摘要:

藤枣 (Eleutharrhena macrocarpa) 是我国I级重点保护野生植物与极小种群物种。通过查阅相关文献与标本记录、访问调查和实地调查相结合的方法,重点对藤枣的地理分布、群落及种群状况等现状进行研究。结果显示: (1) 中国藤枣自1910年首次采到标本以来,至今共统计到19个分布点; (2) 藤枣间断分布于云南南部、东南部、西南部及广西那坡等热带雨林地区。由于其生境破坏严重,原记录中有9个分布点消失,现存比较可靠分布点仅10个; (3) 藤枣数量极少,目前调查可靠数量仅约40株,且未见幼苗,表明天然更新困难。基于调查结果,讨论其濒危原因,为对其进行有效保护提供理论依据。

Abstract:

 Eleutharrhena macrocarpa is a grade protected wild plant,also known as one of the tiny population. Through consulting relevant literature and records, access specimen investigation and field survey, A survey on geographical distribution、community and population status of it was conducted. The results show that: (1) there are a counter of 19 distribution points of Emacrocarpa, since 1910, the first time it was found in China; (2) E. macrocarpa is discontinuously distributed in the tropical rainforest regions of the south, southeast and southwest of Yunnan and Napo in Guangxi. Due to its habitat were severely damaged, 9 of the original record distribution points were disappeared, the number of existing distribution points which was reliable reduce to 10; (3) According to the reliable survey, the number of it just is about 40 strains, and we did not see its seedlings. it show that its natural regeneration is difficulty. Based on the results of the survey, discuss its endangered reasons, and provides the theoretical basis to protect them effectively.
