Abstract:

Abstract: This paper made use of the data of 80 weather stations in Heilongjiang Province from 1961 to 2003.The climate change was comprehensively analyzed with GIS and Kriging mathematics method. And C. W. Thonthwaite method was also used to analyze the effects of climate change on boundaries of eco-geographical regions.The results showed that with the air temperature increasing and the precipitation fluctuating,the boundary between the temperate zone and the warm-temperate zone was moving toward the east and the north. The boundary between cool-temperate zone and temperate zone was significantly moving toward north. In the same time, the humid areas were changed to be semi-humid character in Xiaoxing'an Mountains region.The boundary between semi-drought regions and semi-humid regions did not change in the southwest. However the area of the semi-drought region in the middle of Sanjiang Plain increased to some extent.
