Abstract
The Syzygium hancei seasonal rain forest is one of the zonal vegetation types along the coast of Guangxi. According to a investigation conducted in 2009,it was scarce now and only reserved as geomantic forests (about 19. 1 hm2) beside villages in Fangchenggang city, meanwhile,some individuals occasionally appeared in other coastal areas. According to the investigations in the plots of 1200m2,97 plant species belonging to 40 families and 75 genera were recorded in the communities of S. Hancei. The structure of the tree layer was simple and could usually be distinguished into 2 layers or just 1 layer. The S. Hancei was dominant species in all communities investigated. For all these communities were impacted seriously by human and livestock activity,the diversity index was low. Seedlings and saplings were not found in the un-derstory and the mature trees were the main constitution,so the population of S. Hancei was at a decreasing stage. The individuals in low height class and small DBH class of these communities were dominant,but the S. Hancei was mainly in the last two classes. So,with the development of succession,it would gradually decline from the communities,replaced by other dominant species.关键词
