摘要
绿地与城市功能空间具有交互促进或抑制的作用关系,该作用的空间形式及强度演化规律仍有待揭示。在15分钟生活圈和斑块尺度,借助规划与土地部门的土地利用数据,利用经验贝叶斯验证的空间自相关和MPI、MNN指数,对南京主城区2004、2012、2017年绿地与城市功能空间的空间关联水平进行探究。结果表明:①绿地与各功能空间的数量分布具有一定相斥性,强弱分化逐步加剧。②在15分钟生活圈尺度,绿地与水域、交通、居住的整体空间相关性最强,与水域、交通的关联性持续较强,与居住则具有一定滞后性。绿地与各功能空间形成绿地核心区、城市核心区和一般发展区。③在斑块尺度,绿地与交通、居住、水域、商服的空间聚集性突出,与交通的关联性持续加深加强,其余则有先减弱后增强的趋势。成果可深化绿地与城市空间交互作用理论,为绿地与城市功能空间的高效协同发展、宜居美好生活环境的营造提供科学依据。
Green space and urban functional space have an interactive promotion or inhibition relationship.The spatial form and intensity evolution of this effect remains to be revealed.Based on the land use data,the spatial correlation between green space and urban functional space in Nanjing's main urban area in 2004,2012 and 2017 was explored by using spatial autocorrelation indicators adjusted by empirical Bayes,MPI and MNN index from the scale of 15-minute living circle and patch.The results show that:①The quantitative distribution of green space and functional spaces has a certain repulsion,and the strong and weak differentiation is intensified.②At the scale of 15-minute living circle,green space has the strongest overall spatial relevance to watersheds,transportation and residences.The correlation with watersheds and transportation is strong continuously,while the residential area has a certain lag.Green space and functional spaces form the green core area,urban core area and general development area.③At the patch scale,the spatial aggregation of green space with transportation,residential,water area,and commercial services is prominent.The correlation with traffic continues to deepen and strengthen,and the rest tends to weaken first and then strengthen.The results can deepen the theory of interaction between green space and urban space,and provide a scientific basis for the efficient and coordinated development of green space and urban functional space,and the construction of a livable and beautiful living environment.
