Abstract

This study was conducted from July to December 2004, in order to find measures to improve the water quality and the function of pond ecosystems which are often negatively affected by phytoplankton and suspended particle matters. Most of the time, the management of ponds in Korea does not consider the ecological concepts such as self-purification and nutrient recycling. Instead, conventional methods depend on other factors such as fish farming and the function of fountains and waterfalls. Sustainability of pond ecosystems must be studied with the highest emphasis given to water quality. Water discharges of inflow and outflow as well as balance adjustment for different factors must be thoroughly studied. There is a great need for studies on sustainability because it can be realized through the horizontal or vertical balances of an ecosystem. Our current research offers useful information to the academia and public on maintaining sustainability in terms of structure and function of the pond.

본 연구는 식물플랑크톤과 입자성 부유물질에 의해 수질문제를 야기하는 연못의 수질개선과 생태계의 기능 향상을 위해 2004년 7월부터 12월까지 수행되었다. 국내에서 대다수 연못의 관리는 자정작용과 물질순환의 생태학적 개념을 고려하지 않고 있었다. 다른 요인보다도 분수, 폭포 및 어류생물 사육에 의존되었고, 이러한 요인의 유무에 따라 수질 차이가 매우 큰 것으로 파악되었다. 연못 생태계 유지의 지속 가능성은 수질이 최우선으로 고려되는 기반이 제공되어야 한다. 물의 유입량과 유출량의 적절성과 함께 각 요소간 비율의 평형 조절이 무엇보다도 중요하다. 지속 가능성은 하나의 계에서 수평 또는 수직적 균형을 이룰 때 실현될 수 있기 때문에 이에 대한 연구 결과가 반드시 필요하다. 본 연구 결과에서 연못의 구조와 기능적 문제점이 도출된 데 대해 이러한 지속가능성을 유지하는데 가치 있는 유용성을 제공하게 되었다.
