Study on the Determination for Degree of Green Naturality in Cheolweon, Chunseong and Hwacheon Region

This study was carried out to determine degree of geeen naturality, in Cheolweon- gun, Hwacheon-gun, and Chunseong- gun, to surveyed the floristic composition of Mt. Myeongseong in Cheolweon- gun, Mt Seokryong in Hwacheon-gun, and Mt. Obong in Chunseon- gun, concentrated on this studied areas. The squre of studied areas were 2, 820㎢ and this area composed of 2, 665 meshes Nine different grades of green naturality; (1),(2),(3),(4),(5),(6),(7),(8),(9),(0) have been registered 1,673 meshes (62. 78%) out of 2, 665 were classified as the grade 8 and 389 meshes (14.6%) were the grade 7. The above data indicate that this areas composed of 20-50 years forests. Plant biomass, net production and oxygen production were estimated to be 15, 657, 330ton/year, 1,609, 590 ton/year, 1,706, 165.4ton/year in this area. Floristic composition of Mt. myeongseong (922.6m) was revealed to be 372 taxa, and that of Mt. Seokryong(1300m) wes 471 taxa, and that of Mt. Obong was 562 taxa. Among them 24 species were indigenous to Korea, including genera of Hanabusaya. It is interesting that north hemispheric plant. Astilboides tabularis was distributed at Mt. Seokryong.
