| 摘 要： | 由于气候变化和人类活动的影响。黄土高原河川基流呈显著下降趋势。对黄河径流量减少产生一定影响。采用日流量过程线切割法计算了河龙区间黄土高原主要支流的基流量。结合地形地貌、水文地质条件，分析了不同地貌类型支流基流的特点，初步分析了影响基流变化的各种因素。认为河龙区间基流变化对黄河水资源影响较大。

| Abstract: | Base-flow of the rivers in loessial plateau of Huanghe basin has been decreasing obviously because of change of climate and effects of human activities in the recent years, which has great influence on the decrease of the runoff of Huanghe river. In this paper, the base-flow of the main rivers between Hekouzhen and Longmen of Huanghe river were calculated by using daily discharge hydrograph separation method. Combined with the local topography and hydrogeology condition, the feature of base flow in the area and the influences of climate and human activities on the variations of base-flow are analyzed. |
