This research was carried out from April to December 2014 in order to figure out the forest vegetation of Daeheuksan Island Forest``s vegetation. Forest vegetation is largely subdivided into the Evergreen Broad-forest, Coniferous forest, Deciduous broad-leaved forest, Plantation, Wetland vegetation, Rock vegetation, Forest edges-Shrub vegetation, Grassland vegetation and other areas that include 30 communities of forest vegetation and 4 communities of other areas. Thus in total, 34 communities were researched. Forest vegetations based on the physiognomy classification were 7 communities of Evergreen Broad-forest, 16 communities of Coniferous forest, 3 communities of Deciduous broad-leaved forest, 2 communities of Artificial afforestation, 2 communities of Wetland vegetation and 4 other areas vegetation. As for the distribution rate for surveyed main communities, Castanopsis cuspidata var. sieboldii community accounts for 34.28 % of the total forest vegetation. The Pinus densiflora-Carpinus turczaninowii community accounts for 8.83 % of the total forest vegetation, and the Pinus densiflora-Castanopsis cuspidata var. sieboldii community accounts for 5.05 % of the total forest vegetation, while the Carpinus turczaninowii community accounts 3.11 % of total forest vegetation, and the Plantation, 0.09 % of total forest vegetation. In conclusion, minority species of the Castanopsis cuspidata var. sieboldii and Machilus thunbbergii were distributed as dominant species of the uppermost part in the forest vegetation region of the Daeheuksan Island Forest. In addition, due to the vegetation succession and climate factors, one major area of potential natural vegetation species were estimated to gradually increase the distribution ratio of the Evergreen Broad-forest.

In order to understand the characteristics of Island floral resources, big trees and flora of Jismido was investigated. The observations were collected between January 29 to 30 and February 9 to 11, 2013. The Vascular plants in Jisimdo amounted to 133 taxa: 61 families, 116 species, 15 varieties, and 2 forms. Among them, pteridophytes contained 2 families and 9 species such as Osmunda japonica, Pteris multifida, Pteris cretica, Arachniodes sporadosora, Cyrtomium falcatum, Dryopteris hondoensis, Dryopteris lacera, Dryopteris nipponensis, and Asplenium incisum. Naturalized plants included a total of 8 species. Rumex crispus, Trifolium repens, Erigeron annuus and Sonchusoleraceus. Also, Korean endemic plants (Rubus longisepalus var. tozawai) were found growing around the stone wall and in the foot of the Jisimdo Trail as an individual unit. As for the flora region, there were plants specially designated by the Ministry of the Environment. One species of the Arachniodes sporadosora was identified in Grade IV, and 11 species including Litsea japonica, Stauntonia hexaphylla, Actinodaphne lancifolia, Cinnamomum japonicum, Machilus japonica and Fatsia japonica were identified in Grade III. The other 25 species including Pteris cretica, Asparagus cochinchinensis, Pittosporum tobira, Euonymus japonica, Camellia japonica, Elaeagnus macrophylla, Neolitsea sericea, Quercus acuta, Castanea cuspidata var. sieboldii, Sinomenium acutum, Machilus thunbergii, Mallotus japonicus, Aucuba japonica and Aster spathulifolius were identified in Grade I. In Jisimdo there was a total of 12 big trees which included, 2 Machilus thunbergii, 9 Pinus thunbergii, and 1 Castanea cuspidata var. sieboldii. The widest tree was the Pinus thunbergii, a 350-400 year old tree which had a trunk of 382cm in diameter. It is very rare for big trees to be collectively distributed in such a narrow island area, and this makes it worthy of preserving academically, culturally, and ecologically. It is also very necessary to conduct further research on precise individuals, individual ecology, and growth conditions. The environment of Jisimdo has an important meaning in the aspects of geography, history, culture, and biology. Thus it is urgent that we conduct a basic but precise investigation. Based on this investigation, active preservation measures can be conducted and control methods caused by the continuous increase in visitors will be established.

This study was carried out in the soil environment of the halophyte habitant in Suncheon Bay, from April 2010~ May 2011. The Halophyte community of the Suncheon Bay was classified into 10 sites: Phragmites communis community(5 sites), Carex scabrifolia community(1 sites), Bare ground(1 sites) and Suaeda japonica community(3 sites), which were a distributed zonation throughout the halophyte habitant. The pH was low in the A-1 site from April 2010 and was high in the C-1 site from November 2010, with the Value of 6.24 and 7.34, respectively. The salinity was high in the A-1 site from November 2010, low in the D-1, D-2 site from October 2010, with value of 5.20ppt and 1.7ppt. The moisture contents were high in the A-2 site from April 2010 and were low in the D-3 site from April 2010, with the value of 50.50% and 28.38%. The organic matter was high in the A-2 site from July 2010 and was low in the A-3 from November 2010, with the value of 11.35% and 3.81% respectively. The total nitrogen was highest in the A-2 site from May 2010 and lowest in the A-2 site from April 2011 with value 2.0 mg/g and 0.15mg/g. The electronic conductivity was high in the A-5 from November 2010 and was low in the D-1 site from May 2010 with the value 10700us and 3030us respectively. The soil particle size distribution in the sites showed a soil particle size(250㎛) a higher percent in June than April according to the change of season. The results of this investigation on environmental characteristics of the substratum in the halophyte habitant show that there are significant differences in halophyte community according to the properties contained in the soil of Suncheon Bay. Further, we suppose that more precise information in the halophyte habitant of Suncheon Bay will be a important data in the knowledge of the formation of soil environment.

