Q-model faetor analysis on twenty thousand grains of sPores and Pollen andalgae from more than a hundred samPles of ten eolumn sections in the East ChinaSea has been made.Based on the faetor loadings matrix and the faetor seoresmatrix obtained,the palynologieal assemblages from the sediments of the EastChina Sea sinee Late Pleistoeene ean be divided into eight sPores and Pollen zones.Zonesl-3 are dated as the Latest Pleistoeene and zones4一8 as Holoeene.ThisPaPer also deseribes the Proeedure of Q-model faetor analysis in detail  相似文献

因子分析作为一种多元统计分析方法,其目的就是要从一定数量的变量中,找出数目较少的彼此独立的基本变量,称为因子,并且用它来表示原来的那些变量.从而通过这些因子来研究和分析变量的系统分类和成因分类.它在六十年代后期才开始在孢粉研究中应用,Williams等(1967)最早应用R型因子分析,对委内瑞拉的奥里诺河三角洲沉积中的孢粉、藻类进行研究,而得出四种不同沉积环境的孢粉组合[1].  相似文献
