摘　　要：目的探讨空间分析中集中趋势统计指标的计算方法及应用价值。方法以频率统计学中集中趋势的统计指标为基础,借鉴犯罪学中犯罪事件的二维描述方法,系统地提出了空间分析中描述集中趋势的统计指标,并对实际资料进行分析,介绍其应用价值。结果得到了空间分析中描述集中趋势的常用统计指标的计算公式、应用条件及潜在的应用价值。结论空间分析中描述集中趋势的二维统计指标可以作为频率统计学统计描述的有利补充,二者的结合能更全面地描述空间数据。Objective To discuss the computational methods and applications on the statistical indices of central tendency for spatial analysis. Methods Borrowing the ideas from descriptive analysis in the classical statistics and crime incidents, we put forward the methods to compute statistical indices on describing central tendency for spatial analysis, and introduced the application with the data of acute schistosomiasis from 2001 to 2006 in Guichi District, Chizhou City, Anhui Province. Results The computational methods, application conditions and potential values on using these statistical indices to describe the central tendency for spatial analysis were systematically established and introduced. Conclusion Statistical indices on describing the central tendency of spatial analysis were valuable complements for classical statistics, and their combined application would provide more comprehensive description on spatial information.
