Abstract

The conservation of wetland ecosystems has a significant role in climate change. Notably, the Han River Protected Area, including the Siam-ri wetland and Janghang wetland, provides high biodiversity value. Thus, it is necessary to comprehensively evaluate the function and value of wetland ecosystems. This study evaluated the ecosystem services of Siam-ri and Janghang Wetlands located in the Han River Protected Area using the Rapid Assessment Wetland Ecosystem Services approach, a function-oriented ecosystem analysis. The results were calculated using the Ecosystem Services Index formula to analyze wetland ecosystem services. We also assessed the key ecosystem services based on a focus group interview. We identified that the supporting and cultural services index scores were relatively high in the study area. The results can provide helpful information for sustainable wetland conservation, conservation planning as primary data, and raising awareness for the Han River Protected Area.

최근 생물다양성 증진, 기후변화 완화, 수질정화 등의 기능을 제공하고 있는 습지 생태계의 중요성이 강조되고 있다. 습지 생태계가 제공하는 서비스에 대한 평가는 조절서비스와 관련된 염습지, 갯벌 및 염생식물 등의 탄소저장 능력에 관한 연구 중심으로 진행되었다. 습지 생태계가 가지고 있는 기능과 가치를 종합적으로 평가한 연구는 부족하다. 이에 본 연구에서는 생태적 기능 중심의 평가가 가능한 습지 생태계 서비스 간이평가법을 이용하여 한강하구 습지보호지역이면서 람사르 습지인 장항습지와 람사르 습지로서 지정이 필요한 시암리습지를 대상으로 습지 생태계가 제공하는 서비스를 종합적으로 평가하였다. 습지 생태계가 제공하는 다양한 서비스를 생태적 특성에 따라 구분하여 평가하였으며, 이때 평가 척도는 5점 척도로서, 매우 긍정적 기여(++), 긍정적 기여(+), 무시할만한 기여(0), 부정적 기여(-), 매우 부정적 기여(--)로 설정하였다. 본 연구에서는 장항습지와 시암리습지를 대상으로 시범평가를 수행하였으며, 장항습지와 시암리습지가 제공하는 서비스를 질적으로 평가하였다. 시암리습지와 장항습지 생태계에 대한 생태계 서비스 인덱스(ESI) 평가 결과, 지원서비스와 문화서비스가 상대적으로 높게 도출되었다. 본 연구 결과를 통해 습지 생태계가 제공하는 다양한 서비스에 대한 생태적 가치를 재확인하였다. 이를 바탕으로 향후 습지 생태계 보전 및 생태적 관리정책 수립 시 기초자료로 활용될 수 있을 것으로 판단된다.
