【摘要】 以在城市规划建设中提高空间布局的气候适宜性、实现良好的自然通风为出发点，构建了一套覆盖城市—小区尺度的自然通风规划技术方法，在石家庄都市区规划中进行应用。其中城市尺度利用气象观测、卫星遥感、现状建筑矢量数据，综合气象数值模拟、RS反演与GIS分析，进行背景风环境评估、热环境评估和通风环境评估，并利用城市建设对气候影响程度不同，将研究区分为5类气候空间。在以上研究分析的基础上，形成了“6+13”多级通风廊道规划方案，并提出应依据城市气候分析图采取不同开发策略。小区尺度则采用CFD模拟及观测实验，对典型街区微气候环境进行模拟分析，评估不同建筑布局、密度对通风环境的影响。结果表明：主导风向上游方向建筑物越少、密度越小，越有利于通风。风速衰减等级随建筑密度升高而增加，街区内垂直于风向且建筑密度较高的建筑群，挡风效果最为明显。更多还原

【Abstract】 Based on the research of urban construction and ventilation environment, a natural ventilation planning technology, covering both the city and the community scale, has been proposed and applied in Shijiazhuang City in China to improve the natural ventilation capacity in urban planning and construction.Various types of data were applied in it, including meteorological observation data, satellite remote sensing data, and current building site vector data.Furthermore, combinations of technologies were considered, including the meteorological numerical simulation technology, remote sensing(RS) retrieval, Geographic Information System(GIS) superposition analysis technology, Computational Fluid Dynamic(CFD) numerical simulation technology, and observational experimental analyses technology.According to the analyses of background wind environment and the evaluation of heat island intensity and ventilation potential, the study area is divided into five types of climate zones.On the basis of the above research, 6 first-class ventilation corridors and 13 secondary ventilation corridors are constructed.Subsequently, it is proposed that different development strategies should be adopted according to the climate zones.The community scale planning is realized through the microclimate simulation of typical blocks in order to evaluate the impact of different building layouts and densities on the ventilation environment.The results reveal that areas, located upstream of the dominant wind with low-density buildings, have a good ventilation environment.The higher the building density, the more wind speed decreases.Buildings that are perpendicular to the wind direction and have higher building density have the most obvious wind-shielding effect.更多还原
