Abstract:

This paper designs a model to calculate an index of population distribution for each county and province. The index is related to the density of population, natural condition, the level of economic development and the density of traffic lines. A population barycenter of a province is defined according to which county index is closest to the provincical one. Then a 3D space of population distribution is established using the index (z) and the coordinates (x, y) of the barycenter. The distance in 3D space is calculated between any two provinces. According to the principle of minimum distance, China is classified into eight regions of population distribution.

Key words: population, spatial distribution, regionalization
