摘　　要：以砚山县的村域为研究单元,从时空角度出发,利用2007—2013年农村人均纯收入数据,采用GIS技术与探索性空间数据分析(ESDA)相结合的方法,对研究区农村居民收入的时空演变特征、总体和局部空间格局变化进行分析。结果表明:总体空间集聚性逐步增强,农民收入差距日益扩大;农村经济收入较高的地区主要分布在资源丰富、交通便利,且拥有特色经济、支柱产业的区域;经济收入较低的地区分布在自然条件较差,交通落后的区域;高收入地区和低收入区逐步形成明显的空间两极分化,宏观的空间分异表现为北高南低格局;地理条件、交通状况、农业生产条件及资源承载是造成农村经济发展差异的主要原因。Take the Yanshan village as a case of study, using the 2007--2013 rural per capita net income data to analyze the global and local pattern change of villager income, with GIS technique and exploratory spatial data analysis （ESDA）. The study result shows that the spatial aggregation is increasing generally, while the income gap becomes bigger; the areas with higher rural economic income is distributed among areas with rich resources, con- venient transportation, characteristic economy and pillar industries; and the one with lower income is located in ar- eas with inconvenient transportation and less resources; the polarization has already becomes serious, south is bet- ter than north. Geographical conditions, transportation situation, agricultural production conditions and resources are the main reasons which make the discrepancy of rural economies.
