Abstract

In this paper, it was constructed the halophyte Mesocosm experimental which was used tidal flat and dredged sediment as a substrate material. Depending on the vegetation and substrate material of Mesocosm, Mesocosm A(tidal flat sediment + Salicornia herbacea), Mesocosm B (only dredged sediment), Mesocosm C(dredged sediment + Salicornia herbacea). Monitoring was carried out of Warter quality factots(Chemical Oxygen Demand(COD), Total Nitrogen(T-N), Total Phosphorus(T-P), water temperature, salinity), Sediment factors(Chemical Oxygen Demand(COD), Total Nitrogen(T-N), Total Phosphorus(T-P)) and growth of Salricornia herbacea. 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 in Mesocosm A, it was evaluated to be able to be used in the restoration and construction of the coastal salt marsh with dredged sediment.

본 연구에서는 갯벌토 및 준설토를 기질로 이용한 Mesocosm 실험을 통하여 염생식물의 서식안정성을 평가하였다. Mesocosm 실험구는 기질 및 식생의 식재 여부에 따라 Mesocosm A(갯벌토+퉁퉁마디 식재), Mesocosm B(준설토), Mesocosm C(준설토+퉁퉁마디 식재)로 조성하였다. 그리고 Mesocosm 실험구 내 염생식물의 서식안정성을 평가하기 위해 수질(COD, T-N, T-P, 수온, 염분), 저질(COD, T-N, T-P), 식생성장률의 서식환경 인자에 대한 모니터링을 실시하여 서식안정성지수(HSI)를 산정하였다. Mesocosm C에서의 HSI는 0.87~0.95로서 Mesocosm A에 비하여 상대적으로 HSI가 높게 산정되어, 준설토를 이용한 해안염습지의 복원/조성에 이용될 수 있을 것으로 평가되었다.
