2008年，空气质量受到前所未有的关注。奥运会期间北京和其他6个奥运协办城市较好的空气质量，保证了第29届奥运会的成功。由此，我们能够因奥运会期间空气质量的改善而对未来的环境质量产生信心；同时，也感受到空气质量的走向扑朔迷离。本文的目的是阐述空气质量对民生的影响，并把如何了解空气质量走向的方法介绍给读者。
In 2008，air quality received greatest attention since the last 5 five years. On the one hand，increased confidence on air quality was reported both in Chinese and international media，due to the successful Olympic Games in Beijing and other 6 Olympic cities in China. On the other hand，there are different views about the air quality management measures taken during Olympic games （sustainability） and concerns about impacts of air pollution on the quality of life. This paper aims to 1） present an overview on the air quality in Chinese cities，mainly Beijing，Shanghai，and Guangzhou in 2008，2）introduce a structured framework （AQM） to assess air quality from general public point of view.
