【摘要】：城市化快速發(fā)展帶來城區(qū)下墊面類型與格局的改變,進而影響著城市環(huán)境健康與微氣候,這在中國夏季高溫干燥的京津冀地區(qū)尤為突出。研究以河北省隆堯縣為例,基于CFD軟件對城區(qū)景觀不同下墊面對夏季微氣候的影響開展數(shù)值模擬研究。結(jié)果表明:景觀下墊面的類型、布局方案及綠地率等因素都對夏季微氣候產(chǎn)生影響。在此基礎上,研究提出在景觀下墊面類型選擇、布局方式與綠量方面的設計優(yōu)化策略,以期對城市設計與景觀規(guī)劃設計提供支撐。
[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.
