경북지역 중소 하천에 설치된 수중보 현황 및 생태 환경 조사

This study was conducted to investigate the weir constructed in river basin, Gyeong-Buk Province Statue and evaluate the ecological environment deponding on the result of water quality analysis of upper stream, lower stream and richness, diversity, evenness. Study period was from June, 2008 to September, 2008 for two times. Study sites were selected as Nam stream(Kumho river water system) joined into the confluence of Kumho river in Suseong district meaho, Dae-Gu Metropolitan City and Nakwhaam stream(Neaseong stream water system) joined into the confluence of Neaseong stream in Bonghwa gun, Gyeong-Buk Province. Temp., pH, DO, EC, Turb., SS, BOD were conducted for analysis of water quality. The flora was investigated, as a result of that, the naturalized ratio was calculated. The richness, diversity, evenness were calculated by investigating fish Community. As a result of the evaluation of ecological environment, overall it is better lower stream than upper stream. But the study was conducted for a short period, it need to set up ecological environment by continuous monitoring and improving the problem.
