在各类创新中，smart settlements 和 urban digital twins (UDTs) 已成为变革性工具，使规划者、政策制定者和公民能够模拟、预测和优化城市系统，以实现可持续性和韧性。本文通过新加坡（Virtual Singapore）、赫尔辛基（Helsinki 3D+）和荷兰（Rotterdam 及 CLIMATE-IMPETUS）的实证案例研究，探讨数字孪生技术如何支持气候适应性城市发展。通过整合人工智能 (AI)、地理信息系统 (GIS) 和物联网 (IoT) 技术，数字孪生构建了具备实时监测、情景测试和风险建模能力的虚拟环境。

Among these innovations, smart settlements and urban digital twins (UDTs) have emerged as transformative tools that allow planners, policymakers, and citizens to simulate, predict, and optimize urban systems for sustainability and resilience. This article explores how digital twin technology can support climate-resilient urban development through empirical case studies from Singapore (Virtual Singapore), Helsinki (Helsinki 3D+), and the Netherlands (Rotterdam and CLIMATE-IMPETUS). By integrating artificial intelligence (AI), Geographic Information Systems (GIS), and Internet of Things (IoT) technologies, digital twins create virtual environments capable of real-time monitoring, scenario testing, and risk modeling.
