摘　　要：社区绿色空间对促进居民身心健康具有重要意义,是良好人居环境质量的主要表征。从主观意识—客观物象交互视角切入,基于交通可达性、视觉可见性和服务吸引力3个维度,构建社区绿色空间可用性评估模型,可视化其空间分布,识别影响可用性的主要障碍因子,通过对重庆市渝中区两上片区(两路口街道和上清寺街道)进行实证分析。结果表明:(1)绿色空间可用性有显著的空间分异格局,沿大规模高密度的绿色空间向外逐层衰减,局部位置交错分布;(2)吸引力是影响绿色空间可用性的主导维度,可达性和可见性具有强化绿色空间可用性的作用;3个维度在空间分布上均存在一定程度的不均衡性;(3)绿色空间可用性不仅受到绿色空间规模、类型和位置的协同作用,还受到地形、视野、可进入性等多重因子的影响。最后形成多维度联合—多因子协同—多类型统筹的“菜单式”的社区绿色空间可用性优化路径,以期促进绿色空间的实际获得感,提升居民生活的满意度和幸福感。Community green space play a vital role in promoting residents’physical and mental health,serving as a key indicator of a high-quality living environment.From the perspective of subjective-objective interaction,this paper develops an evaluation model for community green space availability based on three dimensions:transportation accessibility,visual visibility,and service attractiveness.It visualizes the spatial distribution of green space availability and identifies the main obstacle factors affecting availability in Liang-Shang area(Lianglukou and Shangqingsi sub-districts)of Yuzhong District,Chongqing.The paper reveals three key findings.First,green space availability presents significant spatial heterogeneity,characterized by a layered attenuation pattern radiating outward from large-scale,high-density green spaces,with localized interlaced distribution.Second,service attractiveness is the dominant dimension affecting availability,while transportation accessibility and visual visibility play reinforcing roles.All three dimensions demonstrate varying degrees of spatial imbalance.Third,green space availability is not only affected by the synergistic effect of green space size,type,and location,but also affected by multiple factors such as topography,field of view,and accessibility.Finally,it proposes a“menu-style”approach for improving community green space availability,which integrates multi-dimensional coordination,multi-factor synergy,and multi-type integration,in order to enhance the tangible benefits derived from green spaces while improving residents’life satisfaction and well-being.
