雷公山玉山竹群落特征和物种多样性研究
Characteristics and Species Diversity of Yushania leigongshanensis Communities
摘要
Abstract
This study adopted a sample plot survey method to analyze the species composition,important value characteristics,and species di-versity of Yushania leigongshanensis communities.The results show that:There are a total of 35 families,48 genera,and 65 species in the two Yushania leigongshanensis communities.In the α diversity indexes,except for the Margalef index in sample plot 1,which shows herbaceous layer>tree layer=shrub layer,all other indices show herbaceous layer>tree layer>shrub layer.The α diversity index shows that sample plot 1 is smaller than sample plot 2 in the tree and herb layers.In the shrub layer,except for the Margalef index,which shows that sample 1 is smaller than sample plot 2,all other indices show that sample plot 2 is smaller than sample plot 1.The Cody index and Whittaker index of the shrub layer are significantly lower than those of the tree and herb layers,while the Jaccard index and Sorenson index of the shrub layer are signifi-cantly higher than those of the tree and herb layers.The co-dominant species in the tree layer of sample plot 2 show a trend of succession to-wards the single dominant species in the tree layer of sample plot 1.关键词
