The purpose of this study is to analyze of biotope types and to develop assessment for forest ecosystem evaluation method. Vegetation types divided into 27 types. Considering the vegetation types, vegetation structures, DBH, potentials, and disturbance, it was decided to apply 58 biotope types and survey site's biotopes were divided into 24 biotope types. Assessment indicators were naturaliness, diversity, rarity, stability, potential, and disturbance. The areas given the first grade in ecological value included 9.2% of the site's total land. Areas with the second grade accounted for 43.0% of the total land. Areas with the third grade made up 47.8% of the site and mostly they were areas with dominance of fired area and artificial forest. To plan to build naturally-development for Site, there should be plans to conserve areas with the first grades. For the areas with the second, and third grades, plans for ecological land use based on conservation and restoration in terms of securing biodiversity are needed.

The purpose of the study is to identify land use characteristics which have influence on residents' mental health. Land use and housing types indicators including green areas and parks were selected by analyzing the related environment and health researches. Research database for every variable from 33 neighborhoods in Jeonju city were established through National Health Insurance Corporation, where is available for getting mental and behavioral disabilities (F code) expenses. The relation between those indexes and mental health were analysed. The findings of this study are as follows : First, the higher price area like apartments and raw houses the residents lived in, the more expenditure of F-code was paid. It could be interpreted by the relatively high frequency of medical treatment and interests on the health. Second, the more green area except park were there, the more F-code expenditure was given, which could be explicated with the spatial co-relation between location of green area and apartments of Jeonju city. It was very high, and apartment element's affect on the F-code was much more than the green zone. Third, the nearer to park were the residents, the less F-code expenses was paid.

The city's countryside is adjusting to change by urbanization. The recent changes in rural landuse and damages of local landscape characteristics are very serious. But, few studies address the relationship between land-use and quality of landscape for these area. The aim of this study is to clarify causes and problems of the change through investigating changes of landscape as a function of land-use. The results are as follows 1) The change of landscape can be seen as a functional of land-use. Landscapes are characterized by changes of regional environments. These are the urban-rural fringe area which need special consideration for urban development and also for rural landscape quality. 2) 11 types of landscape patterns are found for landscape management. these are Regional commercial area, Apartment development, Recreation & seisure, Golfs, Housing complex, Industrial complex, Vinyl house, Rural village, Evaded facilities, Rivers, Cultural heritages. These landscape types are explained as 'stimuli-responses model'in Bryant's Forces of urbanization. 3) The policy implications of these study are as follows : First is the necessity of landscape management in Grown Management Zone and Natural Reserved Zone in the Metropolitan level, Second is the necessity of development control in semi- agricultural area. The last is the necessary of long range management plan in the urban-rural fringe area.

In spite of importance of the farm area in the city, the urbanization and industrialization strongly results in decrease of the farm area. The purpose of this study is to establish an effective way of agricultural land uses by examining on the intention of the farmers based on the survey in Seoul area. The areas, the agricultural types, the landowner's ages, and farm land sizes, were surveyed and analyzed with respect to urban agricultural planning and land use planning. All the collected data were basically analyzed with Contingency Table and Chi-square Test using SAS statistical package. The structures of the intention of agricultural land uses were understood with the comparative analyses of the agricultural land owners, the agricultural land leaseholders, the areas, landowner's ages, farming types, and so on.

this study was focused on the effects of fire on spatial change of vegetation landscape in rural region. Fire types recognized as erown fire, severe surface fire and light surface fire in order of increasing intensity were described in a fire map. GIS was introduced to understand the relationship between fire types and topographic conditions or vegetation types. We also investigated land-use type and regeneration strategies after burning. Fire intensity depended on topographic conditions and vegetation types. Special land-use type in this area was collection of edible mushroom (Tricholoma matsutake). Mushrooms had been obtained from Pinus densiflora forests existing as edaphic climax or managed artificially. Regeneration strategy in burned areas was to make sprouts from burned oak stumps. A higher density and growth rate of sprouts, as compared to those on unburned areas, facilitated vegetation succession from P. densiflora forest to oak forest and consequently led to change of landscape pattern.

Soil seed banks as natural storage of plant seeds play an important role in the maintenance and regeneration of watershed. Natural regeneration potential of the soil seed bank of Land use types (LUTs) in Ogun River watershed (ORW) was investigated. ORW was stratified using proportionate sampling technique into Guinea Savannah (GS), Rainforest (RF) and Swamp Forest (SF) Ecological Zones (EZs). Three LUTs: Natural Forest (NF), Disturbed Forest (DF) and Farmland (FL) were purposively selected in GS: GSNF, GSDF, GSFL; RF: RFNF, RFDF, RFFL and SF: SFNF, SFDF, SFFL, respectively. Systematic line transects was used in the laying of the sample plots. Sample plots of 25 m×25 m were established in alternate positions. Ten 1 m×1 m quadrats were randomly laid for soil core sampling from previously randomly selected ten plots. The core samples (10) were pooled per plot in each LUT and placed in individual trays. Ten trays with sterilized soil were used as control. The trays were watered regularly and checked for seedlings emergence fortnightly for 18 months. The experimental design used was 3×3 factorial experiments. ANOVA, Diversity index (H') and Similarity index (SI) were used to analyze the data. There was significant difference in seedling emergence among ecological zones and land use types (p<0.05). A total of 4,400 seedlings emerged from the soil samples. All species were distributed among 32 families. FL in the RF had the highest number of germinated seeds (705±37.33 seedlings) followed by DF in the RF (701±49.6 seedlings). The lowest emergence was in NF of the SF (199±28.41 seedlings). DF in the RF had highest number of species (34) distributed among 22 families. Emergence from soil seed bank of NF in ORW was generally with more of tree species than herbs that were predominant in FL and DF.

