Abstract: In order to provide scientific decision-making basis for the implementation of the rising strategy in
central region, the formulation of regional population policies and the promotion of population economy and
resource environment balance in Hubei Province, a method of dynamic simulation and evaluation of regional
population spatial distribution pattern based on the analysis of population density patterns at multiple geographical
scales of urban, urban agglomerations and provincial provinces is proposed. Geostatistical analysis method,
spatial autocorrelation analysis, segmented regression model and other methods are used in the research. Based
on this, the dynamic simulation of population structure in Hubei Province from 1990 to 2010 was carried out on
three geographical scales of Wuhan-Wuhan Metropolitan Area-Hubei Province. The results show that Wuhan is
still in the early stages of urbanization, and the population of which continued to gather towards the center, its
population structure is divided into two different structural bands. Spatial distribution of population has showed
significant agglomeration characteristics at all three geographical scales. Population density gradient tends to be
smooth with the expansion of geographical scale.

Key words: multiple geographical scales, spatial-temporal analysis, urban structure, urbanization,  population density gradient
