Abstract

This study quantitatively verified the applicability of the ecosystem service assessment map, which was created using the Land Cover Map and InVEST, to 189 coastal dunes in South Korea. Through spatial data overlay analysis, the effectiveness of the ecosystem service assessment results for each dune was identified, and the item-specific applicability was compared. The analysis showed that items such as carbon storage, air purification, urban heat island mitigation, and baseflow contribution allowed for highly reliable assessment in most dunes. However, water purification and ecotourism items were found to have limitations in applicability due to the ecological characteristics of coastal dunes (soil and wetlands, resolution constraints). Furthermore, it was revealed that a spatial limitation—the omission of beach and tidal flat areas in the Land Cover Map—was influencing the assessment results. To compensate for these limitations, a method for integrating vegetation maps and land cover data based on regular vegetation surveys was proposed. This study confirmed the applicability of quantitative assessment for coastal dune ecosystem services and, by presenting constraints and improvement conditions for the utilization of national spatial data, is expected to be utilized as fundamental data for future coastal ecosystem service assessment and management policy establishment.

본 연구는 국내 189개 해안사구를 대상으로 토지피복도와 InVEST를 활용하여 제작된 생태계서비스 평가지도의 적용 가능성을 정량적으로 검증하였다. 공간자료 중첩 분석을 통해 사구별 생태계서비스 평가 결과의 유효성을 식별하였고, 항목별 적용성을 비교하였다. 분석 결과, 탄소저장·대기조절·열섬저감·기저유량기여도 항목은 대다수 사구에서 신뢰도 높은 평가가 가능하였으며, 수질정화·생태관광 항목은 해안사구의 생태 특성(토양과 습지, 해상도 제약)으로 인해 적용의 한계가 확인되었다. 또한 토지피복도에 사빈과 조간대 지역이 누락되는 공간적 한계가 평가 결과에 영향을 미치고 있음을 밝혔다. 이러한 한계를 보완하기 위해 정기적 식생조사에 기반한 식생도-토지피복 자료 융합 방안을 제안하였다. 본 연구는 해안사구 생태계서비스의 정량 평가 적용 가능성을 확인함과 동시에, 전국 단위 공간자료 활용의 제약 및 개선 조건을 제시함으로써 향후 해안 생태계서비스 평가 및 관리 정책 수립의 기초 자료로 활용될 수 있을 것으로 기대된다.
