Abstract

Lagoon, attributed to the postglacial sea-level rise, has experienced rapid geomorphological changes due to increasing human impact. This study tried to infer how rapidly increasing human impact during the Holocene affects on geomorphological changes of lagoons and their surroundings, especially on Cheongchoho, Gyeongpoho and Pungho with significant changes in area and shapes. It was confirmed that the period of rapid artificial change commonly began in the 1960s to 1970s and geomorphological landscape rapidly changed since human impact intensified afterward. Intensive development not only affected on depth, area and shape changes, but also had significant impacts on water environment and biodiversity, attributed to disturbed flow between freshwater and seawater due to dredging and the installation of artificial structures. Lastly, various types of human impact were observed to be complexly interrelated, which seems to be associated with the geomorphologic process influenced by both terrestrial and marine environments. It is thought to be the result of complex interactions between humans who develop and utilize the terrain and changes in environmental conditions.

후빙기 해수면 상승 이후 형성된 지형인 석호는 최근 인간 간섭의 증가로 인해 급격한 지형 변화가 발생하고 있다. 본 연구는 국내 석호 중 면적과 형태가 비교적 크게 변화한 청초호, 경포호, 풍호를 대상으로, 홀로세 동안에 석호와 그 일대에서 급격히 증가한 인간 간섭이 지형 변화에 미친 영향을 추론하였다. 그 결과, 인위적 변화가 급격하게 발생한 시기는 세 지역에서 공통적으로 1960~1970년대부터 시작된 것으로 확인되었고, 이후 인간 간섭이 본격화되며 지형 경관이 빠르게 변화된 것으로 나타났다. 또한 집약적 개발은 수심, 면적, 형태 변화뿐만 아니라, 수환경, 생물 다양성 측면에도 큰 영향을 미친 것으로 나타났는데, 이는 준설 및 인공구조물 설치로 담수와 해수 사이 흐름이 교란된 결과로 보인다. 마지막으로 여러 인간 간섭 유형이 복합적으로 관찰되었는데 이는 육지와 해양 환경의 영향을 모두 받는 지형 형성 과정과 관련되어 있을 것으로 보이며, 환경 조건 변화에 더하여 지형을 개발하고 이용하려는 인간 사이의 복잡한 상호작용에 의한 결과인 것으로 판단된다.
