Abstract: Based on daily average temperature data from 78 meteorological stations in Heilongjiang province from 1981 to 2012，the temporal and spatial variation of accumulated temperature ≥10℃ was analyzed by using five day running average and Kriging interpolation space method.The accumulated temperature zone in Heilongjiang province was rezoned by using of the 80% guaranteed rate of the accumulated temperature.The results showed that the annual average temperature increased obviously at the rate of 0.21℃/10y，and the accumulated temperature ≥10℃ increased at the rate of 83.95℃·d per 10 years from 1980s.The average accumulated temperature was 2645.39℃·d in 1981-2012.The accumulated temperature ≥10℃ increased significantly in decadal，and the accumulated temperature≥10℃ zone moved to north and east obviously.The accumulated temperature with 80% guaranteed rate was above 2300℃·d in most regions，and all zones expanded to north and east.The results could provide references for planting division in Heilongjiang province.

Key words: Climate warming, Accumulated temperature≥10℃, Kiring interpolation, Accumulated temperature division
