摘要
基于ESDA相关分析以及百分位数和变异系数,在ArcViewGIS和GeoDA空间统计分析软件的支持下,对湖南省县域人均GDP的空间格局特征,空间关联特征和相对差异演变过程进行实证分析,为湖南省制定合理的区域经济发展战略,进一步实现区域全面协调可持续发展提供理论指导和参考.研究结果表明:a.在空间格局上,湖南省县域人均GDP东高西低,呈现两级核心-边缘模式,倒U字型县域经济差异特征显著;b.通过空间关联分析,在总体空间格局上各县域人均GDP的分布存在正的全局空间自相关,局部空间集聚结果包括HH、HL、LH和LL四种类型;c.县域人均GDP相对差异演变自2000年至2008年整体上呈扩大趋势,2000-2004年期间相对差异趋于稳定,2005年差异程度急剧上升,2006年至2008年呈平缓上升趋势.
Based on the related analysis of Exploratory Spatial Data Analysis（ESDA） as well as Percentile rank and coefficient of variation,it is investigated the current spatial economic pattern,spatial auto-correlation and evolution process of relative difference in Hunan Province at county level by analyzing the GDP per capita data from 2000 to 2008,With the support of Arc View GIS and GeoDA software.It aims at providing scientific evidence and reference for the rational developmental patterns of Hunan,further to achieve comprehensive,coordinated and sustainable develop-ment.Empirical results are drawn as follows.a.Taking current spatial economic pattern into account,the GDP per capita in eastern area of Hunan Province at county level is obviously higher than that of in western area.,a typical pattern of two-level Core-edge is presented throughout the overall space together with an inverted-U pattern among regional economic relative differences.b.The GDP per capita at county level shows a strong trend of spatial auto-correlation.All counties can be divided into four types of LISA clustering,including HH,HL,LH,and LL.c.the general trend of the evolutionary processes of GDP per capita at county level in Hunan province can be identified as expanding.The degree of expanding from2006 to 2008 is higher than that of from 2000 to 2004,while keeps relatively stable during each mentioned period above,except for a leap in 2005.
