The ordination axes clustering based on detrended canonical correspondence analysis ordination and its application to the analysis of the ecological gradients of plant communities
Abstract:Based on Detrended Canonical Correspondence Analysis(DCCA),a new classification method,DCCA Ordination Axes Clustering(OAC)was introduced and was applied to the classification of the plant communities in Bashuigou catchment,Guandi Mountain,Shanxi Province.Five types of communities can be identified with the method.It is concluded that there are obvious differences of community structure and environmental factors among the community types by using the Analysis of Variance and Multiple Comparison.So,the O...
