The purpose of this study was to investigate the distribution of epiphytic lichens that growing near the thermoelectric power plant to obtain a basic data for air environmental evaluation around the power plant. The study areas were all 12 places including ten sites near the power plant and two sites for control. All the number of lichens appeared in this study areas were 27 species. It showed to 4∼6 species within 4㎞ from the power plant, and coverage also was low. As receding from the power plant, both the number of species and overage increased. Parmelia tinctorum sensitive to air pollution did not appear within 4㎞ from the power plant, and it was regarded as the sensitive kind to air pollution. Lepraria sp.(13.40%), Parmelia austrosinensis (13.40%), and Dirinaria applanaita (13.40%) were distributed in all sites, and it could infer that they had tolerance to air pollution. The IAP (Index of Atmosphere Purity) values in Sadungdong Apsan, Seksangeabal and the Power plant were four times as low as those in Mt, Yeonwha, and it could infer that the air in those areas was not good. It was high IAP values as being distant from the power plant.
