| 摘 要： | 本文对同德气象站50a来冬季冻土层的变化作了深入的分析,结果表明,当地多年平均冻土层呈递减趋势,其中,1987年~2006年递减趋势最为明显。通过对影响冻土层变化的气象因子进行统计分析,指出气温是影响冻土层变化的首要因子,由于气温存在升高的趋势,导致冻土层必然呈下降状态。

| Abstract: | Palit weather station 50 years changes in the winter permafrost depth analysis,the results show that the local annual average decreasing trend of permafrost,which,in 1987-2006 descending trend was most pronounced.Some effects of permafrost changes in the statistical analysis of meteorological factors that affect the permafrost temperature changes is the primary factor,as there is rising trend in temperature,resulting in an inevitable downward state of permafrost. |
