摘　　要：相对湿度是气候农业资源的一个重要方面,与温度、降水等气候因子一起对农业有深刻的影响,根据黑龙江省1961-2011年间各气象站点逐日相对湿度气象资料,运用Mann-Kendall突变性检验等方法对黑龙江省平均相对湿度全年、四季、年代际的变化进行特征分析,结果表明:近51年来黑龙江省平均相对湿度波动中呈微弱下降趋势,下降速率为0.07%/10a,这期间共发生3次突变,每次突变后都呈现不同的变化;黑龙江省四季相对湿度变化趋势除春季呈升高外,其他季节均呈减少趋势;相对湿度全年和四季的年代际变化各不相同,其中,全年、夏季、秋季、冬季相对湿度随年代际呈减少趋势,春季呈增加趋势,年代际间波动性变化不大。Relative humidity,which is an important aspect of agricultural climate resources,along with climate factors,such as temperature,precipitation,has a profound influence on agriculture according to the daily weather meteorological data from 1961 to 2011 in Heilongjiang province. With the annual average relative humidity in Heilongjiang province,we found the average relative humidity in Heilongjiang province fluctuated in nearly 51 years in,the declining rate is 0. 07% / 10 a,during this period,a total of three mutations present different change after each mutation; For the four seasons in Heilongjiang province,the relative humidity change trend is higher. The decadal variability of relative humidity throughout the year is not identical among the spirit,the summer,the autumn and the winter. Relative humidity with the decadal data showed a trend of decrease,the volatility between the decadal change is not big.
