With Yiwu topography map of 1:50000 in 1970 and remote sensing images (Landsat TM) in 1986, 1991, 1997 and 2002 as basis this paper makes analysis on temporal and spatial sequence according to the dynamics of urban pattern by GIS approach. Through both qualitative and quantitative analysis it comes to a conclusion that the urban pattern of Yiwu develops with accelerated speed and the spatial ex- tension tends to be axe-oriented, and the city has evolved from a strip-shaped pattern to an elliptical pattern.
