Abstract:

The upcoming IPY initiated by ISCU and WMO in 2007 will bring a series of ambitious scientific activities of polar regions. This paper discusses the background of the IPY scientific plan and introduces its five topics grouped by ICSU PG. From analyzing the topics, it is obvious that the rapid change of environment in polar regions will be focused on by scientists in the world. IPY 2007/2008 will address an international and multi disciplinary scientific program with intensive observations and new sensing technologies. It will offer Chinese scientists a good opportunity to extend international collaboration research and expedition with other nations.
