摘　　要：利用黑龙江省67个台站1961-2013年地面月总云量观测资料,采用气候趋势系数和气候倾向率方法分析了黑龙江省总云量的时空渐变特征。结果表明,近53 a,黑龙江省年平均总云量呈减少趋势,气候倾向率为-0.6%/10 a,20世纪90年代总云量减少最明显,1963年总云量最多,2001年最少。四季平均总云量均呈减少趋势,尤其在夏季。从空间分布看,黑龙江省多云区域主要位于大兴安岭、伊春、三江平原、牡丹江,少云区域位于西部地区。黑龙江省大部分地区总云量呈减少趋势。Based on the month total cloud cover of 67 stations in Heilongjiang province from 1961 to 2013, the spatial and temporal variations of total cloud cover were analyzed by using the climate tendency coefficient and climate trend rate method. The results showed that： in recent 53 years, total cloud cover was decreased in Hei- longjiang, and the chmate trend rate is -0.6%/10 a,the most obvious reduction occurred in 1990s, total cloud cover was the most in 1963,the least in 2001.Four seasons showed a decreasing trend, especially in summer. Spatial distribution of total cloud cover shows that total cloud cover is the largest in Daxinganli jiang plain,Mudanjiang, less in west Heilongjiang. Total cloud cover showed a decreasing trend Heilongjiang.
