摘要
随着城市化水平不断提高及城市空间密度日益增加,城市热岛效应不断加剧,导致极端气候发生范围和强度增加,对城市居民的身心健康构成威胁。城市热岛效应现已成为多学科研究关注的热点。对现有尺度下热岛效应研究方法的技术发展进行了梳理,分析其优缺点以及在不同尺度上的适用性;此外,对街谷尺度下热岛效应的影响因素进行分析;最后,就当前研究过程中存在的问题,从数据及评价方法等方面提出街谷尺度下城市热岛的研究进展与发展趋势。研究成果为紧凑型城市发展模式背景下,深入研究城市街谷热岛效应提供了参考,为缓解城市热岛效应提供了有效途径。
With the continuous improvement of urbanization level and the increasing urban spatial density,the urban heat island effect is intensifying,resulting in the increasing range and intensity of extreme climate,which poses a threat to the physical and mental health of urban residents.Urban heat island effect has become a focus of multidisciplinary research.The technical development of existing methods for studying heat island effect at different scales was reviewed,their advantages and disadvantages,and their applicability at different scales were analyzed.In addition,the influence factors of heat island effect on street and valley scale were analyzed.Finally,according to the existing problems in the current research process,the research progress and development trend of urban heat island at street valley scale were proposed from the aspects of data and evaluation methods.The research results provide a reference for the in-depth study of urban street valley heat island effect under the background of compact city development model,and to provide an effective way to mitigate urban heat island effect.
