【摘要】 高密度空间设计引发了诸多与居民健康密切相关的城市问题，休闲性体力活动是新时期重要的健康需求，也是空间主动干预公共健康的有效切入点。为探讨二者的科学关联，文章选取成都市6个高密度社区，在控制个人及社会要素的情况下，利用多元线性回归模型分别探究建成环境要素对散步、中等强度体力活动和高等强度活动的影响。研究结果表明：土地利用混合熵、天空开敞度、街景美观度与散步活动水平呈正相关，土地利用混合熵与中高等强度活动水平呈负相关，活动空间美观性、康体设施密度与中等强度活动水平呈正相关，步行道尺度、商业设施密度与高等强度活动水平呈正相关。并在数据分析的基础上，从路径布局、空间塑造和社交支持3个方面提出优化策略。更多还原

【Abstract】 High-density spatial design has triggered many urban problems that are closely related to residents’ health. Recreational physical activity is an important health demand in the new era, and an effective entry point for spatial active intervention in public health. In order to explore the scientific correlation between the two, the article selects six high-density neighborhoods in Chengdu city, and explores the effects of built environment factors on walking, moderate-intensity physical activity, and high-intensity activity by using multivariate linear regression models, controlling for personal and social factors. The results show that: land use mixing, sky openness, and streetscape aesthetics are positively related to walking, land use mixing is negatively related to moderate-highintensity activity, activity space aesthetics, recreation and sports facility density are positively related to moderate-intensity activity,and walking path scale, commercial facility density are positively related to high-intensity activity. Based on the data analysis,optimization strategies are proposed in three aspects: path layout, space shaping, and social support.更多还原
