摘　　要：桂江是流经桂林市的主要河流,也是旅游的黄金水道,准确地推算出桂江桂林城区至平乐县城河段各个水文站断面的水量显得尤为重要。本文用区间水量平衡法、径流模数法、径流系数法等3种方法计算桂林(三)水文站、阳朔水文站和平乐(三)水文站的流量数据,与实测流量数据对比,选出最优法,为桂江流域水量计算提供技术支撑。Guijiang River is one of the major rivers running through Guilin City, and is also the golden waterway for tourism, so it is very important to accurately calculate the flows through the various hydrological stations located on the Guijiang River section between Guilin downtown and Pingle County. The flow data of Guilin(Ⅲ) hydrological Station, Yangsuo Hydrological Station and Pingle(Ⅲ) Hydrological Station were calculated by three methods including interval water balance method, runoff modulus method and runoff coefficient method. The calculation results were compared with the actual measuring data so as to select the optimum method, provide technical support for flow calculation of Guijiang River basin.
