This study has intended to build ecological networks in consideration of life-zones inside Cheongju city through biotope grade, GIS network analysis etc. This study consisted of following three steps. First, we selected core districts and core spot districts using land use patten and biotope grade. The core district included the first grade of biotope and forest land. The core district consisted of two sectors : east axis core, Uam mountain; west axis core, Bumo mountain. The core spot district included the first grade of biotope. The core spot districts consisted of two sectors : north axis base core, Myongshim park; south axis base core, Guryong park. Second, the base district included the second grade of biotope and park and school. We used buffering analysis within 500m of the base district and selected the new base district. Third, we connected core districts and base core districts using least cost analysis of GIS. Thus we built comprehensive ecological networks in consideration of life-zones through GIS.

본 연구의 목적은 용인시에 대한 생태발자국 지수 산정 및 변화분석을 통해 용인시의 환경용량 추이를 분석하고, 이를 바탕으로 용인시의 도시개발 및 계획의 방향을 제언하는 것이다. 이를 위하여 용인시를 대상으로 1993년, 2003년, 2013년에 걸친 생태발자국 지수 분석을 실시하였으며, 지수분석 결과를 바탕으로 용인시의 토지이용 변화와 개발패턴의 문제점에 대하여 분석하였다. 또한 GIS(Geographic Information System)를 기반으로 한 토지피복도와 생태발자국 지수의 비교를 통해 용인시 토지이용의 변화를 환경적 측면에서 분석하였다. 본 연구 결과는 다음의 세 가지로 요약될 수 있다. 첫째, 용인시의 총 생태발자국 지수는 1993년 3.20(gha), 2003년 6.50(gha), 2013년 11.15(gha)로 산정되었으며, 이는 용인시의 생태발자국이 세계적으로 요구되는 1인당 생태발자국 1.8(gha)는 물론, 한국 전체의 1인당 평균 생태발자국인 3.56(gha)을 훨씬 상회하는 수준으로, 지역 환경용량에 비해 과도한 자원소비가 이루어지고 있다는 것을 보여주고 있다. 둘째, 1993년부터 20여 년간 용인시의 생태발자국을 부문별로 분석한 결과, 산림부문의 생태발자국이 가장 크게 증가하였으며, 다음으로 에너지 부문, 음식 부문, 건조환경부문으로 순으로 나타났다. 특히, 산림 생태발자국의 경우 1993년에는 가장 낮은 0.002(gha)였으나, 2013년에는 7.32(gha)로 급증했으며, 에너지의 경우도 0.87(gha)에서 2.38(gha)로 비교적 높은 증가율을 보였다. 이는 급격한 도시개발로 인한 목재수요와 목재생산력의 지나친 불균형 및 주거와 상업용지 개발에 따른 에너지 수요의 급격한 증가에 기인하는 것으로 분석된다. 셋째, 지난 10여 년간 생태발자국과 산림 및 건조환경 토지피복의 변화를 관찰한 결과, 산림부문의 생태발자국이 가장 크게 확대되었으며, 실제 훼손된 산림면적 또한 증가된 건조환경 면적에 집중되어 있음을 알 수 있었다. 에너지 부문의 생태발자국 또한 급격한 증가를 보여주고 있는데, 이는 토지피복도 분석에서 알 수 있듯 건조환경부문, 특히 상업시설과 도로 및 철도용지의 급증에 크게 기인하는 것으로 분석되었다. 이는 향후 용인시가 개발 시 산림의 훼손을 최소화하고, 녹지면적을 확대해야 할 필요성을 제기하고 있으며, LPG 등 화석연료의 소비를 줄이는 대신 신재생에너지의 확대를 적극적으로 추진해야 한다는 근거를 제공할 수 있다.

The new town in Korea, developed as a large-scale housing plan, has created urban ecological corridors to provide habitat and movement routes to wildlife and to promote natural ecological flow. This study aimed to investigate the use of wildlife in 10 ecological corridors in Gwanggyo New Town through camera trap technology and confirm effectiveness by identifying environmental factors affecting the use of wildlife's urban ecological corridors. Our researchers installed 20 unmanned sensor cameras at each the entrance and exit of the ecological corridors, and monitored urban wildlife for 10 weeks. According to the monioring results, the main species in Gwanggyo New Town were identified not only raccons, cats, water deer, korean hare and avain but also magpies, dove, eurasian tree sparrow, ring-necked pheasant, and eurasian jay. The number of uses ecological corridors of urban residents was 801(13.49%), as high as that of urban wildlife (1,140, 19.20%), which was judged to have disturbed the use of ecological corridors by wildlife. However, most dominant species of urban wildlife are nocturnal so that, it was judged that they share home range with urban residents at a time interval. In addition, according to the correlation analysis results between the mammal using rate of the urban ecological corridors and environmental factors(ecological corridor-specific length, ecological corridor-specific width, cover degree, shielding degree, connected green area, separation of movement routes, and presence of streetlights), environmental factors were not statistically significant. However, the more the area of green space connected to ecological corridors, the more increasing the mammal using rate of ecological corridor(r=0.71, p<0.05). Therefore, the area of green space connected to the ecological corridors that is associated with rate of wildlife using corridors should be considered as a priority when developing an urban ecological corridors. In the future, this study will extend the observation period of the ecological corridors and continuously accumulate data by adding the number of observation cameras. Furthermore, it is expected that the results of this study can be used as basic data for the standards for urban ecological corridors installation.

