摘　　要：为探求漓江流域上游河段干支流的流量演进过程,基于该河段主要干支流上的三街水文站、灵川水文站和桂林水文站的每日实测流量数据资料,以演算出流量与实测出流量的离差平方和最小为主要判据,直接推导出了马斯京根法的河道流量演算系数C_(0)、C_(1)、C_(2)(0.37;0.62;0.01)。用所推求得到的系数模拟漓江上游河段的流量演进过程,并对该河段的流量演进过程进行了分析。结果表明:流量演算值的确定性系数为0.812,相关系数为0.940,达到了乙级标准,演算结果可靠,可为桂林市的洪水预报作业提供参考依据。In order to explore the flow evolution process of the main and tributary streams in the upper reaches of the Lijiang River Basin,the flow is calculated based on the daily measured flow data of the Sanjie Hydrological Station,Lingchuan Hydrological Station and Guilin Hydrological Station on the main trunk and tributaries of the river.The main criterion is the minimum sum of squared deviations from the measured flow,and the coefficients C_(0),C_(1) and C_(2)(0.37;0.62;0.01)of the river flow calculation of the Muskingen method are directly derived.The calculated coefficient was used to simulate the flow evolution process of the upper reaches of the Lijiang River,and the flow evolution process of this section was analyzed.The results show the certainty coefficient of the calculated flow value was 0.812,and the correlation coefficient was 0.940,which meets the Grade B standard.The calculation result was reliable and could provide reference for the flood forecasting operation in Guilin.
