摘 要
城市热岛效应作为全球气候变化背景下城市化进程中的重要环境问题，对居民健康、能源消耗和生态系统平衡产生了显著影响。本研究旨在探索有效的缓解策略，以降低城市热岛效应的不利影响。通过综合运用遥感数据分析、数值模拟以及实地观测等方法，系统评估了不同土地利用类型、绿化配置及材料特性对城市微气候的影响机制。研究选取典型城市区域为案例，分析了高反射率材料、植被覆盖优化及水体引入等措施的实际效果，并构建了多情景对比模型以量化其长期效益。结果表明，合理规划绿地布局与增加地表反照率可显著降低局部气温，其中屋顶绿化和透水铺装的组合方案表现出最优的降温性能。此外，研究创新性地提出了基于动态反馈的城市热环境调控框架，能够根据不同季节和气候条件灵活调整缓解策略。这一框架不仅提升了缓解措施的适应性和经济性，还为城市规划提供了科学依据。总体而言，本研究为制定针对性的城市热岛缓解政策提供了理论支持和技术参考，同时强调了跨学科合作在解决复杂城市环境问题中的关键作用。

ABSTRACT
The urban heat island (UHI) effect, as a significant environmental issue in the context of global climate change and urbanization, has exerted notable impacts on public health, energy consumption, and ecological balance. This study aims to explore effective mitigation strategies to alleviate adverse effects of the UHI. By integrating remote sensing data analysis, numerical simulations, and field observations, the study systematically evaluates the mechanisms through which different land-use types, green space configurations, and material properties influence urban microclimates. A typical urban area was selected as a case study to analyze the practical effects of measures such as high-albedo materials, optimized vegetation coverage, and water body introduction. A multi-scenario comparison model was also constructed to quantify their long-term benefits. The results indicate that rational planning of green space distribution and increased surface albedo can significantly reduce local temperatures, with the combination of rooftop greening and permeable paving demonstrating the most optimal cooling performance. Furthermore, this study innovatively proposes a dynamic feedback-based fr amework for urban thermal environment regulation, which enables flexible adjustment of mitigation strategies according to seasonal and climatic conditions. This fr amework not only enhances the adaptability and cost-effectiveness of mitigation measures but also provides scientific support for urban planning. Overall, this research offers theoretical underpinnings and technical references for developing targeted UHI mitigation policies, while emphasizing the critical role of interdisciplinary collaboration in addressing complex urban environmental challenges.
