The study was carried out to discover the forest vegetation structure in Hongdo Island, Jeonnam province. Vegetation data were collected by total of forty one quadrate plots using Z-M phytosociological method from June to August in 2017, and analyzed by vegetation classification, mean importance value and species diversity. As a result of vegetation type classification, Castanopsis sieboldii community group was classified at a top level of vegetation hierarchy. In the level of community, it was classified into Neolitsea sericea community and Carpinus turczaninowii community. N. sericea community was subdivided into Ficus erecta group(Vegetation unit 1) and Arisaema ringens group(VU 2). C. turczaninowii community was subdivided into Fraxinus sieboldiana group(VU 3) and C. turczaninowii typical group(VU 4). Therefore, it was classified into total of four vegetation units(one community group, three communities and four groups). As a result of mean importance value, Castanopsis sieboldii was the highest in VU 1, VU 2, VU 4, and C. turczaninowii in VU 4, respectively. In case of species diversity, VU 3 showed the highest among four units in species diversity index. In conclusion, the forest vegetation of Hongdo Island was classified into four units and seven species groups. Hongdo Island could be conclusively managed by community ecological approach for the units and groups. Also it was considered that a research for the succession to the evergreen broad-leaved forest should be more intensively proceeded near future.

The taxonomy of the broad-leaf evergreen trees (4 genera, 5 species) of Lauraceae was studied by the morphological characteristics of stipules. The results obtained were summarized as follows; 1) The stipules of Lauraceae were arranged alternately with 5-31 stipules of simple leaf. The venations or stipules were basal reticulate and pinnated vein. The shapes of stipule blade were oblong, oblanceolate, rhomboid and oval. The stipule apex was acuminate and obtuse, the stipule base was attenuate, and the stipule margin was entire margin. The trichomes of stipules were sericeous, tomentose and villous. The five species of Lauraceae could be identified by the morphological characteristics of stipules. 2) The morphologically changing forms of stipule vein were classified into three groups; A form - the form of pinnate vein with the distinguished main vein (lozoste lancifolia), B form - the three vein grows into the form of basal reticulate vein (Neolitsea sericea, Cinnamomum japonicum and C. camphora), C form - the parallel vein grows into the form of basal reticulate vein (Marhilus thunbergii). 3) The changing forms of stipule's width from stipule "a" to "j" were three forms; (1) a>d>g>j form: C. japonicum, C. camphora and I. lancifolia, (2) a>cj,(aj,(a

To propose basic information for national resource management and planting disign, plant community structure of evergreen broad-leaved forest was investigated. Fifty-two plots(each size 300m$^{2}$) were set up at Ch'omch'alsan area of Chindo, Korea. TWINSPAN and DCA methods were used for classification and ordination analysis. Fifty-two plots were divided into seven groups, which were Quercus variabilis-Carpinus tschonoskii community, Q. glauca community, Castanepsis cuspidata var. sieboldii-Q. stenophylla community, Castanopsis cuspidata var. sieboldii-Camelia japonica community, Q. acuta-Camelia japonica community, Carpinus coreaca-Q spp. community, C. coreana community. Pinus densiflora almost have been selected. Carpinus tschomoskii, Q. variabillis and Q. serrata were to be succeeded by Castanea cuspidata var. sieboldii, Q. stenophylla, Q. acuta and Neolitsea sericea in canopy layer. And Neolitsea sericea, Q. glauca and Camellia japonica was showed high importance values in fertile soil condition. Future restoration plan was necessary for a tourist resort or national forest in warm temperate region. And evergreen broad-leaved plants shall be planted in considering of environmental condition at warm temperate and industrial complex area.

As a serials of researches for the restoration model of evergreen broad-leaved forests, the restoration strategies of the case study areas were proposed. Restoration type of vegetation were classified into an improvement type and a reconstruction type and a reconstruction type for Wando(Island). Improvement type of restoration was suggested for Mokdo(Island). Quercus acuta community, Q. salicina community, Neolitsea sericea community, Castanopsis cuspidata var. sieboldii community, Machilus thunbergii community, Cinnamomum japonicum community, etc. were suggested as a restoration goal of vegetation for Sando(Island). Machlus thunvergii community was suggested as a restoration goal of vegetation for Mokdo(Island). Also the species restoration olan of the Wando(Island) was prepared for Quercus salicina of Fagaceae and Ostrya japonica of Betulaceae those which the natural distribution and population size were very limited. There was no species which needed for species restoration urgently at Mokdo(Island).

To study the actual vegetation and vegetation structure of Tongyoung district and Yokjido (Island) in Hallyo-Haesang National Park, thirty seven plots were surveyed in July,1998. The vegetation structure of the surveyed plots were dissimilar in virtue of geographical isolation and artificial disturbance. The actual vegetation were classified into five group: Pinus thunbergii forest, P. thunbergii-P. densiflora- deciduous broad-leaved forest, deciduous broad-leaved forest, P. thunbergii-P. densiflora-evergreen broad-leaved forest, evergreen broad-leaved forest. P. thunbergii forest was a major vegetaion type of the surveyed area and evergreen broad-leaved forests were distributed at Ch'ubongdo, Yongch'odo, Pijindo, Yokjido and Youjado as a small patch. Successional sere shall be assumed from Pinus thunbergii, Pinus densiflora, and deciduous broad leaved trees to Neolitsea sericea, Cinnamomum japonicum and Persea thunbergii via Castanopsis sieboldii.

The vegetation of Saeng-il Island was surveyed over four times from July, 1979 to May, 1981. The results obtained are summarized as follows: Plants of this island consisted of 3 foma, 28 varieties, 211 species, 203 genera, and 89 families. Evergreen broad-leaved trees consisted of 24 species, including Camellia japonica and Castanopsis cuspidata var. sieboldii. The vegetatiion of the southwest slope was more favorable than that of the northeast slope and the vegetation of other areas were negligible. Pueraria thunbergiana and Clerodendron trichotomum were predominant in the area between Yucheon-ri and Geummo-ri. Evergreen broad-leaved trees, such as Camellia Japonica, Neolitsea sencea, Castanopsis cuspidata var. sieboldii, etc. were predominated in the areas of Gulzeon-ri, Yongchul-ri and Geummo-ri. However, artificial succession to pinus thunbergii presently dominating the areas has taken place due to human interferences (for charcaol, building materials, grazing etc.). It seems to be worthy of conserving the community of Camellia japonica on the back slope of Geummo-ri and that of Castanopsis cuspidata var. sieboldii between Gulzeon-ri and Hangdo-dong. It is notceable, in particular, that Damnacanthus indicus distributed in Jeju and Dolsan islands was also discovered in this island.

The flora of vascular plants of these sites were listed 272 taxa; 80 families, 193 genera, 234 species, 32 varieties, 5 forms and 1 hybrid. The naturalized plants were 12 taxa, and naturalization rate was 4.4%. Specific plants by floral region were total 54 taxa; 4 taxa in class IV, 10 taxa in class III, 5 taxa in class II, 35 taxa in class I. There is no taxa in class V. A peculiar point is that we found more than 30 Allium pseudojaponicum in Allium genus which is known as Japanese endemic plant. In Gokdudo, there is large Carex boottiana community, in Daehangdo, Machilus thunbergii community covers the whole island. In Bulgeundo, most of the hundreds of trees including Neolitsea sericea and Machilus thunbergii planted by Korea National Parks in 2003 have been damaged by rabbits.
