By using statistical yearbooks,census data,remote sensing images,we extracted all population data for the past 10 years at the Urumqi City's administrative region units,and we determined the changes in population distribution over the years in each unit of the study area. By excavating the relationship between population and time variables in the study area,we established a population forecasting model(GM(1,1)model)to predict population data in various districts of Urumqi in the next two years,and to make up for the data gaps that could not be updated in the next two years in the database.
