摘要
我国70%以上的地区都存在着季节性冻土,它对农业经济、生态环境等都有着巨大的影响。由于冻土的特殊性,目前并不能从本质上揭示冻土水文机理,冻土条件下的土壤水分运移规律是冻土水文模拟的重要环节。本文介绍了冻土地区水文过程的特殊性,以及目前国内外对冻土水文的研究进展,并在此基础上对冻土区水文模型的发展趋势进行了分析。
There is seasonal frozen soil area over 70% territory of China ,which has a great impact on agricultural economy and ecological environment. At present, the essential hydrologic mechanism of frozen soil has not been revealed because of its particularity. The movement law of soil moisture is an important link of hydrological frozen soil simulation. This paper introduced the particularity of hydraulic process in frozen areas and the concerned study situations at home and abroad. It also analyzed the development trend of hydrological models for frozen areas.
