摘要
在查找史料的基础上,根据国家重点保护植物名录(第一批),确定了在广东有分布的仙湖苏铁、银杏、南方红豆杉、合柱金莲木、伯乐树、报春苣苔、水松、异形玉叶金花和台湾苏铁9种国家I级重点保护植物作为调查对象,在全省开展了较为全面的调查。结果只找到了前6种,植株数量合计为123468株。除仙湖苏铁和报春苣苔分布地点没有变化外,其他7种的分布地点丧失率在20%-100%之间。除南方红豆杉基本上属于正常种群外,其余8种分属于野外绝迹、濒临绝迹或濒危类物种,其资源状况堪忧。在对其资源现状进行详细分析的基础上,提出了相应的保护管理策略和发展措施。
Based on the list of wild plant species of national importance issued in 1999 （first part） and the recorded data, there are 9 taxa of national protection grade I distributed in Guangdong Province, viz. Cacys taiwaniana, Cycas fairylakea, Ginkgo biloba, Glyptostrobus pensilis, Mussaenda anomala, Primulina tabacum, Sinia rhodoleuca Taxus wallichiana var. mairei and Bretschneidera sinensis. A survey of the 9 taxa was made during 1998 to 2001, with complementary investigation afterwards. According to IUCN red list 2001 categories and criteria, Cacys taiwaniana, Glyptostrobus pensilis and Mussaenda anomala are extinct in the wild （EW）. Ginkgo biloba is critically endangered （CR）. Bretschneidera sinensis, Sinia rhodoleuca, Primulina tabacum and Cycas fairylakea are endangered （EN）. Taxus wallichiana vat. mairei is nearly threatened （NT）. Conservation strategies of the 9 taxa are suggested.
