Aquatic insects were researched from 18 sites in the Yongsan River System from August, 1988 to July, 1989. The monthly distribution and distributional pattern of the aquatic insects according to the environmental factors were investigated. Sensitivity, tolernace range and pollution tolerance index associated with each species were investigated. Also in order to use as a indicator organism, 36 species were selected and optimal BOD value and realtive frequencies of occurence were computed and examined. Polution tolerance indicies of mayflies ranged from 0.5∼5, stonflies from 0 to 2, caddisflies from 0 to 3.5, beetles from 1.5 to 3.5 and flies from 0 to 5. Chironomus showed the highest optimal BOD value of 23.7㎎/ℓ, and at that concentration the realtive frequency was 48.7, but it was represented by from 0.8 to 12.7㎎/ℓ and 17.4 to 57.2% in other species. Bioindicators were Drunella aculea, D. criptomeria of Ephemeroptera, Yoraperla KUa, Pteronarcys sacchalina, Archynopteryx KUa, Perlodes sp., Megarcys ochracea, Kiotina decorata, Sweltsa nikkoensis, Taenionema KUa, T. CUa of Plecoptera, Rhyacophila of Trichoptera, Tipula, Eriocera and Anthoca of Diptera in Ⅰ degree, and Serratella rufa and Chironomus in Ⅳ degree of water quality.

This study has been carried out to survey the community structure of aquatic insects in the Tamjin River from October, 1981 to August, 1982. Quantitatively collected materials are classified and dominance indices, diversity indices, similarity indices, according to each sites and seasons are mathematic analyzed and to determine the water quality by diversity indices. The results are as follows: 1. The aquatic insect fauna of the Tamjin River is composed of total 93 species, 54 genera, 30 families in 7 orders. 2. Common speices from all the site are 12 species and native species from each site are 24 species. 3. Composition of aquatic insect fauna according to insect order is as follows: Ephemeroptera 44 species, 16 genera in 9 families. Coleoptera 13 species, 10 genera in 6 families. Trichoptera 13 species, 8 genera in 5 families. Plecoptera 9 species, 9 genera in 4 families. Odonata 4 species, 4 genera in 1 families. Megaloptera 3 species, 2 genera in 1 families. 4. Component ratio of the number of individuals according to the insect orders is as follows: Ephemeroptera 68.0% Trichoptera 10.8% Diptera 8.9% Coleoptera 7.4% Plecoptera 4.4% Odonata 0. 6% 5. Epeorus curvatulus is a dominant species in the Tamjin River and Choroterpes trifurcata, Hydropsyche ulmeri, Potamantus sp. nb., Mateopsepheuus japouicus, and Ecdyouurus yoshidae are to make up the greatest population. Dominant indices of this River are 0.269 to 0.584. 6. Diversity indices represent 3.114 in the Tamjin River. 7. Similarity is very high at mid stream, and shows more high similarity between mid stream and lower stream than upper stream. 8. The biological estimation of upper stream of the Tamjin River`s water quality based on diversity indices is oligosaprobic zone and lowor stream belongs to β-mesosaprobic zone.

영산호의 (榮山湖) 육수학적 (陸水學的) 연구 - Ⅰ. 하구에 새로이 형성된 호수의 일반적 그리고 물리적 환경에 대하여 -

The limnology of Lake Yongsan, a freshwater reservoir recently built in the Yongsan Estuary, was studied in relation to physical conditions. The lake sampled for 14 months at monthly interval in 1983∼1984. Water temperature varied widely from a monthly average low of 1. 0℃ to a high of 30.7℃. Water structure was isothermal and homogeneous throughout the yearly survey. Salinity ranged from 0. 03 to 0.45‰ and tended to increase toward the barrier indicating some salt water intrusion. Extremely low transparencies prevailed throughout the survey period with Secchi disc depths ranging from 0. 25 to 1. 80 m. Conductivity was generally high with annual mean of 592.2 ㎛hos/cm while the annual mean pH range was 5.4∼9.4 with an annual average of 7. 2. The annual mean of alkalinity was 64.8 ㎎/ℓ. Dissolved oxygen content varied widely from 0. 90∼14. 44 ㎎/ℓ and had an annual mean of 8. 40 ㎎/ℓ. The BOD was relatively high, suggesting that allochthoncus organic material loading was occurring. The lake appears to be still in the early stages of development and has not yet reached equilibrium conditions. Other limnological factors are also described and discussed.
