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。 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.
