摘　　要：分析了社会经济因素对乌鲁木齐市冬季PM2.5重污染的影响,并选取国内其他城市进行比较研究.结果表明,乌鲁木齐市的城市发展规模、产业发展模式给环境空气质量尤其是PM2.5浓度的持续改善带来巨大压力:(1)人口规模持续增长,空间分布不合理;(2)中心城区机动车数量和密度不断增加,交通拥堵问题严重;(3)经济增长快速,但产业发展模式有待优化;(4)单位GDP能耗大,能源利用效率亟待提高.城市社会经济发展对大气环境质量有着根本的影响,根据大气环境承载力去定位和规划城市发展的方向和规模,是从源头上解决冬季PM2.5重污染问题的关键途径.According to data in Urumqi statistic year book,the influence of urbanization on atmospheric pollution are analyzed and compared with other cities.It is turned out that urban development scale and industrial development pattern exert severe stress on continuous improvement of air quality.The results show that firstly,population size grows fast and its spatial distribution is quite uneven.Secondly,the quantity and spatial density of vehicle are increasing leading to severe traffic jam.Thirdly,industrial developing pattern still need to optimize.Finally,energy use efficiency is below the average level and energy structure need to adjust.Urbanization has a fundamental influence on air quality,so the process and scale of urban social-economic development should be positioned and planned by the atmospheric environmental capacity to solve the problem of air pollution fundamentally.
