The flora and vegetation of Jindo Archipelago were investigated from 1985 to 1989. In the area, 1089 species, 3 subspecies, 133 varieties, and 22 forma of vascular plants were recovered. From the data, the ecological characteristics such a value 1.39 in Pte-Q and Ch-$D_1-R_3$-e in biological type were recognized. Vegetation of the area is classified into 8 communities: Pinus thunbergii-, Quercus serrata-, Q. variabilis-, Carpinus coreana-, Prunus sargentii-, Camellia japonica-, Castanopsis cuspidata var. sieboldii and Q. acuta-community. The actual vegetation map was conducted with the materials obtained by the investigation of the vegetation in 103 area.

This study tried to analyze error range and resolution of drone images using a rotary wing by comparing them with field measurement results and to analyze stands patterns in actual vegetation map preparation by comparing drone images with aerial images provided by National Geographic Information Institute of Korea. A total of 11 ground control points (GCPs) were selected in the area, and coordinates of the points were identified. In the analysis of aerial images taken by a drone, error per pixel was analyzed to be 0.284 cm. Also, digital elevation model (DEM), digital surface model (DSM), and orthomosaic image were abstracted. When drone images were comparatively analyzed with coordinates of ground control points (GCPs), root mean square error (RMSE) was analyzed as 2.36, 1.37, and 5.15 m in the direction of X, Y, and Z. Because of this error, there were some differences in locations between images edited after field measurement and images edited without field measurement. Also, drone images taken in the stream and the forest and 51 and 25 cm resolution aerial images provided by the National Geographic Information Institute of Korea were compared to identify stands patterns. To have a standard to classify polygons according to each aerial image, image analysis software (eCognition) was used. As a result, it was analyzed that drone images made more precise polygons than 51 and 25 cm resolution images provided by the National Geographic Information Institute of Korea. Therefore, if we utilize drones appropriately according to characteristics of subject, we can have advantages in vegetation change survey and general monitoring survey as it can acquire detailed information and can take images continuously.

본 연구는 태안해안국립공원에 분포하는 식생 현황 및 공간분포 특성을 분석한 후 그 결과를 바탕으로 식생 관리 방안을 제시하기 위해 실시하였다. 분석 결과, 태안해안국립공원에서 확인된 식물군락은 산지 상록활엽수림인 동백 나무군락, 산지 낙엽활엽수림인 소사나무군락, 소사나무 - 곰솔군락, 음나무군락 및 모감주나무군락, 산지침엽수림인 곰솔군락, 곰솔 - 소나무군락 및 소나무군락, 저층습원식생인 갈대군락, 해안사구식생인 순비기나무군락, 갯그령군락, 갯쇠보리군락, 통보리사초군락 및 갯잔디군락, 염습지식생인 해홍나물군락, 식재림인 아까시나무군락이었다. 현존식생도에 나타난 경관유형은 곰솔군락 (3.92%), 소나무군락 (1.40%), 아까시나무군락 (0.05%), 사구식생 (0.11%), 경작지 (0.46%), 해변 (0.24%), 간벌지역 (0.08%), 나지 (0.16%), 바다 (93.58%) 등이었다. 식생유형에서는 곰솔군락이 $14.797km^2$ (3.92%)로 가장 넓은 면적을 차지하였다. 인간 간섭과 이용의 정도에 따라 해안과 내륙에 분포하는 곰솔 군락은 층위구조와 종 조성이 다르게 나타났으며, 교란 빈도가 낮은 지역에서는 떡갈나무 및 졸참나무가 잠재적 식생을 형성하여 천이가 진행되고 있는 것으로 판단된다. 해안에 분포하는 곰솔군락 하층에는 붉은서나물이, 기지포와 삼봉사구에는 갯그령군락과 통보리사초군락이 우점하고 있으며, 그곳을 중심으로 백령풀이 침입하여 넓게 분포하고 있다. 외래식물인 붉은서나물과 백령풀은 확산속도가 빠르게 나타나고 있어 해안식생에 부정적인 영향을 미칠 것으로 판단되며, 이에 대한 모니터링 및 관리방안이 요구된다.

The number of species and forest area has decreased as urbanization is progressed. The landscape degradation was examined by analyzing vegetation map, satellite image and characteristics of actual vegetation. The study was conducted in Mt. Baekja and its surroundings located on Gyeongsan city, southeastern Korea. As the result of landscape analysis, agricultural field was a characteristic attribute of the study area. Lowlands of this study area were occupied by agricultural field and various plantations. For 15 years from 1987 to 2002, forest area decreased from 2,072.9 ha to 1,853.2 ha, and shape index and fractal dimension of vegetation patches increased from 1.32 to 1.65 and from 1.05 to 1.09, respectively. Pinus densiflora Siebold & Zucco. community showed the highest species diversity, whereas Larix kaempferi (Lamb.) Carriere community showed the lowest species abundance. As forest management implications, monitoring of endangered plant species (Jeffersonia dubia (Maxim.) Benth. & Hook.f. ex Baker & S.Moore), and restoration of lowland forest from plantation to natural forest were discussed. Further, establishment of greenways utilizing existing streams, roadside, and public facilities were recommended.

