摘要
参数区域化方法是解决资料缺乏地区水文模拟和预报的有效手段,主要包括回归法、空间邻近法和属性相似法三类方法,可将有资料流域的水文模型参数移用到资料缺乏流域。首先回顾了区域化方法的基本原理和应用方法,并分析了三类主要区域化方法的适用性。从流域特征因子、水文模型及参数、不确定性探讨三个方面综述了区域化方法的研究进展。分析发现,当前区域化方法缺乏完善的理论基础,流域特征因子选择存在主观性,水文模型及参数的适用性方面研究不足。最后展望了未来的研究重点:(1)多维度适用性比较;(2)水文过程和参数的空间分布规律;(3)参数的尺度问题;(4)参数区域化的不确定性问题。
Parameter regionalization methods are an effective tool to solve hydrological modeling and forecasting in ungauged basins.They mainly include three types of methods:regression method,spatial nearest neighbor method,and attribute similarity method,which can transfer the hydrological model parameters of the gauged basin to ungauged basin.Firstly,the fundamental principles and application method of these regionalization methods were reviewed,and the applicability of these regionalization methods was analyzed.The research progress of regionalization methods is reviewed from three aspects:basin characteristics factors,hydrological models and parameters,and uncertainty.The analysis reveals that the current regionalization method lacks a sound theoretical basis,the selection of basin characteristics factors is subjective,and the applicability of hydrological models and parameters is not sufficiently studied.Finally,the future research emphases were prospected:(1)multi-dimensional applicability comparison;(2)spatial distribution pattern of hydrological processes and parameters;(3)scale issue of parameters;and(4)uncertainty of regionalization.
