| 摘 要： | 应用人工模拟降雨试验,在同等试验条件下对黄土和紫色土坡面产流及产沙特征进行了对比研究.研究发现黄土坡面属于超渗产流,坡面发育较深的侵蚀沟;紫色土属于蓄满产流,坡面沟道不发育或发育微弱,且同等条件下黄土的坡面侵蚀量远大于紫色土.在制订保土措施时,应结合土壤特征选择适当的方法,以达到理想的效果.

| Abstract: | Applying the artificial precipitation experiment,the slope surface runoff and sediment yield characteristics of loess and purple soil under same experimental condition have been contrastively studied.The study results show that,loess slope belongs to excess infiltration runoff production,deeper erosion gully is developed;purple soil belongs to excess saturation runoff production,slope channel is developed weakly or undeveloped.Under same condition the slope erosion yield of loess is much greater than that o... |
