基于MCR模型的村庄“三生空间”格局优化研究

Research on the Spatial Pattern Optimization of Production-Living-Ecological Spaces in Village Based on MCR Model

探究村庄"三生空间"布局的重构与优化,以空间理念研究村庄布局,对推动城乡一体化进程、加快乡村转型及实现乡村振兴具有重要意义。运用GIS软件功能和MCR模型分析等方法研究内蒙古和林格尔县迭力素村国土空间开发利用的适宜性分区及村域"三生空间"格局优化问题。结果表明:(1)迭力素村空间适宜性以圈层呈现,中心位置建设适宜性最佳,生态适宜性由中心向四周逐渐增强,周边生态适宜性较好。(2)根据MCR模型模拟结果将村域国土空间适宜性划分为5种类型,分别为:生态保护区、生态优化区、禁止开发区、限制开发区和适宜开发区。(3)基于功能重要性、生态敏感性原则,兼顾土地利用类型和适宜性评价结果,将生态保护区确定为生态空间;将生态优化区、禁止开发区和限制开发区确定为生产空间;将适宜开发区确定为生活空间。(4)结合村庄发展定位及内部要素,提出生态空间重功能、生产空间重规模、生活空间重品质的迭力素村"三生空间"格局优化途径。研究可为村庄规划的编制提供理论依据。

Exploring the reconstruction and optimization of the village layout in production-living-ecological spaces and studying the village layout with the spatial concept are of great significance to promote the process of urban-rural integration, accelerate rural transformation and realize rural revitalization. GIS software and MCR model analysis were used to study the suitability zoning of land space development and utilization and the pattern optimization of production-living-ecological spaces in Dielisu village, Helinger County, Inner Mongolia. The results show that:(1) the spatial suitability is presented by ring structure in Dielisu village, the construction suitability is the best in the central part, the ecological suitability gradually enhances from the center to the surrounding, and the surrounding ecological suitability is better;(2) the village spatial suitability is divided into 5 types such as ecological protection zone, ecological optimization zone, prohibited development zone, restricted development zone and appropriate development zone according to the simulation results of MCR model;(3) the ecological reserve is determined as ecological space;the ecological optimization zone, prohibited development zone and restricted development zone are designated as production space;the suitable development zone is identified as living space based on the principles of functional importance, ecological sensitivity and taking into account the evaluation results of land use types and suitability;(4) the optimization approach of production-living-ecological space patterns in Dielisu Village is proposed, which focuses on function in ecological space, scale in production space and quality in living space combining with the development orientation and internal elements of the village. This research can provide a theoretical basis for the compilation of village planning.
