摘　　要：为深入研究村民关联的空间格局及影响因素,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,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,并运用地理加权回归(GWR)模型分析村民关联的影响因素。研究表明:(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"。(3)村内因子和村间因子与村民关联都呈显著的正相关关系,空间分异特征明显。村内影响因子的回归系数在空间上从西北向东南方向呈现逐渐递增的趋势,而村间因子形成了河西走廊东部和西部的高值聚集中心,呈现出空间地域上"两头高中间低"的"哑铃"结构。剖析村民关联空间格局及影响因素的内在机理,为促进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。Based on the survey data of 15 counties in Hexi Corridor,Gansu Province,China,this paper was to ex- plore the spatial characteristies and influence factors of villagers linkage by firstly using fuzzy comprehensive evalua- tion to measure the linkage level and then using exploratory spatial data analysis to determine the spatial character- istics and differences. At last, the Geographically Weighted Regression method was applied to cing factors. The results showed as follows ： （ 1 ） The villagers linkage level was generally low analyze the influen- with a obviously dif- ferent d spatial characteristics. There is a significant positive spatial auto-correlation. （2） The villagers linkage has the ＂points-belt-circle＂ structural characteristics. Those counties or county-equivalent places with a high linkage level were mainly located in Shiyang River Basin, constituting those points. Located in Shule River Basic, Dunhuang City,Yumen City, and Guazhou County formed the belt with a low linkage level. The counties under Zhangye City and Jiuquan City composed the circle with a much lower linkage level. （3） The influence factors present a signifi- cant positive correlation with a spatial heterogeneity. The factors within the village showed an increasing trend from the northwest to the southeast. The inter-village factors had made the east and west of Hexi Corridor centers of high linkage level. So a ＂dumbbell＂ shape was formed from regional perspective. Exploring the spatial characteristics and influence factors of villagers linkage ficiency of land use as well as provided the information in reforming the land use policy and improving the ef- protecting the farmland rights.
