摘要
根据我国北方地区径流特征及供水水库调度的实际需求,构建了供水水库多目标生态调度模型。模型将下游生态需水过程分为最小生态需水及适宜生态需水两个等级,要求枯水期水库放水过程能够满足河流最小生态需水要求,确保下游生态不退化;丰水期放水过程贴近适宜生态需水过程,为下游提供良好生境。基于该模型,采用自适应遗传算法,对承德双峰寺水库生态调度问题进行了优化求解,结果表明该模型能够对北方供水水库生态调度决策提供支持。
A multi-objective ecological operation model of water supply reservoir was developed according to the runoff characteristics and practical demand of reservoir operation in North China. The ecological water requirement of the downstream river was divided into two levels in the model： minimum ecological water requirement and suitable ecological water requirement. The discharge process of reservoir in the low flow period should meet the minimum ecological water requirement in order to sustain the ecological environment in the downstream,and the discharge process of reservoir in the high flow period should meet the suitable ecological water requirement in order to provide suitable habitat in the downstream. The multi-objective ecological operation model was applied to optimize the ecological operation in the Shuangfengsi Reservoir using adaptive genetic algorithm. The resuits showed that the model can provide technical support for the ecological operation of water supply reservoir in North China.
