In order to study the role of stereoscopic greening in improving the microclimate,four representative three-dimensional green buildings in Chongqing are selected for microclimate measurement and analysis,and the factors such as the greening orientation,distance from the outer wall,and leaf area index are compared to the cooling and humidification of the green wall.The measured results show that the stereoscopic greening with a surface width of less than 30 m can reduce the air temperature by about 0.7℃and increase the relative air humidity by about 15％.The stereoscopic greening with a surface width of more than 30 m can achieve a cooling effect of 1.5 to 3 ℃.The three-dimensional greenery facing east-west is about 0.9 ℃ cooler than the one facing north-south,and the air humidity is increased by about 1.5％.The leaf area index has a great influence on the cooling and humidifying effect of stereoscopic greening.The leaf area index increases by 0.40,the air temperature decreases by about 0.6 ℃,and the air humidity increases by about 3％.The stereoscopic greening has a wide range of influences on the microclimate.The research results confirm that the implementation of stereoscopic greening at the block scale can adjust the urban microclimate and improve the urban thermal environment.
