基于MCR模型的村域土地整治分区研究——以左云县南辛窑村为例

为因地制宜进行土地整治，实现土地空间布局优化，本研究以山西省左云县南辛窑村为例，从全域土地整治视角，运用MCR模型和GIS软件结合的方法分析村域土地资源利用功能适宜性，依此划定土地整治分区，结合村庄规划定位提出相应的土地整治发展策略。结果表明：MCR差值≤0表示生态适宜性较强，差值>0表示建设适宜性强，按照MCR差值由高到低的顺序依次确定土地利用适宜性方向；在国土空间规划“三线”约束下，将研究区划分为小杂粮生产示范区、林草生态保护区、工业生产开发区、宜居核心整治区4类整治区，面积分别为232.02、529.14、5.85、5.88 hm²。整治分区后的土地资源分布格局呈现圈层夹散点的布局结构，具有明显的空间差异性，生态适宜性由中心向四周逐渐增强，与当地生态环境本底相吻合。研究表明，应用MCR模型实施土地整治分区，符合集聚提升型村庄发展要求，实现了耕地集中连片、居住用地集约高效、生态环境充分保护、产业发展有保障的目标，为村庄规划的科学编制和分区土地整治策略提供理论参考。

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.
