| 英文摘要 | The sedi ment load and river sedimentation of the upper reaches of Yangtze River has been undergoing constant changes as co mplex landfor m, large mountain area and plentiful precipitation make the drainage area of Yangtze River very vulnerable to water erosion and gravity erosion . Through analyzing the hydrological and sedi ment load statistics recorded by major hydrological stations along Yangtze River since 1950s, and editing the accumulation graph of annual runoff volume and annual sedi ment load, we find out that the suspended- sediment of Yangtze river has been decreasing year by year in Wulong Hydrological Station on Wujiang River, Beibei Hydrological Station on Jialingjiang River, Lijia wan Hydrological Station on Tuojiang River and GaochangHydrologicalStation onM injiang River, YichangHydrologicalStation, Cuntan Hydrological Station along Yangtze River mainstream share the sa me experience too . But the statistics obtained at Pingshan Hydrological Station on Jinshajiang River shows the sedi ment load there has increased . Taking ecological construction, hydraulic engineering construction and precipitation changes into consideration, the thesis analyses the causes for the sedi ment load decrease of Jialingjiang River, Tuojiang R iver, M injiang River and Wujiang River and provides us both scientific foundation for further study of river sediment changes of the upper reaches of Yangtze River, and measures to control river sedimentation. |
