近年来,南极冰架发生较多消融、崩解等现象。利用已有的1997年和2000年的Radarsat全南极海岸线产品、2003/2004年和2008/2009年的MODIS全南极海岸线产品,以及基于2006年、2012年和2015年MODIS影像提取的海岸线,共7期数据,对南极Ross,Filchner-Ronne和Amery三大冰架前端的变化进行了分析,以变化面积、累积变化量(Shoreline Change Envelope,SCE)和净变化量(Net Shoreline Movement,NSM)3个指标来评估冰架前端的变化。结果表明,1997—2015年,Amery冰架一直呈现增长趋势,前端大部分区域往外延伸20~25 km,增长面积达3.03×10³ km²;Ross冰架和Filchner-Ronne冰架在发生崩解后受上游冰川推进作用仍不断向外增长,但增长面积小于崩解退缩面积,冰架面积分别减少9.39×10³ km²和5.86×10³ km²,冰架崩解区域前端退缩最大达到53 km和39 km。

In recent years, melting and calving happen in the Antarctic ice shelves. In this paper, seven periods of coastlines were applied to provide an analysis of the ice front changes of Ross, Filchner-Ronne and Amery ice shelves with the inclusion of 1997 and 2000 Radarsat products, 2003/2004 and 2008/2009 MODIS products and 2006, 2012, 2015 coastline which were extracted from MODIS images. Change area, SCE (Shoreline Change Envelope) and NSM (Net Shoreline Movement) were applied to analyze the variation of the ice shelf front. The results shows that, the ice front of Amery ice shelf has advanced since 1997 and the total outward extension distance of the ice front was about 20 to 25 km while the advance area reached 3.03×10³ km². Ross ice shelf and Filchner-Ronne ice shelf continued to advance after ice calving events under the driver action of glacier. However, the advance area was less than the retreat area and the net change area is respectively -9.39×10³ km² and -5.86×10³ km². The retreat distance of the collapse area were up to 53 km and 39 km in the two biggest ice shelves.
