초록

본 연구는 부산시의 대표적인 도시하천인 온천천에서 가뭄 및 집중호우 등 환경적 교란이 수질 및 부착규조류 군집에 미치는 영향을 파악하기 위하여 2013년~2014년 2년간 연구를 수행하였다. 긴 갈수기였던 2013년 4분기~2014년 1분기와 2014년 3분기에 강한 집중 호우 사이에 급격한 하천 수질 변화를 보였다. 부착규조류는 비교적 짧은 유하거리에 비해 도심화 정도에 따라 상류에서 하류까지 뚜렷하게 군집 구조 변화를 보였으나 긴 가뭄기간 동안 감소된 유량은 종조성에 영향을 주어 Cocconeis placentula var. lineata에서 Gomphonema clevei이 우점종으로 바뀌고 Gomphonema 속 등 주요 분포 종으로 조사되었다. 갈수기 이후 강한 강우로 부착규조류의 종조성보다 생물량이 급격하게 감소되었고 이는 국지적 기후 변화로 수생태계 구조와 기능에 많은 영향이 생김을 알 수 있었다. 따라서, 기후 변화에 의한 도시기후의 이상현상과 도시하천의 수질 및 부착규조류의 분포 특성 연구는 도시하천 생태계 특성과 변화 연구에 있어서 기초 자료로 활용될 수 있을 것으로 기대하며 국지적인 환경변화에 대응하는 도시하천의 유지관리 방안을 찾는 데 도움이 될 것으로 판단된다.

This study illustrates changes in the epilithic diatom assemblages in response to urban climatic conditions. We further assess the impact of abnormal urban climate to the urban stream environment. Epilithic diatoms, water chemical and physical variables were sampled every quarter, and assessed at 3 Oncheon stream sites, for a period of two years(from 2013~2014). The variation of physiochemical properties such as BOD, COD, T-N and T-P, show that the water quality was strongly influenced with long periods of drought and flood disturbance. Epilithic diatom assemblages were separated along the stream sites; however, the physical disturbance from urban drought and stormwater changed the composition of diatom assemblages instead of decreasing the taxonomic richness. Thus, our results suggest that epilithic diatom assemblages are altered in response to urban climatic changes, resulting in variations of stream conditions. Hence, strategies of climate change adaptation are required when considering urban stream environments.
