도시자연은 물리적 환경개선 기능은 물론 사회적, 정서적 측면에서도 중요한 역할을 한다. 특히, 학교에서 생활하는 시간이 많은 우리나라의 경우 학교 옥외공간을 비롯하여 인근에 조성된 녹지공간은 자연체험의 기회가 적은 도시 아이들이 가장 쉽게 자연을 접할 수 있는 일차적인 장소이다. 본 연구에서는 우리나라 대도시의 녹지현황을 학교 주변을 중심으로 살펴보고자 한다. 서울시 185개 초등학교를 선정하고, 학교 옥외공간을 포함한 반경 300m 이내(본 연구에서 '학교존'으로 정의) 주변 녹지 현황을 RapidEye 다중분광 인공위성 영상을 사용하여 분석하였다. 학교존 평균 녹지율은 약 21%이고, 최고 74%에서 최소 0.7%까지 편차가 매우 큰 것으로 나타났다. 그리고 과반수 이상의 학교존 녹지율이 20% 미만이다. 학교존 녹지율이 높은 학교 대부분이 산기슭에 위치하고 있어 산림면적이 학교존 녹지율을 높이는데 기여한 것으로 분석되며, 산림녹지의 경우 식생활력 또한 기타 도심지에 조성된 조경수목식재지보다 상대적으로 높은 것으로 나타났다. 반면, 학교존 녹지율이 낮은 학교들 대부분은 고밀 주택지 인근에 위치하고 있으며, 녹지의 식생활력 또한 상대적으로 낮게 나타났다. 도시산림을 제외한 시가화지역에서 학교존 녹지의 많은 부분을 차지하는 것은 아파트단지내 조경녹지시설이며, 그 밖에 친환경적인 학교 옥외공간이나 가로공원 등 도시오픈스페이스가 차지하는 비중은 미미하다. 이러한 현실을 감안하여, 도시계획적인 맥락에서 학교존 녹지율이 낮은 지역을 우선 대상으로 학교숲 조성사업을 지원하거나 주변지역의 옥상녹화를 장려하고, 학교주변 아파트단지내 녹지공간을 학교옥외공간과 유기적으로 연계하여 쉽게 접근할 수 있는 도시오픈스페이스로 개방하는 등의 체계적인 대책 마련이 필요하다고 하겠다.

성인을 중심으로 건강도시를 논의한 기존 연구와 달리, 본 연구는 청소년 비만에 영향을 미치는 도시 특성을 규명하고자 했다. 도시특성이 청소년 비만에 영향을 미치는 기제(mechanism)에 대한 엄격한 의학적 이론이 드물기 때문에 본 연구는 선행연구 검토를 통해 청소년 비만에 영향을 미칠 것으로 판단되는 도시특성을 도출하고, 이를 토대로 회귀분석을 했다. 교육부의 학생 신체검사 자료를 이용하여 서울 시내 각 학교별 비만학생 비율을 종속변수로 설정했다. 선행연구를 통해 파악한 도시특성을 각 학교를 중심으로 하는 일정 반경(500m, 1000m, 1500m) 내에서 버퍼분석(buffer analysis)으로 측정한 뒤, 독립변수로 설정했다. 회귀분석한 결과, 성인교육수준이 낮을수록, 단독 연립 다세대 다가구 주택이 많을수록, 노후 주택이 많을수록, 토지이용혼합도가 낮을수록 비만청소년이 많았다. 인구밀도, 대중교통 접근성, 도시공원 등은 유의하지 않았다. 이러한 결과를 토대로 청소년 비만율을 낮추거나 관리하기 위한 도시계획 방안이 앞으로 더욱 논의되어야 할 것으로 보인다.

This study investigated differences in nutritional knowledge and eating habits of adolescents living in rural and urban areas of Inner Mongolia, China. A survey was conducted on 869 middle school students in Hohhot, Inner Mongolia: 436 from urban and 433 from rural school. Subjects answered a questionnaire about socio-economic characteristics such as parents' education level and family affluence scale, nutritional knowledge, needs for nutritional education and food habits. Levels of parents' education (p<0.001) and family affluence (p<0.001) were significantly higher in urban students. Nutritional knowledge level of urban students was higher than that of their counterparts (p<0.001). However, rural students reported higher needs for nutritional education (p<0.001). Rural students more frequently consumed snacks (p<0.001) and instant noodles (p<0.001) than urban students. However, consumption frequencies of lunch (p<0.001), dinner (p<0.001), fast food (p<0.001), fruits (p<0.001), vegetables (p<0.001), and milk (p<0.001) were higher in urban students. Considering differences in eating patterns between urban and rural students in Inner Mongolia, appropriate nutritional education programs and nutritional policies should be established for rural students to promote a healthy diet.

