increased power generation to cope with the electricity demand under the ice and snow disaster in 2008.It supplemented freshwater to repulse saline water in dry season in 2014,and rescued the “Star of the East”, who is overthrown by a tornado in 2015. Also, it carried out compensation regulation in flood control for the lower reaches of Yangtze River in 2016 and 2017.With these rich experiences in emergency dispatching, the TGP reservoir has gradually formed a complete emergency response system. In the emergency dispatching, the TGP reservoir takes the protection of social benefits as the goal, and minimizes the loss with systematic and efficient management method. The main measures are as follow, the reservoir management organization has established a coordination system with flood control department, shipping department, land resources office and other departments, and share the information with each other; Also, enhancing operation situation analysis and premeditated simulation of accident, to prepare the emergent schemes in advance; Thirdly, building the emergency management system: Distributing the responsibility according to the event types, and forms a complete emergency command mechanism; Also, responding to events in a hierarchical manner, clear the workflow with conferences at different levels, to find the solution to deal with emergency events efficiently. In order to further improve the emergency system, it records the event and summarizes the experience after solving the problem. Through the emergency dispatching for special events, the TGP reservoir improves its ability to deal with emergencies and brings remarkable social benefits. Also, in the cooperation of public activities, its political and public welfare value is highlighted. 6. SUMMARY AND PROSPECT This paper focuses on the analysis of reduced precipitation, which is caused by climate change. In view of this, it put forward the optimization scheduling method: utilization of flood resources in later flood season and water level elevation in stages in water storage period based on the hydrological forecast, and the modified scheduling strategy are proved effective and applicable by practice. Furthermore, it sums up the TGP Reservoir’s emergency management measures for disaster events caused by extreme weather, and demonstrates the positive significance of the emergency dispatching system. Meanwhile, with the construction of the reservoirs in upstream and the accumulation of reservoir operation experience, the accuracy of runoff prediction can be improved based on the information sharing in the basin, so as to coordinate the operation and optimize the storage and discharge structure in reservoir groups. But the operation time of the reservoir in upper reaches is relatively short and the operation experience is not very enough. The joint operation of large reservoir groups in climate change environment needs further study and the optimization potential needs further exploring in the future, so as to better cope with the climate change and greatly play the role of overall coordination in the Yangtze River basin. 249
