Abstract: Abstract: Population spatial distribution is an essential factor of the urban spatial structure and
whether the distribution is optimal is one important feature of the healthy development of urbanization.
For many years，Beijing has not only focused on controlling population size，but also paid attention to
optimizing the population spatial distribution. Based on the ArcGIS spatial analysis tools and the 3d，
4th，5th and 6th census data，simulation results showed that from 1982 to 2010，the population in Bei-
jing central area tended to be dispersed and reasonably distributed，while the urban function develop-
ment zone tended to be more concentrated and unbalancedly placed. The later tendency will result in
serious traffic congestion，strain the education and health care resources and decrease the environment
quality. If efficient measures were not taken，the harmonious development and world city building
process of Beijing would be hampered. Optimizing the population spatial distribution of Beijing requires
comprehensive measures.
