摘　　要：以淮海经济区为研究区域,运用主成分分析法、探索性空间数据分析和地理探测器法,分析了淮海经济区社会发展的区域分异,并揭示了贫困县分布的区域特征,探讨了影响贫困的主要因素.结果表明:淮海经济区贫困县尤其是国家级贫困县主要分布于皖北和豫东地区,呈现显著的东西差异,并由皖北—豫东向苏北—鲁南逐渐递减;从空间格局来看,淮海经济区县域贫困具有很强的空间依赖性与集聚特征,经济社会发展水平低值集聚区与低值分散区主要分布于豫东和皖北地区,高值集聚区与高值分散区则主要分布于苏北地区与鲁南部分地区;淮海经济区县域贫困是多种因素共同作用的结果.Taking Huaihai Economic Zone as the research area,using the principal component analysis method,exploratory spatial data analysis method and geographical exploration analysis method,the regional differentiation of social development in Huaihai Economic Zone,the characteristics of the distribution of poverty counties and the main influencing factors were analyzed.The results showed that the poverty-stricken counties in Huaihai Economic Zone were mainly distributed in the northern Anhui and eastern Henan,showing significant East-West differences.From the perspective of spatial pattern,the poverty counties of Huaihai Economic Zone had strong spatial dependence and agglomeration characteristics.The low level of economic and social development accumlation and dispersion area were mainly distributed in eastern Henan and northern Anhui,while the opposite area were mainly distributed in northern Jiangsu and southern Shandong.County poverty in Huaihai Economic Zone was caused by many factors.
