초록

Wetlands are one of the most representative groundwater dependent ecosystems(GDEs) that require access to groundwater ona permanent or intermittent basis to maintain their biological communities and ecological processes. In this study, theseasonal characteristics of the GDEs in Baekseok Reservoir Wetland were evaluated through the monitoring of thetemporal and spatial community of benthic macroinvertebrates in the wetland. The appearance of benthic macroinvertebratesappearance was changed seasonally depending on environmental factors such temperature, precipitation and water levelfor their habitat and it also showed the clear spatial difference in the wetland. The scores of Diversity index(H’), RichnessIndex (R1) and the Ecological score of benthic macroinvertebrates (TESB/AESB) were relatively high at St.3 and 4(i.e.,north area) where groundwater inflows into wetland(i.e., high 222Rn conc.). The statistical analysis (ANOVA test andPCA) investigated the correlation among the benthic macroinvertebrates’ community, groundwater level, wetland waterlevel and water quality. The results showed that the community of benthic macroinvertebrates at St. 3 and 4 in BaekseokReservoir Wetlands was spatially dependent on groundwater level and groundwater inflow. The characterization andassessment of GDEs requires understanding the hydrological, biogeochemical and biological process and this study willprovide information for characterization and assessment of GDEs.
