Research on village land consolidation zoning based on an MCR model:a case study of Nanxinyao Village,Zuoyun County
The aim of this study was to carry out land improvement according to local conditions,optimize the spatial layout of land,and promote rural revitalization.Using Nanxinyao Village as an example and by considering global village land renovation,a minimum cumulative resistance(MCR)model and GIS software analysis were used to assess the village domain,including the functional suitability of land resources.According to the optimum appropriate sex results,the partitioning of land control was delimited,and corresponding land management strategies were put forward accordingly.Nanxinyao Village,Zuoyun County,Shanxi Province,was taken as an example from the perspective of comprehensive land consolidation.The method of combining MCR modeling and GIS software analysis was used to investigate the functional suitability of land resource utilization in the village.Based on these results,land consolidation zoning was determined and corresponding land consolidation development strategies were proposed in combination with village planning positioning.An MCR difference of≤0 indicated strong ecological suitability,and that of>0 indicated a strong construction suitability.The direction of land use suitability was determined based on the order of MCR difference from high to low.Under the constraints of the"three lines"in national spatial planning,the research area was divided into four types of consolidation zones:an agricultural production and construction zone,forest and grass ecological protection zone,industrial production and development zone,and livable core remediation zone,with areas of 232.02,529.14,5.85 hm2,and 5.88 hm2,respectively.The distribution pattern of land resources presented a structure of circles with scattered points after land consolidation zoning,with obvious spatial differences.The ecological suitability gradually increased from the center to the surrounding areas,which was in line with the local ecological environment.The implementation of land consolidation zoning based on an MCR model meets the requirements of the agglomeration and promotion of village development.It achieves the goals of concentrated and contiguous arable land,intensive and efficient residential land,full protection of the ecological environment,and guaranteed industrial development.The results of this study provide a theoretical reference for evidence-based village planning and zoning land consolidation strategies.
