초록

To conduct a comprehensive assessment of aquatic ecosystems, it is necessary to understand the characteristics of lentic ecosystems such as lakes, in addition to rivers. This requires analyzing the characteristics of biological communities in lakes and developing appropriate assessment indices. In this study, we analyzed the distributional characteristics of benthic macroinvertebrate communities collected from 90 lakes between 2022 and 2024, according to four categories of lake types (inflow stream type, lake size, salinity characteristics, and trophic states). The environmental variables used to classify lake types (catchment area, altitude, area of water, electrical conductivity, total phosphorus, and chlorophyll-a) all followed a log-normal distribution with positive skewness. Most of the lake types were characterized by inflow from lowland small streams, small or middle size, and freshwater lakes. However, in terms of trophic states, many lakes were assessed as mesotrophic or eutrophic. Analysis of seven community structure characteristics (taxa richness, taxa abundance, dominance, diversity, richness, evenness, and Lake Benthic Macroinvertebrate Assessment Index, LBAI) and two functional groups (feeding and habitat) showed clear changes primarily associated with trophic states, while other lake types showed irregular increase or decrease or similar levels. In the CCA, which analyzed dominant taxa by abundance and six environmental variables, the distribution patterns of lakes were more clearly distinguished by salinity characteristics related to electrical conductivity, unlike the community indices. The results of this study are expected to serve as basic data for future monitoring and assessment of lake aquatic ecosystems using benthic macroinvertebrates.
