摘　　要：利用全国160站气温监测资料,分析了近60 a以来黑龙江省、东北及全国气候变化(暖)的特征。结果指出,黑龙江省、东北及全国年平均气温呈线性增加趋势,黑龙江省升温速率0.37℃/10a,远高于东北0.33℃/10a、全国0.22℃/10a的升温速率。黑龙江省、东北及全国年平均气温变化基本可分为3个阶段,第1阶段,1951-1969年计19 a,黑龙江省、东北及全国处在低温时期;第2阶段,1970-1987年计18a,黑龙江省及东北气温处于正常时段,此时全国气温仍处在气温较低时段;第3阶段,1988-2009年计22 a,无论是黑龙江省、东北还是全国均处于高温时段。黑龙江省年平均气温升幅位于全国第1位,升温1.22℃,升温第2位是内蒙,升温第3位是吉林省。Climate change of Heilongjiang Province, northeast China and the whole country was analyzed using the 60-year temperature observation data from 160 meteorological stations in China. Results show that, the climate all present a linear increase trend, among which the temperature-rising rate of Heilongjiang Province is 0.37℃/10a, much higher than the 0.33℃/10a rate of northeast China and 0.22℃/10a rate of the whole country. The annual average temperature change can primarily be divided into 3 stages. The first stage is from the year 1951 to 1969, amounting to 19 years, when all regions are in lower-temperature period. The second stage is from the year 1970 to 1987, amounting to 18 years, when Heilongjiang Province and northeast China are in the normal temperature interval, but the whole country is still in the much lower temperature interval. The third stage is from the year 1988 to 2009, amounting to 22 years, when all regions are in the high temperature interval. Heilongjiang ranks first in the rising amplitude of annual average temperature, Inner Mongllia ranks second and Jilin Province ranks the third.
