Analysis on the types and species diversity of Cinnamomum camphora community in urban forest remnants
摘要
Abstract
In this paper,the common Cinnanomum camphora community in the urban forest of Wuhan was selected as the research object.Based on the study of the important values of the species in the 15 quadrats of the sample plots and according to the method of group connection,the remaining camphor communities in the study area were classified.According to different community types and different structure level,the remaining camphor tree community types were divided,and we also analyzed the Patrick richness index,Shannon-Wiener diversity index,Simpson diversity index and Pielou even ness index.The results showed that the remaining camphor communities in the study area were divided into 6 association.They are Association 1:Ass.Cinnamomum camphora-Ligustrum lucidum-Dryopteris championii;Association 2:Ass.Cinnamomum camphora-Li gustrum lucidum + Trach ycarpus f ortunei-Parathel ypteris nipponica + Dryopteris fuscipes;Association 3:Ass.Cinnamonum camphora-Pittosporum tobira + rach ycarpus f ortunei-Paederia scandens;Association 4:Ass.Cinnamonum camphora-Pitlosporum tobira Trachelospermun jasminoides + Dryopteris chanpionii;Association 5:Ass.Cinnamomun camphora-Trachycarpus fortunei + Ilex chinensis-Dryopteris championii;Association 6:Ass.Cinnamomum camphora-Quercus variabilis-Pteridium aquilinum.The Patrick richness index of Association 1 was the highest.The Shannon-Wiener diversity index (H),Pielou evenness index (J) and Simpson diversity index (D) of Association 4 were the highest.The remained camphor communities in the study area were divided into three layers:tree layer,shrub layer and herb layer.In terms of the diversity index of each layer,five of them exihibted the pattern of herb layer ＞ shrub layer ＞ tree layer,while association 4 with the pattern of shrub layer ＞ herb layer ＞ tree layer.The study could provide scientific reference for the restoration of the remaining camphor forest vegetation in Wuhan.关键词
