| 摘 要： | 为了保护引水式水电站大坝与厂房之间减水河段的生态环境,需要确定河道最小生态需水量,以反映河道特征的差异.以湖南省一些典型引水式水电站下游减水河段为例,应用改进的湿周法计算了河道最小生态需水量,并通过单变量影响分析,研究河道最小生态需水量的影响因素；以幂函数对最小生态需水量与各单变量的关系进行了拟合分析,得到了合适的最小...

| Abstract: | For the protection of the ecological environment of the flow reduced river reach between dam and power station of diversion hydropower,the minimum ecological flow should be determined,so it can reflect the differences of river channel characteristics.By taking some typical diversion hydropower stations as examples,the minimum ecological flows are calculated by improved wetted perimeter method and then the influential factors of the minimum ecological flow are studied through single argument analysis;the rel... |
