Abstract:

The aim of this study is to reveal the spatial and temporal variations of the main atmospheric pollutants in Daqing City by mathematical analysis of the monitoring data according to the atmospheric environmental monitoring data for nearly 15 years of Daqing City. The comprehensive pollution index method, the pollutant load factor method and the rank correlation coefficient method were used for the evaluation of atmospheric environmental quality. The results showed that the air quality of Daqing City was good as a whole in 15 years and it improved better step by step. Dusts and PM10 were the major air pollutants and the weight of NO2 was increasing year by year. In addition, the air pollution type was developing from “coal smoke” to “oil smoke”. Spearman rank correlation coefficient method was used to analyze the trend and significance of the main air pollutants in Daqing City. The results showed that PM10, dusts and SO2 presented downward trend and NO2 Presented upward trend, but the trends were not significant and fluctuated on the same level. The task of energy-saving and emission-reduction will be still arduous for Daqing City.
