轿子山国家级自然保护区重点保护植物生存状况及保护建议

采取样线和样方相结合的方法，对轿子山国家级自然保护区的保护植物资源现状展开全面调查。结果表明：轿子山共有保护植物35种，新增发现国家Ⅱ级保护植物云南梧桐、箭叶大油芒和西藏杓兰；珍稀濒危植物喜马拉雅红豆杉从原有7株增至13株；攀枝花苏铁的种群数量通过人工扩繁和野外监测进一步增加，其他保护植物的生存状况得到了不同程度的改善。基于此，提出建立健全管护机构、各管理部门有效配合、适时开展本底资源调查等保护建议。

Survival Status and Protection Suggestions of Key Protected Plants in Jiaozishan National Nature Reserve

The comprehensive investigation was conducted on the current status of protected plant resources in Jiaozishan National Nature Reserve by line and square sampling methods. The results showed that there were 35 species of protected plants in the reserve, including newly discovered the national II-level protection plant Firmiana major, Spodiopogon sagittifolius, and Cypripedium tibeticum; the rare and endangered plants Taxus wallichiana increased from the original 7 strains to 13 strains; the populations of Cycas panzhihuaensis had further increased through artificial propagation and field monitoring, and the survival status of other protected plants had been improved to varying degrees. Therefore, this paper proposed to establish and improve management and protection institutions, effectively cooperate with various management departments, and timely carry out background resource surveys.
