利用1971～2010年武当山风景区周边十堰、丹江口和房县3个气象观测站雷暴资料,通过数理统计、小波变换和M-K分析,讨论了武当山景区雷暴气候变化特征,结果表明,40年雷暴日数总体变化呈减少趋势,每10年雷暴日数减少0.7d,全年雷暴天数达21.7 d；除12月无雷暴发生外,其余11个月均有雷暴发生,4～9月雷暴日数占全年的94.4％,其中7～8月占59.6％,属于强雷季节.武当山风景区雷暴地域分布南部多于北部,雷暴表现出显著的年际和年代际变化特征,存在6年的显著年际周期,同时还存在2～4年、8～10年的振荡周期.雷暴突变最为集中的时期是在20世纪80年代初.%According to the thunderstorm data of three meteorological stations (Shiyan, Danjiangkou and Fangxian) from 1971 to 2010, this paper explored the climatic changes in Wudangshan scenic area through applying the mathematical statistics, wavelet transform and M - K analysis. The results indicated that in recent 40 years the number of thunderstorm day presented a decreasing trend, and the decreasing speed was 0.7 d per 10 years, the average number of thunderstorm day in a year was 21.7 d. The thunderstorm occurred in 11 months except December. The number of thunderstorm day from April to September accounted for 94.4% of that in the whole year, and that from July to August did 59.6% , so these two months belonged to the strong thunderstorm season. The geographical distribution of thunderstorm in the south of Wudangshan was more than that in the north. The thunderstorm in Wudangshan appeared remarkable inter - annual and inter - decade changes, and it existed obvious inter - annual period of 6 years and the oscillation periods of 2 ~4 years and 8 ~ 10 years. The most concentrated stage of thunderstorm mutations was in the early 1980s.
