基于德国城市通风廊道的构建理论,分析了杭州主城区风环境基本特征,根据杭州绿地系统规划内容和2015年主城区地表温度反演图,确定了杭州主城区通风廊道的补偿空间和作用空间,构建主城区内“三横两纵”五条潜在通风廊道,缓解了城市热岛效应和空气污染问题。 Based on the construction theory of the urban ventilation corridor in Germany, the basic characteristics of the wind environment in the main urban area of ​​Hangzhou are analyzed. According to the planning contents of Hangzhou green space system and the surface temperature inversion map of the main urban area in 2015, the compensation space and the role of the ventilation corridor in the main urban area of ​​Hangzhou are determined Space to build five main potential ventilation corridors in the main urban area to ease the urban heat island effect and air pollution.
