Abstract

Vegetation plays a key role in improving wind environment of residential districts, and is helpful for creating a comfortable and beautiful living environment. The optimal design of vegetation for wind environment improvement in winter was investigated by carrying out field experiments in Heqingyuan residential area in Beijing, and after that, numerical simulation with SPOTE (simulation platform for outdoor thermal environment) experiments for outdoor thermal environment of vegetation was adopted for comparison. The conclusions were summarized as follows: 1) By comparing the experimental data with simulation results, it could be concluded that the wind field simulated was consistent with the actual wind field, and the flow distribution impacted by vegetation could be accurately reflected; 2) The wind velocity with vegetation was lower than that without vegetation, and the wind velocity was reduced by 46%; 3) By adjusting arrangement and types of vegetation in the regions with excessively large wind velocity, the pedestrian-level wind velocity could be obviously improved through the simulation and comparison.
