摘　　要：与初步设计相比,三峡枢纽自2003年蓄水运用以来,运行环境发生了较大变化,如长江上游建成一批大中型水库、水文气象预报技术提高、防洪、发电、航运、供水、生态对水库调度需求增加等。为适应新的运行环境,2009-2012年,三峡水库采取了提前蓄水、中小洪水调度、汛限水位浮动等优化调度措施,以提升三峡工程的防洪、发电、航运、供水等综合效益。同时,开展了有利于四大家鱼繁殖的生态调度试验,试图拓展三峡工程的生态效益;实施了消落期库尾减淤和汛期沙峰调度试验,通过减少库尾及库区泥沙淤积来持续保证三峡水库的有效库容。此外,通过在三峡船闸上下游增设靠泊设施、实施船闸快速检修等措施,有效提高了三峡船闸的通航能力。Since 2003 when the Three Gorges Reservoir started impounding, the regulation conditions have been changed significantly from the preliminary design, such as construction of a number of large and medium-sized hydropower stations in the upper reaches, continuous improvement on hydro-meteorological forecasting, and increased demands of reservoir dispatching in various aspects. To adapt to the new environment, from 2009 to 2012 this reservoir adopted optimized regulations such as impounding water in advance, improved control on small and medium-size floods, and floating on flood limited water level, so that its comprehensive benefits in flood control, power generation, navigation and water supply have been greatly improved. Simultaneously, ecological regulation that is practiced to promote fish breeding, expands the ecological benefit; and optimized sediment regulations are implemented, so the reservoir can remain for a long time with effective storage capacity. In addition, measures of increasing anchorage stations upstream and downstream to the Three Gorges ship lock and its rapid repair techniques are put into effect, which effectively improved its navigation capacity.
