Taking Urumqi as a case, a simulation of urban population spatial distribution is proposed based on urban land use and
population statistical data using GIS, and population spatial distribution patterns are analyzed by the raster population
surface. As a result, generating raster population spatial distribution surface is more accurate and natural than the
traditional choropleth map of population density in Urumqi. Concerning the population spatial distribution of Urumqi,
the population density declines from south to north and the population distribution mainly presents "T-type", the
population distribution presents polycentric agglomeration and the population distribution of the districts shows different
features. The population density varies significantly with the increase of the distance from CBD. Finally, this paper finds
that the development history of districts, terrain and traffic road are main factors influencing Urumqi's population
distribution. This paper tries to provide more accurate data of population distribution for the plan and management of
urban land, traffic and public facilities in order to enrich the researches of urban population distribution.