황구지천과 청미천의 본류와 폐천에서 하도형태, 식물상 및 식생분포 특성을 분석하였다. 항공사진과 옛 지형도를 분석한 결과, 폐천은 제방축조에 의해 사행하도가 단절되어 형성된 것으로 나타났다. 전체 식물종수와 귀화식물 백분율은 본류가 폐천에 비해 높았다. 두 폐천에서 수생, 습생식물 종수의 백분율은 각각의 본류에서 보다 높았다. 주성분분석결과 폐천과 본류 사이의 식물상 구조는 황구지천이 청미천에 비해 비교적 유사하게 나타났다. 두 폐천에서 수생, 습생 식물 분포 면적비율은 각각의 본류에 비해 높았다. 두 폐천에서 우점식물은 정수식물인 줄이었다. 따라서 폐천의 식물상과 식생분포는 습생, 정수 생태계의 특성을 나타내었으며 경관수준에서 다양성을 제공하였다.

This study constructed a high-resolution bioclimatic classification map of South Korea which classifies land into homogeneous zones by similar environment properties using advanced statistical techniques compared to existing ecological area classification studies. The climate data provided by WorldClim(1960-1990) were used to generate 27 bioclimatic variables affecting biological habitats, and key environmental variables were derived from Correlation Analysis and Principal Component Analysis. Clustering Analysis was performed using the ISODATA method to construct a 30'(~1km) resolution bioclimatic classification map. South Korea was divided into 21 regions and the results of classification were verified by correlation analysis with the Gross Primary Production(GPP), Actual Vegetation map made by the Ministry of Environment. Each zones' were described and named by its environmental characteristics and major vegetation distribution. This study could provide useful spatial frameworks to support ecosystem research, monitoring and policy decisions.

This study is to offer the basic information and materials for the restoration of the urban forest and the ecologically healthy and continuous green belt through the investigation and the analysis on the vegetation in Hwasan Park, Chonju-City. The flora of Hwasan Neighborhood park was composed of 86 families 230 genera, 261 species, 35 varieties, 1 formae or 298 Taxa. Among them, calculation of Pte-Q Index represented 0.60, Fisher's Index. Some characteristics of the plants in this area have represented such as Th-D1-R5 type in biological type, erect form(64.6%) in growth type, 30 taxa in naturalized plants. The life form spectra investigated from Hwasan neighborhood park was recognized as the following M"17.4%, N:11.4%, E:0.3%, Ch:0%, H:29.8%, G:6.7%, HH:0%, Th:34.2%. By the Z-M method 5 plant communities and 3 afforestation were recognized; Quercus variabilis community, Q.acutissima community, Q.serrata community, Sorbus alnifolia community, Pinus densiflora community, P.rigida afforestation, Robinia pseudo-acacia afforestation and Larix leptolepis afforestation. The actual vegetation map constructed on the grounds of the communities classified and other data. The pattern of successional trend of tree species might be suggested: L. leptoleipis, P. rigida and P. densifloralongrightarrowQ.variabilis and Q.acutissimalongrightarrowS.alnifolia and Q.serratalongrightarrowCarpinus tschonoskii community. Three measurements of species diversity (richness index(SR), Shannon-Wiener index(H'), evenness index(J')) and their relationship with community type were studied in the surveyed plant communities. Q.serrata community was higher in SR, H', J' than the other communities, whereas R.pseduo-acacia afforestation was low. Finally, The vegetation of the Hwasan neighborhood park must not allowed any more. Nothing ca be better than native states in preserving the ecosystems.tems.

Mountains have been playing an important role in the Japanese culture. It is important from landscape planning perspectives to maintain mountains in the proximity of cities. In this thesis, the geographical perception of residents in Kohoku New Town has been studied. Geographical changes before and after the Kohoku New Town development were clarified first. Following these clarifications, interviews with residents who moved into the area before and after the development were conducted. In this investigation, the interviewees were asked about mountains, valleys, hills, and slopes; and the areas that they recognize on the map were then specified. From these results, the mountain area which residents recognize and the actual geographical features were compared. The geographical characteristics of the mountains that the residents recognize were revealed, and the perception of mountains was defined. Not only did geographical features and vegetation affect the perception of mountains, but also residents' personal experiences were important. As a result, new information for future geographical landscape planning has been obtained.
