中文摘要	采用统计分析、相关性分析、滑动平均法和Mann-Kendall趋势检验等方法,对黄河上游沙漠宽谷河段主要控制站下河沿、石嘴山及头道拐近期水沙变化特点和变化趋势进行了分析。研究认为:1990年以来河段水沙异源的特点更加显著;2000年以来各站径流量和输沙量减少明显,与1990年以前相比分别减少24.8%~39.8%和36.6%~73.6%;径流量和输沙量在汛期的集中程度降低;水文站水沙关系变化不大;趋势分析表明各站水沙均呈显著减少趋势,且输沙量的减少比径流量更明显,其中头道拐站减少幅度最大。同时对影响沙漠宽谷河段水沙条件变化的降水量、引水引沙、支流来水来沙、水库运用、河道冲淤调整等因素进行了初步分析。
英文摘要	This paper is intended to reveal important characteristics and varying tendency of the runoff and sediment load measured at the major hydrometric stations on the Upper Yellow River by using statistical analysis, correlation analysis,moving average and the Mann-Kendall trend test. The research results show,among others,that the feature of runoff and sediment load from different source areas has become more apparent since 1990 compared with those before 1990. The average annual runoff and sediment load measured at Xiaheyan, Shizuishan and Toudaoguai hydrometric stations in 2000 - 2009 decreased by 24. 8% ~ 39. 8% and 36. 6% ~ 73. 6%, respectively,with less contributed in the flood seasons. Meantime,the relation of water flow and sediment load changed insignificantly. Besides,the trend analysis shows significant decrease in both runoff and sediment load,with more significant decrease in sediment load,especially at Toudaoguai hydrometric station. Meanwhile,a preliminary analysis of factors affecting the runoff and sediment variation,such as precipitation, water and sediment diversion,incoming water and sediment load from tributaries,reservoir operation and river channel adjustment is made.
