摘要
基于空间自相关分析方法,分析了2003—2008年云南省农民人均纯收入的时空格局演变模式。分析结果显示:2003—2008年期间,农民纯收入在时间尺度上呈现逐年增长模式,在全局空间尺度上呈现很强的正空间自相关性;农民人均纯收入高-高的的区域和低-低的区域始终呈现着显著的空间集聚特征;自2004年以来,农民人均纯收入相似的县其空间聚集程度表现逐年减弱的趋势,但其空间自相关性仍然较高。
Spatial autocorrelation analysis theories are applied to famers＇s per capita income in 126 counties of Yunnan province from 2003 to 2008. The analysis result demonstrates that 2003--2008 period,the famers＇s per capita income in the time scale growth model year by year, and the global spatial scale showed a strong positive autocorrelation ;the famers＇s per capita income in high-high areas and low - low areas always showed a spatial significantspatial clustering features. Since 2004, famers＇s per capita income of the county similar to the degree of spatial aggregation gradually decreasing in the performance of famers＇s per capita income of the county similar to the performance of its degree of spatial aggregation decreased year by year trend, but still high spatial autocorrelation.
