Research On The Distribution And Relationship Between Urban Heat Island And Concentration Distribution Of PM2.5 And PM10

The process of urbanization and industrialization is speeding up increasingly.At the same time,human factors have more obvious influences on The climate and air quality,and the question on urban heat island effect has kept coming up.Mineral fuel ?s burning can not only make the enormous amount of heat has released but also make Atmospheric pollutant gas in the process of industrial manufacture.In all kinds of Pollution emissions,PM2.5 and PM10 had made a big influence on urban atmosphere quality.While the two pollutions has an impact on urban air temperature and distribution of the urban heat island by changing Atmospheric transport process and Atmospheric vertical motion.Pollutions‘ influence on urban heat island is deferent because of deferent landforms and location of the pollution source.Studying the relationship among PM2.5,PM10 and urban heat island has important significance in understanding the cause of the urban heat island and contaminant transport mechanism of the pollution,etc.And it can make an auxiliary decision in the urban layout,and factory location,atmospheric pollution control.The relationship between urban heat island and concentration distribution of PM2.5 and PM10 was studied In this paper By using environmental monitoring data and weather data of Beijing In combination with remote sensing data.The research content mainly includes following several aspects:(1)The major air pollutants in Beijing was studied and the different types of different pollutants were discussed month by month or quarter by quarter while the change of the pollutant in one day was analyzed.Research on the spatial distribution of PM2.5 and PM10 concentration was involved.The pollution hierarchies were made according to the standard of air quality standards for PM2.5 and PM10 among pollution areas in Beijing.(2)The temperature distribution and intensity of heat island in Beijing was studied.Urban and rural temperature in different seasons and intensity of heat island were analyzed.intensity and spatial distribution of heat island intensity changes in one day in Beijing were analyzed.Hierarchies were made among heat island areas in Beijing in accordance with the relevant rules.(3)The correlation analysis and regression analysis between PM2.5 and PM10 and major air pollutants were made.The correlation between concentration of PM2.5 and PM10 concentration and the intensity of heat island were analyzed,spatial pattern of which was analyzed...
