| 摘 要： | 通过对径流小区的多年观测和人工模拟降雨试验，利用自制的径流自动记录装置，研究了油松林地不同处理的产流产沙及其动态过程。研究结果表明，油松林地、林地去枯枝落叶层和采伐林地上层林木等３种处理与农地比较，分别减少径流量８８．０％、２７．０％和８７．８％，减少产沙量９９．９％、９８．０％和９９．８％。产沙量与坡度和雨强关系密切，随坡度和雨强增加而迅速增加，以雨强的效应更甚。油松林地开始产流的降雨量一般在１

| Abstract: | The flow production and sediment production and their processes were studied in the paper based on the data from observation in runoff plots for many years and from simulated rainfall experiment,using an automatic runoff recording instrument made by ourself.The results showed that,compared with farmland,the runoff in chinese pine ( Pinus tablulaeformis )stand,the stand without litter and in its cutover area with all vegetation under the stand decreased by 88 0%,27 0%,87 8% respectively,and the soil los... |
