摘　　要：针对1979~2014年南北极海冰重要物理参量变化及其与全球气候之间关系的研究空缺问题,进行了南北极海冰长时间序列变化特征研究。该文利用1979~2014年被动微波辐射计海冰密集度产品基于线性倾向估计方法分析36年来南北极海冰密集度变化;由海冰密集度产品得到南、北极海冰范围,分析年际及月际变化,结果显示北极海冰范围明显减小,南极海冰范围略微增大;结合南方涛动指数（Southern Oscillation Index,SOI）和全球平均海平面高度（Global Mean Sea Level,GMSL）,指出海冰范围的突变时间,并得出GMSL变化与海冰范围的关联,南极海冰范围变化与SOI之间存在着明显的相关性,GMSL逐年上升,与海冰范围变化呈现显著的负相关。In this paper, Antarctic and Arctic sea ice long sequence variations have been studied. 1979 - 2014 sea ice concentration product from passive microwave radiometer were linear trend estimated, and Antarctic and Arctic sea ice extent calculated from sea ice concentration product were analyzed annually and monthly. Experimental results show that Arctic sea ice extent has significantly reduced and has a slight increase in Antarctic. Sea ice mutations were pointed out combined with Southern Oscillation Index （SOD and the Global Mean Sea Level （GMSL）,and correlation between sea ice extent and GMSL were obtained. Results also show that Antarctic sea ice extent has an evident correlation With SOI, and the significant rise for GMSL has obvious negative relation with sea ice extent variation.
