基于GIS的陕西省人口空间分布模式

借助空间自相关分析方法分析了陕西省人口的空间分布模式和空间关联关系。结果表明,陕西省人口分布呈现显著的空间集聚现象,在整体上具有较强的正相关性。在西安市附近存在几个非常明显的"高-高"集聚;同时,延安市和安康市分别出现"低-低"集聚。陕西省人口重心从2002年的礼泉县移动至2009年的泾阳县,向东北移动约3.3 km。

Population Spatial Distribution Pattern of Shaanxi Province Based on GIS

The distribution pattern and spatial correlation of Shaanxi Province’ population was analyzed based on spatial auto-correlation in this paper.The results showed that there was the remarkable spatial clustering for population distribution of Shaanxi Province and the strongly positive correlation on the whole.In the vicinity of Xi'an City there were several obvious"high-high"clustering,and there were also some"lowlow"clustering in the research areas which were located separately at Yan’an City and Ankang City.The gravity of Shaanxi Province’ population moved to Jingyang County from Liquan County of Xianyang City from 2002 to 2009,and the distance of movement was approximately 3.3 km to northeast.
