摘要:
变化环境下的流域水文情势发生了较为显著的改变，水文模型采用历史径流资料进行参数率定已然不太合适。因此，建立流域属性与水文模型参数之间的回归关系就成了参数有效估计的可行途径。本文在分析变化环境下流域水文响应的基础上，对现有流域水文模型参数区域化过程进行归纳，分别从流域物理属性选取、水文模型结构分析、回归模型结构及其参数识别和不确定性分析四个方面对国内外流域水文模型参数区域化的相关研究现状进行总结分析，最后，对流域水文模型参数区域化过程中存在的问题进行讨论。Since the watershed hydrological regimes under changing environment have been altered signifi-cantly, it is not suitable to calibrate the parameters of hydrological models using historical streamflow records. Therefore, it is practicable to establish the empirical relationships between basin characteristics and model parameters for effective parameter estimation. Based on the analysis of watershed hydrological responses under changing environment, this paper gives the basic outline of currently existing regionalized procedure of model parameters, and then summa-rizes its research status at home and abroad from four aspects respectively: selection of catchment properties, analysis of hydrological model, identification of the regional model structure and its parameters, and uncertainty analysis in the above regionalized procedures. Finally, the issues for regionalized parameters of watershed hydrological models are addressed.
