| 为了提高环境的舒适性，节约能源
资源、减轻环境污染，特别是为了避免城市雾
霾天气，贵阳市政府自2013年10月起组织开展
了贵阳市通风道专项规划。该规划研究项目，
从贵阳市自然环境、气象条件等方面出发，
利用中尺度气象模拟模型WRF（Weather &
Research Forecasting Model）对贵阳市城区
范围内风环境进行模拟，并对贵阳市城市气
候现状进行了分析。在此基础上，根据贵阳
市原有绿地、水系、路网等自然资源和条件，
以“保外围、疏通道、控建设”为原则，在贵
阳市全市范围内，规划设计了一级通风道6
条、二级通风道16条，以及三级通风道3 0
条，为贵阳市“通风、换气”。模拟结果显示，
规划通风道后，贵阳市冬季平均风速提高了
近8%，夏季平均风速提高了近6%，贵阳市老
城区冬季平均风速提高了近12%，夏季平均
风速提高了近9%，此城市通风道规划方案非
常有效地改善了贵阳市的城市通风条件。 |

| Abstract: |
| To improve the urban environment comfort, save energy consumption, and reduce the
air pollutant especially the dusts and haze in the air, the city council of Guiyang has organized a
special project of urban ventilation corridor planning and design in Guiyang since October, 2013.
Based on the environment, natural resources, and weather condition of Guiyang, the Weather &
Research Forecasting model of WRF is applied to this project to find out the areas and locations
with poor wind environment in Guiyang. According to the principles of urban ventilation
corridor planning of Guiyang, which are reserving the green space, dredging the channels, and
controlling the development, the planners have designed six first-level corridors, 16 second-level
corridors, and 30 third-level corridors basing on the existing green area, water system, and traffic
network of Guiyang. The simulation results of WRF illustrate that due to the planning of urban
ventilation corridor, the winter average wind speed of Guiyang increases 8%, summer average
wind speed of Guiyang increases 6%, winter average wind speed of the central city of Guiyang
increases 12%, and summer average wind speed of central city of Guiyang increases 9%. |
