Abstract

Monimopetalum chinense is a plant belonging to a monotypic and endemic genus of Celastraceae in China.It is listed as one of the Chinese national grade-2 protective rare and endangered species.Based on the information of 11 quadrats,the species diversity of communities with endangered plant Monimopetalum chinense was analyzed by means of richness index,species diversity index and evenness index.The results showed that species diversity of communities with Monimopetalum chinense was high with complex structure of plant community and abundant species.On the average,the species richness index and species diversity index were in the order of shrub layer > herb layer > tree layer,while the species evenness index was sequenced as herb layer >shrub layer> tree layer.The species diversity in the tree layer was poor,the number of plant species was low,and the dominant plant species were prominent.The survival of Monimopetalum chinense was affected seriously by human activities,such as deforestation and unreasonable development of tourism.

Key words： Monimopetalum chinense community species diversity richness evenness
