Few studies have investigated relative contributions of the built and natural environments to and their nonlinear associations with leisure physical activity (PA) in different spatial contexts. Applying gradient boosting decision tree models to data comprising 1049 adults collected in Shanghai, we investigated the associations between built and natural environments and leisure PA in residential and workplace neighborhoods. Results show that the built environment is more important than the natural environment to leisure PA in both residences and workplaces. Environmental attributes have nonlinear and threshold effects. Within certain ranges, land use mix and population density have opposite associations with leisure PA in residences and workplaces, whereas the distance to the city center and the area of water are associated with leisure PA in residences and workplaces with the same direction. These findings help urban planners design context-specific environmental interventions for supporting leisure PA.
鲜有研究调查建成环境和自然环境对休闲体力活动（PA）的相对贡献及其在不同空间背景下的非线性关联。本研究应用梯度提升决策树模型，基于在上海采集的包含 1049 名成年人的数据，调查了居住和工作场所邻里的建成和自然环境与休闲 PA 之间的关联。结果表明，在居住和工作场所，建成环境对休闲 PA 的重要性均大于自然环境。环境属性具有非线性和阈值效应。在一定范围内，居住和工作场所的土地利用混合度和人口密度与休闲 PA 呈相反关联，而到市中心的距离和水域面积与休闲 PA 呈相同方向的关联，且这种关联仅在一定范围内存在。这些发现有助于城市规划者为支持休闲 PA 设计特定于情境的环境干预措施。
