Study On Living Status And Resources Distribution Of Endemic Plants Of Guiyang

Nowadays,research on Germplasm Resource of Plant is a hot topic. The development of industrialization accelerates the rate of species extinction,which made some species died out before there being no acquaintance with.One species can not be renewable when it die away, and at the same time,have effects on 10～30 species related with it. Developed counties have done many highly effective works on protecting the diversity of Germplasm Resource.Our countries have done some work on Germplasm Resource's research and collection.But in contrast with the colorful Germplasm Resource of plant in our country,it is not enough.Compared with the advanced countries,there is still a certain gap.Endemic species came into being in special environment by natural evolution and selection in tens of thousands even hundreds of thousands years.The amount of endemic species is an important sign of an area's biological diversity.It is very significant to study and protect endemic plant and Germplasm Resource on the developing tactic of biological resources.Domestic research on endemic plant is mostly limited to the facets of species resources and geographical distribution.However,systemic study on resource and living status of one area's endemic plants is rare. So is endemic plant of Guiyang.Therefore,the study focuses on the species,geographical distribution,resource amount and community species diversity of Guiyang endemic plant,and the main results showed as follows:1.According to records,there are 11 species in Guiyang,which belong to 10 families and 10 genus.As a result,5 species(Deutzia esquirolii, Camellia kweichowensis,Ilex qianlingshanensis,Tilia fulvosa,Keteeria davidiana var.chienpeii) were found in the investigation,and the others(Tylop hora anthopotamica,Rosa.kweichonensis,Diospyros esquirolii,Deutzia pilosa,Hanceola labordei,Symplocos martinii) were not found.2.The life types of Guiyang Endemic Plant fall into 3 types,in which arbor and shrub includes 5 species,respectively.Only 1 species belongs to herbs. 3.Based on investigation and statistical analysis,resource distribution of Keteleeria davidiana var.chien-peii and Camellia kweichowensis are more concentrative than Ilex qianlingshanensis, Deutzia esquirolii and Tilia fulvosa.The amount of resources were quite less.4.Analysis on Guiyang endemic plant's community species diversity shows that native communities' species diversity is higher than secondary Communities'.This is mainly attributed to the destroying and influence of their living habitation.Endemic plants of Guiyang were first to be completely studied at the taxonomic level of species.All results make us profoundly know composition,nature and character of the angiosperms flora of Guiyang. The living status and resources distribution of endemic plants of Guiyang were profitably explored,which added new content to study of Guiyang plants.
