在过去的几十年里，人们对城市热岛现象的研究不断深入，并取得了很大的进展。尽管简单，但这一方便的概念促进了城市环境界科学研究和政策制定过程的重大进展。然而，城市和农村二分法的过度简化和不足，继承了城市热岛的概念，是越来越明显的今天在不断城市化的世界。在这项研究中，我们进行了全面和深入的调查，城市和农村二分法固有的热岛定义的不足，从理论，技术和实践的角度。此外，根据最近的研究进展，我们敦促从根本上重新概念化的城市热岛，提出一个新的范式，通过治疗的总城市环境作为一个复杂的动态系统。新的框架拓宽了传统城市环境研究的前沿，利用复杂系统和数据科学的先进技术，包括复杂网络理论，机器学习技术，因果推理等。城市热岛的重新概念化也有望促进决策和城市规划，并避免片面性的单一和往往过于排他性的目的缓解热量。
Past decades have seen drastically increasing research effort and progress on the study of the phenomenon of urban heat island (UHI). Despite its simplicity, this convenient concept has promoted significant advances in scientific research and policy making processes in the urban environmental community. Nevertheless, the oversimplification and inadequacy of the urban-rural dichotomy, inherited in the UHI concept, is increasingly manifest today in the continuously urbanized world. In this study, we conduct a holistic and in-depth survey of the inadequacy of the urban-rural dichotomy intrinsic to the definition of UHI, from theoretical, technical, and practical perspectives. In addition, in the light of recent research advances, we urge to radically reconceptualize UHI by proposing a novel paradigm by treating the total urban environment as a complex dynamic system. The new framework broadens the frontier of conventional urban environmental study by utilizing advanced techniques of complex systems and data sciences, including complex network theory, machine learning techniques, causal inference, etc. The reconceptualization of UHI is also expected to foster decision making and urban planning, and to avoid the one-sidedness of the singular and often too exclusive aim of heat mitigation.
