摘　　要：无流量资料地区径流分析计算一直是水利工程设计的研究重点之一。以浙江省无实测流量资料的中小河流域为研究对象,以参证流域逐日降雨、逐日流量为基础,优选模型参数,构建参证流域二水源新安江产流与线性水库汇流耦合模型,并以设计流域长系列面平均逐日降水资料为输入,推求设计流域逐日径流系列。结果表明,该耦合模型具有结构简单、参数物理意义明确、计算灵活快捷、拟合精度较高等优点,可适用于浙江省无流量资料地区中小河流域径流分析计算。该研究可为后续其他无流量资料地区径流分析计算提供一定的参考。The analysis of runoff in areas without flow data has always been a key focus in the design of water conservancy projects.This paper presents a coupled model for the runoff convergence in medium and small river basins in Zhejiang Province,where no flow data is available.The model uses daily precipitation data as input to infer daily runoff series.The results indicate that the coupled model has the advantages of simplicity,clear physical significance of parameters,fast and flexible computation,and relatively high fiting accuracy.It can be applied to the runoff analysis in areas of Zhejiang Province without flow data,providing valuable references for similar calculations in other areas without flow data.
