摘　　要：将石家庄市河流生态需水分为最小和适宜生态需水,其中最小生态需水可以作为近期规划年的生态需水量,适宜生态需水可以作为远期规划水平年的生态需水量;采用Tennant法进行分析表明,滹沱河黄壁庄水库站、滹沱河北中山站、沙河新乐站、磁河横山岭水库站、槐河马村水文站年最小生态需水量分别为1. 83亿、1. 56亿、0. 06亿、0. 14亿、0. 16亿m^3,适宜生态需水量分别为5. 49亿、4. 69亿、0. 57亿、0. 41亿、0. 48亿m^3;再与Tennant评价标准比较可得,研究所计算的生态流量结果能够满足河流生态目标的需求,与天然河流年内丰枯变化状态相吻合,计算结果较为合理.The ecological water demand of rivers in Shijiazhuang City is divided into the minimum and the suitable ecological water demand,of which the minimum ecological water demand can be used as the ecological water demand in recent planning year,and the suitable ecological water demand can be used as the ecological water demand in the long-term planning level year.The Tennant method is used to analyze the annual minimum ecological water demands of Huangbizhuang Reservoir Station in Hutuo River,Beizhongshan Station in Hutou River,Xinle Station in Shahe River,Hengshanling Reservoir Station in Cihe River and Macun Hydrological Station in Huaihe River are 183 million m 3,156 million m 3,6 million m 3,14 million m 3 and 16 million m 3 respectively,and the suitable ecological water demands are 549 million m 3,469 million m 3 and 57 million m 3,41 million m 3 and 48 million m 3 respectively.Compared with the Tennant evaluation criteria,the ecological flows calculated by this method can meet the needs of river ecological objectives,which are consistent with the annual changes of natural rivers in dry and wet season.The calculation results are more reasonable.
