摘要
应用D.M.Hershflcld的几何分布分析了用旬降水量表示干旱历时概率分布的可行性,分区研究了黄淮海平原干旱历时的概率特征;应用Sen的方法分析了黄淮海平原季节性干旱的年际历时的概率分布,为减灾抗灾提供理论依据。
The paper analysed the feasibility of using precipitation calculated in ten-day perieds to showdrought duration and gave the probability features of drought duration in 5 areas of HHH plain usingD. M. Hershfield’s geometrie distribution. It also dealt with probability distribution of seasonaldrought duration among years in the furmentioned regions applying Sen’s method.
