| 摘 要： | 采用流域平行对比和自身对比两种方法，利用实测水文资料，从理论上分析了森林植被变化对小流域暴雨径流及洪水流量过程的影响。结果表明：森林覆盖率高的流域拦水能力较高，能显著地削减洪峰、延缓洪水过程，降低径流系数，使次暴雨径流量的变差系数c，增大。

| Abstract: | Based on the measured data,the impacts of forest vegetation change in small watershed on storm runoff and flood process have been analyzed theorectically by two methods of parallel observation in the comparable watersheds and contrast by itself.The results are as follows: the watershed with high vegetation coverage can largely intercept water, decrease flood peak,lengthen flood process and intensify variation coefficient in storm runoff. |
