Land use and land-cover change has received great attention from scientists all over the world for a long time. In particular, studying the spatial-temporal characteristics of urban construction land and orienting the urban function accordingly is significant for promoting urban sustainable and scientific development. This paper focused on the urban construction land of 13 cities in the Beijing-Tianjin-Hebei region during 1985-2015 and analyzed their spatial-temporal characteristics by both quantitative and qualitative methods. Then, the driving factors of differentiation on temporal evolution and spatial pattern of urban construction land were detected by multiple linear regression, path analysis and geographic detector method. Based on the dominant mechanism of driving factors, function orientation of urban development in the study region was proposed. The major results were showed as follows. First, there were obvious spatial differences of expansion, speed, direction and stability of urban construction land, and the 13 cities can be divided into stable and coordinated type, fluctuant and coordinated type, stable and uncoordinated type, fluctuant and uncoordinated type.Second, the main driving factors of the temporal evolution of urban construction land in this region included GDP index, population density, and financial income index, while the dominant factors of spatial evolution of urban construction land included distance to the city center, distance to the main river, and distance to the main highway. Finally, according to these results, the 13 cities were accurately and scientifically divided into the core economic leading cities, key economic development cities, and economic stable and conservation cities, which provide some references for the coordinated and integrated development of the Beijing-Tianjin-Hebei region.
