摘　　要：当前城市天际线的营造往往只关注视觉美感,而忽略了构成天际线的建筑群布局对城市室外风环境造成的影响。文章利用计算流体力学模拟软件Phoenics,从天际线的空间层次来分析陆家嘴金融中心区的建筑群布局。首次提出将天际线空间层次系数作为量化方式,通过对其冬夏两季室外平均风速比数据进行分析,探究天际线空间层次与城市室外风环境间的关系。结果表明,天际线空间层次与冬夏两季建筑群室外风环境存在截然不同的变化趋势,天际线空间层次系数与该段天际线所对应的建筑群区域的平均风速比之间存在明确的函数关系。该结论可为营造富有美感的天际线空间层次,且具有舒适城市风环境的城市设计工作提供新的视角。The current urban skyline is often created by focusing on the visual aesthetics,but ignoring the impact of the building group layout on the outdoor wind environment of the city.This paper uses the computational fluid dynamics simulation software Phoenics to analyze the building group layout of Lujiazui financial center area from the spatial level of skyline.The skyline level coefficient is proposed as a quantification method,and the relationship between the skyline level and the outdoor wind environment of the city is investigated by analyzing the ratio of the skyline level to the average outdoor wind speed in winter and summer.The results show that there are different trends between the spatial level of skyline and the outdoor wind environment of the building complex in winter and summer,and there is a clear functional relationship between the skyline level coefficient and the average wind speed ratio of the building complex area corresponding to this section of skyline.The findings may provide a new perspective for the urban design work to create aesthetic skyline levels with comfortable urban wind environment.
