Zhejiang Province City Of PM_2.5 In Time And Space Differentiation Characteristics And Its Relation With Other Gas Pollution Research

With the rapid development of China’s economy and urbanization. The number and scale of the city. The city also create many problems. For example, the urban ecological environment deterioration, traffic congestion, soil pollution, water pollution, air pollution, etc. Among them, the air pollution harm to people is more prominent. In recent years, more and more serious, atmospheric pollution haze, the increase in the ash haze days has seriously affected the people’s health and daily life. Air pollution is one of main pollutants PM_2.5. PM_2.5 particle size is very srtiall. PM_2.5 can enter the human respiratory system. PM_2.5 is called can go directly to the alveoli. Because PM_2.5 does great harm to human body and environment, so it is more and more attracted the attention of people, become a research hotspot at home and abroad.Zhejiang province is one of the most developed area in China, at the same time, the particulate matter pollution is very serious, also in zhejiang province is concomitant with the development of zhejiang economy air quality serious decline. In this paper, the data of 11 cities in zhejiang province （December 2,2013-December 31,2015）, the data of PM_2.5 and PM₁₀, SO₂, NO_x, CO concentration data, using Spss19.0 software now overweight status and characteristic value of the data statistics and analysis,Through mapping daily average concentrations of PM_2.5, the concentration of the monthly, seasonal concentration with the time change trend chart. Purpose is to grasp the overall PM_2.5 pollution in zhejiang province, the differences of PM_2.5 in time distribution;By using Arcgis, Geoda software from city to city in zhejiang province of PM_2.5 data to spatial autocorrelation analysis. Analysis of cities in different quarter global Moran’s I and local LISA figure. To explore the city between the interaction mechanism of PM_2.5, and cities of zhejiang province PM_2.5 agglomeration characteristics and specific concentration area. The purpose is to grasp the spatial differentiation characteristics of PM_2.5 in zhejiang province.PM_2.5 and other atmospheric pollutants (PM₁₀, SO₂, NO_x, CO, O₃) the relevance of research. Can let us know how the relationship between PM_2.5 and gas pollution, and the related degree. The purpose is to provide source of PM_2.5 analytic research resources.
