Field survey was made on the community characteristics of wild Reevesia xuefengensis in Gaowangjie National Nature Reserve of Hunan Province in terms of habitat, quantitative characteristics of dominant population, vertical structure and population dynamics. The results showed that Reevesia xuefengensis and Cyclobalanopsis glauca were the dominant population in the community, which gave the name to the community as community of Reevesia xuefengensis and the Cyclobalanopsis glauca. The vertical structure of the community was obvious, which can be divided into three layers of arbor layer, shrub layer and herb layer, with less plant between the layers. The age-grade structure of Reevesia xuefengensis population was of bell type with decline tread; while that of Cyclobalanopsis glauca population was increasing. Cyclobalanopsis glauca will eventually replace Reevesia xuefengensis and forms a stable top-level community. The measures of planning protection scope, implementing dynamic protection management and strengthening artificial rejuvenation are put forward.

Key words: Reevesia xuefengensis, community characteristics, Gaowangjie, national nature reserve
