【摘要】 开展国家珍稀濒危保护植物的考察、研究,对探讨区域生物多样性的性质、评价生态环境的状况和质量,提出适当的自然保护、管理对策等,均具有重要的指导意义。本文调查研究了井冈山地区珍稀濒危植物的种类、数量、分布、生长状况以及重要木本植物的群落特征,探讨了珍稀濒危植物的系统学与生物地理学特征。结果表明,井冈山地区有濒危苔藓植物2种,各类珍稀濒危野生维管植物199种。其中被《世界自然保护联盟濒危物种红色名录》收录50种,被《中国物种红色名录》收录160种,被《国家重点保护野生植物名录(第一批)》收录49种,被《濒危野生动植物种国际贸易公约附录》收录90种。本区珍稀濒危植物的种类和数量大体上与峨眉山相当,而远高于武夷山和太白山,在系统学与生物地理学上有重要意义,具有极高的保护价值。本区保存有较大面积的以珍稀濒危植物为优势种的群落,如资源冷杉(Abies beshanzuensis var.ziyuanensis)、华榛(Corylus chinensis)、白豆杉(Pseudotaxus chienii)、南方红豆杉(Taxus wallichiana var.mairei)、福建柏(Fokienia hodginsii)、穗花杉(Amentotaxus argotaenia)、闽楠(Phoebe bournei)、马醉木(Pieris japonica)、井冈山杜鹃(Rhododendron jinggangshanicum)等群落。更多还原

【Abstract】 The occurrence of rare,endangered,and protected plant species is of importance in assessing the status of local biodiversity and the environment as well as developing strategies for nature conservation and management.The abundance and distribution of rare and endangered plants in the Mount Jinggangshan region were investigated as well as the community characteristics of important woody species.The results demonstrate that rare and endangered species have high conservation value and significant importance in systematics and biogeography.This area contains two endangered bryophyte species and 199 species of vascular plants.Among them,50 species are included in the IUCN Red List of Threatened species,160 species in the China Species Red List,49 species in the List of Wild Plants Under State Protection(First Batch),and 90 species in the Appendices of CITES.The variety and abundance of rare and endangered species in this area are equivalent to those for Mount Emei and higher than those for Mount Wuyi and Mount Taibai.Many perfectly preserved communities,covering a large area,exist in the Mount Jinggangshan vicinity,and are dominated by rare and endangered species,such as Abies beshanzuensis var.ziyuanensis,Corylus chinensis,Pseudotaxus chienii,Taxus wallichiana var.mairei,Fokienia hodginsii,Amentotaxus argotaenia,Phoebe bournei,Pieris japonica,Rhododendron jinggangshanicum,etc.The communities where some important rare and endangered plants occur are described in detail and suggestions are made for their protection.更多还原
