A Study on the Model for Heating Influence on PM_(2.5) Emission in Beijing, China

摘要

PM_(2.5) concentration in Beijing China has become a focus for government and common people. In this paper, the author, taking PM_(2.5) in Beijing as research object, establishes a model of heating influence on PM_(2.5) emission. Data about the city's boiler number, distribution, fuel consumption as well as rural fuel consumption have been obtained through questionnaire. With the adoption of coefficients for producing and emitting pollutants, influence of heating factors in Beijing on PM_(2.5) concentration is evaluated quantitatively. High accuracy of the model in the paper has been proved through comparison with data of 2014 Beijing PM_(2.5) concentration monitored by Chinese Ministry of Environmental Protection. According to evaluation result 10.9, heating contributes to 13.7% of PM_(2.5) emission in Beijing, 9.9% and 3.8% from the six urban districts and rural areas respectively. It has been suggested that measures including decreasing heating temperature should be adopted to alleviate PM_(2.5) pollutions in Beijing.
