DOMESTIC AND INTERNATIONAL COMPARATIVE STATISTICAL STUDY OF AIR QUALITY INDEX

Li Yajie, Li Xiaofei and Lu Suting

ABSTRACT: Through the comparative study of domestic and international air quality index standards, including the development of air quality standards, pollutant projects, air quality index calculation methods and grading method, the existing problems of China’s air quality index standard are found. The air quality indexes of major cities in China are calculated by the interpolation method, and then the spatial distribution of environmental pollution is studied. It was concluded that China’s air quality index standards has essentially been brought in line with international standards, while the air quality of economically developed Beijing-Tianjin-Tangshan region is poor and must be harnessed.
