Abstract:Dongsheng district of Erdos is selected for studying the influence of urban development on atmospheric environment. Based on the meteorological observational data from 1961 to 2006, sounding data at 08:00 and 20:00 o’clocks from 2002 to 2006, main pollutants concentration and its sources concentration from 2001 to 2006, the social economic data from 1961 to 2006, satellite image in 2002 and urban planning data in 2020 etc., the effects of urbanization on the local atmospheric environment in Erdos were analyzed by using a region boundary layer model (RBLM1.0). The results indicate that the air temperature would be lower in 2020 than in 2002 and the temperature difference between urban center and its surrounding area would be reduced, which is benefit for improving the urban atmospheric environment. After the urban area enlargement, convergence region of airflow reduces and divergence ability strengths in winter (serious pollution season), which is benefit to lighten the urban pollution and improve the atmospheric environment. The layout of underlying surface is changed because of urban enlargement, so airflow filed changes greatly in Dongsheng district. However, the urban pollution would be lightened in terms of dispersal ability of pollutants if the layout is carried out.
Keywords:Atmospheric environment  Simulation  Impact assessment  Erdos
