      Ecological Runoff and Its Ecological Operation of Three Gorges Reservoir

      摘要:
      根据三峡水库宜昌站1950年~2002年逐日流量资料,在改进Tennant法和逐月频率综合法的基础上,结合次最小(大)值法、河道湿周法和RVA法,分别计算了宜昌站最小、适宜、最大生态径流和适宜生态径流阈值,借助遗传算法,建立了三峡水库生态调度模型,分析了不同水平年下的三峡水库生态调度结果,并针对四大家鱼和中华鲟开展了生态调度研究,可为三峡水库后续制定科学合理的运行调度方案,以及合理开发长江水资源,保护河流健康提供参考.
      Abstract:
      According to the daily runoff of Yichang Hydrological Station from 1950 to 2002 in Three Gorges Reservoir,the minimum,optimal and maximum ecological runoff and the thresholds of optimal ecological runoff of Yichang Station are calculated by combining second minimum (maximum) method,wet-zone method and RVA method based on improved Tennant method and monthly frequency synthesis method.Meanwhile,the ecological operation model of Three Gorges Reservoir is established based on genetic algorithm method to analyze the ecological operation results of Reservoir under different target years.The ecological operation researches are also carried out for the four major Chinese carps and Chinese sturgeon.The research results can be a scientific and reasonable operation and dispatching plan for Three Gorges Reservoir,and provides references for how to develop Yangtze River's water resources and protect river health.
