초록

전라북도 전주시의 전주천에서 2000년 4월부터 2002년 12월까지 상류인 한벽교부터 삼천 합류지점까지 도심을 관통하는 7.2km의 구간에서 "자연형하천 조성사업" 이루어졌으며, 이에 대한 전주천의 자연형 하천 조성 사업 전과 후의 어류상 및 군집을 조사하였다. 조사 결과 조성사업 이전인 1975년부터 1999년까지 전주천에서는 12종~8종의 어류가 출현하였으나, 공사 이후인 2003년~2008년 사이에는 총 34종이 확인되어 어류의 다양성이 크게 향상되었다. 특히 도심지인 중류지점 (다가교-서신교사이)에서는 공사이전에는 5종의 적은 종이 출현하였으나 공사 이후에는 22종으로 급증하는 특징을 보였다. 이러한 어류상의 변화는 자연형 하천 공사로 인해 생활하수의 유입 차단으로 인한 전주천의 수질개선 및 직강화 되고, 평탄화 되어 있던 하천에서 여울과 소가 반복적으로 나타났으며, 또한 하상구조도 돌과 자갈, 모래, 진흙 등으로 다양화되어 어류의 서식공간이 다양화되었기 때문으로 생각된다.

This is the study of the effects and changes on the ichthyofauna and fish community in Jeonju-cheon stream (located in Jeonju Cit, Jeollabuk-do, South Korea) after the implementation of the Natural Stream Restoration Project. The restoration of the stream was carried out between April 2000 and December 2002, and it covered the mid-section of the stream starting from the upstream of Hanbyeok Bridge down to Samcheon where branches of water join. It is 7.2 km long and passes through the downtown area. In this study, comparisons were made before and after the restoration. Before the restoration (1975 to 1999), the number of fish species collected from the Jeonju-cheon stream turned out to be 12 to 18 species, whereas after the restoration (2003 to 2008), it increased up to 34 species in total. Especially in the case of the middle and downstream sections running across the central regions of the city (Daga Bridge to Seosin Bridge), the number of fish species significantly increased from 5 species to 22 species. Such a dramatic increase of fish species appears to be directly related to the restoration of the stream which was designed to improve the quality of water by preventing polluted sewage water from running into the stream. Besides, the structure of stream bed which became more diversified into various components such as marshes and shallows, as well as rocks, Pebbles, sand and clay, also contributed to the increase of fish species.
