| 摘 要： | 本文利用多源遥感数据从不同空间尺度对2004年至2012年间北极地区新冰进行了提取并对其范围变化进行了分析。统计分析结果表明,北极海冰总体覆盖面积与北极近地表气温的变化呈反比;新冰覆盖面积的变化与海冰总面积的变化相比较缓慢;北极各个区域新冰覆盖范围的变化与各区域近地表温度的变化有较大的关联。

| Abstract: | Sea ice is the most active and unstable component in polar region that its change is significant for the investigation of regional and global climate and environmental change. In this research, the Arctic sea ice and new ice extent from 2004 to 2012 were extracted and their time series changes were analyzed by using multi-source remotely sensed data. The results indicate: there was an inverse relationship between the sea ice extent changes and the near surface air temperature variations;the new ice extent changes were inversely proportional to the sea ice extent changes;the regional new ice extent changes and the near surface air temperature variations had a close relationship. |
