摘要
基于地理信息系统技术,运用主成分分析和空间自相关分析方法对西北少数民族地区经济发展的空间分异进行了研究。首先对西北少数民族各地区的经济总体发展水平进行了综合评价与分析,并划分为四类区域;其次,揭示了各地区经济总体发展水平的空间分布特征。研究区在整体空间分布上呈现出显著的空间集聚分布模式。在局部空间分布上,经济发展水平较高的聚集区太少、较低的聚集区太多,且存在极化效应较强的"热点"现象。
Based on GIS technique, we studied the spatial differentiations ity nationality areas of the northwest China by using the analysis methods autocorrelation. Firstly, the research areas were divided into four parts and analysis of economic development level. Secondly, the characters of of economic development in the minor- of the principal component and spatial through the comprehensive assessment spatial distribution of economic develop- ment level were shown. The whole spatial distribution shows a remarkable spatial clustering distribution pattern. The local spatial distribution shows that the spatial clustering regions of high economic development level are few, the spatial clustering regions of low economic development level are excessive and the polarization effect of ＂hot point ＂phenomenon is strong.
