수변생태벨트는 유역의 비점오염원을 저감시키고 생태적인 연결성과 건강성을 증진할 수 있는 효율적인 기법이다. 국내에서도 수변생태벨트 조성 및 관리를 위한 법적인 제도를 운영 중이나 비점오염물질 제어, 생물서식처 등 완충 기능에 유리한 하천, 호소 내의 홍수터는 제외되어 개선이 필요하다. 이에 따라 본 연구에서는 금강 수계 대청댐 유역을대상으로 댐 호소의 소단위별로 댐 홍수터와 수변구역의 수질, 생태계 특성을 종합적으로 평가하는 통합형 수변생태벨트 적지 선정방안을 제시하고 분석하였다. 먼저 GIS로 대청댐 유역을 138개 소단위로 구분하고 홍수터와 인접한수변구역을 분석하였다. 통합형 수변생태벨트 적지 선정에 영향을 미치는 생태계, 수질 영향 관련 16개의 평가인자를선정하고 AHP분석으로 인자별 중요도에 대한 가중치를 설정하였다. 소단위에 제내·외지별, 인자별 가중치를 적용한통합 평가를 실시하여 적지 우선 순위를 도출하였다. GIS 적지 분석을 통해 도출된 대상지들이 실제 조성에 적합한지역인지 타당성을 판단하기 위해 5개 대상지에 대한 토지이용, 오염원, 생태적인 연계성 등에 대한 현장 검증을 시행한 결과 모든 대상지가 적정함을 확인할 수 있었다. 본 연구를 통해 제시된 수변생태벨트 적지 분석 기법은 향후통합적인 수변관리 정책 설정시 유용한 도구로써 적용될 수 있을 것이다. 단, 대상 댐별 특성과 현안에 따라 다양한평가인자와 항목별 가중치 적용이 필요할 수 있다. 그리고 통합형 수변생태벨트 지역에 대해 그린-블루네트워크(Green-Blue Network) 측면을 고려한 세부적인 보전·복원방안 마련과 생태계서비스 측면의 평가 및 관련 법, 제도측면의 상호 연계, 개선방안 등에 대해서도 추가적인 연구가 이루어져야 할 것이다.
Abstract
The riparian eco-belt is an efficient technique that can reduce non-point pollution sources in the basin and improve ecological connectivity and health. In Korea, a legal system for the construction and management of riparian eco-belts is in operation. However, it is currently excluded that rivers and floodplains in dam reservoir that are advantageous for buffer functions such as control of non-point pollutants and ecological habitats. Accordingly, this study presented and analyzed a plan to select a site for an integrated riparian ecol-belt that comprehensively evaluates the water quality and ecosystem characteristics of each dam floodplain and riparian zone for the Daecheong Dam basin in Geum River watershed. First, the Daecheong Dam basin was divided into 138 sub-basin with GIS, and the riparian zone adjacent to the dam floodplain was analyzed. Sixteen evaluation factors related to the ecosystem and water quality impact that affect the selection of integrated riparian eco-belt were decided, and weights for the importance of each factor were set through AHP analysis. The priority of site suitability was derived by conducting an integrated evaluation by applying weights to sub-basin by floodplains and riparian zone factors. In order to determine whether the sites derived through GIS site analysis are sutiable for actual implementation, five sites were inspected according to three factors: land use, pollution sources, and ecological connectivity. As a result, it was confirmed that all sites were appropriate to apply integrated riparian ecol-belt. It is judged that the riparian eco-belt site analysis technique proposed through this study can be applied as a useful tool when establishing an integrated riparian zone management policy in the future. However, it might be necessary to experiment various evaluation factors and weights for each item according to the characteristics and issues of each dam. Additional research need to be conducted on elaborated conservation and restoration strategies considering the Green-Blue Network aspect, evaluation of ecosystem services, and interconnection between related laws and policy and its improvements.
