Research on the Influence of Ground Surface on Wind Environment in Shanghai Urban Squares

摘要

In order to reveal correlation between ground surface of urban squares and wind environment, the wind speed and wind direction of 20 plots were monitored during summer and winter in Shanghai Nation Anthem Square (NA square), Shanghai Knowledge and Innovation Community square (KIC square) and Shanghai Haisu Greenbelt Square (HSG square). The variations of wind speed and wind direction with different elevation, material, slope, slope form, topographic feature and aspect were surveyed. The difference of air flow in a variety of squares’ ground surface in summer and winter were analyzed. Furthermore, the design strategies of microclimate regulation were proposed for future squares planning with the seasonal preferences of wind environment.
