摘要
河流生态流量确定是近年来国内外研究的一个热点。文章选取当前国内外通用的研究方法,如Tennant法、最枯月平均流量法、Q50-Q90法、Lyon法、Tessman法、Texas法对阿什河生态需水量进行分析研究,并结合阿什河水系水文年特征、河流年内径流特点,对上述6种方法的计算结果进行分析,结果表明Tennant法计算简单,且适用于北温带河流生态需水和常年性河流,故推荐此方法作为阿什河流域生态流量的计算方法。研究结果可为区域水资源利用规划提供依据,对维护河流生态系统健康也具有重要意义。
The determination of river ecological flow has been a hot spot in domestic and foreign research in recent years.Combined with the hydrological characteristics and the annual runoff characteristics of the Ashi River,the Tennant method,most withered month average flow method,Q50-Q90 method,Lyon method,Tessman method and Texas method were chosen to calculate the ecological basic flow of the Ashi River.The results shows that the Tennant method is simple to calculate,and it is suitable for the ecological water requirements of rivers in the northern temperate zone and perennial rivers.This method is recommended as calculation method of ecological base flow in Ashi River Basin.The research results can provide a basis for the planning of water resources utilization in the Ashi River,and are also of great significance for maintaining the health of the river ecosystem.
