Mt. Kumjeong is located in south-eastern part of the Korean Peninsular($129^{\circ}$01' to $129^{\circ}$05' E, $35^{\circ}$03' to $35^{\circ}$17' N) and the altitude of the summit is 802 meter. In order to find out the vegetation units which made it possible to classify subtropical forest and south-temperate forest, Mt. Kumjeong (which is located in a border of between subtropical forest and south-temperate forest) was selected as a study area. The primary result of actual vegetation analysis in Mt. Kumjeong based upon the vegetation community analysis methods by the ZM-school, and the relationships between vegetation community and two parameters(altitude, topography) analyzed by using coincidence analysis method were summarized as followings. 1. Based upon analytic methods of the vegetation community by the ZM-schools, the primary analytic result of the analysis of vegetation community in Mt. Kumjeong was divided into 10 communities, 9 groups, 2 subgroups. 2. Eurya japonica group of Pinus densiflora community out of 16 vegetation units was thought as a indicator vegetation group which made it possible to border subtropical forest and south-temperate forest. 3. Natural regeneration of Stewartia koreana group was thought to be difficult because seedling and sapling was rarely showed, 4. In relationship between vegetation units and altitude, Carpinus tschonoskii community, Quercus variabilis community, Quercus serrata community, Wisteria floribunda community,. Eurya japonica group of Pinus densiflora community, Pinus thunbergii community mainly distributed below altitude 500 meter, and Quercus mongolica community, Typical group of Pinus densiflora community, Quercus dentata community, Carpinus coreana community, Quercus acutissima community mainly distributed above altitude 500 meter. 5. In relationship between vegetation units and topography, Carpinus tschonoskii community, Quercus variabilis community, Quercus serrata community, Wisteria floribunda community,. Eurya japonica group of Pinus densiflora community distributed below middle slope, Quercus mongolica community, Typical group of Pinus densifiora community, Quercus dentata community, Carpinus coreana community, Pinus thunbergii community Quercus acutissima communily clistributed above midclle slope.

Juniperus chinensis forest were classified into 1 community group, 2 communities, 4 groups, 6 subgroups, and 7 vegetation units by phytosociological analysis(the method of ZM schools) with 79 vegetation data in south korea. By NMS analysis it appeared at first axis (13.8%) and second axis (69%) and comprehensive explanatory power was 31%. It was shown clearly in Donggang region, the East sea region and the Ulleungdo region. In INSPAN(Indicator species Analysis) of vegetation unit, 89 species were analyzed significantly. According to result of species diversity, evenness, dominance value, interspecific-competition and other related analyses for vegetation unit, the species diversity of vegetation unit 4 showed the lowest value 0.667, while the value of vegetation unit 6 showed the highest value 1.174. The dominance value of vegetation unit 7 showed the lowest value 0.163 and most vegetation units are on about 0.7, while the value of vegetation unit 1 showed highly above 0.8.

The Mt. Cheongok is located at the northern part of Kyungsangpookdo from $37^{\circ}$ 00' 00" to $37^{\circ}$ 05' 00" latitude and from $128^{\circ}$ 55' 00" to $129^{\circ}$ 00' 00" longitude. The altitude of the summit is 1,276.5m. This study was carried out to classify forest communities by the methods of Z${\ddot{u}}$rich-Montepellier schools. And, it also might be useful for selection of plant species, forest conservation, and prompting vegetation succession. The forest vegetation in Mt. Cheongok was classified into 12 communities, 4 groups, and 4 subgroups. Rhododendron micranthum subgroup of Pinus densiflora for. erecta community and Fraxinus mandshurica community were not found in cool temperate forest, southern zone yet. According to the coincidence method, Pines densiflora for. erecta community was mainly distributed from altitude 450m to 1,100m and from upper slope to ridge, and Quercus mongolica community was dominanced in the range of over altitude 700m. Pinus densiflora for. erecta community, distributed in upper slope and ridge, is judged to be maintained in the future. But Pinus densiflora for. erecta community, distributed in below middle slope, is judged to be changed into deciduous hardwood forest.

The objectives of this study were to classify the types of vegetation in Pinus densiflora for. erecta stands. The study sites were located at Sokwang-Ri, Mt. Chungok(1,276m), Uljin, Mt. Kumma(1,017m) and Mt. Eungbong(1,267m). Two hundred thirty releves were classified and explained by phytosociological analysis(the method of ZM schools), and the results were summarized as follows. Pinus densiflora for. erecta stands were classified into Vaccinium koreanum community, Rhododendron micranthum community, Quercus dentata community, Acer pseudosieboldianum community, and Typical community. Quercus dentata community was divided into Festuca ovina group, Robinia pseudoacacia group, and Typical group, and Acer pseudosieboldianum community was divided into Hydrangea serrata for. acuminata group, Disporum smilacinum group, Magnolia sieboldii group, Carpinus laxiflora group, and Typical group, and Typical community was divided into Melampyrum roseum group and Typical group. And some groups were divided into 7 subgroups. Therefore, Pinus densiflora for. erecta stands had total of 16 vegetation units, out of those units, Vaccinium koreanum community distributed all over the studied areas. While Rhododendron micranthum community distributed mainly at Sokwang-Ri and Mt. Chungok. Therefore it was considered to be useful indicator in determining the range of afforestation and natural distribution of Pius densiflora for. erecta stands. The classified vegetation units were investigated by using of coincidence method. The results indicated that Quercus dentata community distributed mainly below 100 meters at the sea level, while other communities distributed above 350 meters at the sea level. According to the correlations between vegetation units and topography, Vaccinium koreanum and Rhododendron micranthum communities distributed mainly above middle slope areas, Quercus dentata community distributed mainly from lower slope to upper slope areas, Acer pseudosieboldianum community distributed mainly between valley and lower slope areas, and Typical community distributed mainly above upper slope areas. According to the correlations between vegetation units and 5 study areas, Quercus dentata community was distributed in the region of Uljin, and other communities were evenly distributed over other studied areas. According to the correlations between the units and aspects, all communities occurred all aspects, but most of the communities tended to be more distributed at south slopes than at north slopes, which meant that the relic stands of Pinus densiflora for. erecta were remained largely as patch phase status at south slopes.
