摘要
为有效评测和破解城市核心区人地矛盾突出问题,文章以南京中心城区为例,构建城市三生空间分类体系,利用土地利用现状数据,借助熵权法、耦合协调度方法,分时段揭示其耦合度、耦合协调度演化规律及时空格局。结果表明:1)三生空间多呈现强作用、中等耦合协调状态,耦合协调程度不断增强,2)空间“两环”格局日渐突出,环明城墙、护城河外围,以及环中心城区边缘逐渐形成三生空间高度耦合协调区域,古城区、大型生态空间是低水平耦合协调和拮抗、低水平耦合的主要区域,3)生活与生态空间的耦合协调水平最高且逐步提升,生产空间与生活、生态空间耦合协调度较低且渐趋下降,4)三生空间由生活-生产功能为中心转型为生活-生态功能为导向的发展模式。
In order to evaluate and solve the prominent contradiction between human and land in city core area,the paper attempts to construct a classification system of urban ecological-production-living space Based on the data on urban land use and the methods of entropy weight and coupling coordination degree are used to reveal the evolution and spatial-temporal pattern of coupling degree and coupling coordination degree in different periods The results show that:1)the ecological-production-living space has a strong effect and medium coupling coordination,with increasing coupling coordination degree,2)Spatially,the“two ring”pattern is increasingly prominent The high coupling coordination area is gradually shaped around the periphery of the city wall built in the Ming Dynasty,moat,and the edge of the main urban area,while the ancient city area and the large ecological space have the low-level coupling coordination,antagonism and low-level areas of coupling,3)The coupling coordination between living space and ecological space is at the highest level and gradually increasing,while the coupling coordination degree of production space and life or ecological space is low and gradually declining at that,and 4)The ecological-production-living space has transformed its development direction from the domination by life and production function to the prioritization of life and ecological function。
