摘 要 ：20世纪初，I．W．Bailey和E．W．Sinnot首先提出被子植物叶片的一些特征，尤其是全缘叶种类百分比和年平均气温之间的相关关系非常密切。70年代末，J．A. Wolfe定量研究了全缘叶种类百分比和年平均气温之间的线性关系。90年代以来，叶相分析进入多变量分析阶段，J．A．Wolfe提出“气候与叶片多变量分析程序”(Climate-keaf Analysis Multivariate Program CLAMP)。运用CLAMP程序在定量重建古气候、古纬度、古海拔等方面已取得一些重要研究进展。最后，本文对有关问题进行了讨论。
Abstract:At the begianing of the 20 th century, I．W．Bailey and E．W．Sinnot proposed a novel idea Of the close correlation Of physiognomic characteristics，particularly percentage Of entire species with mean annual temperature．In the late 1970s Jack A．Wolfe investigated the linear correlation of percentage of entire species and mean annual temperature．In 1990s Jack A．Wolfe developed Climate-Leaf Analysis Multivariate Program(CLAMP) which is characteristic of accuracy and precision peftainjng to the estimates of palaeoclimate，palaeoelevation，etc．Relevant problems are discussed and future directions are prospected．
