摘　　要：通过对两江水电站产流方式的分析,表明该流域地处湿润和半湿润地区,雨量较充沛,降雨总产流量主要决定于前期土湿和降雨量的多少,属蓄满产流区,应用降雨径流预报方法是合适的。在此基础上阐述了降雨径流要素的计算方法和降雨径流相关图建立,并介绍了具体的降雨径流预报步骤。Through analysis of runoff mode of Liangjiang hydropower station, the analysis result shows that the river basin is located in the humid and semi-humid area with the abundant rainfall, the total rainfall runoff amount is mainly depend on the antecedent soil moisture and the rainfall amount, the runoff mode of the area is belong to the runoff yields under saturated storage, therefore, the rainfall-runoff forecast method is suitable in the area. And then the paper elaborates the calculation method of the rainfall-runoff factors and the determination of the rainfall-runoff correlation diagram, and introduces the specific steps of rainfall-runoff forecast
