Analysis of the Functional Diversity of Woody Plants on the Campus of Xuchang University
In order to improve the green landscape of the university campus,24 sample areas were set up on the campus of Xuchang University to investigate the functional diversity of woody plants.The results showed that there were 104 species of woody plants in 80 genera and 60 families,and the flowering period was concentrated in spring and summer.The average values of the five functional diversity indexes(functional richness index,functional evenness index,functional differentiation index,functional dispersion index and functional quadratic entropy index)were 9.38,0.62,0.66,2.75 and 9.4,respectively.The five functional diversity indices of the dining area,building A,building B teaching area,library area and office area C were higher than the average value,but these five functional diversity indexes on the garden roads were all low.The five functional diversity indexes were positively correlated with the four species diversity indexes.In the future,it is necessary to improve the functional diversity of the campus in the areas with low plant functional diversity,especially the garden road,and enrich the garden landscape of the campus.
