摘　　要：利用福建省气象局67个站点1961~2006年逐月降水数据,对46年来福建省降水时空分布特征进行分析。结果表明,近半个世纪福建省年降水量呈增加趋势;增大最明显的是夏季,其次为春季和冬季,秋季降水量却呈减少趋势;特别是2000年之后的降水量变化幅度非常大,说明近几年发生极端天气的概率会大大加强。46年来福建省沿海地带降水量总体上呈增加趋势,增加最明显的地带是在福建省南部泉州地区,其次为东北宁德地区,西北山地及西南地区也略显增加,而在福建省中部三明盆地的永安、大田、九仙山地区降水量则表现出明显的降低。By using monthly precipitation data in 67 stations of weather bureau during 1961-2006,the temporal and spatial distribution characteristics in Fujian Province in recent 46 years were analyzed.The results showed that the annual precipitation of Fujian Province indicating increased trend;the most obvious increasing season was summer,next were spring and winter,while the precipitation of autumn showed decreasing trend.The variation amplitude after 2000 was large,illuminating probability of extreme weather is stronger.The precipitation in seaboard of Fujian Province in recent 46 years showed increasing trend,the most obvious region is Quanzhou,and then is Ningde,the precipitation in northwest mountain and southwest region is also increasing slightly,while rainfall in Yongan,Datian and Jiuxianshan showed obviously decreasing trend.
