The population distribution reflects the mode of the urban internal population and social spatial structure. Because the population data is very easy to obtain and can be compared in temporal and spatial series. A lot of researchers use population data to reflect the urban internal spatial structure. GIS technologies have been used in spatial structure research in the social sciences frequently recently. In this paper, Shenzhen city is taken as an example in this paper to show how to research urban internal population spatial structure based on GIS. The data of Fifth (in 2000) and Fourth (in 1990) censuses of Shenzhen is used in our research in two aspects. Between 1990 and 2000 every street's population density changed a lot, but the highest value street did not changed. The population center of gravity moved to north west about 4km from year 1990 to 2000. Several population density models were simulated for the population distribution. The method of curve estimation is used in finding the population density mode. The optimal population density mode was the Inverse distribution functions, which means that the further from the center and the spars the city would be. And the exponential model (Clark model) is not the best. The results of spatial auto correlation means that the population in the suburban was growing fast but centripetence in the city center still exists.
Key words： GIS; population spatial structures; Shenzhen city; urban internal space
