Structural characteristics analysis of Sinojackia oblongicarpa community
Taking the wild community of Sinojackia oblongicarpa as the research object,and using the method of sample survey to investigate and analyze the species composition,community structure,and plant distribution area types of the tree layer,shrub layer,and herbaceous layer in the community.The results indicate that there were 56 species of plants belonging to 51 genera and 37 families in thecommunity.There were 6 families,6 genera,and 6 species of trees,27 species of 24 genera of shrub,and 19 families,21 genera,and 23 species of herbaceous plant in the community.Based on the perspective of importance values,the important values of Machilus pauhoi,Sinojackia oblongicarpa,Liquidambar formosana in the tree layer,Derris fordii,Clematis chinensis,Clerodendrum bungei in the shrub layer,and Corydalis decambers,Lycoris radiata,Chrysanthemum indicum in the herbaceous layer were higher valume in the community,respectively.Based on the perspective of plant distribution types,the seed plants in the community were mainly distributed in the world wide and subtropical(tropical wide)genera.The population size and distribution range of S.oblongicarpa were small,making natural regeneration difficult.It was recommended to strengthen the protection efforts of S.oblongicarpa.
