Urban development and population have augmented the increase of impervious land-cover. This phenomenon has amplified the effects of climate change and increasing urban island effects due to increases in urban temperatures. Seoul, South Korea is one of the largest metropolitan cities in the world. While land uses in Seoul vary, land cover patterns have not changed much (under 2%) in the past 10 years, making the city a prime target for studying the effects of land cover types on the urban temperature. This research seeks to generalize the urban temperature of Seoul through a series of statistical tests using multi-temporal remote sensing data focusing on multiple scales and typologies of green space to determine its overall effectiveness in reducing the urban heat. The distribution of LST values was reduced as the size of urban forests increased. It means that changing temperature of large-scale green-spaces is less influenced because the broad distribution could be resulted in various external variables such as slope aspect, topographic height and density of planting areas, while small-scale urban forests are more affected from that. The large-scale green spaces contributed significantly to lowering urban temperature by showing a similar mean LST value. Both of concentration and dispersal of urban forests affected the reduction of urban temperature. Therefore, the findings of this research support that creating urban forests in an urban region could reduce urban temperature regardless of the scale.

서울과 같은 대도시의 농경지는 인간의 간섭이 끊임없이 이루어지는 준자연지역으로 생산성보다는 도시의 생물다양성보존 및 경관다양성을 통한 일반시민의 자연체험이라는 측면에서 관리.보호될 필요가 있다. 그러나 도시지역의 농경지는 개발용지로 토지이용이 전환되어 급속히 감소하고 있다. 본 연구에서는 서울시를 대상으로 농경지 패취의 시간변화에 따른 토지이용변화를 살펴보고 서울시 비오톱유형도에 근거한 농경지 패취를 분석하여 서울지역 농경지의 경관생태학적 구조와 특성을 파악하고, 이러한 분석결과를 토대로 생물다양성 증진을 위한 농경지 관리모델을 구상하는데 그 목적이 있다.

Over the years, there have been many school construction projects resulting from the activation of the Build Transfer Lease(BTL). Furthermore, due to the need for the qualitative expansion of educational facilities, as well as the attempt to fulfill social requirements and the need for eco-friendly learning environments, these projects have become a major priority. As a result, the government has established a proper standard for school construction based on a certain level of green certification that has been mandated. The aim of this study is to assess the status of schools as relates to the composition of the ecological environment surrounding them. These elements of eco-friendly school facilities are larger than the educational environment and are directly related to the environmental and educational effects on the students. Looking at the overall results of this study, the areas of ecological environment outside school are found to be inadequate. Therefore, this field needs to adopt more realistic goals, and focus on the areas where the most improvement is needed.

The residents, living in multi-family housing, prefer to have healthy and natural outdoor environmental for better human and environment quality. Thus, providing the high qulity of amenity has become a popular word in site planning and housing developments field. However, the scope and definition of amenity have not yet clearly identified and it becomes and issue in planning and development field. The purpose of this study isto examine and to evaluate the amenity and its implicationi for site planning so that analysis methods such as to interview and survey with residents were carried out. The results of this study are summarized below; The amenity of residential environment means total environmental quality to the residents in a broad sense. Abundent green environment would be very important factor to increase the amenity of residential environment so that the expansion of green field would improve the quality of multifamily housing. The expansion of green environment and biotope was the most important factor to increase the symbiosis system between residents and outdoor environment. And the amenity should be conformed to the certain standand of environmental quality and the high quality of amenity would be increased significantly in the future for residental developments. Thus, it should be accomplished by preparing practical methods in means of discriminative strategy products planning principle.

우리 나라의 도시생태계 평가제도는 도시계획법에 의해 시행되는 제도와 환경관련떱에 의해 시행된는 제도로 구분된다. 도시계획법에 의한 평가제도는 개발행위허가기준과 도시계획 환경성검토가 있으며, 환경관련법에 의해 시행되는 제도는 환경영향평가와 사전환경성검토가 있다. 도시생태계 평가제도는 그 동안 개발지향적인 토지이용정책으로 인해 체계적인 발달이 이루어지지 않았으며, 평가기법도 입목본수도 및 녹지자연도 등을 제외하고는 객관적인 평가기법이 개발되지 알았다. 또한 평가 결과 보전가치가 높은 지역에 대한 보전대책 및 계획과정과 사후에 대한 평가가 부족하다는 문제점을 가지고 있다 우리 나라의 도시생태계 평가제도가 활성화되기 위해서는 다음과 같은 개선방안 마련이 필요하다. (1) 비오톱지도와 같은 객관적인 도시생태계 평가기법 개발, (2) 평가결과 보전가치가 높은 지역에 대한 보전지구 지정 및 훼손에 대한 보상 방안 마련, (3) 도시개발계획과 생태계 보전계획 수립의 병행 및 사후평가 시행

This study is one of the processes to build the artificial wetlands in the urban area. The purpose of this study was to survey biotic or physical environments, and to review modelling techniques to find out the ecological structure and function. Case study site was the Bangdong wetland in the north west side of Taejon metropolitan city. The number of species of insects decreased during monitoring. But the number of individuals of insects decreased abruptly after increasing. And then biodiversity index dropped and dominance index increased. So the structure of biotopes was affected by weather conditions. And in the restricted area such as urban area, the changes of insects were affected sensitively by not physical but environmental changes. As for birds, the number of species was reduced a little, but the number of individuals increased abruptly. And dominance index increased slowly. The changes of water depth and increase of temperature affected the habitat condition of vegetations and birds, so the dominance index of specific species increased. In urban areas it is necessary to continue management for water environmental changes, such as the depth and area of water. The number of species of fishes was reduced a little, but the number of individuals increased abruptly. And dominance index and biodiversity index decreased slowly. But the water environments was so changeable that it is difficult to explain current status as some specific trends. The number of species of reptiles and amphibians changed little, but the number of individuals increased abruptly. And dominance and biodiversity were not changed. The changes of water depth and temperature affected the habitat of every species the environmental changes affected.

The mixed rural city is adjusting to change by urbanization. The recent landcover change in mixed rural city is an important factor that changes structure and function of regional ecosystem. Landscape ecology is an integrated ecology widely available for environmental science such as nature conservation and sustainable land-use planning. As the concern about environmental quality rises, many studies are trying to create and conservate for biotop. The creation of biotop is related to the plan and management of the effective landuse because the important factor to change the structure and function of ecological area in the country. This study was carried out to establish the foundation of the landuse plan to analyze the change of landuse and to plan the scheme in creating biotop and landuse. We used the approach of ecological landscape and using landscape indices with RS(Remote Sensing) and GIS(Geographic Information System) technology, spatio-temporal variations of areas and distribution of forest patches were examined in the Sunghwan in Chonan from 1985 to 1996. A result of this study showed that the area of forest and paddy decreased by urban sprawl. The size of patch in the forest and agriculture had been smaller and irregular form, heterogeneity of size of forest and agriculture patches within sub-basin was increased, pattern of forest and agriculture patches decreased the corridor and network from 1985 to 1996.
