【Abstract】 Both the climatic feature of cold region and the hydrologic characteristics of the frozen soil therein are analyzed. Based on the revelation of the dynamic law and characteristics of the soil moisture during the frozen period, the runoff producing mechanisms different from those of the non-frozen regions and periods and the related rainfall-runoff relationship are discussed, and then the improvement on model for the stored-full runoff applied to the cold region is suggested. The actual data obtained from the study and the corresponding analysis method lay a better basis for both the hydrologic forecast and the hydrologic computation for cold region.更多还原
