Recently, summer high temperature events caused by climate change and urban heat island phenomenon have become a serious social problem around the world. Urban areas have low albedo and huge heat storage, resulting in higher temperatures and longer lasting characteristics. To effectively consider the urban heat island measures, it is important to quantitatively grasp the impact of urban high temperatures on the society. Until now, the study of urban heat island phenomenon had been carried out focusing only on the effects of urban high temperature on human health (such as heat stroke and sleep disturbance). In this study, we focus on the effect of urban heat island phenomenon on air pollution. In particular, the relationship between high temperature phenomena in urban areas during summer and the concentration of photochemical oxidant is investigated. High concentrations of ozone during summer are confirmed to coincide with a day when the causative substances (NO2,VOCs) are high in urban areas during the early morning hours. Further, it is noted that the night urban heat island intensity is large.. Finally, although the concentration of other air pollutants has been decreasing in the long term, the concentration of photochemical oxidant gradually increases in Daegu.

Significant air temperature increases in urban areas are known as the heat island phenomenon in a global scale. Therefore, we propose numerical model in order to analyze quantitative effects of building environmental factors on the heat island phenomenon in urban area. In this paper, we propose a predicting model to analyze the heat island phenomenon quantitatively. Using this model, numerical simulation is performed in order to analyze quantitative effects of many factor on the heat island phenomenon.

Remarkable air temperature increases in urban areas are known as heat island phenomenon. In this study, we analyzed the effects of renewable energy on the heat island phenomenon in urban area by numerical method. The results showed that the use of renewable energy reduces the building energy use in urban area and contributes the alleviation of the Urban Heat Island Effects.

The impermeable area on the surface of city has been increased as buildings and artificial landcover have continually been increased. Urban development has gradually decreased the green zone in downtown and alienated the city from the natural environment on outskirt area devastating the natural eco system. There arise the environmental problems peculiar to city including urban heat island phenomenon, urban flood, air pollution and urban desertification. As one of urban plans to solve such problems, green roof system is attracting attentions. The purpose of this study was to investigate the heat reduction effect according to the development of green roof system and to quantify the heat reduction effect by analyzing through simulation the heat environment before and after green roof system. For thermal environment analysis, Thermo-Render 3.0 was used that was developed by Tokyo Industrial College to simulate. The simulation showed that the heat island index before and after the development of tree-planting on rooftop changed maximum $0.86^{\circ}C$ and the surface temperature changed about $20^{\circ}C$. Only with lawn planting, heat reduction effect was great and it means that the green roof system in low-management-light-weight type is enough to see effect. The simulation identified that only lawn planting for green rooftop brought such difference and could lower the heat island index at a narrow area. It is judged that application of green roof system to wider areas might relieve urban heat island phenomenon positively.

도시지역 폭염에 대한 보다 나은 이해를 위해서는 토지이용의 총량적 이해와 더불어서 토지이용의 공간적 위치분배와 폭염현상과의 관계성 이해도 필요하다. 본 연구의 목적은 군집개발과 파편화된 개발이 폭염일수와 순위상관관계를 보이고 있는지를 살펴보는 것이다. 주요연구방법으로는 형태학적공간패턴, 공간자기상관성, 스피어만상관성 분석을 이용하였다. 연구대상지는 대구, 광주, 울산, 부산, 대전광역시이며 폭염지표는 30년간 연간폭염일수로 설정하였다. 본 연구는 군집개발 유무보다는 나홀로 개발 등의 파편화개발방식이 폭염에 부정적이라는 점을 보여주고 있으며 이는 곧 개발형태가 폭염과 관계가 있음을 의미한다.

Significant air temperature increases in urban areas is well known as the heat island phenomenon in a global scale. Therefore, we propose numerical model in order to analyze quantitative effects of building environmental factors on the heat island phenomenon in urban area. In this paper, thermal property of upper atmosphere is experimentally investigated for Sakae, Nagoya Japan. In conclusion, it was confirmed that the boundary layer of a urban canopy existed near the altitude of 139 m.

Recently, the heat island phenomenon in which the temperature of a city part rises from the circumference ground has developed into a big problem. In this study, we aimed at examining the impact of increasing vegetation in urban areas to reduce the heat island phenomenon by taking the Fukuoka City of Japan as a case. In order to discuss the relation between vegetation environment and the heat island phenomenon, we have calculated Normalized Difference Vegetation Index (NDVI) and mapped the spatial vegetation distribution. These are then compared with the heat island phenomenon investigations in Fukuoka City. The results of the study revealed that the areas showing comparatively lesser heat island phenomenon are those having increased vegetation.

도시의 인구 증가와 이에 따른 개발로 인한 도시화는 도시 내 열섬현상과 같은 다양한 환경문제를 유발할 수 있다. 특히 계획적으로 구축되는 신도시의 경우 짧은 기간에 진행되는 급격한 도시화로 인한 도시 기후의 변화를 분석하기에 적절한 연구대상지로 여겨진다. 본 연구에서는 Landsat-8 Operational Land Imager/Thermal Infrared Sensor (OLI/TIRS) 위성영상을 활용하여 세종특별자치시 내 행정중심복합도시의 2013년부터 2020년 개발계획에 의한 토지피복 변화와 이에 따른 표면 열섬현상의 변화를 분석하였다. 이를 위해 위성영상에서 제공하는 열적외선 밴드값과 방사율을 고려하여 지표면온도를 산출하고, 이를 기반으로 표면 열섬현상 강도와 Urban Thermal Field Variance Index (UTFVI)의 변화분석을 수행하였다. 개발이 진행됨에 따른 토지피복 변화 및 피복별 열섬현상 강도의 차이 확인을 위해 환경부에서 제공하는 중분류 토지피복지도를 활용하였다. 분석 결과, 연구지역의 시가화 면적은 15% 증가하였고 자연식생은 28% 이상 줄어든 것이 확인되었다. 또한 이에 따른 열섬현상의 확장 및 강도 증가가 관측되었고, 열섬현상이 발생된 지역의 생태적 수준은 매우 낮은 것을 확인하였다. 본 연구를 통해 급격한 도시화에 따른 열 환경의 정량적 변화 및 생태적 수준을 확인하고, 주거환경의 열 환경 개선을 위한 추가적인 정책의 필요성이 제시될 수 있다.
