Abstract
Rapid urbanization process has brought about a global challenge in the ecological environment, such as air pollution and “Urban Heat Island Effect”. On one side, climate is one of the most important elements that maintains human survival and production, and also the key factor of spatial morphology. On the other side, different spatial forms also affect local microclimate. Early in 1968, the WMO organized the first international urban climate conference to specially study the influences of urban planning and design that make on the climate. It is indispensable to seek for optimized approaches to urban spatial form design for better environment. Wind environment, a part of urban climate, plays a critical role in improving urban spatial environment. Strategies for better wind environment and constructions of urban ventilation corridor can effectively relieve air pollution and accumulated heat. Countries like Germany and Japan early studied macroscopic ventilation corridor planning, and combined it with urban master plan. Some urban spatial forms, such as density, height, volume rate, etc. have been further studied to seek for specific optimization. While most studies tend to get a qualitative control but have poor implementation. Quantitative studies are essential to be done. In this study, we will first make a simple introduction about the overall background wind environment in Changzhou. Then we will construct three-level ventilation corridors. Multi-dimension spatial morphology factors will be respectively extracted to simulate through CFD. Finally, several specific optimization approaches will be proposed for future urban design.
