摘要
利用1960-2003年密云水库流域降水及径流资料，分析年径流量的变化，建立流域降雨径流关系，讨论降雨径流关系的影响因素．分析表明，流域降水和土地利用类型的改变不是径流量减少的决定因素，而是土壤植被，上游截流和人口经济发展的综合结果．
According to the data of rainfall and runoff from 1960 to 2003 around the watershed of Miyun Reservoir, the relationship between rainfall and runoff variation of the watershed was obtained. And then, the influencing factors of relationship between rainfall and runoff were generalized. Through correlation analyzed, the change of annual rainfal! and land use are not major motivating factors of the runoff decreasing. The inflow of Miyun reservoir responds directly to soil and vegetation changes, upriver extension interception, human activities and economic development.
