영문 초록

The present study was accomplished from October, 1992 to June, 1993 in order to examine the seasonal community structure of aquatic insects and the biological estimation of water quality by the aquatic insects of the Jungneung and Gokneung streams in the Mt. Bukhan. The obtained results are as follows: 1. The total taxa of aquatic insects appeared as 77 species, 45 genera, 28 families in 7 orders. 2. Seasonal occurrence species numbers showed the highest in the autumn of the Jungneung stream (19 species) and in the spring of the Gokneung stream (41 species). Seasonal occurrence individual numbers showed the highest in the summer of the Jungneung and Gokneung streams (5,901, 3,180 individuals) and the lowest in the autumn of Jungneung stream (612 individuals) and in the winter of the Gokneung stream (1,764 individuals). 3. Annual dominance indices showed 0.52 (stJ1)~1.00 (st.J3) range in the Jungneung stream, and 0.47 (st. G1)~0.76 (G2) range in the Gokneung stream. 4. Seasonal species diversity indices showed 0.00 (st J3, whole seasons)~3.12 (st.J1, Spring) range in the Jungneung stream and 0.69 (st. G2, summer) ~3.10 (st. G4, spring) in the Gokneung stream. 5. Biological saprobic system based on species diversity indices of aquatic insects appeared as oligosaprobic area: site J3, $\alpha$-mesosaprobic area: site J2, G2, G3 and $\beta$-mesosaprobic area: site J1, G1, G4.
