以青岛市为研究对象，基于青岛市1992~2013年夜间灯光数据和社会经济数据以及地理空间数据，分析灯光指数和各种社会因素指标的相关度，得出青岛市灯光指数与相关社会因素指标的拟合度较高，进而又通过城镇用地扩展的监测指标表征20年来青岛市的城镇扩展变化情况及空间分布变化情况。除此外，通过地理回归分析反演，运用人口、经济的因素表征灯光指数的变化验证青岛市城镇用地扩展变化以及空间分布变化。结果表明：青岛市在20年间城镇化水平持续提高，且在1992~2010年间城市化水平逐步加快，在2010年后处于减缓趋势，更加注重城市集约、节约型发展。青岛市发展的空间格局呈现中心圈层带动、组团式发展。也会存在空间发展不平衡的问题，前15年主要以东岸城区为中心发展，后5年更加注重整体发展。 Taking Qingdao as the research object, based on the data of Qingdao city from 1992 to 2013, the night lights and the social economic data and geographical spatial data, the analysis of all kinds of lighting index and social factors of correlation index, index of Qingdao city lights and related social factors index of fitting degree is higher, and through the monitoring index of the urban land expansion characterization of 20 years of Qingdao, the change of the urban expansion and the spatial distribution changes. In addition, by means of geographical regression analysis and inversion, demographic and economic factors were used to represent the change of light index to verify the change of urban land expansion and spatial distribution in Qingdao. The results showed that the urbanization level of Qingdao continued to improve in the past 20 years, and the urbanization level gradually accelerated from 1992 to 2010. The spatial pattern of Qingdao’s development presents the development driven by central circle and group. There will also be the problem of unbalanced spatial development. In the first 15 years, the development mainly centered on the east bank urban area, and in the last five years, more attention will be paid to the overall development.
