漳河源自然保护区国家重点保护野生植物及保护对策

漳河源自然保护区位于南漳县西南部。在野外调查和文献资料查阅的基础上,对该区国家重点保护野生植物的分布情况进行了研究,结果表明:该区共有国家保护植物21种,其中I级保护植物3种,它们是银杏、红豆杉、南方红豆杉;II级保护植物18种,它们是篦子三尖杉、大果青扦、金荞麦、连香树、野大豆、红豆树、鹅掌楸、厚朴、凹叶厚朴、香果树、榉树、喜树、樟树、闽楠、桢楠、红椿、巴山榧树和黄皮树.分别占湖北省分布的45.65%,37.50%和47.37%。该区的这些国家保护植物具有分布集中、居群规模小、片段化严重、垂直分布明显的特点.并提出了相应的保护对策。

Resource and protection of the national key preserved wild plants in Zhangheyuan Nature Preserve

Zhangheyuan Nature Preserve is located in the southwest of Nanzhang county, Hubei province. Based on the field investigation and known data, the distribution of national key preserved wild plants in this area was studied. The results showed that there were 21 species of national key preserved wild plants,among which 3 species belonged to the first class(including Ginkgo biloba,Taxus chinensis and Taxus chinensis var. mairei)and 18 species belonged to the second class(Cephalotaxus oliveri,Picea neoveitchii,Fagopyrum dibotrys,Cercidiphyllum japonicum,Glycine soja,Ormosia hosiei,Liriodendron chinense,Magnolia officinalis,Magnolia officinalis ssp.biloba,Emmenopterys henryi,Zelkova schneideriana,Canvptotheca acuminate,Cinnamomum camphora,Phoebe bournei,Phoebe zhennan,Toona ciliate,Torreya fargesii and Phellodendron chinense). Each accounts for 45.65%, 37.50% and 47.37% of the species distribution in Hubei province, respectively. The characteristics of the national protected plants in Zhangheyuan Nature Preserve were concentrative distribution, small population, severe fragmentization and distinct elevation distribution. Some effective conversation suggestions also had been put forward in this study.
