中文摘要：

以河南省108个县（市）为研究单元,利用河南省相关统计数据,选取度量县域人口经济密度的9个指标,运用SPSS 17.0软件,对其进行主成分分析和系统聚类分析,并运用ARCGIS 10.2软件将河南省县域人口经济密度可视化表达,对河南省县域人口经济密度的地域空间分布进行研究,并提出相应的对策.结果表明：（1）人均非农业经济密度、人均信息化经济密度和人均农业经济密度是影响河南省县域人口经济密度的三大因子;（2）按照人口经济密度的差异对其聚类分析,可知河南省县域人口经济密度可划分为4种类型,分别为高水平区、较高水平区、中等水平区和低水平区;（3）通过对其可视化表达可以看出河南省人口经济密度总体上处于中等以下水平,占据河南省面积的2/3,且不同区域单元水平差距较大.

英文摘要：

Selecting 108counties（cities）of Henan Province as the study unit and using the relevant statistical data of Henan Province,9indicators were adopted to measure the county population economic density.The principal component analysis and the systematic cluster analysis were performed by using SPSS 17.0software,and the county population economic density in Henan Province was expressed visually by using ARCGIS 10.2software.The regional spatial distribution of the county population economic density in Henan Province was investigated,and the corresponding countermeasures were also put forward.Results show that：（1）the non-agricultural economic density per capita,information economic density per capita and agricultural economic density per capita are three major factors that affect the county population economic density in Henan Province;（2）according to the cluster analysis on difference of the population economic density,the county population economic density in Henan Province can be divided into four types：high level,higher level,middle level and low level;（3）through the visualization expression,one can see that the population economic density in Henan Province is overall below the middle level,covering two-thirds of the areas in Henan Province,and there is a significant difference in different regional units.
