The purpose of this study is to classify the cities on sustainability assessment score studied in advance using cluster analysis, to present efficient management and policy direction based on analysis of sustainability index in 45 cities of all over Gyeongsangnam and Gyeongsangbuk-do. According to the results of cluster analysis, 45 cities were classed into 4 clusters by "livable-welfare city", "environmental -ecological city", "scientific-technological city", and "industrial-economic city". The livable-welfare cities must keep superior environmental sustainability, promote small and medium sized business on regional characteristic. The environmental-ecological cities have to change agriculture into future environmental industry such as ecotourism, bio-industry and landscape agriculture. The scientific-technological cities are going to need support of government scale such as income enlargement of citizen and stable job security. Finally, the industrial-economic cities must increase environmental management plants and improve quality of life through securing green spaces, maintaining public peace and applying UIS because of low quality of environment and life.

With the launch of a new millenium of the 21st century ahead, one of tasks that need to be considered in urban ecological aspect is the understanding of impact of continuing urbanization on urban ecosystem, habitats, and various species of animals and plants. In addition, alternatives and measures to mitigate these impacts including environment restoration should be pursued. In this article, the following points will be reviewed; 1) the definition and significance of an eco-city and "ecological network", 2) the necessity of an eco-network as one of factors composing an eco-city, in the aspects of urban planning and urban ecology, 3) ways to build an urban ecological network and example of foreign countries, 4) as an example of a city in Korea, the present state and impending tasks of the ecological network of Seoul city, and 5) a brief conclusion and suggestion. By providing a basic tool called "an ecological network" for urban space planning, it attempts to contribute in promoting networking of cities (netropolis) and urban biodiversity. It is believed that how to create an ecological network in an artificially developed urban area is a pending issue we are faced with. Herein lies the necessity of natural environment restoration and creation based on the so-called the Third Ecology. Regarding the efforts to return the Nature to urban citizens, there is a need to view the development of a desirable urban ecological network as the starting point and finishing point of the effort. In this way, it is believed that the objectives of urban sustainability through netropolis development would also be achieved.

As we have come to realize the problems caused by the modern civilization as well as the importance of the preservation of nature. Ecological building and urban design come to attract more attention. Therefore, the object of this study is providing the design factors and improving the design methods for the developments of ecological housing complex, harmonious with environment. Followings are the results of this study: 1. We need to turn to new trend-Ecological architecture which enables the co-exitence of nature and human being to come over the presence and face new decades. 2. Ecological architecture is based on energy-saving system and give people a healty and comfortable atmosphere. 3. In the city area, the house development should be undertaken to minimize the environmental problem through extremely high ehhiciency and technonogy. 4. We need a new development to preserve natural environment in the suburvan and small or medium city. 5. We have to develope the approach method, which is to maintain the frame of present ecological environment, to be in sympathy with geomorphology, to use the natural material in the rural community.

It is certain that urbanization has transformed the ecological consequences severely, but urban ecosystem is not fully understood yet. Urban growth is not like a static form and it spreads spatially and temporally. Therefore in studying urban ecosystem, it is important to relate the spatial pattern of urbanization to ecological processes. Using gradient analysis, we attempted to quantify the urbanization's spatial impacts in Daejeon-city and Cheonan-city, Chungcheong-province, Korea. Because of Multifunctional Administrative City Planning (MACP), a lot of development projects are planned in Chungcheong-province, Korea. It's important to study about original cities' patterns and impacts. These results can be adopted to future city planning. So several measures such as fragmentation, vegetation index, surface temperature, population density, and income rate were computed along a 75km long and 3km wide transect. The results showed that Daejeon-city has a wider urban center, lower vegetation indexes, and higher surface temperature than Cheonan-city. Therefore in the perspective of urban environments and sustainable urbanism, it seems that Cheonan-city is better than Daejeon-city. The changes along the transect have important ecological implications, and quantifying the urbanization gradient is an important step in understanding urban ecology.

