摘要/Abstract

摘要： 本文研究了最常用的局部空间自相关指标；局部Moran指数和局部G系数，基于模拟的空间区域；设计了一些有代表性的空间聚集方案进行计算，比较了两种指标的探测结果，得出局部G系数要优于局部Moran指数的初步结论。

关键词: 空间自相关, 局部指标, 局部Moran指数, 局部G系数

Abstract: Abstract:Local Moran＇s Index and Getis-Ord Local G are among the most commonly used indices for the analysis of local spatial autocorrelation.This paper compared local Moran＇s Index and Getis-Ord local G, based on simulating area, analysis the character of local Moran＇s Index and Getis-Ord local G in finding the local spatial autocorrelation. And concluded that local G is better than local Moran＇s Index.

Key words: Key words:spatial autocorrelation, local indices, local moran＇s index, getis-ord local G
