摘要
为了提升大学校园绿化景观,在许昌学院校园设置了24个样区进行木本植物功能多样性调查.结果表明:校园共有木本植物60科80属104种,花期集在春季和夏季,功能丰富度指数、功能均匀度指数、功能分异度指数、功能离散度指数和功能二次熵指数的平均值分别为9.38、0.62、0.66、2.75和9.4,餐厅区、A楼、B楼教学区、图书馆区和C办公区的这5个功能多样性指数高于其平均值,园路的5个功能多样性指数均较低.5个功能多样性指数与4个物种多样性指数显著正相关.今后应提高校园植物功能多样性较低区域尤其是园路的功能多样性,丰富校园的园林景观.
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.
