盆地城市通风廊道营建方法研究--以西安市为例

摘要

The increasingly serious haze and heat island have gradually been an important factor disturbing social development and threatening people's physical and psychological health. Basin cities bear the brunt of this affection. During the anti-pollution and reduction of haze among the whole society, principles of landscape ecology, as one of the practical methods, have been employed to adjust cities' ecological layouts, connect ventilation corridors among cities and improve cities' microclimate environment. By concluding methods of building ventilation corridors in basin cities and combining advanced experience of designing and building ventilation corridors abroad, the paper researched the fresh air channel layout principle and width calculation methods. The paper proposes some planning ideas regarding the construction of ventilation corridors in the city of Xi'an, which is located in the Guanzhong Basin.%日趋严重的雾霾、热岛效应等气候现象逐渐成为困扰社会发展、威胁人们身心健康的重要原因，其中盆地城市首当其冲。在社会上下大力治污减霾举措中，通过调整城市生态及结构布局，打通城市通风廊道，改善城市微气候环境成为减霾、降温的可行方法之一。根据对盆地城市通风廊道营建方法的总结，结合国外盆地城市先进的通风廊道设计营建经验，探讨了通风廊道的布置原理和宽度的计算方法，并以西安市为例，提出了营建盆地城市通风廊道的规划与设计思路。
