摘　　要：本文以挠力河为例,基于菜嘴子、保安、宝清、红旗岭四个水文站1956—2012年的月径流数据,运用逐月频率法、改进Tennant法计算年内适宜生态径流及生态需水过程,得到其年内适宜生态需水阈值,最终获得四站完整的生态径流及生态需水过程。研究结果表明,各站所在河道内的生态需水量计算方案结果均较为理想,各月生态需水量平均保证率为60.2%,河道内生态状态很好。In this paper, Naolihe River was selected as an example. Based on the monthly runoff data of the 1956--2012 in four hydrological stations of Caizuizi, Baoan, Baoqing and Hongqiling, this paper uses the monthly frequency method and the improved Tennant method to calculate the annual suitable ecological runoff and ecological water demand process to get the threshold of the annual ecological water demand, and finally get complete ecological runoff and ecological water demand process of the four hydrological stations. The results show that the calculation scheme of ecological water demands in each river that hydrological station in is ideal, the average guarantee rate of the monthly ecological water demand is 60.2%, and the ecology in the river is pretty good.
