Abstract

We need to analyze the ecological characteristics in the basin of agricultural reservoir that include urbanized area, agricultural area and fringe area, etc. The purpose of this study is not only that presenting the methods of basin ecosystem management but also suggesting ecosystem management plan proposals for the water quality based on analysis of ecological characteristics. As the results of analysis, the urbanized area(the ratio of area(ROA): 14.0%) is most likely to possibility of water pollution, then followed by paddy fields(ROA: 65.5%) where a wide spread up-basin(or up-stream), farmlands(ROA: 11.3%), farm buildings(ROA: 5.7%) and orchard(ROA: 3.9%). According to those, we investigated the impact degree of water pollutants. Thus, we were able to classify 5 types through considering the biotope assessment and the hydrosphere basin assessment, i.e. the level of priority control for source pollution. As a result, the source pollution intensive management area(11.3%) where are adjacent waterfront has caused water pollution, however, most importantly, it is necessary to control in source pollution management area(0.6%) that are away from waterfront. In conclusion, according to the these results, the plan of basin ecosystem management for the water quality should be included the plan of ecosystem conservation and restoration such as improving inhabitants function, controling environmentally sound basin management, promoting biodiversity.

본 연구는 농업용 저수지의 유역권(약 1,500ha) 중 직접 영향을 미칠 수 있는 도시화지역, 농경지 등, 대상지 일대의 생태적 특성을 분석한 후, 이를 바탕으로 생물다양성의 선결과제인 수질관리를 위한 유역권 생태계 관리방안을 제안하였다. 대상지 유역생태계 토지이용현황 분석결과 시가화지역(14.0%)에 의한 수질오염 가능성이 가장 높았고 유형별 분포는 상류에 대면적으로 분포하는 논(65.0%), 밭(11.3%), 시설경작지(5.7%), 과수원(3.9%) 등의 순이었다. 관리를 위해 수질에 영향을 미치는 정도를 평가한 비오톱 유형평가와 오염원 관리 우선정도를 평가한 수계권역 평가를 고려하여 5개 유형으로 구분한 결과, 수변에 인접한 오염원집중관리지역(11.3%)과 오염물질을 유발하고 있으나 수변에서 떨어져 있는 오염원관리지역(0.6%)에 대한 관심이 필요하였다. 관리는 저수지 생물서식 기능 향상 및 유역권 관리를 통한 환경친화적 호소관리를 통한 생물다양성 증진, 생태계 보전 및 복원방안을 제안하였다.
