【摘要】：城市化快速发展带来城区下垫面类型与格局的改变,进而影响着城市环境健康与微气候,这在中国夏季高温干燥的京津冀地区尤为突出。研究以河北省隆尧县为例,基于CFD软件对城区景观不同下垫面对夏季微气候的影响开展数值模拟研究。结果表明:景观下垫面的类型、布局方案及绿地率等因素都对夏季微气候产生影响。在此基础上,研究提出在景观下垫面类型选择、布局方式与绿量方面的设计优化策略,以期对城市设计与景观规划设计提供支撑。
[Abstract]:The rapid development of urbanization has brought about the change of the type and pattern of the underlying surface of the urban area, thus affecting the urban environmental health and microclimate, especially in the high temperature and dry area of Beijing, Tianjin and Hebei in summer in China. Taking Longyao County of Hebei Province as an example, a numerical simulation study was carried out on the effect of different underlay of urban landscape on summer microclimate based on CFD software. The results showed that the type of underlying surface, layout scheme and green space rate all affected the microclimate in summer. On the basis of this, the paper puts forward the design optimization strategy in the aspects of the choice of landscape underlying surface type, layout mode and green quantity, in order to provide support for urban design and landscape planning design.
