摘要
借助MapInfo7.0平台及其二次开发语言MapBasic对山东省108个县市的人口分布及其空间相关性进行了研究,结果表明:1995-2006年间,山东省各县市人口分布的不均衡指数和集中指数分别由0.0178和0.1306增长到0.0198和0.1454,人口稠密区和人口稀疏区的密度差在不断增大;人口密度分布呈现显著的全局空间集聚模式,1995-2001年为集聚趋势减弱阶段,2001-2004年为集聚趋势增强阶段,2004-2006年又为减弱阶段;4种局部关联类型的分布具有较好的空间结构性,呈现"西南-东北"模式,人口密度分布呈正相关的县市数量明显多于呈负相关的数量。
Population distribution and spatial autoeorrelation of 108 cites and counties in Shandong province were studied with MapIn- fo7. 0 software and MapBasic language. The results showed that population structure indexes from 1995 to 2006 were increasing, indicating the development situation in 1995-2006 ; the population density distribution presented significant phenomena of spatial clustering in the study area, which was weakened in 1995-2001 and enhanced in 2001-2004 and weakened again in 2004-2006; local Moran＇ s I was useful for decomposing the pattern of spatial association into four categories, which have obvious regularity in terms of spatial distribution. It formed a southwest- northeast model. There are more spatial positive correlation than negative correlation between all cities and counties.
