摘要: 随着新型城镇化的推进,土地利用方式进入转型期,深入分析土地利用多宜性可为科学土地利用布局提供理论支持。以江苏省55个县域为研究对象,从生产-生活-生态3个维度构建国土空间“三生”功能识别体系,借助GIS空间分析、空间计量模型探析江苏省县域“三生”功能的空间格局特征,结合地理探测器和双变量空间自相关方法揭示关联性,并根据主导功能差异提出优化对策。结果表明:(1)江苏省生产-生活-生态功能用地空间分异明显,呈现以南京、苏州、无锡为主导的生产空间,环洪泽湖、沿海、依山的生态空间和以城镇为中心的生活空间集聚特征;(2)区域经济发展水平、生活承载能力、生态因素共同驱动“三生”功能空间格局,各因素间存在明显的强度差异和空间异质性,经济发展-生活承载驱动、生态保育-生活提升驱动、农业生产-生活发展制约、经济发展-生活承载制约4种类型机理各异并呈现自东南向西北渐变特征;(3)依据生产-生活-生态三大维度功能在不同空间的强弱主次特征确定了生产-生活主导功能区、生产功能主导辅以生活功能提升区、生态功能为主导限制生产功能区、生产功能主导生态功能培育区四类功能区,并以强化生产生活功能凝聚力及保育生态功能为逻辑主线,分析总结其对应的土地利用策略。研究结果不仅可明确江苏省各县域单元的土地利用功能定位,也是优化主体功能区划及合理调控区域功能结构的理论补充和实践参考,为提升区域可持续发展能力提供了科学依据。

Abstract: Land use mode has entered a transitional period as new urbanization advances, and an in-depth analysis of land use versatility can provide theoretical support for scientific land use layout.Taking 55 counties in Jiangsu Province as the research object, the three-dimensional functional recognition system of land-based space was constructed from the three dimensions of production-life-ecology. The spatial pattern characteristics of the “production-living-ecological” function in the county of Jiangsu Province were analyzed by means of GIS spatial analysis and spatial econometric model. It was a way that combing geo-detector with bivariate spatial autocorrelation method to reveal the mechanism of action, and optimization strategies proposed based on the difference of dominant functions.The results showed:(1)The spatial distribution of production-life-ecological function land in Jiangsu Province was obvious, showing that production space dominated by Nanjing, Suzhou and Wuxi city, ecological space surrounded by Hongze Lake, coastal and closed to the mountain and the agglomeration characteristics of living space centered on towns and cities.(2)The regional economic development level, living carrying capacity and ecological factors jointly drived the spatial pattern of the “Sansheng” function. There were obviously intensity differences and spatial heterogeneity among the influencing factors. The four types of influencing mechanisms listed as economic development-life carrying influence, ecological conservation-life promotion influence, agriculture Production-life development restriction, economic development-life bearing restriction were different and appeared from southeast to northwest.(3)On the one hand, according to characteristics of strength, weakness,primary and secondary in different spaces of three dimensions features of production, life and ecology determined the four functional areas,which respectively was production-life domination function area, production dominated with life promoted function area, ecological dominated with production restricted function area and production function dominated with ecological cultivated funtction area. On the other hand, through strengthening production living function cohesion and conservation ecological function as the main line of logic, finally corresponding land use strategies summarized.The research results not only clarify the land use function location of every county unit in Jiangsu Province, but also provide a theoretical basis and practical reference for optimizing the main function zoning and rationally regulating the regional functional structure, and also provide a scientific basis for improving the capacity of regional sustainable development.
