Time And Space Distribution Characte--Ristics Of The Severe Fog And Haze Of China And The Influence Factor Analysis

In recent years, the frequency of fog and haze is improving.This is not only a serious threat for daily life and health,but also is a huge loss to economic.Therefore,this article discusses the time and space distribution charateristics of serious haze,and analysis the interaction influence of 31 provinces and the influence of energy consumption、economic and greeing.It can provide reference for government to control or prevent haze.The method of the paper include Kriging interpolation method,System clustering analysis,Spatial autocorrelation,Grey correlation analysis.The data include API,Meteorological site data,The concentration of 2.5.The main research contents and results as follows1.The distribution of haze and fog is differenct in time and space base on the use of statistical methods.Fog,haze and 2.5.are mainly distributed in beijng-tianjin-hebei,Shandong,northwest of north of China,the southeastern of Sichuan and Chongqing. Fog and haze distribution has obvious seasonal.There are more in winter and fall than in summer and spring.The distribution of API is regional differences,for example,the concentration of 2 and 10 in the northern city is higher than the southern,and the value of API will change as the seasons change.2.Using the spatial autocorrelation between China’s 31 provinces of 2.5 from the perspective of regional interaction space. The results showed that the haze pollution is significantly positively related to the space.The main pollution zones is beijing-tianjin-hebei,Yangtze river delta region,and as time gose by, the positive correlation index is rising.3.Mainly using the cluster analysis for China’s regional division. Clustering analysis of API of recent years on the base of the positive correlation of 2.5 distribution.finally, China is divided into five areas.4. Research the pollution area on the base of division of China,.Analysis from the aspects of the development of the city and then research the influence of social and economic activities on haze in tianjin using the grey correlation. Results show that there is close contact between human activity and haze. Especially, the urban population, energy combustion, urban greening, environmental investment and industrial emissions haze of main pollutant and the influence factors, such as correlation degree is bigger.
