宁夏城乡关系空间分异研究

Study of spatial pattern of urban-rural relationship in Ningxia

为了对宁夏城乡关系进行定量评价及空间分异研究,该文基于2013年宁夏19个县区城乡发展数据,构建评价指标体系,采用关联度模型、协调度模型、统筹发展度模型和ESDA-GIS空间分析方法对宁夏城乡关系发展水平和空间格局进行研究。结果表明:宁夏城乡关联度、协调度和统筹发展度整体水平较低,城乡发展呈现"北高南低"的空间分布格局,空间分异明显,空间集聚特征显著,与经济社会发展呈明显的相关性;南部山区是城乡发展的"塌陷区",北部地区是宁夏城乡发展的"核心区";原州区空间极化效应显著,县域尺度的城乡关系空间格局研究较为合理地反映了宁夏的实际状况。

In order to make a quantitative evaluation of the relationship between urban and rural areas and do the spatial differentiation research in Ningxia, by using the models of correlation, coordination, and overall development, ESDA-GIS spatial framework, the development level and spatial difference of urban and rural in Ningxia were analyzed based on the statistical data of 19 counties in Ningxia Hui Auton- omy Region in 2013. The result showed that it had a low level of correlation, coordination, and overall development, presented a pattern of ＂high north and low south＂, and closely associated with their eco-- nomic and social development; the counties with high levels of development between urban and rural areas were located in northern Ningxia, some counties with low levels were located in southern area; Yuanzhouqu showed space polarization effect significantly, the relationship between urban and rural areas at county scale more reasonably reflected the actual situation in Ningxia.
