摘要
利用华南地区 1 0 9个站 1 95 1～ 2 0 0 1年的寒害过程降温幅度和最低气温资料 ,分别用正态分布、指数分布、伽玛分布、瑞利分布、威布尔分布和耿贝尔 -Ⅰ分布函数进行拟合 ,并按柯尔莫哥洛夫和ω2 检验方法进行了拟合优度检验。结果表明 ,华南地区寒害过程降温幅度有 5 1个站服从正态分布、2 9个站服从伽玛分布、2 0个站服从耿贝尔 -Ⅰ分布、9个站服从威布尔分布 ;过程最低气温有 1 2个站服从正态分布、97个站服从耿贝尔
Normal distribution, Exponential distribution, Gamma distribution, Rayleigh distribution, Weibull distribution and Gumbel-Ⅰ distribution are used to fit temperature drop range and minimum temperature series for cold damage from 1951 to 2001 in 109 meteorological stations of the South China. The fitness is checked up by Kolmogorov test and ω 2 test. The results show that there are 51 stations being subject to normal distribution, 29 stations Gamma distribution, 20 stations Gumbel-Ⅰdistribution, 9 stations Weibull distribution in temperature-drop range series for cold damage, and there are 12 stations being subject to normal distribution, 97 stations Gumbel-Ⅰ distribution in minimum temperature series for cold damage.
