오늘날 지속가능한 발전의 주요 목적으로서 환경의 효과적 보호와 신중한 자연자원의 이용이 강조된다. 이와 같은 목적들을 성취하기 위해서 종합적인 경관 정보가 필수적이다. 한국의 경우, 도시화는 전통적인 농촌 경관 변화, 산림 손실과 단편화 등 많은 환경 문제를 야기했다. 특히 산림이 높은 생물 다양성 가치를 갖고 있는 한국으로서는 산림 손실과 단편화는 생태관점에서 보면 아주 치명적이다. 현재 개인 또는 공공 부분 개발 프로젝트를 위한 환경 영향 평가의 일부분으로 시각 경관 영향 평가가 요구된다. 그러나 이런 시각 경관 영향 평가는 단지 전체 경관의 일부분의 경관 정보만을 제공하고, 특히 현재 경관 평가에서는 경관의 생물 다양성 가치를 평가하지 않는다. 본 연구는 이와 같은 문제점들을 극복하고 한국 상황에 맞는 지속가능한 경관 계획을 위한 필수적인 종합 경관 정보를 제공하기 위해서, 경관 특성과 생물 다양성 가치 평가를 위한 생태 이질성 지수를 결합한 진보된 경관 특성 평가 방법론을 제시하는데 그 목적이 있다. 이 방법론을 통해 경관 특성 평가에서 12가지 경관 특성 유형(type)을 분류하였고 그것의 분포, 경관 특성적 형태, 경관 특성에 부정적인 영향을 줄 수 있는 개발 압력 등을 분석하고 서술하였다. 분석 결과, 주택과 산업 단지 개발, 농지 형질 패턴 변경, 수변 공간 개발 등이 주요 개발 압력으로 나타났다. 경관 생태 이질성 평가 결과에서는 도시근교 지역과 농촌 경관 특성 유형 지역에서 잠재적 생물 다양성 가치가 높았다. 산림 지역 경관 특성 유형에서는 잠재적 생물 다양성 가치가 중간 수치로 나온 반면 도시 경관 특성 유형에서의 잠재적 생물 다양성 가치는 아주 낮았다. 비록 제한된 데이터와 경관 생태 이질성 지수 사용으로 인한 문제점들(스케일 종속적, 변화 패턴이 예측하기 힘든 지수, 자의적인 분류시 다른 결과 발생, 더 종합적인 생물 다양성 잠재력을 평가하기 위해서는 더 많은 다른 경관 생태 지수 필요 등)이 제기되었지만, 이 연구에서 제시된 진보된 경관 특성 평가 방법론을 통해 얻은 종합적인 경관 정보가 지속가능한 경관계획을 할 때 어떻게 잘 활용되어질 수 있는지 예로써 증명하였다. 그 결과 진보된 경관 특성 평가 방법론이 지속가능한 경관 계획을 위한 수단으로 사용될 수 있을 것으로 사료된다.

경관생태지수는 녹지의 이질성(Heterogeneity)을 계량화하기 위하여 제안되고 발전되어 왔다. 지난 수십년간 많은 연구에서 경관생태지수가 광범위하게 사용되어 그 효용성이 인정되었지만, 경관생태지수의 사용에 따른 많은 문제점들이 제기되고 있다. 본 연구의 목적은 경관생태지수 사용에 따른 고려사항과 문제점들을 기존 연구들을 통해 고찰하고, 이를 기초로 적절한 응용방법을 제안하고자 하는 것으로, 지수의 문제점을 내재적인 문제들과 응용상의 문제들로 구분하여 논의하였다. 지수 자체의 내재적인 문제로는 녹지구조와 기능과의 관계, 녹지구조의 측정 및 대표, 그리고 지수들의 불안정성 등을 들 수 있으며, 응용상의 문제점들로는 지수 선택, 스케일 변화와 피복 분류과정에 개입된 문제, 해석상의 오류 등을 들 수 있다. 이러한 문제들을 최소화하는 방안으로는 첫째, 가설에 입각한 연구가 필요하며, 둘째, 측정하고자 하는 녹지의 공간적 특성을 명확히 규정하여야 하고, 셋째, 변위가 예측 가능한 지수를 사용해야 하고, 넷째, GIS나 인공위성 자료의 축척을 변화시키지 말아야 하며, 마지막으로 다섯째, 피복분류 알고리즘을 사용하여 분류상 오류를 최소화해야 한다는 점이다.

