摘　　要：为发挥水库在水资源开发利用与河流生态环境问题之间的协调作用,以丹江口水库为例,探讨了综合利用水库生态库容划分方法。以丹江口水库下游襄阳和仙桃为控制断面,采用Tennant法计算下游河道生态流量的参考值。在考虑丹江口水库的防洪、生态、供水、调水、发电、航运等综合任务和汉江中下游水量联系的基础上,建立了综合利用水库的生态库容优化模型,拟定了4组调度规则,应用自适应遗传算法和模拟调度方法进行求解。计算结果表明:设置生态库容后的调度图能较好地满足控制断面对生态流量的需求,获得较佳综合利用效益。In order to coordinate the role of reservoirs in water resources development and river ecosystem protection,a scheme for designing ecological storages were presented and applied on Danjiangkou reservoir.Tennant Method was used to calculate reference values of ecological flow in Xiangyang and Xiantao,two control sections downstream of Danjiangkou reservoir.Then an optimization model for ecological storage were established based on an integrated consideration of the reservoir’s multi-function,including flood control,ecological water demand,water supply,water transfer,power generation and navigation.Finally,solutions were obtained by integrating Adaptive Genetic Algorithm（AGA） with scheduling simulation technology under the background of four operation rules respectively.Results indicated that the operation charts with ecological storages could meet the demand of ecological flow in the control sections with a superior comprehensive benefit.In addition,optimize-simulate technology was approved to be a viable approach for the ecological storage design.
