Abstract

For contradiction and complexity of wind environment variables of coastal cities and difficulties in the quantitative research of urban spatial form, the multi-variable analysis technology is flexibly used to explore the feasible technical approach and coupling mechanism for the integration of coastal urban spatial form and the mesoscale wind environment system. The mechanism of influence of changes of coastal urban spatial form on wind environment is summarized, and the energy balance mode based on mesoscale wind environment nested with the urban boundary layer combining with the underlying surface of cities is studied, so as to make strategies for the response by urban spatial form to urban wind environment, simulate and analyze the response characteristics of urban heat island, local wind and pollution diffusion under different scenarios, and determine the feasible scheme of urban spatial form combined with demands for the development of social economy. With the combination of satellite remote sensing and ground monitoring, related parameters are collected, and simulated and calculated with CFD. After a conclusion is drawn through the multi-variable analysis the large wind tunnel laboratory model is used for verification. Further R&D can optimize the spatial form guidance system software for wind environment of coastal cities. This study will help to actively adjust urban wind environment through space guidance; provide reference for air pollution prevention and control, typhoon prevention and mitigation, urban energy saving and emission reduction and other hot research issues caused by the high-speed development of coastal cities in China; and respond to the government's call for the construction of new smart cities.
