Abstract

Based on the Landsat remote sensing images of the fourth phase of Xi'an, the land use data of ENVI interpretation and classification are used to extract the boundaries of Xi'an's built-up areas, and the urban spatial analysis method based on GIS is used to comprehensively analyze the evolution characteristics of urban space in Xi'an in the past 30 years. The research results show that the built-up area in Xi'an has been expanding rapidly since 2000, mainly in the form of extension, the shape of the built-up area tends to expand in all directions, and the overall compactness is low, and the efficiency of urban land use is significantly reduced. The overall development presents spread trend.
