The purpose of this study was to select resistant species against SO₂ pollution. We identified the recovery patterns of photosynthesis after SO₂ exposure in Quercus accutissima, Pinus densiflora, Populus alba x P. glandulosa and Acanthopanax sessiliflorus. Plants were exposed to SO₂ (mean concentration 500 ppm) for about 6 h/day (10:00~16:00) for 20 days. Quercus accutissima and Pinus densiflora maintained high photosynthesis and did not show visible damage symptoms after exposure. In contrast, Populus alba x P. glandulosa and Acanthopanax sessiliflors had significant reduction in photosynthesis following So₂ exposure and showed visble necrosis.

N/A This study evaluated forest vegetation structure according to elevation in Mt. Sokri and Odae. The dominance of Pinus densiflora, Quercus variabilis, Quercus serrata, Prunus serrulata var. spontanea was apparent at elevations below 500 m. Quercus mongolica, Fraxinus sieboldiana, Acer pseudosieboldianum and Symplocos chinensis for. pilosa were conspicuous above 800 m. Significant P. densiflora, Rhus trichocarpa, Lindera obtusiloba and P. serrulata var. spontanea populations appeared below 700 m elevation in Mt. Odae. Q. mongolica, F. sieboldiana, A. pseudo-sieboldianum, Tilia amuresis, Abies holophylla, Carpinus cordata, Betula costata, Kalopanax pintus and Pinus koraiensis were conspicuous at elevations 1000 m and above. P. densiflora, Q. monoglica, Q. serrata, R trichocarpa and L obtusiloba populations were significant at elevations below 700 m. Q. mongolica, F. sieboldiana, A. pseudo-sieboldianum, T. amurensis, A. holophylla, C. cordata appeared at elevations above 1000 m.
