摘要 应用福鼎市1977-2007年的气象观测资料,寻找并拟合了极值分布。经检验证明,福鼎市年极端最低气温服从Fisher—Tipper第一型极值分布(Gumbel分布)。依据极值分布可计算福鼎市某年内可能出现的极端最低气温,这为按树引种栽培防止发生冻害提供了参考依据。 The limited value distribution and its changeable trend of atmospheric temperature in Fuding city during 1977 - 2007 were explored and discussed. It was proved that the distribution of the annual lowest atmospheric temperature was submitted to type I of Fisher - Tippett's distribution of limited value ( Gumbel distribution). By applying the theory of K - C, the annual probable lowest air temperature in certain years was computed, which could provide references for the prevention of frost damage in the introduction and cultivation of eucalyptus.
