Modeling thematic and spatial dynamic behaviors of urban heat islands (UHIs) over time is important for understanding the evolution of this phenomenon to mitigate the warming effect in urban areas. Although previous studies conceptualized that a UHI only has a single life cycle with spatial behaviors, a UHI can be detected to appear and disappear several times periodically in terms of thematic and spatial integrated behaviors. Such multiple behaviors have not yet been illustrated with proof or evidence. This study conceptualizes a UHI as an object which has thematic and spatial behaviors simultaneously and proposes several graphs to depict periodic life‐cycle transitions triggered by behaviors. The conceptualized behaviors have been modeled and implemented in an object‐relational database management system and temperature readings collected from numerous weather stations were interpolated as temperature images per hour. The results of this study indicate that the model could track the spatial and thematic evolution of UHIs continuously and reveal their periodical patterns and abnormal cases.

面向对象的城市热岛主题和空间行为跟踪

随时间推移对城市热岛（UHI）的主题和空间动态行为进行建模，对于理解这种现象的演变以减轻城市变暖的影响非常重要。尽管以前的研究将UHI概念化为只有一个具有空间行为的生命周期，但是就主题和空间综合行为而言，UHI可以检测到周期性地出现和消失多次。尚未通过证据证明这种多种行为。这项研究将UHI概念化为同时具有主题和空间行为的对象，并提出了一些图形来描述行为触发的周期性生命周期过渡。已将这些概念化的行为建模并在对象关系数据库管理系统中实施，并且将从多个气象站收集的温度读数作为每小时的温度图像进行插值。这项研究的结果表明，该模型可以连续跟踪UHIs的空间和主题演变，并揭示其周期性模式和异常情况。
