Abstract: According to taxonomic system of Raunkiaer, the flora compositions of three Fagus longipetiolata communities along elevations gradient were investigated, and their life form spectra were analyzed in Junzifeng Natural Reserve, Fujian Province. The results showed that there were local climates characteristic of hot and rainy but with a long term hard winter season. And phanerophyte were dominant in the communities, hemicryptophyte secondly,燾hamaephytes and cryptophytes were less or none and without therophyte.

摘要： 采用Raunkiaer生活型分类系统，调查福建君子峰自然保护区不同海拔长柄水青冈Fagus longipetiolata群落的植物种类组成，并分析其生活型谱。结果表明，长柄水青冈群落植物组成以高位芽植物占优势，其次为地面芽植物，地上芽和地下芽植物比例较少或没有，没有一年生植物。反映了该群落所在地的气候炎热多雨，但有一较长的严冬季节。
