With the rapid development of urbanization, the urbanization in Central Asia become con- cerned about the new research directions in recent years. In this paper, using remote sensing images in 1989,2000,2010 year of the capital of Uzbekistan, Central Asia＇s second largest city, Tashkent, got the in- formation of urbanization and also analyzed spatio--temporal changes using the average annual rate of ex- pansion.fractal and urbanization intensity index. The results show that. Over the past 20 years, Tashkent city land use types have significant changes; especially the changes of urban land are more obvious. Con- struction sites constantly expanding, during the first period 1989--2000 the expanding area of average an- nual expansion and urbanization intensity index are 4.55 kmz and 1.99 % respectively; during the second period 2000--2010 the expanding area of average annual expansion and urbanization intensity index are 7. 38 km2 and 2.55 %. The increasing of urban area mainly converted from the surrounding grassland and un- used land; Extension strength （2.86%） in 2000--2010 is higher than the period of 1989--2000 ;The frac- tal index was increasing,implying that the urban spatial configuration in Tashkent became more and more complex.
