Abstract:

The ecological operation management of the Three Gorges Reservoir is a multiobjective dynamic decisionmaking process,and also a worldwide problem.Based on the analysis of ecological operation complexity and management uncertainty,the paper brought forward the basic concept of ecological operation adaptive management and its theoretical framework.The adaptive management needs were discussed in the Three Gorges Reservoir by this theory,and five aspects demand were concerned,including integrated ecological flow in the middle and lower reaches,aquatic resource protection,water environmental protection,drought and water supply,and wetlands protection.By continuous monitoring,environment evaluation and adjustment,the platform for all departments and basinwide stakeholder participating,consulting and communicating was established to achieve the maximum comprehensive benefit of the reservoir.Given the experimental stage characteristics of the Three Gorges Reservoir,the lagged impact of the ecological environment,economic development,social transformation,and the awareness of environmental consciousness,adaptive management objectives need to adjust itself to the demands of ecological operation accordingly
