Abstract: The current urban surveying and mapping results are abundant and the time series is good.The value and role of historical surveying and mapping results should be fully explored.This article uses spatial statistical analysis, standard deviation ellipse, and kernel density analysis methods to study and explore the spatio-temporal evolution of surveying and mapping results on urban construction land, deeply analyze the development status of urban construction, and quantitatively evaluate the classification of urban construction land and the spatio-temporal evolution analysis of urban spatial expansion, explore the characteristics and trends of urban changes and development, and provide scientific theoretical and technical support for urban development, utilization and protection, national spatial planning, use control, and implementation supervision.

Key words: construction land, spatio-temporal evolution, standard deviation ellipse, kernel density analysis
