Ordination and GLM/GAM are both important methods to explore the relationship between plant species and environment.Generally, ordination methods, based on linear model, are suitable for dealing with the vegetation within a comparatively short environmental gradient,while those based on unimodal model are more suitable for tackling with the vegetation distributing along a longer gradient.PCA, CA/RA series and CCA series are the most commonly used ordination methods.Involving the environmental data in the analysis, CCA series could demonstrate the relationship between plant species and environment clearly.After modification, DCCA and PCCA are considered to be ideal ordination methods at present.Essentially, General Linear Model (GLM) and General Additive Modal (GAM)were using the high power po
