| 摘 要： | 以长江上游流域6个主要控制测站实测数据为研究基础,利用Kendall秩次相关法对长江上游流域径流变化趋势进行分析.结果表明:除金沙江屏山站全年和乌江武隆站汛期径流略有增加外,其它测站控制流域内径流均有不同程度减少,其中嘉陵江北碚站、岷江高场站和沱江富顺站径流均显著减少,长江上游干流控制站寸滩站径流则微弱减少.结合CIS...

| Abstract: | Kendall correlated method was employed to analyze the variations of runoff of the upper Yangtze River based on the data collected by six major stations along the main stream.The results indicated runoff of some stations decreased differently while the Jinsha River and Wujiang River were exceptional;runoff of Jialing River,Minjiang River and Tuojiang River decreased greatly and that of Cuntan Station decreased a little.Distributed hourly water balance model was established based on GIS and DEM and its applic... |
