利用1971-2005年龙卷风事件资料，针对彭泽核电站评价区域内龙卷风的时空分布、地域分布、天气系统等特征，采用统计学方法进行调查和分析，结果表明：评价区域调查面积约23．58km2，涉及5省22个设区市163个县（市、区），出现龙卷风共151次，平均每年4．31次，主要发生在春夏季节的3～8月之间，且多数发生在16：00～19：OO时。龙卷风事件主要发生于长江沿岸和鄱阳湖周边的平原地区，丘陵岗地和山地很少出现。龙卷风的影响系统主要有冷锋、暖气团、静止锋、飑线和热带气旋等天气系统，表明低层暖湿、中高层干冷是龙卷风形成的基本层结条件之一。

By means of tornado materials from 1971 to 2005,according to tornadoes spatiotemporal and geographical distribution, and weather system characteristics in evaluation area of Pengze nuclear power plant, statistical methods are adopted to investigate and analyze. The results show that： the survey area is about 23.58 square kilometers,including 5 provinces, 22 cities and 163 counties. There were totally 151 tornadoes,an average of 4.31 times a year,mainly in spring summer from March to August,most occurred in 16：00-19.00. Tornadoes mainly happened around the Yangtze River and Poyang Lake,and rarely appeared in mountain and hilly area. The following weather systems can lead to a tornado generation such as cold front, warm air mass, stationary front, squall line and tropical cyclone. Both low-level warm wet and dry cold in the middle and upper air is one of the basic conditions that can cause the tornado.
