摘    要:基于ESDA与GIS技术,利用三峡库区重庆段各区县1998-2011年人均GDP数据,对该区域经济发展的空间格局及其时空演变进行了分析,结果表明:三峡库区重庆段经济空间分异明显且呈显著的空间正相关,在整体格局上呈现出一定的集聚态势;全局上看,三峡库区重庆段经济相对差异在缩小,从局部来看,空间集聚表现在重庆主城和渝东北库区,而库区中段的集聚态势表现不强烈;万州区在有关政策扶持下,经济发展加快,有望成为带动渝东北库区经济发展的增长极.

关 键 词:区域经济差异  时空演变  探索性空间数据分析  地理信息系统  三峡库区

Abstract:Based on the method of ESDA and GIS ,the economic space pattern and spatial-temporal evolu-tion of regional economic development in T hree Gorges Reservoir of Chongqing have been analyzed in this paper with the data of GDP per capita at county level from 1998 to 2011 .The results indicate that the county's economic development in T hree Gorges Reservoir of Chongqing has obvious spatial differences and significant spatial positive correlation .By means of global spatial autocorrelation analyses ,the economy relative disparities in T hree Gorges Reservoir of Chongqing have been decreased over time .By means of lo-cal spatial autocorrelation analyses ,the main urban area Chongqing and Three Gorges Reservoir in North-east of Chongqing have strong spatial agglomeration , but the middle of T hree Gorges Reservoir of Chongqing is not strong .Under the support of related policy ,economic development of Wanzhou District has speed up and it is expected to become a economic grow th pole to lead the economic development of northeast of Three Gorges Reservoir of Chongqing .
