Abstract
Green space offers great benefits to urban environment quality. There has been lots of research on urban green space planning and landscape ecological effect, however, few quantitative work has been carried out on its microclimate impact. The current relevant studies have been more focused on greening quantity, with less concern for greening structure. Evaluation of wind field, thermal comfort and air quality is also important for microclimate research as well as thermal environment. ENVI-met model is set up and microclimate is evaluated for temperature, wind speed, thermal comfort and concentration of PM10. The results show that eco-greening plot ratio are positively correlated with day-time cooling effects and thermal comfort of green land, and negatively correlated with wind speed and PM10 concentration. Landscape diversity index of tree patch in home-site greenbelt is negatively correlated with cooling effects and particle deposition, while positively correlated with wind speed.
