초록
연못형습지(Pond Wetland)는 우리나라 농업경관에서 많이 분포하고 있다. 이러한 연못형습지는 생물다양성을 위한 중요한자원으로 평가 받는다. 하지만 연못형습지(Pond Wetland)에 대한 연구는 유형분류에 그치고 있다. 따라서 본 연구는 연못형습지의 생태계서비스(Ecosystem Service) 기능을 알아보았다. 연구방법은 총 3단계로 기능분석, 기능도출, 중요도 분석의순으로 진행하였다. 선행연구를 분석하여 총 22가지의 기능을 도출하였다. 전문가 설문 결과 22개 항목 중 생물, 환경, 사회문화 분야에 각 4 기능씩 총 12개 기능으로 선별하였다. 항목간 AHP(Analytic Hierarchy Process)를 실시하여 기능별 중요도를 산출하였다. 중복된 기능은 통합하여 연못형습지의 생태계서비스 기능 10가지(1. Water Storage & Irrigation, 2. Vegetation Diversity, 3. Amphibian & Reptile Habitat, 4. Water Purification, 5. Aquatic Insect Habitat, 6. Nutriments Control,7. Groundwater Recharge, 8. Fishery Habitat, 9. Eco-Experience & Education, 10. Aesthetic landscape)를 도출하였다. 향후 기능별 중요도 분석과 경제적 가치 지표를 적용하여 연못형습지의 생태계서비스 평가에 활용 할 수 있을 것으로 판단된다.
Abstract
A lot of Pond Wetland (Palustrine Wetland) are distributed in agricultural landscapes, Korea. These wetlands are evaluatedas important resources for conservation of biodiversity. However, the study of Pond Wetland is rarely conducted except typeclassification in Korea. In this study, the function of pond wetland as ecosystem services is studied for conservation andutilization of wetland. Research was conducted in three steps; functionality analysis, functionality derivation, and importanceanalysis. A total of 22 features were derived by analyzing the previous studies. As a result of expert survey, 4 featureswere selected by each in the field of biological, environmental, and socio-culture among the 22 features. Importance wascalculated by conducting a cross-functional features using Analytic Hierarchy Process (AHP). Finally, 10 ecosystem servicefunctions of pond wetland were derived through expert survey; (1) Water Storage & Irrigation, (2) Vegetation Diversity, (3)Amphibian & Reptile Habitat, (4) Water Purification, (5) Aquatic Insect Habitat, (6) Nutriments Control was derived, (7)Groundwater Recharge, (8) Fishery Habitat, (9) Eco-Experience & Education, and (10) Aesthetic landscape. It is expectedthat this study is able to utilize in evaluation of pond wetlands ecosystem services by further study on analysis offunctional importance and economic value index.
