以重庆区县为研究单元,选取综合指标,借助arcgis9.3、geoda10.0软件,运用空间自相关分析方法,对重庆区县经济发展水平空间差异进行研究.结果表明:2010年总体空间分异特征呈现出“一圈”高,“两翼”低的态势,“一圈”、“两翼”内部分别形成了圈层与单中心发展格局.2000-2010年重庆区县经济发展水平差异空间集聚显著,但总体的空间差异逐渐减小;Moran散点图显示位于一、三象限区县数量较多,表明呈现空间异质性区县数量不多,空间分布不均衡;期间部分县域集聚类型发生变化,但“高高”、“低低”县域分布的总体格局并未发生较大变化.
This paper takes Chongqing area as the research unit, selects comprehensive indexes, and uses arcgis9.3 and geoda10.0 software to study the spatial difference of economic development level in Chongqing by using the method of spatial autocorrelation analysis.The results show that the overall spatial differentiation The characteristics show the pattern of “single circle” high and low level of “two wings”, and the “one circle” and “two wings” have formed the pattern of single layer and single circle respectively. The spatial differences in economic development level of the counties are significant, but the overall spatial differences decrease gradually. The Moran scatter diagram shows that there are many counties in the first and the third quadrant, indicating that the number of counties with spatial heterogeneity is small and the spatial distribution is uneven During the period, the types of agglomeration in some counties changed, but the overall pattern of county distribution of “Gao Gao” and “Xiao Dao” did not change much.
