中文摘要: 全球正经历快速、高强度的城市化,导致城市热岛加剧,并对城市、区域乃至全球许多的生态环境要素直接或间接地产生多方面的影响,与人类福祉密切相关。遥感具有宽覆盖、信息量大、重复观测周期短等优点,已成为地表城市热岛(Surface Urban Heat Island,SUHI)监测广泛采用的一种方法。针对前人相关研究对热红外数据源、监测指标及SUHI时空变化规律尚缺乏系统总结且内容需要更新等问题,本文首先分类评述了SUHI遥感监测所采用的热红外遥感数据源。其次将现有的SUHI监测指标分为土地覆盖类型驱动型、地表温度格局驱动型及两者复合驱动型3类来述评,详细介绍了它们的计算方法、应用案例及优缺点;并从日间变化、夜间变化及昼夜对比的变化3个方面述评了SUHI的年内时空变化规律;归纳了其年际变化规律。最后,依据现有研究结论中相互冲突或尚需深化的地方,指出几个潜在的关键问题或研究方向。

英文摘要: Rapid and high intensity urbanization is currently occurring in the world, resulting in increasingly more serious urban heat island phenomenon. Urban heat islands have direct and indirect impacts on various ecoenvironment factors of cities, regions, and the world, which are closely related to the human well-being. Remote sensing method has been widely used for Surface Urban Heat Island (SUHI) monitoring for its obvious advantages, such as wide range, huge amount of information, short observation cycle, among others. Considering the issue that existing studies have not systematically summarized the thermal infrared data sources, monitoring indicators, and the spatiotemporal variation patterns of monitoring results, and the related information needs to be updated, this study conducted a review of progress of surface urban heat island monitoring by remote sensing. First, we presented and classified the thermal infrared remote sensing data sources for the SUHI monitoring by remote sensing in previous studies. Second, we divided the monitoring indicators into three types, including land cover types-driven kind, Land Surface Temperature (LST) pattern-driven kind, and complex kind driven by both land cover types and LST pattern. We introduced the main indicator calculation methods and application cases in detail and analyzed their advantages and disadvantages. We then reviewed the intraannual spatiotemporal change regulation of the SUHI from three aspects, including diurnal variation, nocturnal variation, and comparative variations between day and night. We also considered the patterns of interannual changes. Finally, we proposed several key issues and potential research directions based on the research areas in which conflicting conclusions are found or research needs to be deepened in the existing studies.
