摘要
对浙江清凉峰国家级自然保护区43种珍稀濒危植物的组成、濒危等级现状、区系成分、利用价值进行了整理和初步分析。结果表明,浙江清凉峰43种珍稀濒危植物录属于28科38属,其中裸子植物3科6属,被子植物22科32属,其中属于属于国家重点Ⅰ级保护的有银杏(Ginkgo biloba)、南方红豆杉(Taxus chinensis var.mairei)和银缕梅(Shaniodendron subaequalum)3种,国家Ⅱ级保护的有金钱松(Pseudolarix amabilis)、华东黄杉(Pseudotsuga gaussenii)、榧树(Torreya grandis)等23种,国家Ⅲ级保护的有南方铁杉(Tsuga chinensis var.tchekiangensis)、天目木姜子(Litsea auriculata)、青檀(Pteroceltis tatarinowii)、天麻(Gastrodia elata)等17种;区系成分复杂多样,可分为10个分布区,中国特有分布、东亚─北美洲间断分布、东亚分布以及北温带分布成分是浙江清凉峰珍稀濒危植物的特征成分,具有明显的亚热带至温带性质,同时热带性分布的属也占有相当的比重;可作为药用植物、园林观赏植物、建筑及工业原料等。提出了维持适宜生境、加强就地保护和迁地保护的保护对策。
There are 43 rare and endangered plant species belonging to 28 families and 38 genera in Zhejiang Qingliangfeng National Nature Reserve （ZQNNR）. Three species are under Class I National Protection, 23 species under Class II, and 17 species under Class III according to the National Protection List and China Rare Endangered Plant Directory. Analysis on the taxonomy, endangered grade and floral elements of these plants showed that floristic composition is complex, it could be divided into 10 distribution zones.
