摘    要:黄河兰州以上是黄河流域主要来水区.其中基流在来水量中占有相当大的比重。近年来。由于气候变化和人类活动的影响,上游河川基流呈显著下降趋势,对黄河径流量减少产生较大影响.因此,研究黄河兰州以上基流变化对黄河水资源的影响具有重要意义。本文计算了黄河兰州以上干支流的基流量,结合地形地貌、水文地质条件,分析了黄河上游基流变化以及影响因素,阐述了基流变化对黄河水资源的影响。

关 键 词:河川基流  水资源  黄河上游  水文地质  日平均流量过程线切割法

Abstract:The region of upper Lanzhou is main runoff-producing area in Yellow river basin, and the base-flow plays an important role in the runoff. The base-flow of the upper reaches has been decreasing obviously because of change of climate and effects of human activities in the recent years, it has great influence on the decrease of the runoff of Yellow river. Therefore, it will be important to research the variations of base-flow in the region. In this paper, the base-flow of the area including main streams is calculated. Combined with the local topography and hydrogeology condition, the variations of base-flow of these rivers and influence factors are analyzed, and influence of variation of base flow on water resources of Yellow river is also analyzed.
Keywords:base-flow  daily discharge hydrograph separation method  base flow index  the upper reaches of Yellow river
