降雨、汇流和坡度对黑土浅沟坡面侵蚀影响的试验研究

Shuitu Baochi Xuebao
[目的] 为研究降雨、汇流和坡度对浅沟侵蚀的影响,实施精确的水土保持措施。[方法] 通过室内模拟降雨和汇流试验,设计2个降雨强度(50,100 mm/h)和2个坡度(3°,7°),并在4种降雨强度和坡度组合下设置5个依次增加的汇流强度(15,30,45,60,75 L/min),分析降雨、汇流和坡度及其交互作用对浅沟坡面侵蚀的影响,明确浅沟侵蚀对坡面侵蚀的贡献。[结果] (1)坡度和汇流强度对浅沟坡面侵蚀的影响均大于降雨强度。当降雨强度由50 mm/h增加到100 mm/h时,3°和7 ...

大巴山泥石流侵蚀作用及防治对策研究

Shuitu Baochi Xuebao, 1993
通过对大巴山泥石流形成和发育过程的研究，从侵蚀机制的角度，将其分为坡面侵蚀，沟谷侵蚀，复合侵蚀三种基本的侵蚀类型，并进一步分析了不同影响因素在各类泥石流发育中所起的作用，认为：坡面侵蚀型泥石流的发育与植被关系最密切；沟谷侵蚀型泥石流的发育对暴雨的依赖性最大；复合侵蚀型泥石流的发育与沟岸的不稳定有很大关系。最后，针对性地提出了大巴山区各类泥石流的防治重点。
