초록

본 연구에서는 확률밀도함수의 서식처 적합도 지수를 사용하여 도심하천구간과 자연하천구간에서 유량점증방법론(Instream flow Incremental Methodology, IFIM)을 토대로 피라미 서식처의 생태유량을 모의하였다. 이와 같은 방법을 적용하기 위하여 본 연구에서는 PHABSIM 모형을 사용하였다. 본 연구에서는 서식처 적합도 지수(Kang, 2010)를 기초로 확률밀도함수의 매개변수를 조정하여 확률밀도함수의 서식처 적합도 지수를 개발하여 생태유량을 분석하였다. 그 결과, 도심하천구간에서는 정규분포가 자연하천구간에서는 2변수 log-pearson 분포가 Kang (2010)의 생태유량에 가장 근접하는 경향을 보였다. 확률밀도함수에 의한 서식처 적합도 지수와 하천구간별로 생태유량을 모의하여 확률론적 방법을 적용한 생태유량 산정기법을 제안하였다.

In this study, the ecological flow rate of the Zacco playtypus habitat was simulated based on the Instream Flow Incremental Methodology (IFIM) in reachs of urban and natural stream using the habitat suitability index (HSI) of the probability density function (PDF). To apply this method, PHABSIM model was used in this study. However, in this study, the HSI of the probability density function was developed by adjusting the parameters of the PDF based on Kang (2010) HSI. As a result, the normal distribution is closest to the ecological flow rate of the Kang (2010) in the urban stream. However, the two-parameter log-pearson distribution tended to be the closest in the natural stream. The ecological flow rate was simulated by the HSI and the reach of stream with the PDF. Based on the comparison of simulation results, we propose an ecological flow rate estimation method using probabilistic method.
