Investigation of Wild Resources and Community Structure of Tinospora sagittata in Leigong Mountain Nature Reserve
摘要
Abstract
The minimum area method was used to investigate the typical Tinospora sagittata community in the typical Tinospora sagittata distri-bution area in Leigong Mountain Nature Reserve.The results showed that the wild Tinospora sagittata mainly distributed in the forest margin,hillside foot,stone crevices on both sides of the stream or dark damp places in the gully zone,and also in the forest and the soil edge of the field,but the number was small.The vegetation types were mostly coniferous broad-leaved mixed forest,evergreen deciduous mixed broad-leaved forest.The soil is yellow soil with more sand and gravel content.The altitude is 700-1 400 m and the population density is low,ranging from 0.014 to 0.027 plants/m2.There are few wild resources of Tinospora sagittata in the area,which is endangered.In addition,the Tinospor asagittata community consists of 59 families,89 genera and 95 species of vascular plants,and the dominant family and genus are obvious.The composition of family and genus is complex,and the species are mainly concentrated in the family with 1 species and the genus with 1 species.The number of species increased with the increase of the sample volume.The number of species in 100 square meters increased significantly,and then gradually leveled off.When the sample volume was 512 m2,the number of species in the community was 95.关键词
