摘要: 本文首先用EOF迭代方法恢复了缺测的0.8 m和1.6 m地温资料,然后分析了O.8 m和1.6 m地温的持续性和振荡特征。对前10个主成份的分析结果表明:0.8 m和1.6 m地温分别具有3-5个月左右的持续性;0.8 m地温距平和1.6 m地温距平存在显著的12个月左右和大于70个月两种尺度的周期振荡,对0.8 m地温距平,这两种尺度的周期振荡能够解释总方差的24.4%和20%;对1.6 m地温距平,两者分别解释总方差的32%和27.7%。

Abstract: First,by using iterative EOFs expansion,the data of soil temperatures in 0.8m and in 1.6m are,retrieved,then the persistence and the characteristics of oscillation are studied.Results show that:there are durations of 3-5 months on soil temperature in 0.8 m and about 6 months in 1.6 m,significant periodic oscillations of about 12 months which attribute 24.4% and 32% to total variance on soil temperatures in 0.8m and 1.6m respectively.The spectral variance of longer periodic oscillation is higher in 1.6m than that in 0.8m.But the spectral variance of shorter periodic oscillation is lower in 1.6 m than that in 0.8 m.
Key words: Soil temperature    Persistence    Oscillation characteristic