This research was carried out from May to October 2015 to figure out the assessment class of Wando-gun``s vegetation and conservation values. According to the physiognomic classification, this area can be divided into the following 4 categories. The deciduous broad-leaved forests, evergreen coniferous fores, evergreen broad-leaved forest and herb vegetation. Based on the result of this classification, the Braun-Branquet method can categorize the plants into twenty-two different communities, such as the Carpinus turczaninowii, Pinus thunbergii, Pinus thunbergii-Eurya japonica, Castanopsis sieboldii, Machilus thunbergii, Elaeagnus macrophylla, Pittosporum thbira, Euonymus japonicus, Eurya japonica, Sageretia thea, Rosa wichuraiana, Eurya emarginata, Ligustrum quihoui, Camellia japonica, Quercus acuta, Litsea japonica, pueraria lobata, Rubus parvifolius-pueraria lobata, Miscanthus sinensis, Carex boottiana, Pteridium aquilinum, Rosa multiflora community. The grade Ⅰ area includes Bokssaengdo and galdo which are both uninhabitied islands that has a ecological nature states. Grade Ⅱ area is Janggodo and Hyeongjedo, and grede Ⅲ area is Chido, Jedo, Daemangdo, Sangdo, Huinyeodo, Sobyeongpungdo, Nangdo, and Bariseom. The islands designated as the specific islands of vegetation areas are Bokssaengdo, galdo, Janggodok, Hyeongjedo. These islands contribute to the specific geographical characteristic of the Southwesten Coast, and thus its conservation value is high.

This research traced changes in the climate and soil environment of the halophyte habitat in Suncheon Bay from April 2010 to June 2013. Soil enviornment differences of the halophyte communities in Suncheon Bay were investigated using ANOVA. The results showed that plant communities`` soil environment differed and indicated that according to the halophyte habitat the soil environment differed diversly. It was also assumed that plant habitation needed different soil environment. Moreover, if major halophyte communities and the soil environment have a significant relationship, specific changes in the soil environment induced by changes in halophyte communities can be predicted. Thus, in this sense, long-term monitoring is necessary in order to figure out the relationship between soil environment and halophyte. In addition, a regression analysis was used to identify the effects of climate on soil environment of halophyte habitat. Soil environment affected by climate were pH, OM, Sal, and EC. Sal and EC showed to be more affected by the climate(temperature, rainfall, sunshine hours, and relative humidity). The results also implied that soil environment may vary with the climate. In conclusion, the statistical analysis on environmental factors of halophyte habitat in Suncheon Bay showed that soil environment of halophyte communities was significantly correlated with climate. Thus, in order to preserve the ecosystem of coastal salt marsh, basic information on the soil environment and climate of halophyte habitat should be continuously collected in the salt marsh of Suncheon Bay.

This research was carried out from July to August 2013 to figure out the assessment class of Geoje and Changwon Kyeongnam`s vegetation and conservation values. The physiognomic classification divided the area into 5 types as follows: the deciduous broad-leaved forests, evergreen coniferous forest, evergreen broad-leaved forest, artificial afforestation and herb vegetation. According to the result of this classification using the Braun-Branquet method, plant communities can be categorized into fifteen different communities, such as the Quercus aliena, Rosa wichuraiana, Albizzia julibrissin, Pinus densiflora, Pinus thunbergii, Pinus thunbergii-Eurya japonica, Pinus densiflora-Pinus thunbergii, Elaeagnus macrophylla, Juniperus chinensis, Ailanthus altissima, Prunus sargentii, Salix gracilistyla var. purpurascens, Salix gracilistyla var. purpurascens -Pueraria thunbergiana, Pteridium aquilinum var. latiusculum, Pteridium aquilinum var. and the latiusculum-Artemisia princeps community. The natural environment in uninhabited islands has an important implication from the geographical, historical, cultural and biological aspect. Thus a systematic survey on uninhabited islands can provide us with significant information. Based on the systematic survey, management methods and preservation countermeasures should be established in line with the increase in visitors.

This study was carried out in the soil environment of halophyte habitat in Suncheon Bay, from April to June 2010. Halophyte habitat of the Suncheon Bay were classified into 10 sites: Phragmites communis community(5 sites), Carex scabrifolia community(1 sites), Bare ground(1 sites) and Suaeda japonica community(3 sites) which were distributed zonations thoughout the halophyte habitat. The soil environment(pH: 6.24-6.95, salinity: 2.9-1.7 ppt, moisture content : 50.50-28.38 % and organic matter content :9.74-7.46 %) of Suncheon Bay was typical characteristics of the estuary marsh. The soil`s particle size distribution in those sites showed soil particle size(1,000 ㎛) in June, which is higher number than that of April due to the change of season. The results of this investigation on environmental characteristics of the substratum in the halophyte habitat show that according to the properties contained in the soil of Suncheon Bay there are significant differences in halophyte community. Further, we suppose that more precise information on the halophyte habitat of Suncheon Bay is of primary importance in gathering knowledge on the formation of soil environment.
