Abstract This paper selected three indices,Normalised Difference Built-up Index (NDBI),Modified Normalised Difference Water Index (MNDWI) and Normalized Difference Vegetation Index (NDVI) to represent three major urban land use/cover types:building plot,water and vegetation respectively by detailed analysing the two remote sensing TM images of Xi’an City in 2000 and 2007. Then the study classified the imge through the neural network classification module ,calculated types of land use in Xi'an Dynamic transfer matrix, constructed the land use change index and dynamic index and analyzed spatio-temporal changes of land use in Xi'an by using Erdas I-magine 9.0,ENVI, ArcGIS 9.2 and Matlab software platform. The result came to that the driving forces of change of land use in Xi'an were population growth, economic growth,urbanization development and policy change.
