Abstract

In order to utilize coal ash for eelgrass beds, a pilot plant experiment was carried out. Eelgrass was transplanted to on artificial bed made of granulated coal ash. Successful settlement of eelgrass was achieved and the density of the eelgrass increased at an exponential rate through vagetative propagation after 24 months. An increase in biodiversity in and around the artificial eelgrass bed was observed after the transplant took place. From the results of this experiment, it can be concluded that granulated coal ash is a suitable material for creating eelgrass beds.

산업부산물인 석탄회을 이용하여 잘피군락의 조성 가능성을 평가하기 위한 현장실험을 실시하였다. 오염된 점토질 해저면에 석탄회 조립물을 이용하여 인공지반을 조성하고 잘피를 이식한 후 모니터링을 실시하였다. 이식된 잘피는 조성된 지반에서 성공적으로 정착하였으며, 이식 후 24개월 이후부터는 이식된 잘피의 개체길이의 증가 및 영양번식을 통한 잘피의 밀도의 빠른 증가가 확인 되었다. 또한 조성된 잘피군락 및 그 주변에서 저서생물 및 미세조류의 종수가 증가하여 자연잘피군락과 동일하게 연안역의 생물다양성 향상에 도움이 되는 것을 확인할 수 있었다. 이상의 결과로부터 석탄회 조립물은 잘피군락 조성에 적합한 재료임을 확인하였다.
