶段,侵蚀产沙量变化伏动较小。在坡面侵蚀发育初期、中期和后期,沟蚀分别占坡面总侵蚀产沙量的28.7%,70.4%和37.1%。
