Abstract: Based on the survey data of 15 counties in Hexi Corridor,Gansu Province,China,this paper was to explore the spatial characteristics and influence factors of villagers linkage by firstly using fuzzy comprehensive evaluation to measure the linkage level and then using exploratory spatial data analysis to determine the spatial characteristics and differences.At last,the Geographically Weighted Regression method was applied to analyze the influencing factors.The results showed as follows:(1) The villagers linkage level was generally low with a obviously different 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 significant 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 provided the information in reforming the land use policy and improving the efficiency of land use as well as protecting the farmland rights.
