Abstract: Mangrove ecosystem is a very special ecosystem lying in the intertidal zone. With the rapid pace of urbanization in coastal area in recent years, the increasing household garbage, industrial waste water and other pollutants are directly poured into the sea soars. Heavy metal elements are one of the most serious pollutants which resulted in the pollution of coastal area. Lots of reported studies illustrated that mangrove ecosystems which lie in the intertidal zone have the capability of assimilating and accumulating heavy metal elements. This article summarizes the regular pattern of mobilzing, accumulation and purification of heavy metal elements in mangrove ecosystems, based on the features of mangrove ecosystems. Moreover, the study suggested some anti-pollution methods and provides scientific basis for the protection and the ecological benefit evaluation of mangrove ecosystems.
