摘要
分析了寒冷冻土地区(以下简称寒区)的气候特点和冻土水文特性,在揭示冻土期土壤水分动态规律和特点的基础上,探讨了不同于无冻地区和无冻期的产流机制和相应的降雨径流关系,对寒区应用蓄满产流模型提出了改进意见,文中提出的实际成果资料和分析方法为寒区水文预报和水文计算提供了依据。
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.
