摘要
以兴国县村域为单元,从耕地数量、质量和生态三个维度构建指标体系,运用生态位适宜度模型、改进CRITIC法和综合指数法开展耕地“三位一体”综合评价,并分析其空间分异特征。同时,运用三维魔方法划分耕地保护分区,并提出不同的保护利用措施,以期为耕地保护动态监管政策制定和国土空间规划的编制提供技术支撑。
Taking the village area of Xingguo County as the unit,the index system is constructed from the three dimensions of quantity,quality and ecology of cultivated land,and the“trinity”comprehensive evaluation of cultivated land is carried out by using the ecological niche suitability model,the improved CRITIC method and the comprehensive index method,and the spatial differentiation characteristics are analyzed.At the same time,the three-dimensional magic cube method is used to divide the farmland protection zone,and different protection and utilization measures are proposed,in order to provide technical support for the formulation of dynamic regulatory policies for farmland protection and the preparation of land spatial planning.
