珍稀濒危植物长苞铁杉群落植物区系分析

A floristic survey was made of a Tsuga longibracteata community in Tianbaoyan National NatureReserve in Fujian Province. There are 140 species of vascular plants belonging to 49 families and 86 genera in the investigated quadrats with a total area of 3 600 m2 in the community, in which pteridophytes comprise 7 families, 7 genera and 9 species, gymnosperms 2 families, 4 genera and 4 species, and angiosperms 40 families, 75 genera and 127 species. The floristic elements at the family and genus levels are mainly pantropical with a certain proportion of temperate elements, whereas at the species level, species endemic to China and species of East Asia are the dominants with larger proportion of temperate elements and certain proportion tropical elements. The T.longibracteata community containing considerable amount of primitive taxa is considered to be endangered. The areal types of vascular plants in the community at family, genus and species levels are tabulated.
