The climate warming has been accelerated for dozens of years in the Arctic. However, enough studies are not done whether it is a source areas releasing carbon or a sink areas absorbing carbon in the Arctic. We established the reference sites for the vegetation change considering to be affected by the climate warming in Spitsbergen Island and Ellesmere Island. We investigated topography, edaphic features, analyses of air and satellite photographs, biological diversity, vegetation pattern and carbon cycle process, and evaluated an ecosystem change with special references with vegetation and carbon cycle influenced by the climate warming.
