The objectives of this study were to analyze the fish community structures and distribution characteristics of fisheries resources in the Osip Stream and Wangpi Stream, fishery resources protection areas. For the study, we conducted fish samplings four times in the two streams from April to October 2019. In Osip Stream and Wangpi Stream, we sampled 31 species and 29 species and the dominant species were Zacco platypus (28.6%) and Squalidus multimaculatus (41.7%), respectively. According to the life type of fish species, primary freshwater species were collected 18 species (58.1%) and 21 species (72.4%), and migration fishes were sampled 4 species (12.9%) and 6 species (20.7%) in Osip Stream and Wangpi Stream, respectively. Fisheries resources species showed high relative abundance in June, and the fish biomass was highest in October. As a results of comparing the previous studies with this study, both rivers showed high biodiversity and were found to maintain stable populations of fishes. According to analysis of tolerance guilds, the proportion of tolerant species, based on the number of individuals, was composed of 14.4% and 1.1% in Osip Stream and Wangpi Stream, respectively. This very low ratio of tolerant species confirmed that both streams have very good physiochemical environment conditions. From the above results, it was judged that the fishery resource protection areas of Osip Stream and Wangpi Stream have high ecological function and preservation value. For sustainable use and management of fishery resource protection areas of Osip Stream and Wangpi Stream, it is suggested that biological disturbance management, fish discharge projects considering environmental capacity, efforts to improve the habitat environment, and establishing a fishery resource protection areas management system were necessary as considerations.

본 연구는 강원도 도계광업소 수계에 발생한 적갈색침전물을 대상으로 침전환경을 파악하고, 중금속함량, 광물조성 및 그에 따른 분광학적 특성을 분석하였다. 적갈색침전물의 pH 범위는 7.59-7.94로 침전환경은 중성에 해당한다. X선형광분석 결과 철이 평균농도보다 높게 검출되었으며, 니켈, 구리 및 아연의 오염도가 높은 것으로 판명된다. X선회절분석 결과 돌로마이트, 방해석, 침철석, 자철석, 고령토, 엽납석, 석영 및 알루미늄 이소프로폭사이드의 광물이 확인되었다. 중금속 오염에 따른 분광학적 특성을 분석한 결과, 중금속함량이 증가함에 따라 가시광선 영역에서는 반사도가 증가하는 추세를, 적외선 영역에서는 반사도가 감소하는 추세를 보인다. 적갈색침전물의 분광특성은 침철석, 자철석, 고령토, 엽납석 및 알루미늄 이소프로폭사이드에 의해 발현되는 것으로 판단된다.
