Abstract: The Carrierea calycina forest is confined to Jinfo Shah (28˚58″N; I07˚27″E), Sichuan province. Field observations were made in this mountainal area in 1978. In this paper the composition and structure of the interesting community, its enviroment, as well as the dynamics are discussed. The Carrierea calycina forest contains 113 species of higher plants. Among the higher plants 72 species (64.2%) are endemic to China, 20 species have a Sino-Japanese distributional pattern, and a few are Sino-Southeast Asia, elements (table 1). According to the coefficient of similarity of the components, sameness in the bedrock underlying the forest, and dominant species, the forest occuring in four quadrats can be consider- ed the Corrierea calycina community. Based on Raunkiaers classification of life form, the phanerophytes rank first in the type of Carrierea calycina community amounting to 51.8% (fig. 1). Analysis of the population structures of Carrierea calycina and Lithocarpus cleistocarpus indicate that the Carrierea calycina community is not in a steady-state condition. The species Lithocarpus cleistocarpus would replace the Corrierea calycina in the community.
