The dynamics of land-use transitions decrease the coastal resilience of the social-ecological landscape (SEL), particularly in light of the fact that it is necessary to analyze the causal relationship between the two systems because operations of the social system and the ecological system are correlated. The purpose of this study is to analyze the dynamics of the coastal SEL and create a sustainable land-use planning (SLUP) strategy to enhance coastal resilience. The selected study site was Shindu-ri, South Korea, where land-use transitions are increasing and coastal resilience is therefore decreasing. Systems thinking was used to analyze the study, which was performed in four steps. First, the issues affecting the coastal area in Shindu-ri were defined as coastal landscape management, the agricultural structure, and the tourism industry structure. Second, the main variables for each issue were defined, and causal relationships between the main variables were created. Third, a holistic causal loop diagram was built based on both dynamic thinking and causal thinking. Fourth, five land-uses, including those of the coastal forest, the coastal grassland, the coastal dune, the agricultural area, and developed sites, were selected as leverage points for developing SLUP strategies to increase coastal resilience. The results show that “decrease in the size of the coastal forest”, “decrease in the size of the coastal dune”, and “increase in the size of the coastal grasslands” were considered parts of a land-use plan to enhance the resilience of the Shindu-ri SEL. This study developed integrated coastal land-use planning strategies that may provide effective solutions for complex and dynamic issues in the coastal SEL. Additionally, the results may be utilized as basic data to build and implement coastal land-use planning strategies.

This paper presents an integrated approach to mitigation wetland site selection using functional landscape connectivity and landscape structure. This approach enables landscape designers to evaluate the relative priorities of mitigation wetland areas based on functional landscape connectivity and wildlife mobility, as well as landscape structure, composition, and configuration. The least-cost path method is used to evaluate candidate sites for mitigation wetlands with regard to wildlife movement. A set of assessments for landscape indices using FRAGSTATS was applied to identify suitable mitigation wetland areas on the basis of landscape connectivity, composition, and configuration. The study was conducted in Gwacheon, Korea, where there are plans for regional development that will change the landscape. In the first step, a group of 14 candidate sites is identified via analysis of functional landscape connectivity using the least-cost path method. In the second step, candidate mitigation wetland areas are ranked according to landscape connectivity and composition. The five mitigation wetland areas that were found to be suitable were analyzed based on landscape configuration at the class level. This study demonstrates that functional landscape connectivity and landscape structure are important aspects to consider when identifying suitable sites for mitigation wetland planning and restoration.

수조류는 몸의 크기 및 목의 길이, 부리 형태 및 다리 길이 등의 특성에 따라 수계 내에서 각각 다른 수심의 공간 을 취수지 및 휴식지로 이용함으로써 경쟁을 최소화하며 고유의 생태적 지위(Niche)를 차지한다(White and James, 1978). 따라서 수조류들의 행위는 습지생태계 및 수변부의 수위 변동에 따라 휴식 및 먹이 활동에 영향을 받게 된다 (Isola et al., 2000). 큰고니는 목을 수면 아래로 최대한 뻗는 취수 방법을 취할 경우 최대 100cm 수심까지 이용할 수 있 지만(Choi et al., 2010), 그만큼 경계에 취약해지고 에너지 손실이 크기 때문에 50cm이하의 얕은 수심을 더 선호하는 습성을 보인다(Chisholm and Spray, 2002; Choi et al., 2010). 한편 Figure 3과 같이 낙동강하굿둑의 담수방류량의 불규칙한 변동과 해수 유입의 차단은(http://www.kwater.or.kr) 을숙도 내 담수변화에도 영향을 주는 것으로 나타났으며 (Song et al., 2014), 큰고니의 휴식환경에 불균형을 초래하 여(Kim, 2011; 2013) 큰고니 월동확률에도 영향을 줄 것으 로 사료된다.
