Abstract

Abstract:

Quantitative classification and ordination aiming to realize multifactor ecological land classification was developed for the mountainous region in eastern Liaoning Province. Data for ground flora and canopy trees species from selected stands were summarized and subjected to TWINSPAN classification and PCA, CCA ordination. CCA indicated that slope and aspect were highly correlated with the ground flora and canopy tree species. Pairwise MRPP tests indicated many significant differences (P<0.05) among the vegetation groups and environmental factors. 6 types of plant community, which can be used to indicate the vegetation type in ecological classification system, were based on cluster analysis of the six most environment factors. The vegetation of the mountainous region in eastern Liaoning Province was believed to be related a moisture and nutrient gradient which was mainly influenced by slope and aspect, which can be used as criterion in ecological land classification.

Key words: quantitative classification and ordination, ecological land classification, environmental factors, mountainous region in eastern Liaoning Province
