초록
본 연구는 지난 30년간 내륙수 생태계의 토지피복 변화를 계량적으로 분석하여, 내륙수 생태계의 장기적변화 추세와 주요 원인을 규명하고자 하였다. 이를 위해 환경부 대분류 토지피복도를 활용하여 1990년부터 2020 년까지 내륙수 면적 변화를 전국 및 대권역 하천유역별로 분석하였다. 연구 결과, 지난 30년간 전국 내륙수 면적의 67.5%가 유지되었고, 32.5%는 타 토지피복으로 전환되어 손실, 55.0%는 신규 생성되어, 과거 내륙수 면적의22.4%가 순증가된 것으로 파악되었다. 내륙수의 변화는 주로 댐 및 보 건설로 인한 신규 생성과 도시화로 인한손실로 나타났다. 이러한 분석 결과는 내륙수 생태계의 보전 및 관리 정책 수립에 유용한 정보를 제공하며, 장기적 생태계 변화 연구의 기초 자료로 활용될 수 있을 것이다.
Abstract
This study quantitatively analyzed the land cover changes in inland water ecosystems over the past 30 years to identify long-term trends and major causes of change. Using the Ministry of Environment’s land cover classification data, changes in the area of inland waters from 1990 to 2020 were analyzed nationwide and by major river basins. The results show that over the past 30 years, 67.5% of the inland water area nationwide has been maintained, 32.5% has been converted to other land cover types and lost, and 55.0% has been newly created, resulting in a net increase of 22.4% in the inland water area compared to the past. These changes were primarily attributed to new constructions such as dams and weirs, as well as losses due to urbanization. This study provides valuable insights for the conservation and management of inland water ecosystems and serves as a foundational reference for long-term ecosystem change studies.
