中文摘要: “大气十条”实施以来，全国城市 PM2.5 浓度呈下降趋势，预期能够实现国家规
定的 2017 年空气质量改善目标。若按现有力度措施，北京市 2017 年 PM2.5浓度达到年均
值 60 μg/m3 左右的目标难以实现，同时臭氧（O3）污染迅速抬头。未来两年必须下决心采取
超常规措施破解北京大气污染防治中的若干难点问题，才能突破大气污染治理瓶颈，达到
预定目标。

Abstract:In most China cities, fine particulate matter (PM2.5) concentration has decreased after implementation of Air Pollution Prevention and
Control Action Plan in past three years, and the goals of overall national air quality improvement listed in the plan is expected to be achieved
by 2017. However, the specific goal of that PM2.5 annual concentration in Beijing shall be controlled below 60 micrograms per cubic meter by
2017 is difficult to be accomplished. Meanwhile, ozone (O3) pollution is emerging quickly in Beijing. Regarding the present situation in air
pollution in Beijing, a number of extraordinary measures of air pollution prevention and control must be carried out immediately during the
next two years.
