초록

This study evaluated the impact of various landuse types (industrial, residential, and green areas) on river ecosystem health and biodiversity using benthic macroinvertebrates. Physicochemical water quality assessments, community structure analyses, functional group and indicator species analyses, and aquatic environment evaluations were conducted for rivers in the Anseongcheon watershed. The industrial area exhibited high water temperature (℃), high conductivity (μS/㎝), and low dissolved oxygen (DO, ㎎/L). Community analysis revealed that industrial areas had relatively high dominance and low diversity, whereas residential and green areas exhibited lower dominance and higher diversity. Functional group analysis showed that Collector-gatherers (CG) and Burrowers (BU) dominated the industrial area, whereas Clingers (CL) were more prevalent in the residential and green areas. Indicator species analysis identified the species associated with more diverse habitats in residential and green areas compared with industrial areas. Aquatic environment evaluations indicated that residential and green areas were relatively more stable than industrial areas but were still affected by urbanization. This study highlights the relationship between land use and river ecosystem health, and emphasizes the need for region-specific management and conservation strategies.
