A Pilot Study On China’ Rural Community Common Greening Tree Species Composition And Diversity

As an important part of rural ecosystem,rural community greening tree species play an important role in biodiversity conservation and the country in maintain ecosystem function.However,rapid urbanization and industrialization,has brought serious challenges for rural greening tree species conservation and sustainable use,resulting in the loss of part of the native tree species,therefore,it is important for us do the investigation and analysis of common greening tree species composition and diversity,find out problems of the local and put forward the corresponding countermeasures and measures.In China within the scope of this study,the questionnaire survey to 299 rural communities commonly used statistics of Chinese rural community greening tree species composition,on this basis,do four villages like fanggan village and so on,such as rural village as a case for the tree species composition and diversity of the community of pure research,on the national,regional and individual country scale of rural community greening tree species composition of genera and species origin,function and so on has carried on the systematic analysis of species.The results showed that the scales in the whole country,rural community preferred common greening tree species,a total of 113 species(including varieties)belonging to 53 families,87 genera,including fruit tree is sort more,the most widely popular;at the regional scale,between different regions there are significant differences between species richness and the species composition,species richness in east China is higher;Scale in the country,the species richness and evenness by rural local vegetation,degree of human intervention,the industrial development pattern and so on a variety of factors,but less manual intervention villages preserved the relative number of native tree species;Exotic tree species in different scales has been a certain ratio,part of exotic trees application scope is bigger.Based on the results of the study,discusses our country rural community tree species of the main problems in the protection and sustainable utilization,put forward Suggestions on the application and protection of rural community greening tree species.In this paper,the results of research for our country community green space planning and design and ecological environment protection configuration of tree species,the conservation and sustainable use of reference and guidance significance.
