Confirming the existence of spatial differences among different parts of urban areas, based on the 1:1 million digital geomorphic database and DMSP/OLS nighttime light data from 1992 to 2012, we explored the spatial characteristics of urban development in Beijing-Tianjin-Hebei region for recent 21 years, including the change of urban barycenter migration, the development difference of internal urban area and the relative development rate. Besides, we compared the development difference of urban areas among different macro-scale geomorphologies. The results show that: the barycenter of Beijing-Tianjin-Hebei region has moved south-west, north-east and south-west in sequence, and different cities have different barycenter migration routes and directions; the development level of Beijing-Tianjin-Hebei region has been steadily increasing, while the disparities between cities in this region have been reduced; for cities with different types of geomorphologies, the disparities between their own municipal districts have different changing patterns over time. For plain cities, the disparity basically keeps stable; for mountainous-plain or plain-mountainous cities, an implicit downtrend is indicated; and for mountainous cities, the disparity between their municipal districts declines gradually. The migration of mountainous cities’ urban barycenter is more obvious than cities dominated by other geomorphologic types, but these cities have an overall low development level. At last, we discussed the advantages of using DMSP/OLS nighttime light data, with the premise that heterogeneity exists in each city. We also pointed out that with regard to a long time series, there is evident relevance between urban development and urban geomorphology. A deep investigation into the relevance between the spatial characteristics of urban development and urban geomorphology is significant to understand the nationwide changes of urban development.
