This study demonstrates the investigation of zooplankton communities (e.g. rotifers, cladocerans and copepods) and environmentally related driving factors (e.g. elevation, area size, water depth, types of dike construction, and bottom substrates). We hypothesized that zooplankton community structure and composition would be influenced by ambient driving forces in different scales of the irrigation ponds (Dumbeong). A total of 66 zooplankton species/groups (56 rotifers, 9 cladocerans, 1 copepods) were found and identified at 45 Dumbeong of Goseong region (i.e. Goseong-gun) in 2011. The rotifers occupied 84.9% of the total zooplankton abundance. We could categorize a clear separation of zooplankton communities into 4 different patterns based on cluster analysis. Zooplankton diversities in Dumbeongs were lower than those in natural ponds or wetlands. In addition, community structure of zooplankton was also simpler and had a broken stick distribution based on SHE analysis. Species composition in each Dumbeong was not significantly discriminated each other. The result of canonical correspondence analysis (CCA) pinpointed that significant influential variables upon zooplankton community were dissolved oxygen percent saturation, pH, and Dumbeong’s material. This study indicated that morphological type of the Dumbeong and its water quality could determine the community structure of zooplankton. Furthermore, the connectivity between ambient habitats and materials could be necessary to be rigorously considered in respect to producing the Dumbeongs to subsidize alternative habitats for wetland ecosystem in freshwater landscape.

인간 간섭에 영향을 크게 받는 인공호소가 대부분인 우리나라의 호소 특성과 보다 나은 생태계 관리 방안을 도출하고자 하는 목적에서 2005년 4개 호소의 이화학적 요인과 담수조류 정량분석에 의거한 기초자료를 바탕으로 통계학적 분석을 시도하였다. Canonical Correspondence Analysis(CCA)를 하구호인 남양호, 삽교호, 아산호 및 북한강 중하류 수계에 연쇄적으로 위치한 댐호 중 하나인 청평호에 적용하였다 그 결과, 청평호는 3개 하구호와 구분되는 특징을 보였으며, 청평호를 제외한 CCA결과, 아산호-삽교호-남양호 간에도 차이를 보여주었다. 담수조류 군집 구성은 제한된 자료량 때문인지 해석이 생태학적 해석에 어려움이 따랐다. 따라서, 보다 지속적이고 심화된 담수조류 연구 및 기타요인의 채집 및 분석이 수행될 필요가 있음이 나타났다. 그러나, 제한된 자료량에도 불구하고, 청평호 및 3개 호소의 큰 두 그룹으로 호소 그룹이 특징지워진 것은 CCA 적용이 유효함을 나타낸 것으로 보인다.

CCA (Canonical Correspondence Analysis) was used so as to analyze the relation between vegetation and soil environment of Mankyeong river located in Jeollabuk-do. Vegetation survey consulted 1:5,000 topographical map, set up 30 plot and analyzed from June, 2001, to september, 2001. Plant communities of Mankyeong river was investigated by phytosocialogical method. The species composition of plant communities showed high correlation to soil pH, soil organic matter, P2O5, total nitrogen, EC, when they were analyed by CCA. According to the results of CCA hydrophyte communities were distributed in the region that high pH. But the vegetation of disturbed site and wetland plants were distributed in a good nutrients.
