摘　　要：目的综合解析湿热风缓地区传统聚落空间对风环境的影响效应。方法基于田野调查,利用CFD软件对聚落整体和聚落建筑的风环境进行模拟分析;选取凤台村3栋典型三合院,分析不同长高比和宽高比对聚落空间风环境的影响。结果在聚落整体街巷结构与建筑密度的综合影响下,凤台村冬季的聚落空间风速总体呈东北高、西南低的分布特征,夏季的聚落空间风速呈由村口向东北方向的递增规律,聚落整体风环境良好;模拟分析得出聚落建筑吊脚干栏的最佳空间形制:宽高比为6,长高比为7.2。结论聚落空间风环境受到街巷结构与季节主导风、建筑形态与密度的综合影响,传统聚落空间形制体现了对区域风环境的高效适应,以及对局部微气候的有效利用,建议在进行聚落保护规划与地域建筑设计时应遵循此空间形制特征。An integrated analysis of the impact of traditional settlement spaces in regions characterized by a mild and humid climate on the wind environment is conducted.Field investigations are utilized alongside Computational Fluid Dynamics(CFD)software to simulate and analyze the wind environment of the overall settlement and individual buildings within the settlement.Specifically,three typical courtyard houses in Fengtai Village are selected for analysis,exploring the influence of different length-to-height and width-to-height ratios on the wind environment of the settlement.Considering the combined effects of the overall street and alley structure and building density within the settlement,the winter wind speed in Fengtai Village exhibits a general distribution pattern of being higher in the northeast and lower in the southwest,while in summer,the wind speed within the settlement shows an increasing trend from the village entrance towards the northeast direction,indicating a generally favorable wind environment within the settlement.Simulation analysis yields the optimal spatial configuration for the courtyard houses,with a width-to-height ratio of 6 and a length-to-height ratio of 7.2.The wind environment within the settlement is influenced by a combination of street and alley structures,prevailing seasonal winds,and building morphology and density.Traditional settlement spatial configurations demonstrate efficient adaptation to regional wind environments and effective utilization of local microclimate conditions.It is recommended that this spatial shape should be followed in the future settlement protection planning and regional architectural design to ensure optimal settlement environments.
