%X On the Basis of the systematic analysis of soil fertility structure, the integrated fertility index(IFI)that reflects the fertility of paddy soil is proposed by using the fuzzy subordinate function and the principal component analysis theories and methods in this paper. In accordance with the values of IFI, the fertility levels of 43 species (genus)of paddy soil in Linchuan County, Jiangxi Province, are analysed and evaluated, the fertility grades of paddy soil are determincd, and the fertility index of each paddy soil of different fertility grades is examined.
