The relationship between nutritional status, sediment bacteria and mangrove plant growth was examined to lay a foundation of the coastal green belt recovery and expansion. The elevation of topography above the mud flat probably prevented the inner area from salt-washing by tidal water, resulted in the extremely high salinity of the sediment. The plant growth in the dry section, therefore, was low. Sediment humidity and salinity strongly affected the nutritional status through their effects on the distribution and activity of Vibrios and Enterobacters, who can take parts in the nitrogen and phosphorus cycling. The strong growth of Avicennia lanata at the mud flat probably resulted from the abundance of sediment bacteria.
