Abstract

The objective of this study was to evaluate biodiversity and natural habitat environment of freshwater ecosystem. Our aim was therefore to produce a set of biodiversity and habitat indicators based on multi-parameters of water quality and biodiversity by analyzing the characteristics of the results by indicators. We selected four indicators a) anthropogenic disturbance, b) habitat diversity, c) biodiversity, d) ecosystem structure. The fishes cohabiting with Brachymystax lenok tsinlingensis were Rhynchocypris kumgangensis and Zacco koreanus. As a result of the anthropogenic disturbance evaluation, it was analyzed that vegetation embankment showed a more stable environment in the tributary than the main stream, and other disturbance was not confirmed As a result of the habitat diversity evaluation, it was analyzed that habitat evaluation index showed a high score of 200 more on average, showing an optimal habitat condition. As a result of the biodiversity evaluation, it was analyzed as a clean habitat condition with a high proportion of sensitive species, abundant dissolved oxygen, and little pollutants. As a results of the ecosystem structure, the ecological health condition metrics and appearance of endangered species showed large score deviation, but it was analyzed that the stream ecosystem health was generally excellent. There was a slight correlation between the habitat environment and the results of the nature habitat evaluation according to the appearance of the B. lenok tsinlingensis.

본 연구는 수생태계 생물다양성과 자연 서식지 환경을 유역 수준에서 평가하기 위해 수질과 수생태 분야를 중심으로 통합 지표를 개발하였으며, 지표별 결과 특성을 분석하여 적용성을 검토하였다. 자연성 평가체계는 인간 활동에 의한 교란, 서식지 다양성, 생물다양성, 생태계 구조의 4가지 평가분야와 7개 세부 평가지표로 구성하였다. 하천 생태계의 서식지 보전을 위해 평가 대상 생물군으로 어류를 활용하였으며, 멸종위기야생생물 II급 열목어와 최대 서식지인 계방천과 내린천을 평가대상으로 선정하였다. 조사 수역은 대부분 하천차수가 낮은 산간계류 형태로 열목어의 공서어종은 금강모치와 참갈겨니로 분석되었다. 자연성 평가 결과, 교란 현황 분야에서 본류보다 지류에서 제방 식생이 안정적인 환경을 보였으며, 외부 교란이 적은 것으로 분석되었다. 서식지 다양성 분야에서는 서식지 평가 지수가 평균 200 이상의 높은 점수를 나타내어 최적의 생물서식 환경을 보이는 것으로 분석되었다. 생물다양성 분야에서는 민감종의 비율이 높고, 용존산소가 많은 편이며 오염물질이 거의 없는 청정상태로 분석되었다. 생태계 구조 분야에서는 생태지표특성 메트릭과 멸종위기야생생물의 출현에 따른 점수 편차가 큰 특성을 보였으나, 대체로 하천생태계 건강성이 우수한 것으로 분석되었다. 열목어의 출현 유무에 따라 서식지 환경에 차이를 보이면서 자연성 평가 결과에 다소 차이를 보이는 것으로 나타났다. 생태계 변화 관찰 목적에 따라 자연환경 변화를 신속하게 탐지하고 하천생태계 보전을 위한 평가체계로 활용하기 위해서는 다양한 유역을 대상으로 조사 분석이 이루어져야 할 것으로 판단된다.
