摘　　要：研究立足于城市小微绿地空间,借助LiDAR点云技术、无人机航拍监测等技术手段与数学决策分析方法,建构“老年社交行为感知”与其“多维绿视感知”之间的关联性,从而探寻老年人群绿视感知与其社交行为规律,并筛选出影响老年社交行为的关键因子。选取南京10块小微绿地作为案例对象,分析发现:从老年社交层面而言,无论社交时长的长短,均与绿视感知显现出明显的关联变化,且群体性社交行为更容易受绿视感知的影响;从空间层面而言,植被层次、植被紧凑性2项指标为对老年社交感知存在影响的关键因子。In high-density settings,small and micro green spaces have emerged as a key area of research interest.This study investigates the social behavior of the elderly within such spaces,employing advanced techniques such as LiDAR and UAV monitoring for quantitative assessment.It establishes a correlation between the elderly’s social behavior and their multidimensional perception of the green view,thereby exploring the patterns that are influenced by the characteristics of the green view.Through the analysis of ten spaces in Nanjing,the research reveals a clear correlation between the duration of the elderly’s social interactions and their perception of the green view,with group behavior being more influenced.Vegetation hierarchy and compactness are identified as crucial spatial factors that have an impact on the social perceptions of the elderly.Future research could further explore this relationship to unearth an optimal paradigm for fostering the social interaction of the el derly in small and micro green spaces.
