Description
Summary:The consumption of fossil fuels has resulted in the increasing environmental pressure and a series of environmental pollution problems. Taking four Chinese cities (Beijing, Tianjin, Shanghai and Chongqing) as examples, the reasons of fog and haze caused by multi-factor coupling were studied in this paper. Firstly, the contribution of four factors (including building completed area, thermal power generation, gross industrial output value and wind speed) to fog and haze in Tianjin was analyzed, and then these four cities were compared to explore the impact of the same factor on fog and haze in different regions. Secondly, the functional relationships between these four factors and air quality index (AQI) were obtained based on statistical data, and a sensitivity analysis was carried out to get the dominant factor of fog and haze in these four cities. Finally, the corresponding policy recommendations were given based on different dominant factors of these four cities. •The influence of four factors in different regions on AQI is explore.•The functional relationship between AQI and four factors is obtained.•The leading factors affecting AQI are obtained through sensitivity analysis.•Give the corresponding policy suggestions according to the leading factors.
