摘　　要：城市扩张的速度和方向已成为社会关注的焦点,利用夜光遥感进行城市扩张驱动力成因分析是近年来的研究热点。本文采用DMSP卫星所获取的年平均中国区域夜光影像数据,首先对1992—2012年共21年的时序夜光影像进行相对辐射定标;其次通过经验阈值法进行城市建成区面积提取,并通过Landsat影像进行精度验证;最后引入计量经济模型,以地级市主政官员政治周期为解释变量,对全国1992—2012年地级市扩张的政策驱动力因素进行了归因分析。通过本文的分析可知,地级市主政官员政治周期的更替对城市扩张方向存在显著影响。The speed and direction of urban expansion has become the focus of social concern, and it is a research hotspot in recent years that using night-light remote sensing for urban expansion driving force analysis of the causes. The average annual Chinese regional night-light image data is adopted that obtained by DMSP satellites. First of all, relative radiation correction is performed for 1992-2012, a total of 21 years of time-dependent night-light images. Secondly urban built area is extracted by empirical threshold method, and accuracy is verified through the Landsat images. Finally, the econometric model is introduced, the political cycle of the administrative officials of the prefecture-level city is the explanatory variable. It is analyzed the policy driving factors of the expansion of the prefecture-level cities from 1992 to 2012, Through the analysis of this article, we can see that the change of the political cycle of the administrative officials has a significant impact on the direction of urban expansion.
