Community Structure and Species Diversity of the Krummholz in Mulinzi Nature Reserve
摘要
Abstract
In order to strengthen the protection of krummholz in Mulinzi Nature Reserve,its community structure and species diversity were analyzed by means of sample site survey.The results showed that there were 53 species of woody plants belonging 19 families 31 genera.Quercus glauca was dominant species,and Fagaceae and Ericaceae were dominant family in the community.Shannon-Wiener diversity index,Simpson dominance index and Pielou evenness index were 1.411,0.559 and 0.522,respectively,indicating that the diversity of the community was low,and most plants were eliminated by the environment during succession.The community flora had an ancient origin,was deeply influenced by tropical flora with temperate character,showing obvious transition characteristics from subtropical to temperate zone.The diameter class structure of the community showed an inverted"J"type distribution,and the natural regeneration was good.The dominant species Q.glauca had a similar diameter class structure to the community,and occupied a dominant position in the succession process.Therefore,it would provide a theoretical basis for the protection,scientific management and later construction of the moss dwarf forest on the top of the mountain.关键词
