| 摘 要： | 采用基于 Ｅ Ｏ Ｆ Ｓ的主分量回归（ Ｐ Ｃ Ｒ）、 Ｅ Ｏ Ｆ Ｓ迭代法（ Ｉ Ｅ Ｏ Ｆ）和基于主分量典型相关的典型变量回归（ Ｃ Ｖ Ｒ）３ 种不同的统计插补计算方案，对同一区域同一种气象要素序列进行缺测资料的插补试验。结果表明，各种方案插补精度都与参数选择有关，无论缺测站点空间分布类型如何，当缺测点数小于 ６０ ％ 时，３ 种方案均有较好效果，以 Ｃ Ｖ Ｒ 最佳，且随缺测年数增长， Ｃ Ｖ Ｒ 优势更显著。

| Abstract: | Three different statistical interpolation schemes respectively based on the principal component regression (PCR) of empirical orthogonal function (EOF),the iteration of EOF (I EOF) and the canonical variable regression (CVR) of principal component are adopted to interpolate the same missing data fields.Contrast experiments show that the interpolation precision of all kinds of schemes is associated with its parameters.If the pencentage of missing data station numbers is less than 60%,no matter what distributions these stations show,all schemes,especially CVR exhibit a satisfactory accuracy,and this character becomes more significant when data missing goes a longer time. |
