摘要:

摘 要:利用黑龙江省80个气象站点1961—2003年的逐日观测资料,采用克立格法(Kriging)和地理信息系统(GIS)等技术,分析黑龙江省43 a来的气候变化情况,并按照桑斯维特(C.W.Thonthwaite)气候分类法,探讨气候变化对黑龙江省生态地理区域界限的影响。结果表明:在气温增高、降水量波动变化的背景下,黑龙江省温带与暖温带的热量界限发生了北撤和东移,寒温带与温带的热量界限发生了大幅度的北撤;分布于小兴安岭北部具有湿润气候特征的地区转变成半湿润的气候特征; 黑龙江省西南部半干旱区与半湿润区界限并无明显变化,但在三江平原中部地区半干旱区面积有所扩大。

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.
