| 摘 要： | 对新疆41 a(1961/1962-2001/2002年)冬季平均冻土深度、最大冻土深度、土壤10 cm深度封冻时段资料分析表明,随着全疆气候的变暖,各地的平均冻土深度、最大冻土深度趋向变浅,土壤封冻时间缩短.尤其是1986年以后,暖湿化特征十分明显,冻土深度和封冻时间变化更为显著.最大冻土深度南、北疆分别在1982/1983年和1986/1987年冬季发生了明显的突变.

| Abstract: | In this paper,the average and maximum depths of seasonal frozen soil and the frozen duration of soil at 10 cm deep in Xinjiang during the 40-year period of 1961-2002 are analyzed.The results show that the average and maximum depths of seasonal frozen soil decrease and the frozen duration of soil becomes short under climate warming in Xinjiang.Such changes become more significant after climate warming-wetting since 1986.A significant mutation of the maximum depth of frozen soil occurred in both south Xinjiang and north Xinjiang in the mid-1980s. |
