太原市城市化发展对城市气温变化影响的定量化研究

采用位于同一纬度的太原气象站与远郊区农村气象站获取的1957年-2014年的气象数据,用皮尔卡森相关系数、一元线性回归、城市化影响分析等方法研究了在全球气候变暖背景下城市地区气温变化趋势以及城市化影响.结果表明:城市年平均气温升高趋势明显高于农村;城市年极端高温与农村极端高温升高趋势差异不明显;城市年极端低温升高趋势显著高于农村.就城市化影响而言,城市化对年平均气温、年极端低温趋势影响明显,但对年极端高温趋势影响微弱.

Quantitative Research on Influence of Urbanizationon Urban Environmental Temperature Change in Taiyuan

The study took meteorological data in cities on the same latitude with Taiyuan city(53772) and its countryside(53780) to analyze the implication of urbanization to the tendency of regional temperature and the asymmetrical changes of air temperature based on the Pierre Carson correlation coefficient, linear regression and non-symmetry analysis.The results show:the tendency of annual average temperature in urban area is significantly higher than that in rural area;extreme high temperature of urban and rural suburban area change in the same way.While comparing with the rural suburbs, the extreme low temperature average temperature increases significantly than city.In terms of influence of urbanization, the influence of tendency of urbanization on the annual average temperature and extreme low temperature are obvious, while on the extreme high temperature is weak.
