摘　　要：以华南理工大学五山校区为例,对湿热地区大学校园步行环境的热环境和风环境进行评价研究,探究周边水体、树木遮阴和建筑遮阴三个主要因素对步行环境微气候的影响,研究不同因素的组合与风环境指标差值以及热环境指标差值的相关性。选取夏季和春季具有代表性的不同因素组合测点的单日测量数据,研究华南理工大学步行环境春夏两季的日间风环境指标和热环境指标变化特征,评价不同因素组合在步行环境设计和优化过程中的作用和区别,以此得出多种步行环境微气候舒适的局部模型,以期为湿热地区大学校园的室外步行环境微气候改善提供参考借鉴。The thermal and wind characteristics of the university campus walking environment in humid and hot areas were evaluated in this study,taking the Wushan campus of the South China University of Technology as a case study.The influences of three main factors(surrounding water bodies,tree shade,and building shade)on the microclimate of the walking environment were investigated.The combination of different factors and the corresponding differences in wind environment indexes and thermal environment indexes were studied.The study focused on the core part of the campus,combined with the road infrastructure survey,and divided the measurement points into 7 categories according to combinations of influencing factors.The observation points were then measured at six typical periods between classes according to the travel activity patterns of students.The wind speed,air temperature,relative humidity,and heat index of each measurement point were recorded by walking at fixed points.Representative single-day measurement data in summer and spring were selected for analysis to study variations in the daytime wind environment index and thermal environment index.In addition,the roles of different combinations of factors in the design and optimization of the walking environment were judged.Some conclusions could be drawn:(1)The wind environment index of the walking environment is less affected by seasonal changes,while the thermal environment index is more affected by seasonal changes.The heat index,temperature,and relative humidity are much higher in summer than in spring.Hence,the key to improving the microclimate of walking environment is improvement of the thermal environment.(2)Among the different combinations of factors,a combination of three factors is better than a combination of two factors for improving the microclimate of the walking environment,because the combination of three factors can improve both the wind environment and thermal environment.(3)The wind and thermal environment indexes of the walking environment were t
