Based on the daily air temperature data from eighty meteorological stations in Heilongjiang Province from 1961 to 2013, the spatiotemporal variation characteristics are analyzed with the methods of the linear regression method, Mann - Kendall test method, moving T-test technique and wavelets analysis method. The results show that annual mean temperature is 2.57 ℃ with increasing rate of 0.35 ℃/(10 a) in recent 52 years. Seasonal mean temperature, maximum temperature and minimum temperature all exhibit increasing tendency, but the warming trend and change of minimum temperature is very obvious. The increase of minimum temperature in winter is more than in other seasons and its increasing rate is 0.59 ℃/(10 a). From the space change, the most obvious warming scope distributes in the Da and Xiao Xing'anling Mountains. Both annual mean temperature and maximum temperature have an abrupt change in 1988 and minimum temperature has an abrupt change in 1981. Annual mean temperature has an 8 a change cycle. The results would contribute to understand the temperature variation and to improve the ability to adapt the climate change for local government.