The honey bee has a crucial ecological status for maintaining the natural ecology system. Pollination mediations by honey bees are recognized as an efficient way to enhance the quality of biological diversity and green areas in the nature and the urban ecological system. However, the population of bee around the world is decreasing and we do not know exactly how bees react to the physical environment in the urban area. This study is a basic research for the improvement of pollination services in the Korean urban ecological system. It aims to induce and review environmental variables which have high relations with the activities of pollination mediation insects in the urban area. The study established a Maxent model using five urban environmental variables that reflect the ecology of Bombus ignitus and the place information where Bombus ignitus appears in 18 spots of Seoul city, and compared with previous research results on Apis millifera. Bombus ignitus preferred places with more natural environments such as mountain forest areas and vicinities of streams. They preferred Stratified Tree Area the most among the vegetation types existing in the urban area. Comparing chicken models, both species saw their response value drop as the building coverage rose. In the case of Apis millifera and Bombus ignitus variables, the response value of both species was high in 10 out of 20 types. The result of this study is expected to provide basic information for improving the pollination services in the Korean urban area and to be utilized as the basic materials for the future urban planning.

세계 곳곳에서는 새로운 도시들이 계속 건설되고 있으며, 도시로 이주하는 사람들의 수 또한 급증하고 있다. 현재 약 54 퍼센트의 세계 인구가 도시에 살고 있으며, 2050년까지 66 퍼센트로 증가할 것으로 예측된다. 따라서 도시지역 관리는 전지구적 지속 가능한 발전에 있어 가장 중요한 과제 중 하나라고 볼 수 있다. 효과적인 도시지역 관리를 위해서는 도시 주민들에게 미학적, 정신적 그리고 보건적 혜택을 제공하는 도시 내 녹지지역의 유지관리가 핵심이다. 그러나 녹지지역의 경제적 가치 평가의 어려움으로 인해 사회에서는 이러한 녹지지역 혜택의 필요성을 충분히 인식하지 못하고 있다. 이에 본 연구는 송도 센트럴 파크가 제공하는 미학적 혜택의 경제적 가치를 추정하기 위하여, 공원 조망이 주변 아파트 가격에 긍정적인 영향을 미치는지에 대해 헤도닉 가격 기법을 사용하여 분석하였다. 분석 결과, 아파트 가격과 송도 센트럴 파크 조망 간에 양의 상관관계가 존재하며, 조망이 있는 아파트의 가격이 조망이 없는 아파트의 가격에 비해 5 퍼센트 정도 높은 것으로 추정되었다. 또한 송도 센트럴 파크와의 거리 또한 아파트 가격에 영향을 미치는 것으로 추정되었다.

Urban parks are progressing but are in chaos in the twenty-first century. Therefore the purposes of this study are to consider critically and classify the new paradigm of urban parks. Urban parks are one of the space products, and progressing aspects can be divided into three parts; supply, demand and market aspects. In the abstract, urban parks' progress represents process, openness or voidness, general and cultural ecology, productivity, experience program, identity or sense of place, carriers of urban regeneration, urban infrastructure, community space, multi-layered activity, active space, communication with urban space, tool of low carbon strategy and consilience. But urban parks have come under increased criticism about the long period development on trees growth, covering open space, limitation of general and cultural ecology, production, activity programs, identity and community space, visible urban regeneration, economic validity, urban sprawl, not using as the low carbon strategy, and finally negative consilience with contiguous fields. We collected these critical consideration about progressing urban parks, and proposed urban agricultural park as one of the alternative urban parks. This is closely connected with sustainable region development, low-carbon society, local food, well-being, Lohas paradigm and amenity of urban life.

As urban growth continues, the earth ecosystem is increasingly dependent on the patterns of urban growth. The impact intensity from urban growth is expected to change predictably with distance from the urban center. However we can't fully understand yet how urban development pattern affects urban ecosystem. In researches about urban ecosystem, it is important to relate the spatial pattern of urbanization to ecological processes. So we used gradient analysis with time data; 1980's, 1990's and 2000's. We attempted to quantify the urban spatiotemporal impacts in Daejeon-city and Cheonan-city, Korea, along a 75km long and 3km wide transect. Through the results, we found the impacts range of urbanization with urban development process of two cities. When the urban growth was concentrated on in both cities, the impacts intensity and range were much stronger and wider. As a result, in urban planning or green space planning, we have to consider suitable urban development forms with surrounding areas, and make legal clauses which limits landuse change. This quantifying the urban gradient is an important step in understanding urban ecology.

This study investigates the influence of anthropogenic heat (AH) release on urban boundary layer in the Gyeong-In region using the Weather Research and Forecasting model that includes the Seoul National University Urban Canopy Model (SNUUCM). The gridded AH emission data, which is estimated in the Gyeong-In region in 2002 based on the energy consumption statistics data, are implemented into the SNUUCM. The simulated air temperature and wind speed show good agreement with the observed ones particularly in terms of phase for 11 urban sites, but they are overestimated in the nighttime. It is found that the influence of AH release on air temperature is larger in the nighttime than in the daytime even though the AH intensity is larger in the daytime. As compared with the results with AH release and without AH release, the contribution of AH release on urban heat island intensity is large in the nighttime and in the morning. As the AH intensity increases, the water vapor mixing ratio decreases in the daytime but increases in the nighttime. The atmospheric boundary layer height increases greatly in the morning (0800 - 1100 LST) and midnight (0000 LST). These results indicate that AH release can have an impact on weather and air quality in urban areas.
