Study on the Application of Ventilation Corridor Planning in Urban New Area --A Case Study of Xixian New Area

The cause of urban heat island effect is closely related to urban activities, urban construction environment and landscape. The planning of urban ventilation corridor in Urban New District focuses on the optimization of the wind environment, not only can effectively improve the quality of living environment, but also can conducive to the realization of energy-saving emission reduction. According to the urban wind air flow movement and urban underlying surface characteristics, the paper takes Xixian New Area as an example, according to the climate in cold regions divided different ecological and climatic zoning, uses CFD simulation method, and determines the city through the main control factors of the location and number of wind corridor, purporting and corridor on the windward side of density control in urban ecology and open space layout, in order to providing a reference for future planning and construction has a good climate and environment in new city.
