Characteristics of haze pollution in Beijing-Tianjin-Hebei region of China

Haze pollution has become one of the most serious environmental problems in China, especially in Beijing-Tianjin-Hebei region. Chinese government has issued a haze control policy in 2013, which aims to alleviate haze pollution through reducing emission of air pollutants. However, there is a doubt whether the haze concentration target can be achieved through implementation of the air pollutants emission reduction plan. This paper focused upon the numerical relationship between haze concentration and air pollutants emission based on data analysis approach in the Beijing-Tianjin-Hebei region. The haze control policy in the Beijing-Tianjin-Hebei region should shift from concentration target to emission control target. Tianjin and Hebei should reduce much more air pollutants emission. Beijing should consider a more reasonable concentration target and emission control plan for joint-regional efforts.
