Abstract: The spatial distribution of urban population can reflect significantly urban functions and development status. Shenyang, as a typical old-industrial city in China, has changed obviously in population spatial distribution in the process of urban transformation, which is causing the change of urban spatial structure. Based on the subdistrict data from 1982, 1990 and 2000 Chinese national population censuses, this study simulate the evolution pattern of urban population spatial distribution in Shenyang city. Using statistical and spatial association approach, we find that the population distribution, on the whole, have shown an even and decentralized trend since 1980s, which characterize with China’s suburbanization. Furthermore, employing density models to investigate the pattern of population distribution, it is concluded that the negative exponential model fitted the distribution best, and population concentration in the inner suburban keep increasing gradually, meanwhile, the spatial structure of population distribution have presented polycentric characteristic in 1980s. The parameters of model show that population concentration in the urban core keep significantly all the time. The increase of population in the inner suburb influence on the population distribution pattern more and more importantly, but the concentration intensity of population cores in inner suburb is still small.
