대규모 연안개발사업에 따른 매립으로 연안역의 갯벌 또는 염습지 등의 연안생태환경공간은 해마다 감소하고 있다. 이에 따라 연안역 Mitigation의 일환으로 인공 갯벌 및 염습지 개발의 필요성이 대두되고 있지만, 조성시 설계인자의 정량적 평가에 관한 연구는 미흡한 실정이다. 따라서 본 연구에서는 연안생태환경 공간 조성지의 복원정도 평가에 대한 기초적인 연구로서, 준설토 배합비에 따라 구분되는 현장시험구를 조성하고, 이를 대상으로 생화학적 설계인자로서 시험구 내 대형저서동물 군집의 생물다양성 및 생물량 / 식생(갈대)의 정착률 / 종속영양세균수 / 이화학적 특성(COD, IL, TN, TP, pH) 모니터링을 수행하였다. 이 결과를 바탕으로 각 인자들의 복원정도를 나타내는 복원지수를 제안하고 이를 산정하여 연안생태환경공간 조성에 따른 생화학적 설계인자를 정량적으로 평가하였다. The ecological environmental zones in coastal area, like tidal flat and salt marsh, were gradually decreased due to large scale of coastal development projects, reclamation and so on. Therefore, the development of artificial tidal flat and salt marsh has been emphasized in coastal area as mitigation concept. But studies on the quantitative evaluation of design factor were insufficient. In this paper, as a fundamental study for evaluation of restoration on the creation of ecological environmental zones in coastal area, it was conducted that the monitoring and experiment for biochemical factors (bio-diversity, population and biomass of macro-benthos, survival ratio of reed, the number of heterotrophic bacteria and physico-chemical characteristics such as COD, IL, TN, TP and pH) using a in-situ pilot plant of tidal flat and salt marsh, which was distinguished by content of dredged soil, in Jinudo, Nakdong river estuary. From results of this study, the restoration index(RI), for evaluation of bio-chemical factor on the creation of ecological environmental zones in coastal area, was suggested and quantitative evaluation was performed using a restoration index(RI).

In this study, as a basic study for prediction of topographical change in Nakdong River Estuary, monitoring of topographical changes at a sand bar around Jinudo which located in western of Nakdong River Estuary were carried out. From the results of the monitoring of topographical change, all parts except northern part of Jinudo have active topographical changes and have a tendency to deposit annually. From the results of correlation analysis between the seasonal changes of erosion/deposition rate around Jinudo and SS concentration, southern part of the Jinudo has a positive correlation. It was considered that SS worked as important factor in topographical change of southern part of Jinudo.
