城市风环境关系到居民的身体健康与舒适,污染物的扩散与空气自净,建筑节能减排等多方面问题。本研究在中观层面对风环境进行分析,基于空间分析的地表粗糙度及最小成本路径法,建立了一套模拟预测中观尺度区域城市的风廊道分布的评估方法,并结合北京新机场项目进行了实际应用。该方法讨论了城市型态及布局对于风廊道规划设计的影响,实现了风环境与城市规划的有机结合,对未来城乡规划等中观尺度的规划起到示范作用。
Urban wind environment is related to the health and comfort of residents, the proliferation of pollutants and self-purification of air, building energy-saving emission reduction and many other issues. Based on the analysis of the surface roughness and the least-cost path method, a set of assessment methods to simulate the distribution of wind-corridor in meso-scale urban areas was established. In combination with the new airport of Beijing The project has been put into practical application. This method discusses the influence of urban pattern and layout on the planning of wind tunnels, realizes the organic combination of wind environment and urban planning, and plays an exemplary role in the planning of medium-sized urban and rural planning in the future.
