摘　　要：文章将气象要素场转化为秩序统计量场，用ＥＯＦ迭代方案进行气象要素场的恢复研究．利用全国４２个站点１９５１～１９９５年夏季（６～８月）雨量场资料对１９０１～１９５０年夏季雨量场进行了恢复，并在此基础上用Ｂａｙｅｓ判别法对雨带类型进行了恢复．检验表明，所恢复的资料是可靠的．fter converting the meteorological element field to the rank statistic field, the meteorological element field was retrieved with EOF iteration method. By using the data of summer rainfall field of 42 observatories in China from 1951 to 1995, the summer rainfall fields from 1901 to 1950 in China were retrieved, and then the rain belt types were also retrieved with Bayes discriminate method. The test results indicate that the retrieved data are reliable.
