摘　　要：以福建省67个县市2004-2010的年雷暴日观测数据与闪电定位系统监测到的雷闪次数为数据基础,对区域雷暴日与闪电监测数据的关系进行了研究。结果表明除了福建省中部区域雷暴日与闪电监测数据的相关程度较高外,总体上福建省雷暴日与闪电监测数据间的关系呈现不规则的片状分布,论文通过数学的方法证明了该片状分布是一具有稳定形态特征的区域分布,为此论文提出了片状函数的概念,用来表达不规则片状分布数据的数学特征,通过对片状函数特征的讨论,对实践中一些看似没有相关规律的数据做了可能存在片状分布规律的猜测。This paper uses the thunderstorm days and the data of lightning monitoring system in 67 cities and counties of Fujian Province to discuss the relationship between them. The result shows that, there is high correlation in the central region of Fujian Province, and besides, the relationship between thunderstorm days and the data of lightning monitoring system in Fujian Province is irregular, which shows a stretch shape distribution. The paper proves by mathematics method that the stretch shape distribution is a stability region. Therefore, the paper puts forward the concept of stretch shape function to express the mathematical characteristics of the irregular stretch shape distributive data and through discussion on characteristics of stretch shape function, the paper makes an estimation that, data that looked like no regularity may have a stretch shape distributive regularity.
