中国极地大地测量学十年回顾:1996—2006年

Ten Year's Progress of Chinese Polar Geodesy:1996-2006

回顾了近10年来我国南北两极大地测量学在GPS、重力、验潮及合成孔径雷达干涉测量等方面的研究进展。具体介绍了以长城站、中山站和黄河站3个GPS观测站为依托,开展的板块运动、卫星定轨及极区大气环境监测方面的研究;GPS在埃默里冰架、格罗夫山及Dome A考察中的应用研究;长城站的高精度绝对重力及相对重力测量;中山站自动验潮站的建立;及合成孔径雷达干涉测量在南极内陆冰盖的应用研究等。

Ten year＇ s progress of Chinese polar geodesy from 1996 to 2006 is summarized. The research on plate motion, orbit determination, and atmospheric monitoring including ionosphere and troposphere, etc. was performed from the GPS data of Great Wall Station, Zhongshan Station and Yellow River Station. GPS was also applied in Amery ice shelf, Grove Mountains and Dome A expeditions. During the 2004-2005 austral summer season, the absolute gravity and relative gravity were measured at the Great Wall Station. The tide gauge was set up in Zhongshan Station in 2000. The SAR interferometry was applied to build the DEM of ice sheet and to monitor the ice flow in the polar region.
