Abstract
This paper studies the urban spatial expansion of Xi'an City, the capital of Shaanxi Province of China, focusing on the temporal and spatial characteristics of the urban expansion during 1930-2002. Choosing Xian's built-up area as the study object and taking the geographic information system as the technical support, the paper establishes a series of Geoinformation Tupu to reflect the city expansion based on the Geo-information Tupu methods and multi-time remote sensing images, historical graphic document and data. It is proved that the spatial expansion had been expanding all the 70 years of 1930-2002 with different scales, paces, and directions. The build-up areas in Xi'an City had been growing outwards from inside circle basing on the ancient city with two expansion peaks and one nadir. By temporal analysis, it is founded that, firstly, the city expanded from east to west, then from north to south and finally from the center to outsides.
