현재 국내에서는 전국내륙습지 일반조사 및 습지보전기본계획 등의 장기적인 계획을 통해 습지 정책이 추진되고 있다. 그러나 대부분의 정책은 습지의 면적, 분포 및 생물다양성 등 현황 파악에 초점을 두고 있으며, 습지 생태계를 하나의 유기체로 보존 및 관리하는 것에 대한 인식이 부족한 상황이다. 따라서 본 연구에서는 홍수터, 생물다양성, 서식지 제공, 관광자원 등의 기능적인 측면을 고려하여 생태축 연결이 가능한 하천습지 후보지 선정을 위한 방법론을 제시하였다. 이를 토대로 본 연구에서는 낙동강 수계에 있는 우포늪, 화포천습지, 주남저수지 3개의 습지와 생태축 연결이 가능한 후보지를 선정하고자 하였다. 본 연구에서는 낙동강 수계의 15개 표준유역 내에 존재하는 63개의 습지와 7개의 후보지를 대상으로 적지 분석을 수행하였고, 산정된 점수를 이용하여 생태축 연결에 가장 적합한 하천습지 후보지를 선정하였다. 후보지 평가를 위해 9개의 평가요소를 선정하고, 해당 평가요소들에 분위수를 이용한 점수화 기법을 적용하여 분석을 실시하였다. 결과적으로, 우포늪2(호포)가 36점으로 가장 높은 점수를 받아 생태축 연결 가능성이 가장 높은 후보지로 선정되었다. 따라서 우포늪2(호포)가 홍수터, 서식지, 생물다양성 증진 및 관광자원으로서 역할이 가능한 동시에 생태축 연결에 가장 적합한 것으로 판단하였다.

In Korea, wetland policies are currently being pursued through long-term plans such as nationwide wetland surveys and wetland conservation basic plans. However, most policies focus on understanding the status of wetlands, such as their area, distribution, and biodiversity, and there is a lack of awareness regarding the need to conserve and manage wetland ecosystems as a single organism. Therefore, this study aims to identify potential riverine wetland sites that can be ecologically connected by considering functional aspects such as floodplain, biodiversity, habitat provision, and tourism resources. This study attempted to select a candidate site that could potentially provide ecological connectivity with three wetlands in the Nakdonggang River water system : Upo Wetland, Hwapocheon Wetland, and Junam Reservoir. 63 wetlands and 7 candidate sites located in 15 subwatersheds of the Nakdonggang River were analyzed, and the most suitable candidate site for ecological connectivity was selected based on the calculated scores. A suitability analysis was conducted using 9 evaluation factors to evaluate candidate sites, and the scoring method, using quantile, was applied to these factors. As a result, Upo2(Hopo) was selected as the most suitable site for ecological connectivity, receiving the highest score 36. Therefore, it is believed that Upo2(Hopo) can serve as a floodplain, habitat, biodiversity enhancer, and tourism resource while being the most suitable for ecological connectivity.
