Abstract
The purpose of this study was to investigate the influence of air pollution using epiphytic lichens on forest trees around Ulsan and Onsan industrial complex from April to June, 1997. The distribution of lichens was investigated at 58 sampled sites. In this study, 16 kinds of epiphytic lichens were recorded, of them, Lepraria sp. having a tolerance to air pollution showed the highest frequency as 30.85%, and in order of Lecanora strobilina(26.18%) and Parmelia austrosinensis(13.42%) unknown to tolerance of air pollution. The number of lichens was gradually decreased around industrial complex, where so - called "lichen desert" was detected. As being distant from the industrial complex, the mean degrees of cover were increased. The degrees of cover in the investigated sites ranged from I to V. According to
대기오염이 심한 것으로 판단되는 울산지역의 석유화학공단과 온산공단을 중심으로 수목착생지의류를 이용한 대기환경의 오염정도를 평가하기 위하여 공단 주변의 산림에서 지의류의 출현종수와 피도, 생육한계분포농도에 따른 분포특성과 대기청정도지수(IAP)를 조사한 결과, 조사지점에서 출현한 지의류는 총 16종류였으며, 그중 Lepraria sp.(30.85%)과 Lecanora strobilina(26.18%), Parmelia austrosinensis(13.42%) 등이 우점하고 있었다. 석유화학공단과 온산공단 주변 조사지점에서는 지의사막대(地衣砂漠帶)의 형성과 더불어 공단으로부터 멀어질수록 출현종수가 증가했다. 조사지점별 평균피도는 I-V계급으로 오염물질이 공단이 위치하는 해안가로부터 내륙으로 유입됨을 추측할 수 있으며, 공단으로부터 멀어질수록 평균피도계급도 증가하였다.
