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 catch- ment 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. Keywords Regionalized Parameters, Watershed Hydrological Model, Changing Environment
