降雨侵蚀力研究进展

Shuitu Baochi Xuebao, 2002
降雨是导致土壤流失的动力因素,降雨侵蚀力反映由降雨引起土壤侵蚀的潜在能力,准确评估计算降雨侵蚀力是定量预报土壤流失的重要环节.本文回顾总结了国内外降雨侵蚀力的研究进展,在此基础上提出了我国今后降雨侵蚀力研究的发展方向.

北京市近40年来降雨侵蚀力时空变异特征

Shuitu Baochi Xuebao
[目的] 降雨侵蚀力可以反映降雨对土壤侵蚀的潜在作用,是评价区域土壤侵蚀风险的重要指标。分析北京市1981—2020年降雨侵蚀力时空变异特征,对科学评估和防治区域水土流失风险具有重要意义。[方法] 基于1981—2020年北京市及周边地区119个雨量站点逐日降水数据,采用Kriging插值、Mann-Kendall非参数检验、小波分析等方法对北京市年降雨侵蚀力和中雨(10~25 mm)、大雨(25~50 mm)、暴雨(≥50 mm)降雨侵蚀力的空间分布、趋势变化以及周期变化特征进行分析。[结果 ...

模拟降雨条件下坡度和降雨强度对桂南崩积体侵蚀产沙的影响

Shuitu Baochi Xuebao
[目的] 探究坡度和降雨强度对崩岗崩积体坡面侵蚀产沙特征的影响,为桂南地区崩积体水土流失预测及其防治提供科学依据。[方法] 采用室内模拟降雨试验,研究不同坡度(15°,20°,25°)和降雨强度(60,90,120 mm/h)条件下崩积体坡面侵蚀产沙过程。[结果] 各坡度条件下,60 mm/h降雨强度时,崩积体坡面侵蚀速率变化过程较为稳定,且侵蚀速率多低于5.0 g/(m2·s),并呈现出一定的下降趋势;90~120 mm/h降雨强度下,侵蚀速率呈先波动增大后波动减小的变化趋势 ...
