Benthic Macroinvertebrate Community of Streams Located in Mt. Gyemyeong, Chungju-si

Abstract

πle benthic macroinvertebrate fauna were 39 species belon.잉ng to 10 orders of three classes in two phyla . by the quantita디ve sampling. Anlong them, a total of 35 aquatic inseα species (늑 90%) were cαnprised.of the major group in all communities. πle relative abundance of Plecoptera, Ephemeroptera, Diptera, and Trichoptera was 35.1%, 23.7%, 23.1%, and 11.7%, respectively .. The primary dominant species was Nemoura KUb (34.8%) and Chironomidae sp.1 (13.1%) , Ecdyonurus kibunensis (6.3%) , Nigrobae따 baci11us (5.7%), and Gammarus sp. (4. 9010) were shown the following dominance. According tó the results, plecopteran species were major dominant 없xa. πle average values of dominant index (DI), diversity index (H'), evenness index (J'), and species richness index (R1) were 0.543, 2.757, 0.720, and 3.590, respec디vely and the water quality of 외1 sites was ßmesosaprobic.