The increase of the solar reradiation from urban areas relative to suburban due to urbanization heats up the air temperature in urban areas and this is called the urban heat island (UHI) effect. This UHI effect has a positive relationship with the degree of urbanization. Through the studies on UHI using the satellite imagery, the effect of the surface heat radiation was observed by verifying the relationship between the air temperature and the land cover types (surface materials such as urban, vegetation, etc.). In this study, however, the surface temperature distribution was studied in terms of land use types for Seoul. Using land use types, the surface temperature in urban areas such as residential, industrial, and commercial areas in Yeongdeungpo, highly packed with industrial and residential buildings, was maximum $6^{\circ}C$ higher than in the bare ground, which indicated that the surface temperature reflected the pattern of the human-consumed energy on the areas and showed that one of the important causes influencing the air temperature except the surface heat reradiation by the sun is the anthropogenic heat. Also, the effect due to the restoration of the Chunggae stream on UHI was investigated. The average surface temperature for the Chunggae stream was reduced about $0.4^{\circ}C$ after restoration. Considering that each satellite image pixel includes mixture of several materials such as concrete and asphalt, the average surface temperature might be much lower locally reducing UHI near the stream.

This study was conducted to predict future land-cover changes under climate change scenarios and to cluster analysis of regional land-cover characteristics. To simulate the future land-cover according to climate change scenarios - A1B, A2, and B1 of the Special Report on Emissions Scenarios (SRES), Dyna-CLUE (Conversion of Land Use Change and its Effects) was applied for modeling of competition among land-use types in relation with socioeconomic and biophysical driving factors. Gyeonggi-do were selected as study areas. The simulation results from 2010 to 2040 suggested future land-cover changes under the scenario conditions. All scenarios resulted in a gradual decrease in paddy area, while upland area continuously increased. A1B scenario showed the highest increase in built-up area, but all scenarios showed only slight changes in forest area. As a result of cluster analysis with the land-cover component scores, 31 si/gun in Gyeonggi-do were classified into three clusters. This approach is expected to be useful for evaluating and simulating land-use changes in relation to development constraints and scenarios. The results could be used as fundamental basis for providing policy direction by considering regional land-cover characteristics.

본 연구는 기존 연구에서 수행된 전국 단위의 정량적 산지면적 변화량을 공간적으로 배분하여 광역시도별 산지면적 변화를 추정함으로써 지역산림계획의 수립을 지원하기 위해 수행되었다. 토지를 산지, 농지, 도시 및 기타지로 구분하고 토지이용 형태별 변화 여부를 종속변수로, 지형요소, 이용 제한요소, 사회·경제적 요소, 개발 인프라를 독립변수로 하는 로지스틱 회귀모형을 개발하였다. 우리나라 전체를 30m×30m 격자로 분할하여 각 Cell에 해당하는 독립변수 자료를 구축하였고, 로지스틱 회귀모형을 이용하여 각 토지이용 형태가 타 유형으로 변화하는 확률을 추정하였다. 추정된 토지이용 변화확률을 기반으로 변화순위 지도를 구축하였고, 연도별 토지이용 변화량을 변화순위에 따라 순차적으로 배분함으로써 토지이용 변화의 공간적인 변화를 분석할 수 있었다. 경사도와 지자체별 개발 가능한 경사도 기준이 산지가 도시 및 기타지로 변화될 확률에 가장 큰 영향을 미쳤으며, 경사도와 개발 가능한 경사도 기준이 낮을수록, 토지가격과 인구밀도가 높을수록 산지가 도시 및 기타지로 변화될 확률이 높아졌다. 그 결과 2027년까지 수도권과 대도시의 산지가 도시 및 기타지로 변화하여 산지면적이 크게 감소하였다. 그러나 2028년 이후 2050년까지 서울, 경기, 제주를 제외한 대부분의 지역에서 산지면적이 빠르게 증가하는 것으로 예측되었는데, 이는 지방 소도시의 급격한 인구감소에 기인하는 것으로 분석되었다. 이에 중앙정부에서는 변화하는 산지면적에 대응하기 위해 산지관리 정책의 전환이 필요하고, 지자체 단위에서는 인구의 감소 정책과 그에 따른 산지를 포함한 토지의 효율적 보전 및 이용체계를 수립하는 것이 필요할 것으로 사료된다.
