Abstract

This paper studies the effects of global climate change on Gyeonggi Bay and appropriate adaptation strategies. Located along the west coast of Korea, Gyeonggi Bay is renowned as one of the five most important global tidal flats (wetlands). Due to climate change in Gyeonggi Bay, the water temperature is predicted to increase by 1.44 ℃ by the year 2100, the salinity to decrease by 1.1 PSU, the sea level to rise by 35.2 cm, and approximately 150.5 km2 of the coast to be submerged due to the rising sea levels. Adaptation strategies to combat negative impacts of climate change on the ecological environment of Gyeonggi Bay include 1) supporting the self-adaptation capability of Gyeonggi Bay's natural environment to be sustainable, and 2) protecting lowlands adjacent to tidal flats and low-lying areas of the coast against human involvement to reserve more space for upslope shifts of biota with rising sea levels.

세계 5대 갯벌해역으로 유명한 한국 서해 경기만의 기후변화 영향을 파악하고, 기후변화 영향을 최소화하기 위한 적응방안 연구하였다. 경기만의 기후변화 영향으로 2100년에 수온은 1.2 ℃ 증가하고, 염분이 1.1 PSU 감소하며, 해수면은 35.2 cm 상승하는 것으로 예측되었다. 또한 해수면 상승의 효과로 150.5 km2의 해안지역이 침수될 것으로 예상되었다. 기후변화로 인한 경기만 생태환경 영향을 최소화하기 위한 적응대책으로는 1) 경기만 자체 자연환경의 적응능력 유지를 위한 지원, 2) 생물 서식지 확보를 위한 인간 활동 조정 등 두가지 방안이 제시되었다.
