Nantong is chosen as the object of study in this paper. According to the meteorological observational data for the period from 1951 to 2010 in Nantong, the changes of climate variables on the time series for nearly 60 years are analyzed through estimation of linear tendency and sliding average. It is found that: in the past 60 years, the average temperature is rising at the rate of 0.297°C / 10a, where the warming trend in spring is the most significant, and that in summer is the least. The trends of the min-mean and max-mean temperature are on the rise. The rapidly increasing changes of the extreme minimum and maximum temperature are observed. Over the past 60 years, the tendency of precipitation is generally on the rise with the small rate. The increasing trend of precipitation in summer is the most pronounced, followed by winter. Precipitation in spring and autumn is slightly decreasing. The contribution of the increase in precipitation mainly derives from the addition in summer and winter.

This paper chose urbanization and climate change of Nanjing city as the research object, by using trend analysis, correlation analysis, multivariate linear regression analysis and other methods, using the climate data and social statistical data of 1951~2011 observation stations in Nanjing City, analyzing the trend of city climate change and the correlation between different parameters and main climate factors. Results show that, the warming trend in Nanjing is very weak, the mainly temperature change is a rising temperature in winter, while it was not obvious in summer, reduce the heat wave phenomenon, the average year temperature has increased slightly; over the years precipitation showed increasing trend, the sunlight hours was decreasing, in addition to the city dark island effect. Through the analysis of the relationships between urbanization and climatic factors found that close relations between urbanization and annual mean temperature, and its impact is significant, and the impact of extreme minimum temperature is not very obvious, but the but the influence of extreme maximum temperature is obvious. In addition, in the analysis of Nanjing found that years of reform and opening up has become theories of demarcation point climate change trends and impacts of urbanization on climate change, before and after the cut-off point on climate change and the effects of urbanization on climate change have has the remarkable differences, the reason and mechanism still need further analysis and discussion.

According to the meteorological observation data in Nantong, 1951-2010 and the economic and social statistics, this paper studies the correlation between climate change and urbanization, discusses the impact mechanisms of different indicators of urbanization on different climatic factors, puts forward the responsiveness and adaption countermeasures to the climate change that will provide decision-making basis for the realization of the sustainable urban development in the context of climate change in Nantong and draws up the urban planning to respond and adapt to the global climate change for the government and provides a reference for the development strategies on the basis of the analysis of the climate change and urbanization development of the city’s nearly 60 years.
