Vegetation is regarded as one of the most effective methods to improve the outdoor microclimate and pedestrian thermal comfort. Throughout numerical simulation experiments, the plant communities’ effect on outdoor wind environment and the relationship between them have been studied. The conclusions could be drawn as follows: 1) Ginkgo biloba community, Sophora japonica community and Magnolia denudata community have more obvious attenuation effect of wind velocity. Communities have poorer attenuation effect of wind velocity because of smaller size and crown diameter. 2) The reduction ratio of upstream wind velocity increases accompanying canopy closure, leaf area index, structure and height of dominant species of plant community.

Through FLUENT numerical simulation, this paper is aimed on studying the influence of outdoor wind environment on indoor environment. We found that building height, building layout format and opening format in the wall are significant impacted on indoor natural ventilation. At the three-fourth height of building, if the building layout and housing opening is stagger, it can get high-quality indoor natural ventilation and more evenly indoor wind field.