In order to make plan for landscape construction by ecological methods in Yukong R & D Complex site, environmental factors and structure of plant community were investigated and analyzed around Yukong R & D Complex site of Daeduk. The result of this study were as follows: 1. In the result by the classification of TWINSPAN and ordination (DCA) techniques for analysing of plant community structure, thirty plant community structure, thirty plots were divided into four groups according to soil moisture and succession trends were seem to be from the development of subsidiary vegetation through Pinus densiflora, Quercus spp., Robinia psudoacasia community to Q. acutissima community. So this result was proposed to validity of vegetation introduction for planning of ecological landscape construction in studied site. 2. On the analysis of environmental factors by ordination techeniques, the plant community were divided by soil moisture. Soilcondition will be fertilized by introduction of broad-leaved tree and the development of succession trends from the present state of plant community to Q. acutissima community. 3. The problems of horiticultural places happened to studied site, so horiticultural places for ecological landscape construction was proposed planting techniques that were considered to soil suitability, economical efficiency, native species and wildlife. 4. If we attempt to ecological landscape designs on natural systems and use natural processes to achieve desired end-points, we are more likely to produce self-sustaining solutions.

Roof greening recently emerged to be an important issue of environmental policies in a city. To cover roofs of buildings with green vegetation gives chances not only to improve urban environmental function but also provides the opportunities of environmental learning and convenience for users in the building. This study aimed to give directions for roof greening plan to designers by acknowledging the relationships between ecological and utilizational effectiveness. 10 sites and 15 variables were adopted to measure the relationships. As a result, no positive correlations was found between them. One of the results in correlation analysis among variables, however, showed that the roof gardens have high utilizational effectiveness only when a green roof was made by focusing on ecological functions in addition to the concepts that will guarantee user's convenience such as accessibility, entrance and exit, facilities for convenience and learning. The results implies that a green roof has to be designed considering multi-functional effects. Correlation between species of vegetation and the number of daily users, average staying hours, and attending level for environment educational programs were not significant. These findings imply that when a green roof has to be take high utilizational effectiveness, both plentiful vegetation species and design concepts for users' convenience are should be considered.

This study was conducted to investigate the plant community and to propose ecological planning methods for urban environmental forest on Gaepo neighborhood park, Gangnamgu in Seoul. Thirty-six plots that the size of each plot was 10$\times$10m(100\ulcorner) were set up and the vegetation analysis was carried out. Field survey was executed Apirl, 1994. The actual vegetation was consisted of Poplulus$\times$albaglandulosa community(73.03%), Robinia pseudoacacia community(8.30%) P. $\times$ albaglandulosa-R.pseudoacacia community(1.81%) and environmental forest (15.22%) in the survey site. According to mean importance values of each plot, survey area were divided into ten forest communities. As for the analysis of plant community structure which was classified into ten forest communities, the importance values, ecological diversity, number of species, number of individuals, basal area and crown coverage of urban environmental forest were relatively lower than those of the native community. In urban environmental forest of Gaepo neighborhood park, it showed problems for the planting method. So urban environmental forest should be constructed considering ecological characteristics based on above results.

Anyang Stream Restoration Movement was started from 2001 for the construction of ecological city. The facilities for reuse of treated sewerage have been used since 2003 for improvement of water quality, maintenance of water quantity, river ecological restoration, and hydrophilic space. Thus, the Anyang city has been gradually transformed to eco-friendly city after the construction of Anyang stream and Hakui stream as natural rivers. In this study, biological and chemical methods as well as ecological indicators for Anyang mainstream and major tributaries were monitored for four years in between 2008 and 2012. The water quality and the diversity of species in most of the streams were found to be good except Anyang main stream. It appears that the influence of seasonal drying stream is almost disappeared except Sammak stream. Thus, the values for BOD (Biochemical Oxygen Demand) and BIP (Biological Index of Pollution) for Anyang main stream were found to be 5.27~3.42mg/l and 4.51~5.50, respectively. This is considered to be caused by the reused water quality of treated wastewater being exceeded the design criteria or by the non-point source of contaminants around the stream. However, entire section of tributaries shows I, II grade as a good water quality.
