Coupling Numerical Simulation and Field Experiment to Optimize Vegetation Arrangement for Pleasant Outdoor Wind Environment in Residential District

摘要

Combining with field experiments in Ivy Town residential area, numerical simulation of the influences of vegetation on outdoor wind environment with SPOTE (Simulation Platform for Outdoor Thermal Environment) was carried out for comparison in the study. The conclusions were drawn as follows: 1) the wind velocity with and without vegetation was compared both in winter and summer; the simulation results would help us determine which vegetation to plant in green space; 2) after supplanting the status deciduous vegetation into evergreen one, the actual wind velocity increased to a much extent in areas with adjusting vegetation than areas with status vegetation, with an increase by 64.7% in winter; 3) by adjusting arrangement and types of vegetation in the regions where the wind environment was unpleasant for pedestrian thermal comfort both in winter and summer, the pedestrian-level wind velocity could be obviously improved through the simulation and comparison.
