摘　　要：珍稀濒危植物是生物多样性和生态系统的重要组成部分,对维护生态系统平衡具有重要意义。在实地调查的基础上,结合2007年科考调查资料,对广东粤北华南虎省级自然保护区珍稀濒危野生植物资源的种类组成、区系特征、生活型和生境特征及其价值进行系统研究。结果表明:该保护区有珍稀濒危野生植物66科117属154种,其中国家I级重点保护野生植物1种,II级26种;《广东省重点保护野生植物名录》收录6种;《广东高等植物红色名录》收录132种;其余被《中国高等植物受威胁物种名录》和《濒危野生动植物种国际贸易公约》收录。除金毛狗[Cibotium barometz(L.)J.Sm.]、金荞麦[Fagopyrum dibotrys(D.Don)Hara]等种群较大、分布区较广外,其他种群较小、分布区较为狭隘。短萼黄连(Coptis chinensis var.brevisepala W.T.Wang&P.G.Xiao)、山豆根(Euchresta japonica Hook.f.ex Regel)等个体呈散生状分布于核心区。红椿(Toona ciliata M.Roem.)、野大豆(Glycine soja Siebold&Zucc.)等分布于保护区缓冲区和实验区。区系以热带-亚热带为主,科属R/T分别为1.33和1.48。生活型以草本植物占优势,濒危成分突出,兼具多种功能价值,亟需加以保护。Rare and endangered plants were integral components of biodiversity and ecosystems,and they played a significant role in maintaining ecological balance.Based on field surveys and in conjunction with the scientific research data from 2007,a systematic study was conducted on the species composition,regional characteristics,life forms,and habitat features of rare and endangered wild plant resources in the South China Tiger Provincial Nature Reserve in the northern part of Guangdong.A total of 154 rare and endangered wild plant species belonging to 66 families and 117 genera were observed,including 1 species of national first-class protected wild plants and 26 second-class protected species.6 species were included in the "Guangdong Province Key Protected Wild Plant List". 132 species wereincluded in the "Province Red List of Higher Plants in Guangdong". The rest were recorded by the "ChinaThreatened Species List of Higher Plants" and the "Convention on International Trade in EndangeredSpecies of Wild Fauna and Flora". Apart from species with large populations and wide distribution areassuch as Cibotium barometz (L.) J. Sm. and Fagopyrum dibotrys (D. Don) Hara, other species hadsmaller populations and more limited distribution areas. Individuals of Coptis chinensis var. brevisepalaW.T.Wang et & P.G.Xiao and Euchresta japonica Hook. f. ex Regel were sporadically distributed in thecore area. Toona ciliata M. Roem. and Glycine soja Siebold & Zucc. were distributed in the buffer zoneand experimental area of the reserve. The regional flora was predominantly tropical-subtropical, with afamily/genus R/T ratio of 1.33 and 1.48 respectively. The life forms were dominated by herbaceousplants, with a prominent endangered component, and they possessed multiple functional values, necessitatingurgent protection.
