초록
폐광산 주변 오염지역의 식생복원에 이용할 목본 수종을 선발하기 위하여 본 연구를 수행하였다. 먼저, 폐광산 지역의 식생을 조사하고, 현지 오염 토양에 자생하는 목본식물의 중금속 오염도를 분석한 결과, 대부분의 지역에서 소나무, 아까시나무, 싸리, 오리나무 등이 넓은 면적을 차지하고 있었고, 다른 수종에 비해 생육 상태도 양호하였다. 이 수종들은 체내 중금속 농도도 높게 나타났으며, 특히 뿌리 부위에서 높은 값을 보였다. 이들 네 목본 수종을 대상으로 비오염토양과 가학광산(Cd, Cu, Pb, Zn 오염지) 및 금정광산(As 오염지)토양의 배합 비율별 종자 발아 특성을 연구한 결과, 발아율은 온실과 incubator 실험에서 모두 소나무 > 싸리 > 아까시나무 > 오리나무 순으로 나타났다. Incubator에서는 소나무와 오리나무의 발아율이 비오염 토양에서 가장 높게 나타났다. 소나무의 발아율은 가학광산 토양의 경우 100% 처리 수준에서 높게 나타난 반면, 금정광산 토양의 경우 광산 토양의 비율이 증가함에 따라 감소하는 현상을 보였다. 온실에서 소나무의 발아율은 가학광산 토양의 경우 40% 처리 수준에서 가장 낮은 반면, 금정광산 토양의 경우 20% 처리 수준에서 발아율이 가장 낮았고 광산 토양의 비율이 증가할수록 소나무의 발아율이 증가하였다. 유묘 생장의 경우, 금정광산 토양 20% 수준을 제외한 두 광산 토양의 모든 처리구에서 지상부 생장은 싸리가 가장 높았으며, 지하부 생장은 아까시나무가 가장 높았다. 본 연구 결과는 중금속 오염현장에 실제로 적용될 Eco-tree 선발을 위한 기초 자료로 사용될 수 있을 것으로 기대된다.
Abstract
This study was carried out to select the Eco-tree for successful phytoremediation of abandoned metalliferous mines. We examined vegetation and heavy metal concentrations of woody plants in abandoned mining areas, and also conducted seed germination and seedling growth experiments on contaminated soils from Gahak and Geumjeong mines. Pinus densiflora, Robinia pseudoacacia, Lespedeza bicolor and Alnus japonica showed high frequency in the survey areas and had high heavy metal concentrations compared to other species. Heavy metal concentrations were higher in roots than in leaves and stems. The seed germination rate was in the order of P. densiflora, L. bicolor, R. pseudoacacia, and Alnus japonica from the incubator and greenhouse experiments. In the incubator experiment, germination rate was highest in the control soil for P. densiflora and A. japonica. Germination rate of P. densiflora was highest on the 100% contaminated soil for Gahak mine while germination rate decreased with increased percentage of contaminated soil for Geumjeong mine. In the greenhouse experiment, germination rate was lowest on the 40% contaminated soil for Gahak mine while germination rate was lowest on the 20% contaminated soil for Geumjeong mine and increased with increased percentage of contaminated soil. Shoot growth was highest for L. bicolor while root growth was highest for R. pseudoacacia except for 20% contaminated soil in Geumjeong mine.
