| 摘 要： | 采用模拟降雨的方法对鲁中山区坡面土壤降雨条件下产流、产沙和侵蚀方式的演变过程进行了研究,结果表明:产流量都是随时间递增最终达到稳定产流,但是各次降雨达到稳定产流的时间均随降雨强度和坡度的增大而递减。相同坡度条件下120mmh-1雨强产流较60mmh-1雨强先到稳态,而相同雨强条件下10°坡面则较5°坡面先达到稳态。产沙量呈递增趋势且逐渐达到稳定产沙,达到稳定产沙的时间随雨强和坡度的增大而递减。相同坡度条件下120mmh-1雨强处理较60mmh-1雨强处理先达到稳态,相同雨强条件下10°坡面比5°坡面产沙过程先达到稳定产沙状态;在降雨过程中坡面首先产生面蚀,后出现细沟侵蚀;面蚀率随降雨历时延长有减小趋势,但变幅较小,细沟侵蚀率随降雨时间先急剧增加后保持稳定。

| Abstract: | In this experiment,the runoff yield,sediment production and soil erosion type variation during the single simulated rainfall term were determined.The results showed that the runoff yield of different treatments divided two terms that were adding quickly and adding slowly during the simulated rainfall process.When the slope degree was same,the 120 mm rainfall intensity treatment got the stable state earlier than the 60 mm rainfall intensity treatments.And,when the rainfall intensity was same,the 10 degree ra... |
