Abstract: [Objective]The fragmentation of cultivated land exists widely in the urderdeveloped areas of agriculture, caused by natural factors and the average allocation rule of cultivated land under the household contract responsibility system, restricting the development of agriculture. In order to solve this problem and achieve large-scale production in agriculture, a new method based on hierarchical cluster analysis was proposed to classify and exchange rural plots. [Method]In this study, wenzhuang village of Taigu County in Shanxi Province was taken as an example. Eight factors were employed to evaluate the cultivated land quality, including plot area, slope of land, shape index of plot, continuity of plot, regularity of plot, traffic accessibility, farming distance and plot yield, Through the analysis for those eight factors utilizing rural land ownership database and hierarchical cluster analysis method, the plots were divided into 5 categories according to the characteristic of farmland operation in the area studied. [Result] Research indicates: the same classified plots in wenzhuang village were distributed around residential area in the form of circular circle; on the basis of the right of village collectives’ farmland contract and management, the same classified plots can be exchanged among the farmers of their own accord, and the land management right of the different classified blocks can be adjusted according to the average yield level, through which the land with the same management right can be gather together as much as possible and improve the farming efficiency. [Conclusion]This method is suitable for the interchange of cultivated land inside village collectives and provides a new way for the adjustment
