ABSTRACT: In this paper, we constructed the halophyte
Mesocosm experimental group which was used as a substrate material that consisted
of tidal flat and dredged sediment. Depending on whether the ingredients of
vegetation and substrate material of Mesocosm, we constructed Mesocosm A (tidal
flat sediment + Salicornia herbecea), Mesocosm B (only dredged sediment),
Mesocosm C (dredged sediment + Salicornia herbecea). Monitoring was carried out
of seawater quality factors (Chemical Oxygen Demand (COD), Total Nitrogen
(T-N), Total Phosphorus (T-P), temperature, salinity), sediment factors (Chemical
Oxygen Demand (COD), Total (T-N), Total Phosphorus (T-P) and growth of
Salricornia herbecea) in each Mesocosm. Habitat Stability Index of vegetation
was calculating by using the monitoring results. HSI of Mesocosm C was
calculated from 0.87 to 0.95 as compared to the relatively high HSI Mesocosm A,
it was evaluated to be able to be used in the restoration of the coastal salt
marsh with dredged sediment.
