摘　　要：元宝山冷杉是仅分布于广西融水县元宝山上的濒危树种。本文分析认为致使其濒危的主要原因是气候变迁，此外，种子发芽率低、群落环境以及人为活动影响也是导致其濒危的重要原因。建议在严格保护和管理现有生境的同时，开展人工辅助更新，并在生境相似的地方育苗造林。Abies yuanbaoshanensis is an endangered tree species which distributes only in Yuanbaoshan Mountain, Rongshui County, Guangxi Zhuang Autonomous Region. It has been found that the endangerment of Abies yuanbaoshanensis is mainly caused by climate changes. In addition, the ecological environment of the community, the human activities and the low seed germination percentage are also important causes to the endangerment of the species. It has been suggested the while taking strict measures for the conservation and management of the existing habitats, artificial supplementary regeneration should be lunched and reforestation of Abies yuanbaoshanensis trees should be implemented in appropriate habitats.
