Estimation of land consolidation potential of rural residential areas based on constraint of relocation distance

Estimation of rural residential land consolidation potential is important for land consolidation planning. In order to get the reasonable estimation of the consolidation potential of rural residential areas, a new acculation method of the realistic potential was discussed in this paper. Taking Binyang County, Guangxi Autonomous Region as a case, an improved model of Method of Constructive Land Standard per capita (MCLS) was established in this paper, which used the relocation distance as a constraint. Based on the questionnaires of relocation willingness, the consolidation potential of rural residential areas in Bingyang County in 2020 was calculated by this model. The results showed that: compared with the traditional MCLS, the calculated potential reduced 30.33% while considering the relocation distance, which indicated the significant influences of relocation distance on the land consolidation potential of rural residential areas. Considering the constraint of relocation distance, the relocation areas could be reduced effectively, so as to reduce the compensation of relocation households under the ArcGIS platform. Besides, for the consideration of their behalf, the consolidation was reliable to get support from the local residents. Thus the new model was feasible and promising.
