公共健康视角下美国社区绿道发展研究

美国社区绿道为提升民众公共健康发挥了重要作用。依据美国社会发展时间脉络与健康诉求，梳理了社区绿道5个发展阶段：发挥自然疗愈、激发社区活力、保障交通安全、促进体力活动、实现生态服务，归纳了不同阶段的社区绿道发展特征，总结了社区绿道发展规律。研究表明，美国社区绿道选线由依托自然资源到塑造人工自然，空间形态由单一线性到网络化覆盖，健康诉求由单一个体健康到个体、社会及生态复合健康，建设模式由政府主导到公众参与。研究旨在促进“健康中国”背景下的社区绿道建设。

Evolution of American Community Greenways from the Perspective of Public Health

American community greenways play an important role in improving public health. Based on the social development context and health demands of the United States, this study identified five development stages of community greenways: developing natural healing, creating community vitality, ensuring traffic safety, promoting physical activity, and realizing ecological services. The development characteristics of the different stages and the development rules for American community greenways were summarized. The results showed that American community greenways have changed from relying on natural resources to creating artificial natural spaces, from single linear spaces to network coverage, from a focus on individual health to a combination of individual, social, and ecological health, and from the government-led construction mode to public participation. The aim of this study is to promote the construction of community greenways in the context of "Healthy China".
