Analysis on Spatial Distribution of Population in Jiangxi Province Based on ESDA

Population distribution refers to the form of space existing and the distributing condition in a certain time,which includes different area distribution of the total population and some specific population distribution.By means of spatial autocorrelation analysis theory and combined with GIS technology,this article discusses the changing rules and characters of the population's spatial distribution in the counties of Jiangxi province between1978 and 2010. The results show: the total of population keeps increasing in the research period,yet the increasing speed slows up; the dispersion degree,the relative gap and the absolute difference of the population density enlarge; the population distribution of the whole province has the characteristics of higher in the north and lower in the south. Besides,the number of the counties located in H-H and L-L quadrant in 1978,1990,2000 and 2010accounts for 80. 21%,78. 02%,69. 23% and 68. 13% respectively,which shows the gathering of the population's spatial distribution has a tendency to decline since the last 30 years in Jiangxi province.
