Community characteristics and species diversity of Emmenopterys henryi habitat in Yashu Mountain,Fujian Province,China
摘要
Abstract
[Objective]This study investigated the community characteristics and species diversity of Emmenopterys henryi habitat in Yashu Mountain,Fujian Province,to provide a basis for the conservation of wild E.henryi communities.[Method]Sample plot meth-od was used to obtain the E.henryi habitat information,and the importance values of dominant species,diversity index,diameter structure,height structure and community stability were determined and analysed.[Result]The E.henryi habitat community in Yashu Mountain harbored 143 plant species,which belonged to 93 genera and 64 families.The dominant families were made up by Lauraceae,Rosaceae,Fagaceae,Rubiaceae and Dryopteridaceae,with Phoebe sheareri,Mallotus philippensis,Maesa japonica and Selaginella uncinata as the dominant species,and E.henryi was an important part of the arbor layer.The plant diversity index of each layer followed the order of arbor layer(2.121)>herb layer(1.976)>shrub layer(1.437).The E.henryi population were seriously lack of middle diameter class,and featured by low stability.[Conclusion]The community stability of E.henryi habitat was low at all layers,therefore strengthened environmental monitoring and appropriate anthropogenic protection measures were highly recommended.关键词
