Abstract: In order to study climate characteristics of the Greater Khingan Mountains, by using a linear regression equation and the linear trend method, the author studied the on-site monitoring data of Genhe of the Greater Khingan Mountains in Inner Mongolia from 1981 to 2010, analyzed the changing rules of temperature, precipitation, humidity, sunshine hours, wind velocity and other meteorological factors in the region and their relationship with the global climate change. Results showed that, under the trend of global warming, Genhe of the central Greater Khingan Mountains was keeping with the trend of temperature increase, precipitation decrease and the increase of sunshine hours. The meteorological factors had some corresponding relationships with global climate change. The results also indicated that the surface temperature growing trend (0.42℃ per 10 years) in the past 30 years in Genhe was much higher than the national average, and the temperature increasing trend was obvious.
