Factors Analysis of Slope Runoff and Sediment Based on
, 2012 基于坡面不同植被措施下多场室外人工模拟降雨试验,采用通径分析和灰色关联理论研究了植被、降雨及下垫面等因素对坡面次降雨径流总量和泥沙总量的不同影响作用。结果表明:1)通径分析与灰色关联分析结果基本一致;2)降雨强度、植被覆盖度和土壤前期含水量是影响坡面次降雨径流总量的3个最重要因子,其次分别为植被类型、降雨历时、植被生长阶段和坡度;3)植被覆盖度和降雨强度是影响次降雨泥沙总量最重要的两个因子,降雨历时对泥沙总量的影响作用最小 ...

Experimental Study on Erosion Pattern Evolvement and Sediment Process on Loessal Hillslopes
, 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%
