| 摘要: |
| 为摸清陈禾洞保护区兰科植物资源, 通过典型生境路线法进行调查, 分析资源分布现状与受威
胁因素, 提出相应的保护策略。 结果表明: 陈禾洞兰科植物共有 3 属 65 种, 种属的成分较为复杂多样;
从区系来看, 陈禾洞兰科植物分为 8 类型和 1 变型, 以热带分布属为主, 具有较高的热带属性; 有国家二
级重点保护野生植物 13 种, 被 《IUCN 濒危物种红色名录》 收录 8 种; 生活型齐全, 以地生兰为主, 广
布种占优势, 海拔对物种分布存在一定影响。 保护区应加强兰科资源动态监测, 综合采取就地保护、 迁地
保护和回归等技术措施, 从而进行有效保护。 |

| Abstract: |
| We investigated the orchid resource in the Chenhedong Provincial Nature Reserve by the way of
typical habitat path. After assessing and comparing the endangered situation, we analyzed the resource status and
threatened factors, and proposed the protection strategies. The results showed that there were 65 species of 37
genera in the reserve. The composition of the species is relatively complex and diverse. The geographical composition were divided into 8 types and 1 variants, with dominant distributed in tropical zone. 13 species are secondary state national protection. Eight were listed by IUCN Red List of Endangered Species. All of three life forms
were found, terrestrial are dominant, the high species are dominant. Chenhedong Provincial Nature Reserve
should strengthen the dynamic monitoring, take comprehensive technical measures such as in situ protection, ex
situ protection and regression study, to effectively protect the orchid plant resources in the reserve. |
