Abstract:

A preliminary study of Vatica guangxiensis community inMt. Maocaoshan of Xishuangbanna is carried out by
means of the phytocoenological method. Vatica guangxiensis ( Dipterocarpaceae) and Altingia andersonii ( Hamamelidaceae)
are dominant tree species of the upper layer in the community, which can be divided into A, B, C, D, E layers.
and is mainly charactered by evergreen megaphaenerophytes and mesophaenerophytes with simple, chartaceous, entire,
caudal mesophyll leaves. There are a lot of wooden lianas and epiphytes between layers. Being the northern extension of
the tropical seasonal rain forest of Laos, the community is rich in species, stable dynamic structure, limited distribution,
fragil ecosystem as well as urgent need for prior protection.
