河南省贫困人口空间分布及其地域特征研究

Research on the Spatial Distribution and Local Features of Poverty-Stricken Population in Henan

  • 摘要: 在GIS的支持下,构建河南省贫困人口空间数据库,对河南省贫困地区的分布特征、贫困人口空间分布的集散程度、贫困区域划分进行空间可视化表达.结果表明:(1)河南省贫困地区在空间分布上呈现出南多北少,西南、东南多而中部少的特点;(2)河南省贫困人口在周口市、南阳市分布最为集中,新乡市分布最为分散;(3)贫困人口的空间分布表现出相似值之间的空间集聚,并且在总体上趋向集中;(4)豫中、豫西、豫北、豫南、豫东五大地理区域的贫困程度存在显著差异,其中豫南和豫东地区贫困程度最为深刻;(5)根据各地市的贫困程度状况,可以利用Jenks自然断裂法将河南省划分成4个贫困类型区:基本脱贫区、低度贫困区、中度贫困区、高度贫困区.

     

    Abstract: The poverty-stricken population spatial database in Henan was built with the help of GIS. Furthermore,the distribution characteristics of poverty-stricken areas, the degree of poverty-stricken population agglomeration and diffusion, the division of poverty-stricken areas were visualized to better understand the law of poverty-stricken population distribution. The main conclusions could be drawn as follows:(1) most of Henan poverty-stricken counties distributed in South, Southwest and Southeast, minority of them distributed in north and central area;(2) the poverty-stricken population in Henan was the densest in Zhoukou and Nanyang, and that was the most dispersed in Xinxiang;(3) the spatial distribution of poverty-stricken population showed the agglomeration of similar values. The poverty-stricken population tended to centralize on the whole;(4) there were significant differences of poverty-stricken level in the five geographical regions of central Henan, western Henan, north Henan, south Henan and east Henan, and that was the most serious in south Henan and east Henan;(5) Henan was classified into 4 areas according to the poverty occurrencerate. The four areas were poverty eradication area, mild poverty area, moderate poverty area and severe poverty area.
