摘要
Tennant法作为生态基流的一种计算方法在我国广泛应用。根据南渡江的独特的气候地理特征,通过引进季节修正系数,并运用中位数理论改进Tennant法。然后分别运用传统Tenant法和改进的Tenant法,对南渡江的生态基流量进行对比。通过对比分析可得:改进的Tennant法所得到生态径流量均小于传统Tennant法的计算结果,更好地反应了南渡江季节性的变化,有效的去除极端数值对计算结果的影响,对南渡江的生态环境和水资源的合理分配具有指导作用。
Tennant method as a way to calculate the ecological base flow is widely used in our country.According to the unique geographical features climate of Nandu River,Tennant method is improved by introducing season correction coefficient and using the median theory.Then the ecological base flow of Nandu River is respectively calculated by the method of traditional Tenant and improved Tenant method.Through the comparison and analysis of result show:the ecological runoff calculation result calculated by improved Tennant method is less than the result calculated by traditional Tennant method,reflected well the seasonal changes of Nandu River and removed the influence of extreme numerical calculation.It has a guiding role in he protection of ecological environment and water resources reasonable allocation of Nandu River.
