A Comparison Study of Trace Elements along Two Transects in Tidal Mangrove Marsh at Dongzhaigang, Hainan, China

Abstract:

The mangrove marshes are important for coastal ecosystem and play an important and irreplaceable role in the maintenance of coastal biodiversity. A mangrove transect and a bald beach transect with similar topography were selected for comparison study in Dongzhaigang National Nature Reserve, Hainan. The observation wells were installed and then the pore water sample was collected. The constant elements and trace elements of the pore water were analyzed. Based on the results, the trace elements of the two transects were discussed. It was found that the concentration of antimony and lead of mangrove marsh are higher than that of bald marsh, which most probably due to the contamination of anthropogenic activity. The method of decreasing the concentration of trace elements in mangrove marsh is proposed.
