Wuhai City, Inner Mongolia Autonomous Region in western industrial city. Currently, the formation of the four leading industries of energy, chemicals, building materials, specialty metallurgy. Wuhai City air quality of the environment by industrial pollution and smoke pollution affect the formation of the spatial and temporal patterns of various pollutants. This article by Wuhai City calendar atmospheric environment monitoring data statistics, summarizes the characteristics of temporal and spatial variation analysis of the reasons of urban air pollution, combined with the actual situation of Wuhai City Pollution Control Measures for future Wuhai City environmental management and decision-making data and theoretical basis, the Wuhai City Atmospheric Environmental Protection theoretical value and practical significance. The main conclusions of this paper are as follows: 1, Wuhai City key sources of pollution analysis results show that the emission from the exhaust emissions of various industries, petroleum processing, coking and nuclear fuel processing industry, the production and supply of electricity and heat, non-metallic mineral products industry The amount of the top three. Sulfur dioxide, soot emissions by the top three: electricity and heat production and supply industry, oil processing, coking and nuclear fuel processing industry, non-metallic mineral products industry. 2, Wuhai variation of atmospheric pollutants: Wuhai urban air monitoring data for the 2004-2010 is based on the variation of urban atmospheric pollutants. The results show that: Since 2004, SO2 concentration, Wuhai City interannual trend downward trend, and relatively stable; 2010 annual average SO2 concentration values ??of the national environmental quality standards. Annual variations in NO2 concentrations, decreased concentration, but volatile, unstable evident Overall, the relatively light pollution over the years were not excessive, but the daily mean value exceeded the phenomenon exists, appeared in 2004; PM10 concentration interannual variation characteristics of view, more than the national secondary standard, after 2007, reaching three national environmental quality standard. 3, the Wuhai urban air pollution causes: (1) natural environmental factors: topography, atmospheric stability, wind direction, wind speed and precipitation weather situation. (2) socio-economic factors: the layout of the city, the industrial structure and industrial distribution situation, industrial and domestic fuel combustion, the combined effects of vehicle exhaust emissions, infrastructure construction and other factors. Wuhai City Air Pollution Situation, pollution prevention measures recommended.
