Application of multivariate analysis on studying relationship between plant morphological structure and ecological environment

Abstract

Abstract: In this paper, multivariate analysis is used to study the morphological and anatomical features of Quercus suber under different environmental conditions. 33 plant samples are taken, and 17 indices are selected. The results show that two-way indicator species analysis(TWINSPAN) can better cluster the samples under similar ecological environments, and detrended correspondence analysis (DCA) and principal components analysis(PCA) can give satisfied results. The cluster and ordination analyses of plant morphological and anatomical features can also be used to study the continuity and discontinuity of variations of individual features, and be useful to plant classification.

Key words: Quercus suber, Morphological and anatomical features, Gradient analysis, Quantitative classification, Ecological environment, forest fire, Prometheus model., Farsite model, fire behavior
