Abstract: The paper based on the data of national geographic monitoring, combined with the statistical data of urban economy and population in the same period, uses high-resolution satellite remote sensing image data to extract boundary elements of Beijing built-up area. It combines urban spatial expansion with relevant evaluation indexes to carry out the analysis and research on spatial pattern change. It reveals the spatial pattern and its changing rules of urban expansion in Beijing from 2000 to 2017 and analyzes the reasons for the change, The results can provide a decision basis for scientific planning and sustainable development of Beijing.

Key words: geographical conditions, urban space expansion, urban spatial pattern, urban spatial structure, spatial pattern change
