Analysis on Spatial Difference of the Rural Resident's Net-income in Jiangxi Province

Based on the exploratory spatial data analysis(ESDA) and GIS technology,this paper analyzed the spatial difference of rural resident's net-income in Jiangxi province from 1980 to 2009.Reults showed that rural resident's net-income has been steadily increasing,but the absolute difference has been expanding while relative difference has been reduced;the general structure of rural resident's net-income at county level was spindle-type,upper middle income district,lower middle income district and low income district were the main 3 types;county rural resident's net-income showed a positive spatial autocorrelation and significant global spatial clustering pattern.The high income district mainly distributed along the Zhe-gan Railway and the north of Jing-jiu Railway,low income district was in the south of Jiangxi province.Counties fell into the quadrant of the HH and LL accounting for 53.85%,69.23%,65.93% and 71.43% of the total size in 1980,1990,2000 and 2009,respectively.The significant local spatial clustering pattern was significant,the clustering power is enhancing constantly.
