寒区流域水文模型及其应用研究

从影响寒区水文物理特性各要素入手,分析研究寒区特有的一些水文现象物理成因,在水文物理及冰雪冻土水文的有关理论基础上,参考非寒区流域模型的结构,建立具有物理基础的寒区概念性流域水文模型。利用黑龙江省牡丹江流域3个水文站的多年径流系列资料,对寒区产汇流的各个主要环节进行了模拟计算,得到了令人满意的计算结果,并为进一步研究寒区不同特性的区域流域水文模型奠定了基础。

Hydrological Model of Cold Zone and Its Application

Based on the different factors and hydrological physical elements in the cold zone, the paper analysed the unique physical hydrological phenomenon in cold zone. Considering the theories of hydrological physics and frozen soil and snow melting, and based on model structures in the warmer region, a conceptu- al hydrological model in the cold regions was developed. The available observations in three basins in the stream of Mudanjiang River were used to simulate and calculate the main factors relevant to runoff generation in the cold zone. It is shown by desirable results that the present findings should have an important reference value in regional hydrological model study of cold zone.
