摘　　要：不同历史背景和规划理念下形成一个城市的不同道路肌理形态,不同的道路肌理形态又影响作用于城市微气候因子而形成了独特的局地微气候.以上海老城厢、古北社区、安亭新镇和新江湾城4个城市肌理为研究对象,利用ENVI-met4.3模拟软件对4个区域的微气候进行模拟,进而从中观与微观方面对比分析城市道路肌理的微气候状况.在中观层面分析了路幅宽度、走向、间距和连通性与气候环境的关联性;在微观尺度分析了道路的贴线率、高宽比(H/W)和天空开阔度(SVF)指标对道路的微气候因子分布特征的影响.这一尺度的微气候特征比较分析研究对城市设计及空间形态优化方面将提供气候适应性发展的有益建议.Different historical backgrounds and planning ideas result in different road fabrics for a city.Road fabric patterns affect urban microclimate factors and form a unique local microclimate.In this paper,we studied the road fabric of four"city"areas in Shanghai(i.e.,the old downtown area,Gubei international community,Anting new town,and new Jiangwan town)by simulating the microclimate of the four research areas using ENVI-met4.3 software;we then used the data to compare the microclimate status of urban fabric at the medium and micro levels.At the medium level,the relationship between width,orientation,spacing,connectivity,and the climate environment was analyzed.At the micro level,the effects of Near-line Rate,Height to Wide ratio(H/W)and Sky View Factor(SVF)on the distribution characteristics of microclimate factors in roads were analyzed.The comparative analysis of microclimate characteristics at the"city"scale provides useful insights for urban climate adaptability in urban design projects and spatial morphology optimization in future urbanization development.
