| 摘 要： | 以宜昌水文站为例,针对不同时期河流生态系统对水文条件的需求,基于熵权、生态适宜性理论,构建了长江干流宜昌站近50年逐日适时划分水文指标模型,分析了流量、时间、频率、变化率等主要水文指数对河流生态流量的影响。结果表明,该方法可行。

| Abstract: | According to the ecosystem requirement of hydrology conditions in different phase and the daily flow data in Yichang gauge station nearly fifty years,the hydrology indices model is established by using entropy weight and ecological optimal theory.And then the influence of flow,time,frequency and change rate on river ecological flow are analyzed.The results show that the proposed method is feasible. |
