[Abstract]:With the acceleration of urbanization and industrialization in China, the influence of human factors on urban climate and air quality is becoming more and more obvious, and the problem of urban heat island effect and urban air pollution is becoming more and more prominent. Industrial production and combustion of mineral fuels release a great deal of heat, but also accompanied by a large number of atmospheric pollutant gas emissions, among which, PM2.5,PM10 pollution on the urban atmospheric environment has a great impact. These pollutants can affect the atmospheric transport process, change the vertical movement of urban atmosphere, thus affect the urban air temperature, and further affect the distribution of urban heat island. The effects of pollutants on urban heat island are different in different cities due to the different topography and landform as well as the location of pollution sources. The study of the distribution relationship between the two plays an important role in understanding the cause of the formation of urban pollution and heat island effect and the mechanism of pollutant transfer, and plays an auxiliary decision-making role in the urban layout, the location of factories and the control of air pollution. In this paper, the relationship between urban heat island effect and PM2.5,PM10 concentration distribution in Beijing is studied from the following aspects by using the data of environmental monitoring points and meteorological stations in Beijing and remote sensing data. The research contents are as follows: (1) the main air pollutants in Beijing are studied, the different pollutants in different types of monitoring sites are discussed month by month and quarterly, and the variation of pollutants in one day is analyzed. The spatial distribution of PM2.5,PM10 concentration was studied. According to the national air quality standard, the pollution grade of PM2.5,PM10 pollution area in Beijing was classified. (2) the distribution of air temperature and the intensity of heat island in Beijing were studied. The temperature and the intensity of the heat island in different seasons were analyzed, and the change of the intensity of the heat island in one day was analyzed. This paper analyzes the spatial distribution of heat island in Beijing, and classifies the heat island area in Beijing according to the relevant classification rules. (3) the correlation analysis and regression analysis between PM2.5,PM10 and main air pollutants are carried out. The correlation between PM2.5,PM10 concentration and heat island intensity data was analyzed in time and the spatial pattern of both was analyzed.
