摘　　要：应用断面径流量减去河道内生态需水量与河道外难控制利用弃水量并扣除二者间重复量的算法,利用黄河唐乃亥、花园口、利津等7个水文站断面实测和统计数据,分析计算多年平均黄河花园口、利津断面地表水可利用量分别为292.88亿～317.56亿m^3/a和258.88亿～361.24亿m^3/a。The paper analyzes and calculates the normal annual available volume of surface water of Huayuankou and Lijin cross-sections of 29.288-31.756 billion m3/a and 25.888~36.124 billion m3/a respectively by using the algorithm of cross-section runoff subtracting water demand for ecology in the channel and surplus water that difficult to be controlled and utilized beyond the channel deducting replications between the two and using the observed data and statistics of 7 hydrometric stations,including Tangnaihai,Huayuankou and Lijin of the Yellow River.
