摘　　要：针对环境保护和能源开发之间的矛盾,在分析水电能源系统生态环境的基础上,基于综合指数法思想,建立了动植物生态用水、工农业生活用水、污染净化用水等生态指标,配合水电站发电、灌溉、防洪效益要求,建立了水电能源生态系统的模型,并分别研究了在非固定生态指标和固定生态指标的条件下,水电站的运行状况。仿真结果表明,在非固定指标状况下运行时,10~20 s由于水位降低和一定的波动导致指标的下降和波动;20~30 s水量较多,对生态环境有利,指标接近1;30~40 s小旱,但是由于配水比较合理,指标也接近1;40~50 s大旱期间,生态水量不足,指标最低为0.5。在固定生态指标状况下运行时,生态指标固定为1、0.95、1、1、0.7、1对应6个阶段,输出结果与预期数据基本一致。综合指数思想在建模仿真中的应用是科学、合理并且可行的。同时,所建立仿真模型对解决水电站的经济运行和环境保护之间矛盾的具有重要的理论与实践双重意义。On the basis of analysis of hydropower ecological environment and the comprehensive index method,the ecological indicators including wildlife and ecological water use, industrial and agricultural water use and pollutants purification water use. were established. In addition,a model of ecological system incorporated with the benefits of electricity generation,irrigation and flood control was developed. Furthermore,the simulative study was conducted with emphasis on operation conditions of the power station in non-fixed and fixed ecological index conditions respectively. The results of the study indicated that the experimental outcome was consistent with the actual condition, the comprehensive index method applied to the simulative model was trustworthy. To cope with the contradiction between environmental protection and hydropower developing the simulation was proved useful.
