江西省县域农村居民纯收入空间差异研究

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

将ESDA空间相关分析理论和GIS技术相结合,揭示了1980-2009年江西省农村居民收入空间格局变化及差异。结果表明:江西省农村居民收入持续增长,绝对差异增大,相对差异明显缩小,空间结构呈纺锤型(中间集中型),集中于中上收入区、中下收入区和低收入区3种类型,空间格局变化明显;县域之间农村居民收入具有明显的正相关性,呈现空间上的集中分布,高收入区集中于浙赣铁路及京九铁路北段沿线,低收入区集中在赣南地区;1980年、1990年、2000年和2009年位于HH和LL象限的县域分别占总单元数的53.85%、69.23%、65.93%和71.43%,局部集聚格局显著,集聚能力不断增强。

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.
