Abstract:The community characteristics are analysed on the basis of the floristic composition,physiognomy and structure, as well as the population characteristics of Amentotaxus argotaema on Qingcheng mountain. The survival curve and the age structure of Amentotaxus argotaenia population suggest that the population is an increasing type of the nature community.The population has obvious shade-adapted and rock-growed properties. Maybe it is an adaptive selection of the relic population in the natural evolution. Between the studied community and the subtropical evergreen broad-leaved forest there is no distinction in tropical floristic component, temperate component, life form spectrum, leaf size class spectrum and leaf texture spectrum, but the endemism, ancient and relic nature exist obviously in the studied community. It seems that the Amentotaxus argotaenia community is a special community type of subtropical evergreen broad-leaved forest.
