Research On The Spatial Distribution Of Inhalable Particles PM₁₀ And The Factors Which Influence The Distribution

Suspended particles in the air has become an important factor affecting the air quality. In recent years, China’s air pollution is serious, the air quality is worrying. The frequent arrival of haze weather leads to the reduced visibility, incidence of respiratory diseases increased. In order to deal with air pollution, air pollution detection platform for real-time reports to the city every day, to let people have a clear understanding of serious deterioration of air quality in form, in order to gather the attention from more aspects. In order to get a better understanding of inhalable particles in the atmosphere pollution situation in China, understand the characteristics of spatial distribution, influence factors of inhalable particles, this article has carried on the analysis. The empirical analysis is divided into two parts, the first part is to use the method of spatial statistics, taking into account the factors of location, do some analysis about the 31 city of China’s provincial capital city and the municipalities directly under the central government.Through the global Moran index derived Atmospheric Respirable Particles into space is self distribution characteristics, namely high concentration area and high concentration area tends to spatial agglomeration, low concentration and low concentration of regional trend area on the spatial agglomeration, and the temporal change trend and made further research. Making use of the method of local spatial statistics, the local Moran exponent obtained distribution characteristics of each city and the surrounding city in this variable space, is the serious pollution of the Beijing Tianjin Hebei region made special note. The second part is the use of the method of grey correlation analysis, the per capita GDP, industrial dust emissions, green coverage rate, city gas supply, the number of cars and other factors, through the calculation of the respective correlation with the concentration of each index to reflect the influence degree on particle impact, the provincial capital City and the municipalities directly under the central government the city is divided into two pieces, with the State encourages public traffic, and reduce private car travel two calls, especially private cars to affect inhalable particles, provides the theoretical basis for this call. According to the research conclusions and puts forward the corresponding improvement of the atmospheric environment suggestion.
