| 摘 要： | 通过对7块对比径流小区试验资料的分析,得出不论是林地还是荒坡地,研究区影响坡面产流的雨强因子为I_(15)(15分钟两强).由关联度分析得出对坡面产沙量影响显著的因子为径流量.试验分析表明,有林地坡面的保土效益在93.7％～99.7％,且林地的保土效益是随降雨量级的加大而增加.

| Abstract: | The research area locates in Beijing Soil and Rock Mountain. This paper analyzed the experimental data of Seven different typesof runoff plot. Through the analysis of mathematic correlative degree,it has been found that the maximum rain densith of 15 minutes (I15)is the most prominient factor inflencing overland flow,and the runoff volume is the most prominient factor influencing erosion field on hillslope. The analysis also indicates that the benefit of soil conservation for forested hillslope is 93. 7%-99. 7%,and its benefif increases as the precipitation level increases |