Landscape change is the modification and replacement of landscape elements in accordance with human management and natural disturbance on land mosaics. During landscape change, changes in patterns such as heterogeneity, diversity and shape, and juxtaposition of spatial elements are also accompanied. For the sustainable landscape system, therefore, spatial characteristics of the landscape should be considered in implementation of landscape conservation and restoration planning. Short-term changes of land-use and landscape pattern during the 10 years of 1980s and 1990s were investigated in the agriculture-forestry dominated landscape system through the statistics and the analysis of landscape-vegetation map. Study area is Yangdong-myon, Yangpyung-gun (37°27′30"N, 127°46′50"E), Kyonggi-do, in central Korea. Landscape change of this region was significantly related to the recent industrialization according to socio-economic development. Analyses of landscape pattern show that the area of secondary forest sustained by human activity decreased and it was replaced with large exotic plantations during this period. Area of paddy field was also extended. Fractal dimension of the total landscape increased, but that of paddy field area decreased due to rearrangement for mechanized farming. Moreover, the area of landscape management regimes such as plantation and cultivation increased in land mosaics during this period.

The purpose of this thesis is to suggest objective basic data for the environmental design through the quantitative analysis of the visual quality included in the physical environment of forest landscape. For this, landscape values of forest landscape have been evaluated by using the Iverson method, the images structure of forest landscape's main utilizing space have been analysed by the factor analysis algorithm, degree of visual preferences have been pleasured mainly by questionnaries and SBE method, and finally these thesis can be summarized as fallow LCP with high values of Iverson factors I and IV yield high landscape value. Specifically, Iverson factor IV has been found to play the dominant. For all experimental points, significant seasonal variations in S.D. scale values have been observed. In natural parks, where artificial structures are complementary to the natural landscape, main factors of image are S.D. scales such as the visual sequence, the formal simplicity of structures, the emphasis, the unification of heterogeneous factors and the assimilation. Factors covering the spatial image of natural parks have been found to be the overall evaluation, the individual characteristics, the tidiness, the potentiality, the dignity, the intimacy and the space volume. For all seasons, factors such as the individual characteristics, the dignity, the tidiness, the potentiality, yield high factor scores. As for factors determining the degree of visual preference, variables such as the summit, the skyline, rocks, the water and the degree of natural destruction by artificial structures yield high values for all seasons.

We have investigated microclimatic controls on the spatiotemporal variations of net primary production (NPP) of a rugged forested watershed using the process-based biogeochemical model (BIOME-BGC). To validate the model simulation of water and carbon cycles at the plot scale, we have conducted field survey over deciduous broadleaf forest (DBF) and evergreen needleleaf forest (ENF) since 2000. The modeled values of soil temperature, soil moisture and soil respiration showed high correlation with those from the field measurements. The modeled seasonal changes of NPP showed high correlation with air temperature but no significant correlation with water related parameters. The precipitation frequency turned out to be the best climatic factor to explain the annual variation of NPP. Furthermore, NPP of ENF was more sensitive to precipitation frequency than that of DBF. With changes in vegetation cover and topography, the spatial distribution of NPP was of great heterogeneity, which was negatively correlated with the magnitude of NPP. Despite the annual precipitation of 1,400mm, NPP at the study site was constrained by the amount of water available for the vegetation. Such a modeling result should be verified by the field measurements.

