运用空间统计学方法对我国各省(自治区、直辖市)奥运奖牌的空间分布格局做空间自相关分析(spatial autocorrelation)。全局Moran’s Ⅰ表明,我国各省(自治区、直辖市)奥运奖牌分布格局的总体变化趋势虽然出现波动,但是,在大部分年份的地域差异不太明显,省际间的空间相互作用不强,呈现随机分布状态,直至2004年才开始表现出集聚的情况,并且呈现空间自相关关联性减弱的趋势。Moran散点图和LISA集聚图进一步揭示了各省(自治区、直辖市)奥运奖牌分布的空间变化以及对总体趋势的偏移。
By means of spatial statistics,this paper makes spatial autocorrelation analysis of Chinese Olympic medals spatial distribution in each province.Global Moran’s Ⅰ showed that the overall trend of distribution pattern of China’s provinces has fluctuations,but in most years less obvious regional differences,inter-provincial spatial interaction was not strong,showing a random distribution,until 2004 only the situation began to gather to show and present spatial autocorrelation correlation weakening trend.Moran scatter plot and LISA cluster map further revealed the spatial distribution of the provinces Olympic medal on the overall trend of change and shift.
