Abstract

ABSTRACT: Recently, air pollution has attracted a substantial amount of attention in China, which can be influenced by a variety of factors, but the association between air pollution and human activity is not quite clear. Based on real-time online data (January 1, 2014, to December 31, 2014) of air pollution and meteorology reported by official sites, and demographic, economic, and environmental reform data in a statistical yearbook, the influences of meteorological factors (temperature, relative humidity, precipitation intensity, and wind force) and human activities on PM2.5 pollution were explored. After correlation analysis, logistic regression analysis, and a nonparametric test, weak negative correlations between temperature and PM2.5 pollution were found. In most cases, festival and morning peak hours were protection and risk factors of PM2.5 pollution, respectively. In addition, government actions, such as an afforestation project and increasing financial expenditure for energy saving and environmental protection, could greatly contribute to alleviating pollution of PM2.5 . The findings could help officials formulate effective laws and regulations, and then PM2.5 pollution related to the pattern of human activity would be ameliorated. Implications : Most of the time, festival and morning peak hours are protection and risk factors for PM2.5 pollution, respectively. Increasing the percentage of afforestation area and financial expenditure for energy saving and environmental protection could significantly reduce PM2.5 pollution. The findings can help officials formulate effective laws and regulations, and then PM2.5 pollution related to the pattern of human activity, especially government action, will be ameliorated.
