城市化进程对南京气温变化的影响

Using the temperature data of Nanjing and Gaochun stations and urbanization development information of Nanjing from 1960 to 2010, combined with statistical analysis, principal component analysis, regression model to analyze the varsiations of air temperature, and researched the impact of urbanization development on Nanjing air temperature. The results show that the annual mean temperature, minimum temperature and maximum temperature at the area near Nanjing is rising remarkably and conformably in the 50 years, warming rate in urban is greater than in the suburb, but reduction rate of temperature daily range in urban is greater than in suburb; The sharp rise happened in the late 1990s, when rapid urbanization emerged in Nanjing. The dominant factors that influenced temperature change during urbanization included population, land using type, energy consumption and reasonable level of urban development planning, its common interpretation of the rate of up to 83%.
