中国主要大气污染物的时空分布特征研究
The Temporal and Spatial Distribution Characteristics of Main Air Pollutants in China
摘要
Abstract
In order to analyze the temporal and spatial distribution characteristics of NO2, PM10, PM2.5and SO2 in China, 190 cities' data of the fourair pollutants from March 2014 to February 2015 were evaluated by statistical method and GIS. Results showed that the main sources of pollutants in China derived mainly from heating emissions, motor vehicle emissions, industrial emissions and sand storm. The four pollutants performed an obvious regional distribution, which indicated thatthe concentration in North China is higher than that in South. The region with large population and heavy industries, such as southern Hebei and eastern Shandong, were severely polluted. And the region with less population and industries, such as Midwest and Southeast China, were slightly polluted. The concentration of PM10 was highly affected by season and climate, for example, PM10 was significantly influenced by coal in heating period, but by sandstorm weather in non-heating period. The concentration of PM2.5, SO2and NO2 all increased in heating period, while SO2 was the most sensitive pollutant. The pollution caused by NO2 in developed areas is more serious, which attributed to the industrial and vehicle emissions. Above all, the pollutants' concentration distribution was different in heating and non-heating period, and coal combustion had a significant negative impact on air pollution in heating period.关键词
