| 摘 要： | 分析长江上游流域5个主要控制站：金沙江屏山、岷江高场、嘉陵江北碚、长江上游干流寸滩及乌江武隆的月流量变化。结果表明,高场和北碚站的径流显著减少,寸滩站径流则稍微减少。从年内分配上看,9-11月份减少较多。寸滩站径流减少主要受岷江和嘉陵江流域降水量减少和人类活动的影响。

| Abstract: | The changes of monthly runoff at the five main control stations in the upper reaches of the Yangtze River were analyzed including Pingshan station of the Jinsha River, Gaochang station of the Minjiang River, Beibei station of the Jialing River, Cuntan station of the upper trunk river and Wulong station of the Wujiang River. It was found that the runoff at Gaochang and Beibei station decreased obviously and the runoff at Cuntan station decreased faintly. And the ratio of runoff from September to November decreased obviously as for the changes of inner distribution. Finally it was concluded that the decrease of the runoff at Cuntan station was caused by the decreases in precipitations in the Minjiang River and the Jialing River basin and the influences of human activities. |
