【摘要】：农地整理中的权属调整是缓解耕地破碎化最有效的工具之一,对农民意愿的忽视以及调整方法的不合理却阻碍着权属调整的推广。该研究以江西省黄玲乡农地整理项目为例,采用线性规划运输模型,以满足农户意愿为目标,进行权属调整,并将其与传统调整方法进行了比较。结果显示,基于线性规划运输模型的权属调整能够使地块数量减少71.71%,使地块与农居点距离减小7.16%,使75.04%的农民调整后的地块保留在调整前集中所在的田块,并在以上3方面以及调整精度上均优于传统方法;但是在减小地块分散程度上劣于传统方法;在调整效率上则与传统方法在不同阶段各有优劣。研究认为,基于线性规划运输模型的权属调整能够在缓解耕地破碎化的同时,最大程度地满足农民的意愿,具有良好的应用价值。目前,丰富权属调整方法体系,根据项目条件和农民偏好选择合适的方法,是促进权属调整大规模推广的有效途径。
[Abstract]:The adjustment of ownership in farmland consolidation is one of the most effective tools to alleviate the fragmentation of cultivated land. The neglect of farmers' will and the unreasonable adjustment methods hinder the extension of ownership adjustment.Taking Huangling Rural Land consolidation Project in Jiangxi Province as an example, a linear programming transportation model was used to adjust the ownership of the farm households with the aim of satisfying the farmers' wishes, and compared with the traditional adjustment methods.The results show that the ownership adjustment based on the linear programming transport model can reduce the number of plots by 71.71, reduce the distance between plots and agricultural settlements by 7.16, and keep 75.04% of the adjusted plots of land in the fields where they were concentrated before the adjustment.It is superior to the traditional method in the above three aspects and the adjustment precision, but it is inferior to the traditional method in reducing the dispersion degree of the plot, and the adjustment efficiency is different from the traditional method in different stages.The study shows that the property right adjustment based on linear programming transportation model can alleviate the fragmentation of cultivated land and satisfy the wishes of farmers to the greatest extent. It has good application value.At present, enriching the system of tenure adjustment methods and selecting suitable methods according to project conditions and farmers' preferences is an effective way to promote the large-scale extension of tenure adjustment.
