Surface of the earth temperature of the earth caused phenomenon that rise and is global warming as greenhouse
gas concentration into waiting by continuous discharge of greenhouse gas increases since passing industrial
revolution. While gravity about climate fluctuation is risen worldwide, place that can diminish successively
biggest surface of the earth change by global warming is high latitude area of polar regions. This study observed
distribution of vegetation to confirm change of tundra-taiga boundary. Tundra-taiga boundary is used to observe
the transfer of vegetation pattern because it is very sensitive to human activity, natural disturbances and climate
change. The circumpolar tundra-taiga boundary could observe reaction about some change. Reaction and
confirmation about climate change were definite than other place. This study used Leaf Area Index(LAI) 8-Day
data in August from 2000 to 2009 that acquire from Terra satellite MODerate resolution Imaging
Spectroradiometer(MODIS) sensor and used Köppen Climate Map, Global Land Cover 2000 for reference data.
This study conducted analysis of spatial distribution in low density vegetated areas and inter-annual / zonal
analysis for using the long period data of LAI. Change of LAI was confirmed by analysis based on boundary
value of LAI in study area. Development of vegetation could be confirmed by area of grown
vegetation(730,325km2 ) than area of reduced vegetation(22,372km2 ) in tundra climate. Also, area was
increased with the latitude 64°N~66° N as the center and around the latitude 62° N through area analysis by
latitude. Vegetation of tundra-taiga boundary was general increase from 2000 to 2009. While area of reduced
vegetation was a little, area of vegetation growth and development was increased significantly.
