基于县域单元的河南农民收入区域分异时空格局

依据河南1995—2009年县域农民人均纯收入统计数据,采用数理统计和地统计分析法对农民收入水平区域差异时空格局演变态势进行深入探讨。研究表明,1995—2009年间河南县域农民人均纯收入水平绝对差异持续增大,而相对差异呈阶段性波动增大态势;县域农民收入水平表现出较强的空间集聚态势,整体上呈以豫中和豫西北县市为中心,以豫北、豫东、豫东南和豫西南地区县市为外缘的核心-边缘型空间格局,西北和东南部县市间差距在拉大,两极分化趋势增强。由此认为,加快提高豫东和豫东南农业县域的农民收入水平是推进全省区域协调发展的关键。

Spatial-temporal Pattern of Rural Resident' s Per Capita Net Income Based on County Scale in Henan Province

In the paper,based on county-level rural resident’s per capita net income statistical data from 1995 to 2009,the spatial-temporal pattern and evolvement trend of rural resident’s income disparity in Henan Province is deeply probed by mathematical statistical method and spatial statistical method.Results from mathematical statistical analysis show that the absolute disparity has been continuously enlarged since 1995,while relative disparity has been enlarged discontinuously from 1995 to 2009.Results from spatial statistical analysis show that spatial cluster of counties with similar net income level is always significant,the core zone of higher rural income stably located mainly in center and northwest Henan,while the marginal zones are composed of counties in north Henan,east Henan,southeast Henan and southwest Henan,and the core-marginal spatial pattern has been formed;the disparity between northwest and southeast counties has been enlarged and has been more and more polarized.And at last,the paper pointed out that it is significant to promote rural resident’s net income level in these very agricultural counties in east Henan and southeast Henan which will play a key role in coordinating regional rural resident’s income condition in Henan Province.
