This study has investigated the growing features and vegetation of Acanthopanax chiisanensis and Acanthopanax koreanum in Mt. Jiri and Halla from Sep. 1997 to Aug. 1998. As to Acanthopanax chiisanensis, it occupied surrounding areas of Nogodan in Mt. Jiri of the height of 1,507m, ImgeolyoungJae of 1,300m and the Mt. Halla. of 1,100m of There were rather high constancy degree with Quercus mongolica, Schizandra chinensis, Hydrangen serrate for. acuminata, Acer pseudo-sieboldianum, Dryopteris crassirhizoma, Actaea asiatica, Thalictrum filamentosum, Abies koreana, Arundinella hirta from the sorts. The common species in Mt. Jiri and Halla are Acer pseudo-sieboldianum, Dryopteris crassirhizoma, Callicarpa japonica, Parthenocissus tricuspidata, Acer mono, Ligularia fischeri, Disporum smilacinum, Viola acuminata Aconitum kusnezofii. On the other hand, concerning of Acanthopanax koreanum community, it possessed the small areas of wedo weoltae village in Chejudo. In this area, a liana e.g. Dioscorea tenuipes, Hedera rhombea, Lygodium japonicum, Akebia quinata, Vitis thunbergii, Dunbaria villosa, Trachelospermum asiaticum var. intermedium, Vitis amurensis, Paederia scandens, lives with Pinux thunbergii, Celtis aurantiaca, Mallotus japonicus and so forth in tree layer and subtree layer. There is artificial change no move in the researching sites, Acanthopanax chiixanensis will be transformed into Abies koreana - Acanthopanax chiisanensis community. Soil characteristics showed the high value such as pH 6.56 and conductivity 0.258mmho/cm in Acanthopanax koreanum community of Mt. Jiri, they also indicated digit as follows: the content of organic matter and total nitrogen are from 25.16 through 25.35% and 7.58 through 9.30mg/g respectably. The soil characteristics at Acanthopanax chiisanensis community in Mt. Jiri and Halla, was high as like pH 5.76, conductivity 0.238mmho/cm, total nitrogen 9.30mg/g, total phosphorus 0.126mg/g in Mt. Halla.

To classify and analyze the forest communities and their structures, the vegetation in Mt. Joghe was investigated from July, 1980 to August, 1989. The results obtained are as follow ; 1. A total of 750 kinds of vascular plant(49 orders, 122 families, 434 genera, 627 species, 1 subspecies, 111 varieties and 11 forma)were observed in Mt. Ioghe. The newly observed plant species were Dioscorea quingueloba, Spiranthes sinensis, Cephalanthera falcata, Angelica gigas, Clematis patents, Paeonia obovata, Hibiscus mulabilis, Ainsliaea acerifolia, Dictamnus dasycarpus, Cynachum ascyrifolia, Vaccinium koreanum, Erythrortium japonicum, Indigofera kirilowii (17species), Broussonetia kazinoki var, humillis, Euonymus, fortunei var. radicans, Juniperus communis var, nippnnica, Callicarpa japonica var. radicans, Joniperus communis var. rzipponica, Callicarpa japonica var. taquetii (4 varieties) and L indera obtusiloba for. billosum (1 forma). 2. The life spectrum of flora in Mt. Joghe was classified into $CH-D_1-R_5-e$ type. Distribution area was identical to Southern type by Nakai, Lee, and Yim. A few subtropical species were also observed. 3. Simpson's species diversity index(Ds) was 0.9 and Shannon-Weiner's diversity index (H') was 1.004. These indice suggest that the vegetation in Mt. Joghe is of complicated forest communities. 4. Pte-Q was 1.81 which was higher than the nationwide mean of 1.68. Urbanization Index (UI) was 28.75 for naturalized plant species, and 17.49 for exotic woody plant species, which were similar to those of Mt. Baekun and Mt. Naejang. 5. The forest vegetation of Mt. Joghe was grouped in 3 vegetation types : 7 natural plant Communities dominated by Quercus serrat, Quercus acutissima, Quercus variabilis, Carpinus laxiflora, Pinus derasiflora and Platycarya strobilacea, 8 substitutional plant communities Styrax japonica, Stewartia koreana, Lindera erytlrrocarpa, Zelkova serrata, Rhtrs chinensis, Controversa, and Frzrxirtus manrlshurica, and 7 plantation Communities composed of Pinus koraiensis, Pinus rigida, Magnolia nbnvata, Chamecyparis obkrsa, Larie ieptolepis, Castanea crenata and Cryptomeria japonica. 6. Actual vegetation maps and profile diagrams were made by phytosocialogical classification. 7. As the important and unique species in Mt. Joghe, Lindera sericea, Penicaria tilitorme, Hex macropoda, Hex macropoda for. pseudo-macropoda, Steroartia koreana, Adenopkora palustris and Corylop.,is coreana, which were also seported by Lee(1977), Kim and Yark(1989), were identified and Vaccinium coreanum, Cremastra appendiculinium, Juniperus comminis van. nipponica, Cephalanthera falcata, Broussortetia kazinoki var. humilis, paeonia obovata, Deutzia prunifolia, Dictamnus dasyarpus, Angelica gigics and Bupleurum falcatum were odditionally observed.
