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.
