中文摘要	石羊河流域的年平均气温（最高、最低气温）自1951年以来总体呈上升趋势，增温速率为0．22℃／10a，增幅达1．2℃。1992年是年平均气温显著变暖的年份，与显著变暖前相比，年平均气温上升了0．85℃，低于近51年1．1℃的增幅水平。在近55年中，石羊河流域的年降水总体上在增加，出山口径流量在减少，流域尾闾民勤绿洲的地下水位在快速下降。气温显著变暖后，年降水量增加了约18．2mm，增幅达5．8％，出山口径流量减少了4．1*10~8m~3，民勤绿洲的地下水位下降了1倍～2倍。水资源变化的成因分析表明，出山口径流量的减少源自径流补充之一的上游山区降水的减少，而红崖山水库入库径流量的持续快速减少则是民勤地下水位快速下降的主要原因之一。受气候变化的影响，石羊河流域出山口径流量峰期有所提前，而人类活动严重地影响了石羊河流域中游地表径流利用量和下游可利用量分配比例。
英文摘要	In Shiyang River basin, the annual average temperature （maximum and minimum temperatures） is sustaining upward trend since 1951, warming rate is of 0.22℃/10a, an increase is of 1.2℃. The average temperature is significant warming in 1992. Comparing with the significant warming ago, the an- nual average temperature rose by 0.85℃, lower than the 1. 1℃ increase in recent 51years. The annual precipitation is increasing trend, runoff pass going out of Qilian mountain is decreasing trend, the ground water level of Minqin oasis is downward trend in recent 20 years. After temperature warming, the annual rainfall increased by 18.2 mm, an increase of 5.8%, the runoff pass going out of Qilian mountain to reduce the 4.1* 10~8m~3 , the depth of the ground water level has dropped about 1-2 times in Minqin oasis. The causes of water resources change show that the reduction mountain precipitation in the upper reach of shiyang River basin is one of the reasons for the reduction of runoff pass going out of Qilian mountain, Hongyashan reservoir inflow to the sustained and rapid reduction eventually led to the rapid decline in the groundwater level. Subject to the impact of climate change, the peak of runoff pass going out of Qilian mountain of shiyang River basin ahead of time, human activities is the main reasons for the change of run- off consumption in midstream and utilization of available volume in downstream.
