Coupling Relationship Between Detachment Rate with Sediment Load and Rill Length
, 2001 土壤剥蚀是指由侵蚀动力引起的土壤颗粒从土壤母质移动的过程。细沟剥蚀土粒随着细沟股流中含沙量的增加而减少 ,已有的一些侵蚀模型 (如 WEPP)均提到了这一点。用黄土高原一种典型的粉壤土 ,在 5种坡度、3种流量下进行了细沟侵蚀模拟试验。对试验结果进行了回归 ,分析了黄土高原斜坡及陡坡地、细沟股流剥蚀率随含沙量以及沟长变化的函数关系。这对细沟侵蚀动力过程的研究深入 ...

, 2017 细沟侵蚀规律的解译对于坡面治理具有重要的理论与实践意义． 通过 10m 坡长条件下 10°和 25°坡面人工模拟降雨试验与高清摄像技术，研究了细沟侵蚀 的时空动态变化特征． 结果表明 10°坡面单位坡长总侵蚀量和细沟侵蚀量均随 距坡顶距离的增加先增大后减小，而 25°坡面却呈现不断增加的趋势，但其增加 速率逐渐减小． 10°坡面平均含沙量随降雨历时先减少后增加，而 25°坡面却先 增加后减少． 高清摄像技术可表征降雨过程中细沟平面形态变化，25° ...

Shuitu Baochi Xuebao目的研究不同秸秆还田年限对细沟侵蚀阻力的影响，可为秸秆还田坡地细沟侵蚀过程模拟与防治提供科学依据。方法以秸秆还田0 a（CK）、3～4 a（R1）、5～6 a（R2）、7～8 a（R3）、9～10 a（R4）、15 a（R5）和20 a（R6）为研究对象，通过土样采集与分析，利用偏最小二乘回归分析，明确秸秆还田条件下土壤侵蚀阻力的主控因子。结果1）随秸秆还田年限的增加，细沟可蚀性（Kd）呈先降低后增加再降低趋势，R2、R3、R5和R6处理Kd均显著低于CK处理［170.38 cm3/（N·s ...
