利用宁夏各县区2008—2013年的人口、GDP数据,借助Arcgis10.0软件,对宁夏人口与经济分布的地域差异及格局演变进行研究,结果表明:(1)2008—2013年宁夏人口不均衡程度加深,经济不均衡程度减弱,但经济不均衡程度仍高于人口不均衡程度。(2)2008—2013年全区人口地理集中度格局总体上变化不大,宁夏北部地区的银川市和石嘴山市受首府经济和矿区开发影响,集中指数较高。(3)经济和人口的地理集聚存在一定的相关性。(4)2008—2013年,宁夏“人口和经济基本一致型”的地区有所增加,但仍然以“人口集聚高于经济集聚型”为主。并在文章结尾提出了相关对策建议,以期对同类区域的发展提供参考。
Based on the population and GDP data from 2008 to 2013 in the counties of Ningxia, the regional differences and pattern evolution of the population and economic distribution in Ningxia were studied by means of Arcgisl0.0 software. The results show that: (1) The unbalanced indexes of population and economy Ningxia distribution of 2008-2013 are positive. There is a significant positive correlation between regional population and economy. Regional population and economic structure have a trend of convergence. (2) The overall pattern of the geographical concentration of population of 2008-2013 doesn't change much. The areas with high concentration index are mainly distributed in the capital city of Yinchuan and in the city of Shizuishan, the northern part of the mineral resources. (3) The polarization effect of economic geography is significantly greater than the agglomeration effect of the population and there is some correlation between these two. (4) In 2008-2013, the number of area of which population and economy are basically consistent in Ningxia increases. But the population is still higher than the economic agglomeration.
