The Impact of Urbanization Development on the Meteorological and Environmental Elements in the Central Cities of Liaoning Province

Abstract

Based on the meteorological and environmental data on Shenyang, Anshan, Fushun and Benxi and the data on urbanization indexes in central cities of Liaoning from 1992 to 2012, this paper analyzes the law of annual changes of urbanization indexes and meteorological and environmental factors in central cities of Liaoning, and studies the influence of urbanization development factors on meteorological environment factors through correlation analysis, grey correlation analysis and the GM (1, n) model. Then the important influence factors are selected. The results show that the main urbanization factors affecting the wind speed, temperature, humidity and other meteorological factors in the central cities of Liaoning Province are the completed area of houses, population density, smoke and exhaust emissions, road length and so on. The urbanization factors that affect PM10, SO2, NO2 and other environmental factors mainly include the emission of smoke and gas, the total amount of water supply in the city, the completed area of houses and population density. The main influence factors of urbanization are different among in central cities of Liaoning. The fitting results of the GM (1, n) model show that there has a close relationship between urban development factors and meteorological and environmental factors. In addition, the GM (1, n) model has a high precision, which also shows the superiority of the GM (1, n) model in the application of urban multi factor correlation system.
