Appropriate landscape configurations significantly mitigate rural thermal degradation. However, limited research exists on seasonal thermal comfort and the interconnections among landscape elements. Using ENVI-met software and field measurements, this study analyzed the microclimate of Dayuwan Village Square in Wuhan City. Fifteen design scenarios, including tree planting, building greening, albedo adjustment, and expanded tree coverage, were quantitatively evaluated to assess their impact on outdoor thermal comfort. Additionally, synergistic interactions between mitigation strategies were explored. The study found that increasing evergreen tree coverage by 50% has minimal impact on comfort during winter and spring. However, it significantly reduces temperatures in summer and autumn, resulting in average predicted mean vote (PMV) decreases of 0.315 and 0.643, respectively. Additionally, this strategy optimizes PMV values at 18:00 on extreme days, with a 0.102 decrease in summer and a 0.002 increase in winter. This research offers practical and sustainable guidance to designers for enhancing mitigation effects through optimal landscape configuration, providing a technical framework for rural environmental improvements.
适当的景观配置可以显著减轻农村热退化。然而，关于季节性热舒适以及景观要素之间的相互关系的研究还很有限。本研究使用 ENVI-met 软件和现场测量，分析了武汉市大圻湾村广场的微气候。评估了十五种设计方案，包括植树、建筑绿化、反照率调整和扩大树木覆盖范围，以定量评估它们对户外热舒适的影响。此外，还探讨了缓解策略之间的协同作用。研究发现，常绿树木覆盖率增加 50%对冬春季节的舒适度影响不大。然而，它显著降低了夏秋季的温度，导致平均预测平均投票（PMV）分别降低 0.315 和 0.643。此外，该策略在极端日的 18:00 优化了 PMV 值，夏季降低 0.102，冬季增加 0.002。本研究为设计师通过优化景观配置来提高缓解效果提供了实用且可持续的指导，为农村环境改善提供了技术框架。
