摘　　要：在实测资料的基础上，利用小流域设计洪水方法，结合延河77．7特大洪水进行延安城市防洪水文计算，并推求出不同设计标准的河道水面线。经分析和讨论，成果合理可靠，可供工程部门应用。Based on observed data and by the way of small basin design flood, the hydrological frequency calculation of flood protection for the Yanan city are carried out considering the extreme flood occurred in July 1977. At the same time, the water surface line along the Yanhe River is calculated with the different design stardards. It is shown by analysis and discussion that the results are reasonable and reliable, so that can be used in practice.
