Abstract: In order to solve the shortcomings of traditional research methods in the detection of urban spatial evolution, a new method was proposed to respond to China's land refinement transformation, and to improve the in-depth application of optical satellite and remote sensing technology in the social and economic fields. Based on the Beijing-Tianjin-Hebei urban agglomeration, urban evolution and industrial transfer models were used to analyze the spatial and temporal characteristics of its evolution from 1990 to 2020. The results show that, ① the overall evolution intensity presents an "up-down" trend, showing the hot spots of evolution around Beijing, Tianjin and Tangshan, and Shijiazhuang-Baoding cities. ②The comprehensive development of Beijing, Tianjin and Tangshan cities shows a downward trend, while that of Shijiazhuang, Handan and Xingtai cities shows an upward trend. ③The regional industrial chain shows a trend of agglomeration and diffusion in space. The middle and high technical industries gather in the larger cities, while the middle and low technical industries move to the surrounding cities. The research proves that optical satellite possesses great potential in urban development monitoring, which can provide a certain reference for the planning and decision-making of regional integrated development.
