| 摘 要： | 高密度街区的微气候对居民的体力活动、空气污染暴露甚至健康都具有一定的影响。以南京莱迪广场为例,采用CFD软件模拟并分析了南京莱迪广场夏季热环境、风环境状况。结合广场夏季微气候状况,从广场与周边建筑、活动设施位置、植物种植设计、铺装设计、水景设置五个方面提出优化城市广场风热环境的设计策略,期望为城市设计师在广场设计方面提供理论基础以创造更舒适的城市户外空间。

| Abstract: | The microclimate of high-density neighborhoods has a certain impact on physical activity,air pollution exposure and even health of residents.Taking Laidi square as an example,CFD software was used to simulate and analyze the thermal and wind environment of Laidi square in Nanjing in the summer.Combined with the micro-climate of the square in summer,this paper proposes the design strategy of optimizing the wind and heat environment of the square from five aspects:the surrounding buildings,the location of activity facilities,the plant design,the material of pavement,and the setting of water,hoping to provide a theoretical basis for urban designers to create more comfortable urban outdoor space during the design of the square. |
