This study investigated the natural environment of the tidal flat island in Shinangun, Jeonnam. The main topic involved was geomorphology, geology and landscape. In general, the natural environment of tidal flats is only evaluated upon ‘State’ in PSR (Pressure-State-Response) frameworks.
The tidal flats in the Bigeum-Docho-Anjwa airea have a high value of conserving ecosystem, natural landscape, sediment, seawater quality, geomorphology and geology. The Haeui-myeon area includes Okdo in the center of Palgupo sea, which is called the Diamond Islands. The tidal flats have a large number of marine products, such as fishing without gear, which contributes largely to the income of local fishing households.
The tidal flats of Aphaemyeon and Jeungdo-Byeongpungdo have been considerably damaged due to reclamation, filling-up, etc, along with a poor natural environment caused by particulate matter, waste fishing gear and domestic waste. By enabling the selection of those tidal flats in Shinangun, tidal flats are expected to establish a system for conserving and managing tidal flats.
