| 摘 要： | 基于有关水文、气象台站的降水、气温和径流观测资料,对天山南、北坡的代表性河流——开都河与乌鲁木齐河上游山区径流变化及其对气候变化的响应进行了分析。在此基础上建立山区径流对气候变化的响应模型,假定不同的气候情景组合,就两条河流出山径流对气候变化的敏感性进行分析对比。结果表明,近40余年,两条河流山区年降水量、平均气温及径流总体上均呈波动状上升态势。一方面径流与降水、气温的变化呈明显的正相关关系;另一方面山区径流对降水、气温变化的响应的程度存在着明显的区域性差异,即乌鲁木齐河出山径流对降水变化的响应程度明显强于开都河,而开都河出山径流对气温变化的敏感性要高于乌鲁木齐河。 |
| 关 键 词： | 径流 气候变化 敏感性 乌鲁木齐河 开都河 天山 |

| Abstract: | Change of runoff and climate in mountain watersheds of Kaidu river and Urumqi River originated respectively from the south slope and the north slope of the Tianshan Mountains was analyzed based on the past 50a observational data at relevant hydrological and weather stations,and the various climate scenes were assumed and the response models of mountain runoff to climate change were established to analyze sensitivity of runoff to climate change.The results are as follows.Variations of temperature,precipitati... |
| Keywords: | runoff climate change sensitivity Urumqi River Kaidu River Tianshan Mountains |
