Park, Se-Yeon Advisor: Prof. Lee, Yong-Bo Major in Biology Education Graduate School of Education, Chosun University

The present study was undertaken to classify and describe the vegetation around Kimcheon Buhangdam areas in Gyeongbuk province. The flora of Buhangdam areas was investigated from March in 2006 to March in 2007. South Korea (35°70′～ 36°00′N, 127°75′～ 128°00′E) by methods of the ZM school of phytosociology. As a result the vegetation was divided into twenty three associations and communities. The vegetation units obtained in the present study were as follows: Pinus densiflora community, P. thunbergii community, Quercus serrata - Q. variabilis community, Q. variabilis - Q. serrata community, Q. variabilis - Q. mongolica community, Q. mongolica - P. densiflora community, Q. acutissima - P. koraiensis community, Q. acutissima - Q. serrata community, Q. acutissima - Larix leptolepis community, Q. acutissima - Pinus rigida community, Q. acutissima - P. densiflora community, Q. acutissima - P. thunbergii community, P. densiflora - Q. acutissima community, P. rigida - Q. mongolica community, L. leptolepis - P. densiflora community, Q. variabilis community, Q. acutissima community, Q. serrata community, Q. variabilis community, Fraxinus rhynchophylla community, L. leptolepis plantation, P. rigida plantation, P. koraiensis plantation. Plants of this area consist of total 536 taxa, 2 forma, 67 varieties, 467 species, 336 genera, 107 families. A total of 16 families and 42 species of naturalized plants were found, with an urbanization index of 18.67%. Endemic Korean plants totalled 12 species. Based on the present phytosociological work, detailed discussion is presented here regarding the relation between the vegetation units and their environmental conditions restoration ecology and the natural conservation of the vegetation.
