Analysis of the causes of frequent hazy weather in the Beijing-Tianjin-Hebei region

In China, hazy weather is most serious in the Beijing-Tianjin-Hebei region. Therefore, how to prevent the hazy weather in this region has become an important task of China’s current environmental management. However, in order to prevent the hazy weather in the Beijing-Tianjin-Hebei region, the priority is to analyze the causes of its hazy weather. The paper comprehensively analyzes the causes of the hazy weather in the Beijing-Tianjin-Hebei region with literature analysis, field research and other methods and gives the main causes. These include: i) there is a large number of civilian vehicles as well as large emissions of automobile exhaust, ii) economic development mode is simple and extensive, iii) highly-polluted secondary industry accounts for a large proportion, iv) industrial distribution and regional self-purification capacity do not match, v) regional industrial planning is unreasonable, etc. It is hoped that it can be helpful for China’s prevention and control of regional hazy weather. © 2016, UK Simulation Society.
