Abstract:

Using the phytosociological method, a preliminary study was made on the Pometia tomentosa forest community. The community is one of the representative types of the tropical sea-sonal rain forest in Xishuangbanna. 25 plots was made in the forest and a synthetic table of the community was got from the study. In the table, the character and function of each plant in the community can be reflected through its abundance-coverage, presence and coefficient of coverage.The horizontal distribution of the species in the community and the classification units under the community can also be obtained from the study.

Key words: Xishuangbanna, Tropical seasonal rain forest, Pometia tomentosa community, Phytosociological method