The study area investigated in this research is Hwaseong city, Gyeonggi-Do where small scale development is currently in progress. For the last three years, we carried out the environmental and ecological assessment by using data from The Ministry of Environment and Han River Basin Environmental Office. Most of development works in Hwaseong city, Gyeonggi-Do are small scale developments which are related with factory and distribution complex based on individual laws and regulations. However, environmental and ecological assessment is not being sufficiently reflected beforehand. Especially, because the development takes place mainly in the outskirts of the city, the fine forest is continuously being damaged. We analyzed changes in green zone area caused by the developments. As a result, the percentage of original green zone was decreasing while the percentage of artificial green zone was increasing. We should maintain the percentage of the original green zone in order to conserve natural environment. In the past three years, the damage of the DGN (Degree of Green Naturality) 7 area that has high conservative value was little, but, there was serious damage in the area of DGN 6. In order to conserve natural environment, political and institutional investigation should be seriously carried out for mitigation of environmental and ecological damages.

개발 과정에서 발생하는 생태공간의 단절과 파편화는 생물다양성의 위협 요소이다. 특히 개발 압력이 높은 도심은 생태공간이 부족하여 연결성이 매우 낮을 것이다. 이러한 문제는 대도시에서 더욱 두드러지게 나타나는 경향이 있다. 이를 해결하기 위해 개별 사업이나 도시관리 수준에서 생태적 연결성 현황을 파악하고 개선하는 지속적인 노력이 필요하다. 그러나 대도시의 생태적 연결성 현황 파악과 개선에 대한 논의가 부족한 실정이다. 따라서 본 연구는 우리나라 대도시 서울, 부산, 대구, 인천, 광주, 대전, 울산의 도심이 가진 생태적 연결성을 평가하였다. 평가 결과 도심은 외곽이나 도시 전체와 비교해 연결성이 낮았다. 그리고 종분포모델 등 지역 특성을 반영하여 대전을 대상으로 수행한 생태적 연결망을 분석하여 1ha 이상 산림을 이어주는 최적 경로 510개를 도출하였다. 본 연구는 도시의 생태적 연결성 개선 목표 제시에 필요한 정량적 수치와 생물다양성을 포함한 지역 특성에 따른 연결망을 도출한 사례로서 의미가 있다. 환경영향평가나 도시관리에서 생태적 연결성을 개선하는 방향을 제시하고 평가 체계를 구축하는 데 결과를 활용할 수 있을 것으로 기대된다.

The typical natural landscapes and temporal- spatial regulation of Land use change and their ecological effects at Hailun County were conducted and analyzed, based on the translated data from remote sensing images in 1986, 1996 and 2000 using GIS and landscape ecological theory. The results indicated the area of arable land, paddy field and city land increased 7,786.39 $hm^2$, 3391.18 $hm^2$ and 120.84 $hm^2$ while the area of forestry, grassland and marsh decreased 3,184.88 $hm^2$, 1,625.8 $hm^2$ and 3,994.85 $hm^2$ respectively during 14 years. Dry land is a main landscape in this area. These changes made the environmental quality worse gradually, such as land degradation, soil erosion and water and soil losses, and temperature getting warmer. This study is very important for the local ecological environment protect and agricultural sustainability and land resources sustainable using.

The purpose of this study was to compare the differences of the ecological attributes in the two types of urban park at Suwon and Goyang city. 'Directly linked park' is forests and rivers in the vicinity, it is capable of re-supply of the species and 'Isolated park' is forests and rivers apart, it is a difficult re-supply of the species. The result of assessment of the ecological attributes in the two types of urban park was analyzed as the percentage of 'Forest zone' was high, but the percentage of 'Area of permeable pavement' and 'Bush area' was low. 'The planting structure' was mostly 1-layer structure(47%) and 'Foreign tree species' is high by half the proportion. 'Age classes' were a 2-3age classes level, and 'Water body' could barely. Thus, ecological attributes degree was very low. In addition, results of investigation whether the difference of ecological attributes degree between the two types of urban park, also statistically analyzed that there is no difference. Therefore, when establishing the composition of the future plans of the city park, to take full account of the ecological situation in the surrounding parkland, and identify the ecological potential with the parkland. Next, it should be designed and planned of the park that fully utilizing the potential of this ecological attributes.
