Analysis And Diagnosis Of Air Quality Characteristics In Zhengzhou Based On Big Data Statistics

In January 2017,the national development and Reform Commission(State Development and Reform Commission)proposed to promote the construction of Zhengzhou as a national central city in the "reply to the support of Zhengzhou for the construction of the central city of the state".The relevant opinions call for the construction of a green low carbon sustainable development city.The construction of Zhengzhou is closely related to the overall situation of our province's social and economic development.Ensuring the good air quality and environment is the key to the construction of Zhengzhou.The study of Zhengzhou air quality data analysis and visualization can fully grasp the emission data of urban air pollution sources and the grade distribution of urban air quality,and can have a more comprehensive understanding and mastery of the factors affecting the urban air quality,so that the urban air pollution can be effectively controlled.This article has carried on the thorough research and the analysis to this,the main research work includes:(1)crawling the air quality data of Zhengzhou from December 2013 to February2018 through the Scrapy framework.(2)through the exploratory analysis of the air quality in Zhengzhou over the years,it is concluded that the overall air quality in Zhengzhou has been serious since four years ago.The main pollutants PM2.5/PM10/O3 in the atmosphere are obvious seasonal variations as well as air quality.O3 showed the opposite characteristics of other air pollutants,the most serious pollution in summer,followed by spring and autumn(slightly higher than autumn in spring)and lightest in winter.Quarterly analysis further confirms the seasonal change rule.(2)a large number of Zhengzhou air quality factors have been collected toconclude that the serious causes of air quality pollution in Zhengzhou are affected by geographical location,climate conditions and human activities(coal,transportation,dust,population and so on).The government pays more attention to the air quality.This paper makes a detailed contrast analysis on the influence of the government's air pollution control measures in time dimension,and concludes that the government's pollution control measures have improved the air quality in Zhengzhou to a certain extent,which is of great significance.(3)web site establishment,on the Microsoft Windows 10 platform,the phpstudy integration package is used as the development tool,and the hbuilder editor is used to complete the overall design and part of the functions of the green Zhengzhou website by using the development languages such as PHP,JS,HTML and CSS and Ajax interactive technology.It can be seen that the air quality in Zhengzhou has improved since 2017.At the same time,the measures of air pollution control in Zhengzhou are gradually strengthened,and the improvement of air quality in Zhengzhou is good.But we should be on the vigilance of increasingly serious ozone pollution.The research methods in this paper can also be applied to the research and analysis of air quality in other cities.
