摘 要
城市热岛效应作为城市化进程中的典型环境问题，对城市生态系统和居民生活质量产生深远影响。本研究旨在系统分析城市热岛效应的影响因素并提出有效的缓解对策。通过文献综述、实地监测与数值模拟相结合的方法，选取典型城市区域为研究对象，获取了高分辨率的地表温度数据，深入探讨了下垫面特性、城市形态、人为热源以及气象条件等因素对城市热岛强度的作用机制。结果表明，不透水面比例增加、绿地水体减少及建筑物密集度提高均会显著加剧城市热岛效应；同时发现局地环流和风速变化对热岛强度具有重要调节作用。基于上述研究成果，提出了构建多层次绿色空间体系、优化城市布局结构、推广低碳节能技术等综合缓解策略。本研究创新性地引入多源数据融合分析框架，实现了对城市热岛效应时空特征的精准刻画，并建立了量化评估模型，为城市规划与管理提供了科学依据和技术支持，有助于推动可持续城市发展理念的落实。

Abstract
Urban heat island (UHI) effect, as a typical environmental issue accompanying urbanization, has profound impacts on urban ecosystems and residents' quality of life. This study aims to systematically analyze the influencing factors of UHI and propose effective mitigation strategies. By integrating literature review, field monitoring, and numerical simulation, this research selected typical urban areas as study ob jects, obtaining high-resolution land surface temperature data. The study delved into the mechanisms by which underlying surface characteristics, urban morphology, anthropogenic heat sources, and meteorological conditions influence UHI intensity. Results indicate that an increase in impermeable surface ratio, a decrease in green spaces and water bodies, and higher building density significantly exacerbate UHI effects; it was also found that local circulation and wind speed variations play crucial roles in regulating UHI intensity. Based on these findings, comprehensive mitigation strategies were proposed, including the development of multi-level green space systems, optimization of urban layout structures, and promotion of low-carbon energy-saving technologies. Innovatively, this study introduced a multi-source data fusion analysis fr amework, achieving precise characterization of UHI spatiotemporal features and establishing a quantitative evaluation model, thereby providing scientific evidence and technical support for urban planning and management, contributing to the implementation of sustainable urban development concepts.