The purpose of this study is to classify, evaluate and grade the existing highway tunnels to increase landscape and natural statistics keeping the structural safety about tunnel gates area and induce the ones that will be constructed in the future by drawing the improvements and restoring the techniques as an environment-friendly. To examine the types of tunnel gate area, total 54 tunnels were investigated by selecting Gyeongbu Expressway, Yeongdong Expressway, and Jungang Expressway. Tunnel entrances and exit ports were classified as a Wall-closed type and Protruding type, which is based on tunnel gate type. Vegetation Landscape types were classified as Multilayer-Same as the surrounding landscape_(MS), Multilayer-Difference of surrounding landscape_(MD), Single layer-Same as the surrounding landscape_(SS), Single layer-Difference of surrounding landscape_(SD), and a Desolate type which based on vegetation layers and environment-friendly. Potential vegetation recovery was identified based on the structural stability and revegetation potential of the tunnel. The factors include the structural stability of the slope height and slope gradient were selected. Revegetation potential was identified as a growth potential. This factor was used in the step to classify vegetation recovery potential of a tunnel. The result, which investigated the types of tunnel entrances and exit parts has found that the most typical in 33 places was a Wall closed type with 61.1% of the total ones. The case of vegetation landscape types was created but different from the ones surrounding it with 85.2% of the total ones. It is judged that the currently constructed vegetation of tunnel entrance and exit parts had put convenience on the safety and management before landscape consideration. In addition, tunnel entrance and exit parts with excellent potential for vegetation recovery were all Protruding type. In addition, it is judged that slope stability can easily obtain growth. Therefore, entrance and exist of the highway tunnels, which will be constructed in the future, should reflect location and the result of the natural and ecological survey in design by performing it in advance and their types, which minimize the damage area range, should be applied to the local characteristics suitably. In addition, the ecologically healthy tunnel construction should be done by introducing active vegetation recovery techniques based on its safety.

This study was carried out investigation of characteristics palace gardens representing historical background, political and cultural identity in Korea, China, and Japan. It had been done a comparative analysis in formation, location and site layout, site composition, landscape elements and planning, landscape technique and vista for palace gardens in East asia's three countries. In order to process this study, Changdeokgung Palace in Korea, Summer Palace in China and Sento Imperial Palace in Japan were selected based on similar status. therefore it provide theoretical foundation to investigate the identity of palace gardens in three countries. Furthermore the study determined homogeneity(similarity) and heterogeneity(differentiation) of the characteristics between palace gardens in three countries through the in-depth comparative analysis in order to investigate identity of palace gardens in three countries and to present the value of Korean palace garden. Homogeneity and heterogeneity between palace gardens in three countries deducted from the study were summarized as follows; First, it shows indigenous style of Korean garden throughout adapting natural terrain without natural destruction. Second, various symbolic elements which ie reflected East asian ideologies present in the gardens. Chinese thoughts and technique were influenced in the development of palace garden in Korea and implemented in similar ways of China. Homogeneity of utilizing waterscape could be found in three countries. Lastly, Palace garden in Changdeokgung had played a role as cultural place with taste for the arts rather than representing authority of the throne. It appears to be similar in China and Japan. The reason how Korea, China and Japan established their own independent style is that each palace garden had been developed to embrace indigenous culture with introduced elements even though they were closely bound up with culture.

The purpose of this study is to test the applicability of landscape metrics for quantifying and monitoring the landscape structure in the Geumho River watershed, which has undergone heavy environmental disturbances. Landscape metrics were computed from land cover maps(1985, 1999) for the forest patches. The number of variables were reduced from 12 metrics to 3 factors through factor analysis. These factors accounted for above 91% of the variation in the original metrics. We also determined the relative effects of land development on the changes of forest landscape structure using multiple linear regression analysis. At the forest patches, the conversion of forest to urban areas and agriculture resulted in increased fragmentation. Patch area and patch size decreased. and patch density increased as a result of the conversion of forest to agriculture($R^2=0.696$, p<0.01). The heterogeneity of patch size and complexity of patch shape mainly decreased as a result of the conversion of forest to urban areas($R^2=0.405$, p<0.01). The density of core area and edge showed the tendency increase, but there was no relationship with the conversion of forest to urban area and agriculture The future research will be needed to analyze correlations between landscape structures and specific environmental and socioeconomic landscape functions.
