　　The objective of this study was to determine whether there was significant seasonal and zonal variation in the species composition of algae in both intertidal mangrove (Avicennia marina and Sonneratia apetala) communities,seasonal and zonal variation in the macroalgal biomass in the Sonneratia apetala community,as well as the macroalgal bioaccumualtion to elements in Avicennia marina community along the shore in the vicinity of the Donghai embankment of Zhanjiang city,south of China.During the four seasons,31species were totally identified in 15 genera,of which 9 species belonged to 4 genera of Cyanophyta,5 species belonged to 3 genera of Rhodophyta,16 species belonged to 7genera of Chlorophyta,and 1 species belonged to 1 genus of Phaeophyta respectively in the two mangrove communities.The algal species were the most abundant in Spring,followed by in Summer,Winter and Autumn in turn in both mangrove communities.
