Abstract:
利用日气温观测值计算了青藏铁路沿线7个主要气象站1966-2004年的年冻结与融化指数，分析了这些指数的统计与分布特征，并应用两种趋势检验方法非参数Mann-Kendall检验法和简单线性回归法分析了这些台站年冻结与融化指数的变化趋势。结果表明，青藏铁路沿线多年平均冻结指数大致分布在95~2300oC·日之间，多年平均融化指数大致在630~3250oC·日之间。7个站点的冻结指数均呈减少趋势，其线性倾向率分布在-16.6~-59.1oC·日/10a之间；融化指数均呈增加趋势，其线性倾向率分布在19.8~45.6oC·日/10a之间。MK趋势检验的结果显示，除格尔木表现出微弱的减少趋势外，其他站点都呈现了0.05水平下的显著减少趋势；年融化指数除格尔木和沱沱河表现出弱增加趋势外，其他5个台站都显示出了0.05水平下的显著增加趋势。简单线性回归方法得到的趋势结果与MK趋势检验结果相一致。
