摘　　要：以合肥市主城区为例,采用气象观测数据、卫星遥感数据、地理信息等数据,通过计算天空开阔度、地表粗糙度等城市生态参数,对合肥市主城区通风潜力进行等级划分,并对通风廊道建设提出建议。结果表明,位于合肥市主城区的合肥经济技术开发区和双凤开发区热岛效应较严重,中心区域天空开阔度较差,大部分区域在0.5以下,南淝河沿岸地表粗糙度较小,但其两侧地表粗糙度较大。大部分区域地表通风潜力一般,东南侧靠近巢湖区域和南淝河沿岸通风潜力较高,建筑区域与西北侧区域通风潜力较差。结合合肥市主城区的风向玫瑰图、城市空间热环境分析,构建了四纵两横的六条通风廊道。Taking the main urban area of Hefei as an example,this paper uses meteorological observation data,satellite remote sensing data,geographic information data and other data to classify the ventilation potential of the main urban area of Hefei by calculating urban ecological parameters such as sky openness and surface roughness,and then we give suggestions on the construction of ventilation corridors.The results show that the heat island effect is serious in Hefei Economic and Technological Development Zone and Shuangfeng Development Zone.The sky view factor in the central area is poor with most areas below 0.5,and the surface roughness along the South Feihe River is lower,but the surface roughness on both sides is higher.The surface ventilation potential is moderate in most area of the region,except the higher ventilation potential in the southeast area near Chaohu Lake and the coast of the South Feihe River.The ventilation potential in the building area and the northwest area of this region is poor.Based on the wind direction rose diagram and the analysis of urban space thermal environment,we construct six ventilation corridors with four longitudinal and two horizontal lines preliminarily constructed.
