The structure of mangrove community and the feature of Avicennia marina population of Techeng Island, Zhanjiang was surveyed using sample-quadrat method during June 2008. The results of the investigation showed that:the mangroves in the region are A.marina pure forest, and mixed forest of four species (A.marina, Rhizophora stylosa, Bruguiera gymnorrhiza, and Aegiceras corniculatum) in which A.marina is the dominant species. A.marina distributes continuously on the beach from the landward to the seaward. R.stylosa, B.gymnorrhiza and A.comiculatum grow in the landward and the central of the beach. The species diversity index decrease from the landward edge to the seaward edge. By analyzing the trend of plant height, base diameter of A.marina population, young individuals gathered landward, very little grow seaward. The age structure of A.marina population shows that this population is in growth form. However, according to the environment and the distribution of A.marina population, the mangrove in this area will degenerate in the future.
