Abstract

This study explained the historical changes in the habitat structures based on the aerial photographs (1948, 1967, 1973, 1989 and 2010) of the mid-stream reach of the Mangyeong River. The habitat structure was divided into landforms and aquatic habitats. The landform was classified into bare land, vegetated land, water surface, farmland and artificial land. The aquatic habitat was classified into natural riffle, artificial riffle, run, head wando, tail wando, mid wando, pond and chute channel. The ratio of bareland decreased, and water surface and vegetated land increased after the excavation in 1970s and since the construction of weir in 1980s. As historical changes of aquatic habitat, ratio of run decreased sharply while mid wando increased sharply. aquatic habitats such as head wando, tail wando, and pond located on bars decreased dramatically.

본 연구는 보가 다수 분포하고 있는 만경강을 대상으로 항공사진(1948, 1967, 1973, 1989, 2010)을 이용하여 서식처 유형을 분류하고, 시간에 따른 서식처 구조 변화를 설명하였다. 서식처 구조는 지형과 하도서식처 중 물이 있는 서식처로 구분되었으며, 지형은 나지, 식생부, 수면부, 경작지, 교란지로 분류하였으며, 하도서식처는 자연여울, 인공여울, 평여울, 머리완도, 꼬리완도, 중앙완도, 못, 첩수로로 구분하여 면적을 산출하여 백분율로 비교하였다. 1970년대 골재채취와 1980년대 보 설치로 인하여 나지는 소멸되고 수면부와 식생부는 급격히 증가함에 따라, 평여울은 급격하게 감소한 반면, 흐름이 다소 정체되어 습지와 유사한 중앙완도 서식처의 비율은 급격하게 증가하였다. 또한, 나지와 식생부 위에 존재하는 머리완도, 꼬리완도, 못과 같은 서식처는 보 설치 이후 사라지거나 일부만 남아있다. 본 연구는 생태적인 하천관리를 위한 기초자료로서 향후 교란에 따른 하천 환경의 잠재력을 파악하는데 기초자료로 이용할 수 있을 것으로 판단된다.
