월악산국립공원의 부착규조 분포와 유기오탁지수 (DAIpo)에 의한 수질평가

Distribution of Epilithic Diatoms Community and an Assesment of Water Quality by DAIpo in Woraksan National Park, Korea

본 연구는 2006년에 월악산국립공원 내에 부착규조류 분포와 유기오탁지수에 의한 수질 평가이다. 동정된 부착규조류는 138종류였고, 우점종은 Achnanthes sp. Achnanthes alteragracillima, Achnanthes convergens, Achnanthes minutissima, Cocconeis placentula var. lineata, Cymbella affinis, Cymbella silesiaca, Gomphonema minutum, Reimeria sinuata 등이었다. DAIpo 값은 62.3에서 99.9의 범위로, 매우 좋음에서 좋음으로 평가되었다.

To investigated the epilithic diatoms community and an assesment of water quality by DAIpo(diatom assemblage index of organic water pollution), the samplings were collected from fourteen sampling stations on April, May, August, September and October 2006 in Woraksan National Park. The total 138 taxa were identified from this study and dominant species were Achnanthes sp. Achnanthes alteragracillima, Achnanthes convergens, Achnanthes minutissima, Cocconeis placentula var. lineata, Cymbella affinis, Cymbella silesiaca, Gomphonema minutum, Reimeria sinuata. The variations of DAIpo values was ranged from 62.3 to 99.9 and the water quality was estimated between very good and good.
