摘要：苏铁起源于3亿年前的晚石炭纪。仙湖苏铁（Cycas fairylakeaD．Y．Wang）属于苏铁科苏铁属，为国家I级濒危保护植物，根据IUCN的最新标准，仙湖苏铁可列为极危物种（CR）等级，其不仅具有较高的观赏性，更是名符其实的“活化石”，对研究古地理的变迁及生物的演化有重要意义，作为珍稀古老物种基因更有不可替代的价值。
To study the population characteristics of Cycas jhirylakea D. Y. Wang, a comprehensive field investiga- tion was conducted with the help of GPS system. In this study, the quantitative characteristics and age structure of the genet were analyzed, and their distribution pattern and grow conditions were evaluated. In investigation, I 013 C. fairylakea trees were found, which distributed in patch. Although the population scale and structure get better re- covery, being limited by the topography and microclimate conditions, the growth conditions and natural proliferation ability of the population is still very fragile. To make C. fairylakea get rid of endangered status, it is proposed to es- tablish a protection area for it and adopt necessary measures to promote the regeneration and development of the pop- ulation.
