摘　　要：从2007年起至2012年止,三峡水库的正常蓄水位将逐步从156.0 m抬升至175.0 m,水库正常蓄水位以下防洪库容较初期规模增加110.7亿m3,较2007年汛期增加153.3亿m3,可以发挥正常运行期的防洪效益;兴利库容较初期规模可增加年电量147亿kW.h,较目前的运行水位情况可增加年发电量70.8亿kW.h;改善航道里程将增加约90 km,位于库区的万州、涪陵等港口将成为深水港,水域条件大为改善,综合利用效益增加显著;枯水调节流量可从目前的约4 400 m3/s提高到最终规模的5 860 m3/s。From 2007 to 2012,the normal water level of Three Gorges Reservoir will be gradually raised from 156.0 m to 175.0 m.The flood storage capacity will increase 11.07 billion m3 to the initial operation,and 15.33 billion m3 to 2007 flood season.The power generation will increase 14.7 TWh to the initial operation,and 7.08 TWh to the current operation.About 90 km navigating channel in upper reach will be improved,and the Wanzhou,Fuling and other ports will be a deep-water port.The flow in dry season will increase from about 4 400 m3/s to 5 860 m3/s.The comprehensive utilization benefits of Reservoir will increase significantly.
