%X 在全球气温显著升高背景下，明确各区域气温变化特征具有重要意义。本文利用NCEP/NCAR近地表月均值气温资料分析1979~2020年东北黑土区年均气温以及各月气温时间变化特征。结果表明，近42年东北黑土区年均气温为2.20℃，7月为年内气温最高月份，平均气温为20.86℃，1月为年内气温最低月份，平均气温为？19.63℃。1979~2020年东北黑土区年均气温以0.31℃/10a的速率极显著升高。本研究将为明确东北黑土区气温变化提供参考依据。<br />
Under the background of significant global temperature increase, it is of great significance to clarify the characteristics of air temperature change in each region. In this paper, the NCEP/NCAR near-surface monthly mean temperature data are used to analyze the annual mean air temperature and the temporal characteristics of monthly air temperature changes in the Northeast Black Soil Region from 1979 to 2020. The results show that the mean annual air temperature in the Northeast Black Soil Region in 1979~2020 was 2.20？C, with July being the highest month with a mean temperature of 20.86？C and January being the lowest month with a mean temperature of ？19.63？C. The mean annual air temperature in the Northeast Black Soil Region from 1979 to 2020 increased at a rate of 0.31？C/10a. This study will provide a reference basis for clarifying the air temperature changes in the Northeast Black Soil Region.
