空间点模式分析中离散趋势的描述研究及应用

Study and Application on the Statistical Indices to Describe the Tendency of Dispersion in the Spatial Point Pattern Analysis

目的探讨空间点模式分析中描述离散趋势的统计指标的计算方法及应用价值。方法借鉴经典统计学中描述离散趋势的统计指标思想和犯罪学中犯罪事件的描述性分析方法,提出了空间点模式分析中描述离散趋势的常用统计指标,并以2001～2006年安徽省池州市贵池区的急性血吸虫病例为例,介绍其应用价值。结果获得了空间点模式分析中描述离散趋势的常用统计指标的计算方法、应用条件及应用价值。结论空间点模式分析中描述离散趋势的统计指标可以作为经典统计学统计描述的有利补充,二者结合能更完整地描述空间数据。

Objective To discuss the computational methods and applications on the statistical indices for the tendency of dispersion in the spatial point pattern 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 the tendency of dispersion in the spatial point pattern analysis,and introduced their applications with the data of acute schistosomiasis from 2001 to 2006 in Guichi District,Chi...
