摘　　要：采用气候学统计方法,分析了黑龙江省81个气象站1961—2003年逐日平均气温、降水量变化趋势的时空特征和气候异常特征。结果表明:黑龙江省年平均气温、降水量的变异系数和稳定性存在着季节差异;平均气温升高趋势和降水量的变化趋势在时间和空间上存在着明显的差异;平均气温、降水量的异常年份各有其特点。The temporal and spatial characteristics of the changing trend of daily average air temperature and rainfall as well as the exeeptional eharaeteristies of climate were analysed with relevant data from 81 meteorologieal stations during 1961 - 2003 in Heilongjiang Province by using the statistical method in climatology. Significant differences were found in variation eoeffieient and stability of average air temperature and rainfall for different seasons in Heilongjiang Province. There were markedly temporal and spatial differences in the heightening trend of average air temperature and in the changing trend of rainfall, and those exceptional years of average air temperature and rainfall had their own elimatie eharaeteristies.
