Abstract

It is very important to predict the environmental changes in the land-surface as a way of prevention of sustainable nature. This study investigated the difference between the predicted and actual data of Anmyeon-do from 1981 to 2000 through a fuzzy logic operation using multi-spectral image. According to literature survey, maps, and ground truth data, the types of land-use have changed due primarily to shore reclamation or wild land and grassland fostering before the eighties. After the mid-eighties, however, a number of private residents and commercial stores quickly have spreaded throughout beach resorts and quasi-agricultural and forest areas. Moreover, shore and community regions were severely damaged in the nineties with increased farmland, due to the development of tour places and expansion of city area. The predicted result of the environmental changes in the land-surface using the fuzzy logic operation was almost similar to the state of Anmyeon-do obtained through the satellite image. Particularly, the flat lands near the shore was predicted to change slightly. This area is largely under development, thereby raising concerns on the shore environment. Thus, this method is applicable to conducting research on the change in the land-surface.

지역개발의 결과인 지표환경의 변화를 예측하는 일은 지속 가능한 환경을 보전하기 위한 수단으로서 대단히 중요하다. 본 연구에서는 다중분광영상 자료를 이용한 퍼지논리연산을 통하여 안면도의 최근 20년(1901~2000) 간의 지표경관 변화를 예측하고 실제 변화된 내용과 비교 검토하였다. 안면도에 대한 문헌, 지도 및 현지 답사한 결과에 의하면, 1980년대 이전에 주로 해안간척과 황무지개간, 초지 조성 등으로 토지이용 형태가 변화되어 왔다. 그러나 1980년대 중반 이후부터는 해수욕장 주변과 준농림지역을 중심으로 민박시설과 점포 등이 무질서하게 들어섰으며, l990년대에는 관광지 개발 및 토시지역의 확장으로 농경지는 증가하였으나 해안지역과 취락지역의 산림이 심각하게 훼손되었다. 퍼지논리연산을 이용하여 지표환경 변화를 통합하여 예측한 결과와 2000년 위성영상에서 얻은 안면도의 지표환경은 비교적 정확하게 일치하였다. 안면도 지역에서 대규모 토지피복 변화가 일어날 가능성이 높은 지역들은 해안과 가까운 평지에 위치한 지역으로 예측되었는데 실제로 이 지역은 현재 대규모 개발이 진행 중이어서 연안환경 악화의 우려를 자아내고 있다. 따라서 본 방법은 향후 지표환경 변화 연구를 위한 효과적으로 적용될 수 있을 것으로 기대된다.
