摘要
天山北坡四棵树河是乌苏市工农业生产和经济发展的主要水源地,同时也是乌苏市洪水灾害出现比较频繁的河流.应用1954-2006年乌苏市气象站年气温、降水量与吉勒德水文站资料,分析了四棵树河流域径流的年内、年际变化特征,估算出冰川径流量.结果表明:水资源对气候变化十分敏感,以河流冰川径流变化对气温、降水等气候因子变化的响应,揭示出冰川径流的变化特征及其对河川径流的可能影响.近几十年来,由于气候变暖,加上人类活动影响,导致水循环加剧,给生态环境、人类生活和社会经济发展带来重大变化.对于干旱区域独具特色的水文和水资源系统,应正视社会经济发展与生态环境保护问题,采取多种措施,减缓气候变化,遏制区域环境的恶化趋势,保护好干旱地区的生命线—高山冰川,维系干旱区十分脆弱的生态环境.
The Sikeshu River is the main water resources for the industry and agriculture production and the economy development of Wusu Municipality,and is also a river with frequent flood disaster.In the Sikeshu River basin,owing to short of water resources and the increasing contradictory between water supply and demand,the local economy development is seriously restricted.In this article,taking the Sikeshu River runoff as the main object of study,the change characteristics of monthly runoff and annual runoff are analyzed,and based on the studies of the predecessors,the meltater runoff is estimated.The water resources are very sensitive to the climate change.Analyzing the responses of meltwater runoff to the climatic factors,such as air temperature and precipitation,the changing characteristics of the meltwater runoff in the Sikeshu River and their potential influence to the river runoff are revealed.In the past some years,water cycle has intensified,resulting from of the climate warming and the human activities,that brings about a tremendous change in ecological environment,the human life and the socio-economic development.Hydrology and water resources system in the arid regions should face up to the socio-economic development and the ecological environmental protection and must take many measures to slow down the effect of climate change,to keep within limits the regional environment worsening,to protect the mountain glaciers,the lifeline in arid regions,and to hold together the very vulnerable ecological environment.
