不同健康影响路径下的城市绿地空间特征

基于文献梳理,从减少健康风险暴露、促进健康行为活动和提高心理恢复能力3方面讨论城市绿地与公共健康关联的基本路径,针对不同健康影响路径归纳总结分布格局特征、周边联系特征、内部环境特征3类城市绿地空间特征和实证变量指标,分析各项空间特征的健康促进效益。从规划设计实践需求角度提出未来的研究需要从权衡主导风险影响、构建高线指标要求、深化微观促进机制、优化指标度量视角等方面予以完善,以期为健康导向的绿地规划设计提供依据,推进健康绿地循证设计。

Spatial Characteristics of Urban Green Space under Different Health Impact Pathways

Based on recent literature, this paper discusses three public health impact pathways of the urban green space, including reducing health risk exposure, promoting healthy activities and improving psychological restorativeness. Then, it explores the spatial characteristics of urban green space with their variables in empirical studies under different pathways to impact public health in three dimensions: distribution pattern characteristics, peripheral contact characteristics, and interior environment characteristics. It analyzes the benefits of these spatial characteristics to promote public health. The paper concludes with further research directions including trade-off dominant healthy risks, proposing higher requirements for healthy indicators, deepening researches on the promotion mechanism in the micro scale, and optimizing variables measurement, so as to provide references for healthy-oriented urban green space planning and promote evidence-based design for healthy green space.
