利用1961～2010年抚州市逐日降水资料，对抚州市年降水量进行时空分布特征分析，结果表明：年平均降水量空间分布极为不均，年平均降水量最少为1692．5 mm，最多为1979．1 mm，东部多于西部，北部多于南部；降水量存在着明显的年际、年代际差异，总体呈增加趋势，平均以25．3 mm/10 a的速度增加；降水量暖季多冷季少，年降水量主要集中在汛期4～7月，占年平均降水量的54．9％；EOF分析表明，抚州市年降水量空间分布主要呈现总体一致型，共同的天气影响系统和环流形势是其决定性因素；但也存在着南北与东西分布差异，这是由影响系统强弱、移动路径与地形等因素共同造成的。

Based on the daily precipitation data of Fuzhou city during 1961~2010, the spatial and temporal distribution char-acteristics of annual precipitation in this city were analyzed .The results showed that the spatial distribution of annual average precip-itation was extremely uneven , the annual average precipitation varied from 1692.5 mm to 1979.1 mm, and it was more in eastern and northern part , while less in western and southern part .The precipitation existed obvious interannual and interdecadal differ-ences, and it generally showed an increasing trend with the average increasing rate of 25.3 mm/10 a.The precipitation in warm sea-son was more than that in cold season , and the precipitation from April to July was the most within a year , accounting for 54.9%of the annual average precipitation .EOF analysis indicated that the spatial distribution of annual precipitation in Fuzhou city was gen -erally consistent , which was decided by the common weather affecting system and circulation situation ;there was also differences in the spatial distribution of annual precipitation between the north and the south , and between the east and the west , which was caused by the intensity of the affecting system , moving path and geography together .
