摘要
作为城市空间形态的重要组成要素,建筑群高度表现出强烈的差异性,本文将国内外相关研究根据技术手段进行分类,归纳建筑群高度差异性影响对气流流动特性与污染物输运特性的影响.总结分析表明建筑群高度存在变化使水平流动衰减,并加剧竖向湍动交换,并且整个城市冠层内部的湍动状态与污染物浓度将发生显著变化,并探讨了未来研究的方向,利用遥感、GIS数据进行建筑高度信息的快速提取和测算,能够更好的反映实际城市建筑群高度分布的复杂性,具有更大的发展空间.
As an important element in the form of urban space,the heights of buildings show great differences.This paper classified the relevant domestic and foreign studies according to the technical methods,and summarized the influences of height variability of urban buildings on the airflow flow and pollutant transport characteristics. The summary and analysis show that the height variability of buildings attenuates the horizontal flow and intensifies the exchange of vertical turbulence, bringing significant changes to the turbulent characteristics and pollutant concentration within the urban canopy. The research direction was further discussed. The use of remote sensing technology and GIS data for the rapid extraction and calculation of building height information can better reflect the complexity of the height variability of urban buildings,which is of great research potential.
