Abstract:

多年冻土是复杂地气系统的产物,以升温为特征的气候变化不可避免地对其产生影响.基于青藏铁路沿线8个天然场地2006-2011年的地温监测资料,分析了气候变化背景下,多年冻土升温特征及上限变化规律,并对低、高温冻土的变化特征进行了对比分析.结果表明2006-2011年监测期间,铁路沿线多年冻土正在经历明显的升温趋势,上限附近和15m深处平均升温率分别为0.015℃·a-1和0.018℃·a-1,其中,低温冻土区在上述两个深度处升温均比高温冻土区显著;多年冻土上限深度也表现出一定的增深趋势,平均增深速率为4.7cm·a-1,其中,高温冻土区增深速率大于低温冻土区.低、高温冻土对气候变化的响应表现出了较大差异.同时,受局地因素的影响,不同区域在升温和上限增深上也存在一定差异.
