| 为减轻水利工程对河流生态系统造成的不利影响，针对重要珍稀水生动物中华鲟资源的有效保护及可持续发展问题，本文在葛洲坝下游中华鲟产卵场水动力数学模型及产卵适合度评价模型的基础上，利用BP人工神经网络的学习能力构建水库调度与产卵场产卵适合度关系模型，并将关系模型嵌入葛洲坝现行的水库调度模型，获得中华鲟产卵期（10—11月）优化中华鲟产卵生境的水库生态调度模型。生态调度模型以中华鲟产卵场产卵适合度及水电厂发电量最大为双目标函数，以同期水库需满足的航运效益、水资源利用效益及水轮机运行效益为主要约束条件，通过比较相同 |

| In order to mitigate the adverse effects of hydraulic engineering on river ecosystems，and for the effective protection and sustainable evelopment of Chinese sturgeon， a relational model between the reservoir operation and the suitability of Chinese sturgeon spawning ground has been built up by BP artificial neural network，on the baois of the hydrodynamic model and spawning fitness evaluation model. By the relational model embedded in the existing Gezhouba reservoir operation model，this paper gets the eco-scheduling model for the optimization of Chinese sturgeon spawning habitats. The target functions of the ecological scheduling model compose of the largest spawning fitness of Chinese sturgeon spawning ground and the largest electricity generation of the hydroelectric power plant， and the main constraints compose of the navigation benefits， water resource use efficiency and turbine operational efficiency that should be balanced during the reservoir operation. By comparing the comprehensive benefits between ecological regulation and the current scheduling， the spawning suitability of spawning ground in ecological regulation increased 39% than in current scheduling， and meanwhile， the total generating capacity in ecological regulation reduced only 0.15%. The results indicate that the ecological regulation model can make a more appropriate hydrodynamic environment for the Chinese sturgeon， increasing the probability of their spawning and protecting the sturgeon resources effectively. |
