Spatial analysis of haze-fog pollution in China

Haze-fog pollution has been one of the major atmospheric pollution problems in China. This study is aimed at understanding spatial distribution and spatial correlation of haze-fog pollution in China from 2001 to 2010 using exploratory spatial data analysis technique. The results show that spatial distribution of haze-fog pollution is not changed obviously in the 10 years, and the most serious polluted region is distributed in Beijing-Tianjin-Hebei region. The values of global Moran's I vary from 0.4066 to 0.4842, which indicates that haze-fog pollution is not distributed randomly, but has spatial agglomeration effects. The High-High agglomeration type is mainly distributed in central China, which contains 15, 14, 14, and 13 regions for the years of 2001, 2004, 2007, and 2010, respectively, while the Low-Low agglomeration type is concentrated in western and eastern China, which contains 11, 10, 10, and 8 regions for the years of 2001, 2004, 2007, and 2010, respectively. The results should provide policy guidance for public authorities to control haze-fog pollution. Further researches are still needed because of the complexity of haze-fog pollution and variety of influence factors.Research Planning Foundation in Humanities and Social Sciences of the Ministry of Education of China [13YJAZH044]; National Science Foundation of China [61173052]; Guangdong Soft Science Item [2013B070206002]SSCIARTICLEtangdengli_2008@163.com6-7726-7402
