摘　　要：为深入研究村民关联空间格局的差异性,利用河西走廊15个县(市、区)的调查数据,采用模糊综合评判法测算村民关联的水平,并运用探索性空间数据分析(ESDA)法测评村民关联的空间格局与区域差异。研究结果表明:1)河西走廊地区村民关联水平普遍较低,空间格局差异明显,存在显著的正的空间自相关性。2)河西走廊村民关联具有"点-带-团"状结构特征。村民关联水平较高的县级单元主要处于石羊河流域,形成了分值较高的聚集"点";村民关联较低的疏勒河流域的敦煌市、玉门市、瓜州县形成了低值分布"带";张掖市、酒泉市所辖县形成了村民关联低值"团"。剖析村民关联空间格局的内在机理,为促进不同区域农地制度有效合理变革进而提高农地利用效率,提出保护农地权益的合理化建议提供理论依据和方法参考。The purpose of the study is to explore the differences of the spatial characteristics of tion, based on the survey data of 15 counties in Hexi Corridor. fuzzy comprehensive evaluati villagers＇ correla- on was applied to measure the villagers correlation, and exploratory spatial data analysis was used to determine the spatial charac- teristics and differences. The results show that ： （ 1 ） The villagers correlation is generally low, the spatial charac- teristics are obvious, and there is a significant positive spatial autocorrelation. （2） The villager correlation has ＂ point - corridor - group＂ structure characteristics. Villagers correlation in Shiyang river basin is at high level, and forms ＂point＂ ; that in Dunhuang City, Yumen City, and Guazhou County in Shule river basin is at the low level, and forms ＂corridor＂ ; in counties belonging to Zhangye City and Jiuquan City, villagers＇ correlation is at the low level,and forms ＂groups＂. Exploration of the difference of the spatial characteristics of villagers＇ correla- tion is to promote the reasonable change of land system and improve the efficiency of land use, and to provide theoretical and method references for protecting the farmland rights.
