Abstract

Constructed wetlands (CWs) have been accepted as an attractive and economic alternative to a variety of pollution control and provided potentially valuable wildlife habitat in urban and suburban areas, as well as esthetic value within the local natural environment. CWs are known eco-friendly technology to solve the problem of the climate change and urbanization issues. Numerous studies have been published on the various aspects of a CW. However, there are current limitations about the CW operations such as few design guidelines, poor performance results regarding the simple construction. Therefore, the objective of this research was to suggest an appropriate design and maintenance guidelines for a CW by thorough investigation of site monitoring results. The research also concentrated in redefining and reclassifying CWs, based on literatures made by the Ministry of Environment (MOE) and other organizations. Investigation at 43 CWs in Korea was performed by using collected data and by performing site survey from 2013 to 2014. Based on the results, the best practices among the investigated CWs provided water treatment, wildlife habitat, environmental education, and leisure. Also these CWs conducted a regular maintenance such as vegetation, sediment dredging and cleaning of facilities. Results obtained are intended for use by academics and any organizations involved in CW management.

인공습지는 물순환, 생태, 수질정화, 경관, 심미적 기능 등의 융합적 기능을 가지고 있어 다양한 분야에서 적용되고 있다. 특히 기후변화와 토지이용의 고도화 문제를 해결할 수 있는 자연친화적 기술로 알려져 있으며, 전 세계적으로 활발한 연구가 이루어지고 있다. 국내에 조성된 인공습지는 다양한 형태와 목적으로 적용되고 있으나 설치, 운영 등에 대한 가이드라인이 체계적으로 제시되어 있지 않아 단순 토목, 조경 위주의 습지 조성으로 인공습지의 고유기능 발휘에 한계를 보이고 있다. 본 연구는 인공습지의 적정 설계, 유지관리 및 사후운영 방안 등을 제시하기 위해 국내에 조성된 인공습지에 대한 현장조사를 실시하였으며, 인공습지의 개념 정립 및 분류체계를 확립하기 위해 환경부 및 기타 기관에서 분류하고 있는 인공습지의 분류체계에 대하여 조사였다. 인공습지 현장조사는 2013년부터 2014년까지 43개 지점의 인공습지를 대상으로 실시되었다. 현장조사를 실시한 인공습지 중 우수사례로 꼽힌 인공습지는 공통적으로 수변공간 제공, 오염물질 정화기능, 생태서식처 제공 등의 다양한 기능을 발휘하고 있는 것으로 나타났으며, 식생, 퇴적물, 시설관리 등의 유지관리가 적절하게 수행되는 것으로 분석되었다. 현장조사 결과를 바탕으로 인공습지의 적정 설계 및 유지관리 방안을 제시하였으며 이러한 결과는 실제 현장에서 활용 가능할 것으로 판단된다.
