基于GIS的宁夏人口经济压力空间分布研究

空间分析是深入探索空间特征的重要技术,因此作者利用空间分析中的主成分分析方法和空间自相关分析对宁夏人口经济压力分类及其分布关系进行了深入探索,结果表明,宁夏人口经济压力从北部向南部逐渐增大,在空间分布关系上人口经济压力呈现明显的组团模式,北部区域以银川为核心呈低—低关联模式,南部区域以原州区为核心呈高—高关联模式。

Study on Spatial Distribution Pattern of Population Pressure in Ningxia based on GIS

The population pressure indexes of Ningxia were proposed and evaluated by employing the principal component analysis.The region was classified into different categories according to the population pressure indexes.Then based on this adopting spatial autocorrelation analyzing method used in spatial data mining,the author analyzed the spatial distribution pattern of population pressure.The study indicated that the population pressure in Ningxia decreased from south to north.The spatial distribution of population pressured demonstrated a spatial clustering pattern.There was low-low spatial correlation in the area of Yinchuan,Shi Zuishan and the surrounding areas,and a high-high spatial correlation in the area of Xiji,Yuanzhou and the surrounding areas.This kind of spatial distribution pattern should be paid much attention by the decision-making department of government.
