摘要(Abstract)：

【目的】为了使水库生态放流对策的制定与河流来水丰枯、水利部生态流量保障目标相适应，有必要对水库生态调度放流对策模型进行研究。【方法】以大凌河上的白石水库为例，选用Tennant法、Texas法、水利部生态流量保障目标(定值法)的生态流量计算结果用于生态调度，构建供水、发电、生态协调最优的生态调度模型。【结果】调度期末没有恢复汛限水位的要求，3个方法的年供水缺水量均值比有恢复汛限水位的要求减少了8.20%、20.21%、11.62%,生态供水缺水量均值减少了16.39%、14.40%、10.96%,定值法、Texas的发电量均值减少了0.90%、3.46%,Tennant法的发电量均值增加了3.73%。调度期末没有恢复汛限水位的要求，Tennant法比定值法、Texas法的水库年供水缺水量均值小19.91%、10.69%,非汛期缺水量均值小49.47%、21.17%,年发电量均值大4.25%、5.77%,汛期发电量均值大69.22%、9.20%。【结论】调度期末水库水位不要求尽量恢复汛限水位，能够提高水库水资源的利用率，以Tennant法计算的生态需水量的调度模式能够有效结合来水丰枯，实现供水、发电、生态的最优。
