| 摘 要： | 应用黄河上游重要水源补给区玛曲县气温、降水资料分析得出:气温年际变化呈上升趋势,降水量年际变化呈下降趋势。气候变化导致可能蒸发量增加,可利用水资源量减少。水资源量多项式拟合变化趋势呈2谷1峰波动型,枯水期年际变化的时间尺度成倍延长。

| Abstract: | By using the data of temperature,rainfall during 19672005 and soil water content during 1996-2005 from Maqu County,which is located in the upper stream of the Yellow River and is an important water replenishment region for the Yellow River,the climate change and its impact on water resource there are analyzed.Results show that the annual trend of temperature is rising but rainfall is declining,and climate change results in the potential evaporation increase and the available water resources decrease.The polynomial fitting curve of water resource presented fluctuation with a two-vale and one-peak,and the time scale of annual change in low water period prolonged doubled. |

| Keywords: | Maqu climate change available water resource water replenishment region |
