摘要
以县级区域为研究单元,采用空间自相关分析方法,利用1999-2007年时间序列数据,对河南省农民人均纯收入的时空演变过程进行分析,结果表明:1)收入相似的县域空间集聚始终非常显著,总体空间相关程度基本呈增加趋势;2)农村经济高收入核心区分布较稳定,以焦作、郑州、许昌为中心集中分布,在全省农村经济发展势能最高;3)农村经济塌陷核心区在空间上从豫西中部迁移到了豫东中部;4)呈现显著空间异质性的县域主要位于高收入核心区和低收入核心区的边缘,一直未形成明显的空间集聚;5)高收入核心区和低收入核心区始终呈现明显的空间分异,宏观空间分异表现为北高南低、中部高东西部低的总体空间分布特征。
With the aim of probing the laws of spatio temporal evolution for per capita net income of rural residents in Henan Province,and based on all the county-level statistical data from 1999 to 2007, spatial autocorrelation analysis method and GIS technology which can well reflect the regional economy disparities are used in this paper. Global and local spatio-temporal variation indicates..1）spatial cluster of counties with similar value is always significant, while the global spatial autocorrelation level increases slightly by and large;2）core zone of higher rural income is distributing stably which centres on Jiaozuo, Zhengzhou and Xuchang;3）core zones of lower rural income have transferred from the middle of west Henan to the middle of east Henan since 2003 ;4）counties which present spatial heterogeneity scatter around the core zones of higher and lower rural income, and those have never formed conspicuous spatial cluster; 5）high-high and low-low significant areas represent spatial differential obviously all the time,macroscopical spatial differentiation characteristics exhibit that it is higher in north and middle Henan while lower in south,east and west Henan.
