Structure Characteristics of Plant Communities and Species Diversity in Dashimengou Forest Park
摘要
Abstract
The community structure and species diversity in Dashimengou Forest Park were analyzed by using the method of typical sample area,the species diversity index,evenness index and ecological dominance index. The results are as follows:1) The trees and herbaceous species are rich,but shrub species are few,there are 28 kinds of trees in the survey area and 26 species of shrubs and 91 species of herbs, they belong to 58 families 107 genera. 2)The community structure in horizontal distribution is not obvious,but the vertical structure presents a certain regularity,they can be divided into tree layer,herb layer and shrub layer. The tree layer and herb layer structure are relatively complex, shrub layer structure is simple. 3 ) Each community tree layer is of obvious advantages,community Ⅰ, community Ⅱ, community Ⅲ consist of 3 ~4 dominant species, community Ⅳ tree layer is only one dominant species, we can not change it in a short time without human intervention. 4 ) The community species diversity index between the difference was not significant,but each community diversity index of the shrub layer is far less than tree layer and herb layer,herb layer>tree layer>shrub layer. Species richness and species diversity and distribution uniformity were positively correlated. Overall,species diversity index of the overall trend is community Ⅱ> community Ⅲ> community Ⅰ> community Ⅳ.关键词
