中文摘要：
传统的水库调度方式，未考虑生态环境的需求，将导致生态系统的退化，不符合可持续发展的指导思想。本文明确定义了生态库容，阐明生态库容的必要性。以汉江中下游为例优先考虑生态需水的要求，应用自适应遗传算法对丹江口水库调度图进行优化并绘制生态调度线，确定了丹江口水库的生态库容，为生态友好型水库调度理论的应用提供了理论基础。
英文摘要：
Bio-environmental demands are rarely considered in traditional reservoir operation. This would probably lead to degradation of ecosystem. In this paper, ecological storage is clearly defined and its necessity is demonstrated. In the optimization of operation curve for the Danjiangkou reservoir, its ecological water demand is prior considered and an AGA method is adopted, and its ecological storage is determined with the method of ecological operation curve. This provides a theoretical basis for bio-environment-friendly reservoir operation.
