TAILIEUCHUNG - Mesocosm Assessment of Stability Habitat for Halophyte

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 to 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. | Journal of Geoscience and Environment Protection 2015 3 11-19 Published Online August 2015 in SciRes. http journal gep http Scientific Research Publishing Mesocosm Assessment of Stability Habitat for Halophyte Sunghoon Ryu Incheol Lee Department of Ocean Engineering Pukyong National University Busan South Korea Email firesinger@ Received 10 June 2015 accepted 19 August 2015 published 25 August 2015 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.

Keywords Salt Marsh Dredged Sediment Mesocosm Halophyte Habitat Stability Index HSI 1. Introduction Coastal salt marsh has a value that is related to its flood and coastal defense function and ecosystem and conservation importance as well as its role in pollution control waste disposal and the maintenance of water quality fisheries agriculture recreation and tourism. It is the most common and extensive intertidal habitat along many temperate coastlines 1 . However some coastal marshes were lost through land reclamation and recreation. Coastal marshes in South .
