摘　　要：采用样线法对广东省70个自然保护地的桫椤科植物资源进行了野外调查,结合历史资料对其分布与种群数量进行了比较分析。结果表明:70个自然保护地和若干非自然保护地中有32个自然保护地和3个非自然保护地共出现桫椤科植物5种,种类占广东省全部9种的55.56%。其中32个自然保护地中有桫椤1040株;6个自然保护地有大叶黑桫椤428株;3个自然保护地有粗齿桫椤270株;15个自然保护地有黑桫椤676株;14个自然保护地有小黑桫椤400株。提出了对其中的3种国家重点保护植物(桫椤、大叶黑桫椤和黑桫椤),尤其是非自然保护地中的种群需加强监管、宣传和科研力度,以保证其种群的生存和发展。The transect method was used to investigate the resources of Cyatheaceae in 70 nature reserves in Guangdong,and their distribution and population were compared and analyzed based on historical data.The results showed that among the 70 protected areas and some non-protected areas,32 protected areas and 3 non-protected areas had 5 species of Cyatheaceae,accounting for 55.56% of all the 9 species in Guangdong.Among them,there are 1040 individuals of Alsophila spinulosa in 32 nature reserves;There are 428 individuals of A.gigantea in 6 nature reserves;There are 270 individuals of Gymnosphaera denticulata in 3 nature reserves;There are 676 individuals of G.podophylla in 15 nature reserves;There are 400 individuals of G.metteniana in 14 nature reserves.Among them,three national key protected plants(Alsophila spinulosa,A.gigantea and Gymnosphaera podophylla),especially the populations in non-nature reserves need to strengthen supervision,publicity and scientific research to ensure the survival and development of their populations.
