摘　　要：治理寒地城市冬季产生的PM_(2.5)至关重要。本研究以大庆市西城区为研究对象,基于PM_(2.5)时空分布构建通风廊道。结果表明:(1)研究区域PM_(2.5)具有季节周期性,通常在秋季上升,冬季达到最高,春季之后下降;(2) PM_(2.5)浓度空间分布呈现出“东高西低”的特征;(3)对比通风廊道构建前后的风环境模拟结果,构建后西城区低风速区显著减少。It is very important to control the pollution caused by PM_(2.5) in the city in cold area.This paper takes Xicheng District of Daqing City as the study area,and constructs an urban ventilation corridor according to the temporal and spatial distribution of PM_(2.5).The results show that①the PM_(2.5) concentration in the study area has seasonal periodicity,and the concentration usually rise in autumn,reach the highest in winter,and decrease in spring.②The concentration distribution of PM_(2.5) presents the characteristics of“higher in the east and lower in the west”.③Comparing the wind environment simulation results before and after the construction of the ventilation corridor,the low wind speed area in Xicheng District is significantly reduced.
