The role played by urban greenways in supporting physical activity (PA) for public health benefits has been receiving increasing attention. Most studies on this topic have been conducted in plains, whereas studies in mountainous regions have been limited as a result of the complexity of these areas. To address this knowledge gap, this article aims to analyze the effects of the environmental features for a mountainous urban greenway (MUG) on PA, leading to better support for greenway practice in mountainous areas. A volunteered geographic information (VGI) method was applied through the mobile app KEEP to collect 1314 valid records of PA including its density (total PA distance per unit area within the buffer zone) and attributes (distance, duration and speed) in the Yuzhong Peninsula, Chongqing, China. Similar to those of the studies conducted in the plains, our results showed that PA density was affected by the MUG and its surrounding environment. The key environmental features included residential density, open-space POI, the slope, the transportation-MUG (T-MUG) ratio and the recreational-MUG (R-MUG) ratio. For the PA attributes, the MUG showed stronger effects than the surrounding environment. The key environmental features included the slope and type of MUG, of which the former was negatively associated with distance and speed. The T-MUG ratio was positively related to duration and speed, while the R-MUG ratio was positively related to duration and distance. No association was found between livelihood (L-MUG) and PA. Hence, to support both the PA density and attributes, the environmental qualities for recreation and the types of R-MUGs should be given more consideration in practice.
城市绿道在支持促进公众健康的身体活动（PA）方面的作用越来越受到关注。大多数关于这个主题的研究都是在平原地区进行的，而由于这些地区的复杂性，山地地区的研究则有限。为了弥补这一知识空白，本文旨在分析山地城市绿道（MUG）的环境特征对 PA 的影响，从而为山地地区的绿道实践提供更好的支持。通过移动应用程序 KEEP 应用了自愿地理信息（VGI）方法，共收集了 1314 条有效 PA 记录，包括在中国重庆渝中半岛缓冲区的 PA 密度（单位面积内的总 PA 距离）和属性（距离、持续时间和速度）。与平原地区的研究结果相似，我们的研究结果表明，PA 密度受到 MUG 及其周围环境的影响。关键的环境特征包括居住密度、开放空间 POI、坡度、交通-MUG（T-MUG）比和娱乐-MUG（R-MUG）比。对于 PA 属性，MUG 比周围环境具有更强的影响。关键的环境特征包括坡度和 MUG 类型，其中前者与距离和速度呈负相关。T-MUG 比与持续时间和速度呈正相关，而 R-MUG 比与持续时间和距离呈正相关。生计（L-MUG）与 PA 之间没有关联。因此，为了支持 PA 密度和属性，在实践中应更多地考虑娱乐环境质量和 R-MUG 类型。
