| 摘 要： | 本文应用主分量分析方法对海南省的年降水量、年降水平均值、标准差和距平百分率进行统计分析结果发现，前5个分量可表示降水总方差的83％，它已反映出年降水场最重要的特征。时间系数和特征向量的组合，将年降水场分为5种类型，并确定了海南省逐年降水量的类型，全省性旱和涝的几率最高，占58％，其次是东南旱西涝，占17％。

| Abstract: | It has been used the principal component method to analyse Hainan's annual rainfall, annual mean rainfall and their standard deviation, annual anomaly percentage statistically in this paper. Results show that the first five components can present 83% of total variance of the rainfall and indicate the most important characteristics of the annual rainfall field as well. It also has devided the annual rainfall field into five types, and dicided the types of the rainfall for each year of the said province. The results represent that the probabitlty of the drought and flood in the whole region is the highest which is accounting for 58%, and the next is the type of drought in the southeast and flood in the west which is accounting for 17%. |
