Abstract:

利用1981-2010年黑龙江佳木斯气象站40~320cm逐月平均地温观测资料,研究了三江平原地温变化规律、气候突变、异常年份及冻融特征等.结果表明40~320cm年平均地温呈极显著升温趋势,升幅为0.496~0.574℃·(10a)-1,其中夏季升幅最大;月平均地温呈波形变化,振幅随深度增加而减小;1月随着深度的增加地温逐渐增大,7月地温随深度增加而减小,维持正梯度.除秋季40cm和80cm,冬季320cm平均地温变化相对平稳,未出现地温突变现象,其他各层年、季平均地温均发生了突变;40cm和80cm年平均地温在1981年出现了异常偏冷,320cm年平均地温在20世纪90年代末出现了异常偏冷,40cm和160cm年平均地温在2004年出现了异常偏暖;80cm土壤较40cm冻融时间出现晚,冻结期缩短18d左右,土壤的冻结过程比消融过程要快.
