钱江源国家公园古田山珍稀濒危植物资源现状及分析

Status and analysis of rare and endangered plant resources in Gutianshan of Qianjiangyuan National Park, East China

  • 摘要: 在钱江源国家公园古田山国家级自然保护区珍稀濒危植物系统调查的基础上,对该地区珍稀濒危植物的种类组成、保护价值、地理区系特征及分布现状进行了系统研究。结果显示:古田山地区共有省级及以上野生珍稀濒危种子植物32科55属63种,其中被《国家重点保护野生植物名录》(第一批)收录的Ⅰ级保护植物1种、Ⅱ级保护植物15种,被《中国植物红皮书》收录的有15种,浙江省重点野生保护植物19种,其余物种分别被《中国物种红色名录》和《中国高等植物受威胁物种名录》收录;保护区内的多数珍稀濒危植物分布区狭窄,除少数保护植物如野大豆Glycine soja Siebold&Zucc.、野含笑Michelia skinneriana Dunn、杨桐Cleyera japonica Thunb.等种类的种群较大外,其他种类的种群较小;长序榆Ulmus elongata L.K.Fu&C.S.Ding、香果树Emmenopterys henryi Oliv.、榧树Torreya grandis Fortune ex Lindl.、三小叶山豆根Euchresta japonica Benth.ex Oliv.、金刚大Croomia japonica Miq.等种类零星分布于核心保护区,有少量珍稀植物如南方红豆杉Taxus wallichiana Zucc.var. mairei(Lemée&H.Lév.)L.K.Fu&Nan Li、花榈木Ormosia henryi Prain等位于缓冲区或试验区;保护区珍稀濒危植物属的区系成分较丰富,温带成分相对较多,中国特有属的濒危度较高,急需采取相应保护措施。

     

    Abstract: Based on a systematic survey of rare and endangered plants in Gutianshan National Nature Reserve, Qianjiangyuan National Park, we conducted a systematic study on the species composition, conservation value, geographic characteristics, and distribution of rare and endangered plants in the region. Results showed a total of 63 national and provincial endangered seed plant species in the Gutianshan area, belonging to 32 families and 55 genera. Among them, one Class Ⅰ and 15 Class Ⅱ species were included in the National List of Key Protected Wild Plant, along with 15 species in the China Plant Red Data Book, 19 species in Zhejiang Province's Key Protected Wild Plants, and the remaining species in the China Species Red List and Threatened Species List of China's Higher Plants. The majority of threatened species maintained only small populations and a narrow distribution range, except for a few species including Glycine soja, Michelia skinneriana, and Cleyera japonica. Threatened species such as Ulmus elongata, Emmenopterys henryi, Torreya grandis, Euchresta japonica, and Croomia japonica only sporadically spread into the core area of the reserve, whereas species such as Taxus wallichiana var. mairei and Ormosia henryi were scattered in the buffer or test zones. Floristic geographic analysis showed that a higher percentage of threatened species were temperate rather than tropical genera and the degree of endangerment for endemic genera was high. Improved measures should be established to strengthen the protection of these rare and endangered species.
