Abstract: According to the data of field plot, this paper deals with preliminary characteristics of shrub communities in Coloane, Macau. The results show that: There are various plants in the communities, and its family and genus are of scattered compositions. The communities are dominated with Syzygium kwangtungense, Litsea rotundifolia var. oblongifolia, Eurya nitida and Rhodomytus tomentosa, but the equality character is low. Due to lack of trees and population competition, species that are rare or with high relative abundance constitute only a small proportion. The physiognomy of the shrub is mainly decided by the phanerophytes with microphylls, mesophylls, herbaceous, deciduous and evergreen leathery, simple and unentire leaves.

Key words: shrub communities, species composition, physiognomy, Coloane
