| 摘 要： | 采用小流域平行对比法,分析研究小流域的次降雨洪水过程,研究水土保持综合治理对小流域洪水的作用过程,通过双环入渗法测定流域土壤入渗速率,分析不同土地利用类型对土壤入渗速率的影响,结果表明,水土保持林草措施通过改变流域下垫面条件,改善土壤的入渗性能并对洪水过程产生影响。

| Abstract: | In this paper,the effects of the soil and water conservation measures on surface runoff process in small watersheds were analyzed by the parallel observation in two comparable watersheds of Qinba mountanious region.The land cover is changed by the soil and water conservation and so the characteristics of infiltration detected by dual rings method is various in different land uses.All of these make the runoff process of the small watersheds changed. |

| Keywords: | soil and water conservation small watershed runoff process infiltration |
