1 이상훈 심재국 Vegetation of Mt. Yeonin Provincial Park Department of Life Science, Chung-Ang University The forest vegetation of Mt. Yeonin Provincial Park was surveyed from August 2016 to October The vegetation was classified into the following eight main communities according to the physiognomic dominant species: Q. mongolica, P. koraiensis, P. koraiensis-q. mongolica, Q. varilablis-q. mongolica, L. kaempferi, P. densiflora, Q. mongolica-a. holophylla, Q. mongolica-p. rigida. The Q. mongolica community occupied 61.4% of the total vegetation area, occupying the largest area, followed by P. koraiensis community, P. koraiensis-q and Q. varilablis-q. mongolica community. Q. mongolica communities were mainly distributed in the peaks and ridges, and P. koraiensis community and P. koraiensis-q. mongolica community were frequent in the valleys and lowlands. The vertical structure of the major communities of Mt. Yeonin Provincial Park represented four layers. For each layer, the height and coverage appeared to vary depending on the type of vegetation. Analysis of frequency distribution of DBH-class showed that the Q. mongolica community, P. koraiensis community, Q. variabilis-q. mongolica community were expected to maintain the community in the absence of external interference. The degree of green naturality(dgn) of this region was 66.4% in DGN 7, 31.4% in DGN 6, 0.2% in DGN 2, 1.5% in DGN 1, and 0.5% in DGN 0. The net primary productivity (NPP) was assumed as 1, g/m 2 /yr(use temp.) by Miami model, and 1,457.30g/m 2 /yr by Montreal model, respectively. In order to preserve and restore the natural vegetation of Mt. Yeonin, it is necessary to manage the plantation and to develop it according to thorough plan. It is also necessary to monitor and monitor naturalized plants continuously. 서 론,,. 1,068m, 2,,,.,,.
