20世纪90年代以来我国进入城市化快速发展阶段,城市规模迅速扩张,这在一定程度上对于环境系统产生了影响,如产生了城市热岛效应。文章利用灰色系统理论,对我国25个省会城市和4个直辖市1990～2005年的城市化综合发展水平数据和城市气温数据进行了灰色关联度的计算和分析,定量揭示了城市化水平的差异对于城市气温变化的影响,同时也定量分析了各种城市化因子对于城市气温变化的影响。
Since the 1990s, our country has entered the stage of rapid urbanization and the rapid expansion of urban scale, which to some extent has had an impact on the environmental system, such as the urban heat island effect. By using the gray system theory, this paper calculates and analyzes the urbanization level data and urban air temperature data of 25 provincial capitals and 4 municipalities from 1990 to 2005 in our country, and quantitatively reveals the difference of urbanization level to The impact of urban temperature changes, but also quantitative analysis of the impact of various urbanization factors on urban temperature changes.
