摘要:

研究从耕地多功能理论和国家发展现实需求出发,构建了耕地多功能解析框架和功能分类评价体系,以土地利用变更调查数据为基础,创建覆盖苏南地区全域耕地的1km×1km空间格网,以此为评价单元,采用模糊优选模型定量评价苏南地区耕地多功能并分析其空间特征。研究结果表明:① 经济发展新常态背景下,耕地功能内涵不断丰富,逐步从基础性的生产功能转向集生产、生活、生态、阻隔、文化功能于一身的多种功能;② 苏南地区耕地农业生产保障功能总体较强,社会生活保障功能西高东低,生态安全维持功能总体偏弱,城镇空间阻隔功能表现突出,苏南地区东部乡土文化承载功能较强;③ 苏南地区耕地多功能区域分异特征显著,具体可分为农业生产主导型、都市农业示范型、特色农业发展型、高效农业建设型、绿色农业观光型5种类型区,各区耕地主导功能均有所差异。研究结果可为推动土地利用分区管制规则制定、土地整治重点区域选择、永久基本农田划定等土地利用实践提供参考。

Abstract:

Based on the theory of arable land multifunction and development demands of China, we created an analytical framework and classification evaluation system to evaluate arable land multifunction. We also created a spatial grid at a resolution of 1 km × 1 km covering arable land of southern Jiangsu based on survey data of land use change. We quantitatively evaluated arable land multifunction and analyzed spatial characteristics in southern Jiangsu using Fuzzy Optimization Modeling. We found that in the context of the new normalcy of economic development, the connotation of arable land multifunction is richer. Arable land function is not mono-functional (i. e. , foundational production function) but composed of multiple functions, containing a production function, living function, ecological function, barrier function and culture function. In southern Jiangsu, grain production guarantee function is generally weak and the social living guarantee function is inferior in the western region. The ecological security maintenance function in southern Jiangsu is generally weak. The urban space barrier function is generally strong. The eastern region is of a high native culture bearing function. The regional differentiation of arable land multifunction was significant in southern Jiangsu. Overall, southern Jiangsu can be divided into five subareas: agricultural production dominance area, urban agriculture demonstration area, characteristic agriculture development area, efficiency agriculture construction area and green agriculture tourism area. These results provide a reference for land use practice, formulating regulatory rules of land use zoning, selecting key areas for land consolidation, and delineating permanent basic farmland.
