Abstract

In order to establish fundamental data for stream restoration and environmental flow, we investigated optimal ecological flowrate (OEF) and riverine health condition in the Chogang Stream, a tributary to Geum River, Korea. The number of fish individuals sampled in this period were 4,669 in 36 species of 9 families. The most abundant species was Korean chub (Zacco koreanus, 34.0%) followed by pale chub (Z. platypus, 22.6%) and Korean shinner (Coreoleuciscus splendidus, 13.3%). Index of biological integrity (IBI) and qualitative habitat evaluation index (QHEI) values decreased from upstream to downstream along the stream. The estimated IBI value ranged from 27.9 to 38.6 with average 32.2 out of 50, rendering the site ecologically fair to good health conditions. OEF was estimated by the physical habitat simulation system (PHABSIM) using the habitat suitability indexes (HSI) of three fish species Z. koreanus, C. splendidus and Pseudopungtungia nigra selected as indicator species. In Z. koreanus, HSI for flow velocity and water depth were estimated at 0.1 to 0.4 m/s and 0.2 to 0.4 m, respectively. In P. nigra, HSI for flow velocity, water depth and substrate size were estimated at 0.2 to 0.5 m/s and 0.4 to 0.6 m and fine gravel to cobbles, respectively. OEF values ​​increasing from up to downstream was found to increase, weighted usable area (WUA) values ​​increased accordingly.

하천복원과 환경유량을 위한 기초자료를 확립하고자 금강수계의 초강천에서 생물학적 건강성 및 최적 생태유량에 대하여 조사하였다. 출현한 어종은 총 9과 36종 4,669개체였으며, 잉어과가 66.7%(24종)로 가장 높았다. 참갈겨니가 1,588개체로 34.0%로 우점종이었으며, 아우점종은 피라미로 22.6%, 우세종은 쉬리 13.3%로 나타났다. IBI와 QHEI는 상류로부터 하류로 내려갈수록 값이 감소하는 것으로 나타났으며, IBI 값은 27.9∼38.6으로 평균 32.2로 양호상태를 나타냈다. 참갈겨니, 쉬리 및 감돌고기에 대하여 서식도적합도지수(HSI) 및 최적 생태유량을 산정하였다. 참갈겨니의 경우, 유속과 수심의 HSI 값은 각각 0.1∼0.4 m/s와 0.2∼0.4 m 였다. 감돌고기는 유속이 0.2∼0.5 m/s, 수심이 0.4∼0.6 m 및 하상재료가 가는자갈∼호박돌로 나타났다. 이를 기초로 하여 각 지점의 최적 생태유량은 하류로 내려갈수록 값이 증가하는 것으로 나타났으며, 이에 따라서 WUA 값도 증가하는 것으로 나타났다.
