Under the light fog condition, UHI intensity is the strongest in autumn, but under other weather conditions, it is the strongest in winter. 四季相比,除雾条件下秋季城市热岛强度最强外,其他天气条件下均为冬季最强;
UHI intensity is higher in night than in daytime under different weather conditions. 不同天气条件下,夜间城市热岛强度均高于白天;
Analyses on the Characteristics of Beijing Summer Urban Heat Island ( UHI) and Its Meteorological Fields 北京市夏季城市热岛特征及其近地层气象场分析
With observational temperature data of July and August in Beijing from 1993 to 2003, the interannual variability and the environment effect of the UHI ( urban heat island) are studied. 根据1993~2003年北京地区气象台站7、8月的温度资料,分析研究了近10年来北京夏季城市热岛的变化及其环境效应。

During the same period, UHI expanded from center of the City to east, north and northwest areas. 1994年杭州市热岛集中在城中心,到了2004年,热岛范围已由城中心向杭州市西北部、北部和东部扩张;
Perform systematic analysis on the UHI intensity tendency rate and UHI contribution rate to the temperature increase using three types of temperature tendency rate for both urban and suburban areas. 利用城区和郊区3种温度的倾向率分析了城市热岛强度倾向率和热岛增温贡献率。
It is found from lots of domestic and foreign results that UHI effect exists in all cities. 国内外大量的研究结果表明,所有城市都存在城市热岛效应。
The UHI effect in winter maintain longer than in summer. 冬季热岛效应维持时间长于夏季。
Based on the previous quantitative study, we discussed the mechanism of generation and impact on urban scale. Several conclusions have been drawn as follows: ① The source of UHI generation is the rapid conversion of suburban land to urban land. 在前面定量分析研究基础上,深入探讨了城市尺度下城市热岛产生与影响机制,归纳为:①城郊用地向城市建设用地的快速转变是产生城市热岛的本源。
In this thesis, we employ remote sensing, GIS and numerical simulation technology to analyze the generation and impact mechanism of UHI on an urban scale in Hangzhou, and explore the UHI mitigation technology and system development. 本论文应用遥感和GIS以及数值模拟技术,选取杭州为研究实例,着重分析城市尺度下城市热岛产生与影响机制,以探索城市热岛缓减技术与系统开发作为主要研究内容。
The results provide theory base of using heat reflection and thermal resistance technology to decrease rut and mitigate UHI effect. 为应用热反射与热阻技术控制车辙病害和缓解热岛效应提供了理论基础。
The changes of urban spatial pattern and the destruction of ecological environment aggravate the UHI. 城市空间格局的改变以及自然生态格局的破坏加剧了城市热岛效应。
The differences of urban land also have effects on the UHI. 城市用地性质的差异对城市热岛也有不同程度的影响。
In case that wind speed was small in summer, UHI intensity was weakened with increasing wind speed. 夏季风速较小的情况下,热岛强度随风速增加而减弱。
At the same time, with the process of urbanization in our country, the Urban Heat Island effect becomes a more and more serious environment problem. The UHI effect harm citizen health and increase power demand for cooling in summer. 同时,伴随着我国城市化进程,城市热岛效应成为了一个日益严重的环境问题,既危害城市居民健康,又造成大量能源消耗。
Anthropogenic heat emissions and air pollution are an important factors for the UHI. 人为热的排放以及空气污染是产生热岛的重要影响因素。
As a typical area of shanghai, Quantitative Analysis are used in the relation of URI and density of population, relation between URI and percentage of greenery coverage, the UHI crowding level and the wind speed. 以上海市为典型区域,分析了热岛比例指数与人口密度、绿化覆盖率等的关系。同时分析了热岛聚集度与风速的关系,对热岛形成的一些成因进行了定量的分析。
Urban heat island ( UHI) effect is an important climate impact caused by urbanization. 城市热岛效应是城市化对区域气候影响的重要方面。
The center of UHI is mainly distributed in the industrial land, commercial land and residential land-intensive areas. 城市热岛中心主要分布在工业用地、商业用地以及居住用地密集区域。
The excess mortality in the downtown area is bigger than that in the rural area, which is closely associated with urban heat island ( UHI) index. 热浪期间市区超额死亡率要远大于郊区,超额死亡率的地区分布特征和城市热岛强度指数有着密切的联系。
Perform UHI characteristic analysis for Changsha based on the average data from multiple selected representative stations located in both urban and suburban areas. 选取具有代表性的城区和郊区多个站点的平均值对长沙城市热岛效应特征进行分析。
Therefore, it is helpful to improve the thermal environment, reduce energy consumption, and make urban human settlements development sustainable by analyzing UHI qualitatively and quantitatively. 因此,对城市热岛效应进行定性、定量分析研究,有助于改善城市热环境、降低能源消耗、实现城市人居环境的可持续发展。
