居民时空行为地理环境暴露的健康效应及机制

The public health effect of geographic environmental exposure is an important field in the interdisciplinary study of geography and public health and medicine. The existing research focuses on the environmental effects of residence or employment places on health, and has some limits to reveal the comprehensive effects of individual spatiotemporal behavior and the related geographical context. From the perspective of individual spatiotemporal behavior, and based on multi-source data, such as residents' daily activities and travel diary, mobile phone, POI and other data, this research will firstly set up the theoretical framework and methods system of public health effect of spatiotemporal geographic environmental exposure. Secondly, it will analyze the characteristics of residents’ geographical environment exposure and health from the perspect of individual and group. Thirdly, it will study on the mechanism of health effect of environmental exposure (including physiological and psychological well-being), explore the groups' diversity of environmental exposure and discuss the related social justice issues. High risk of environmental exposure and health vulnerable groups will therefore be identified. Finally, it will discuss on the ideas and measures of individual-based health service and allocation of social health resources based on spatiotemporal behavior and geographical environment exposure. This research not only enriches the research of healthy geography from the aspect of both theory and method, but also provides scientific basis and empirical evidence for individual behavior decision making, urban construction, as well as medical and health service.

居民地理环境暴露的健康效应是地理学与公共卫生和医学交叉研究的重要领域，已有研究侧重于从居住地或就业地角度探讨地理环境背景对健康的影响，难以揭示个体连续时空行为及其变化的地理环境暴露对健康的综合作用。本研究以城市居民日常活动与出行日志、手机轨迹数据、POI、遥感影像等多源数据为基础，在构建和完善时空行为地理环境暴露健康效应的理论框架与方法的基础上，分析居民时空行为地理环境暴露及健康水平的个体与群体特征；并进一步研究地理环境暴露对健康（包括生理健康和心理健康）的作用机制与内在逻辑及由此产生的地理环境暴露群体差异与社会公正问题，识别高地理环境暴露风险的健康弱势群体；探讨基于时空行为地理环境暴露对居民健康影响的个体主动健康服务与社会健康资源配置等。本研究不仅从理论及方法上丰富了健康地理学的研究内容，同时也为个体行为决策、城市建设及医疗卫生服务等工作提供科学基础及实证依据。

居民地理环境暴露的健康效应是地理学与公共卫生和医学交叉研究的重要领域，已有研究侧重于从居住地或就业地角度探讨地理环境背景对健康的影响，难以揭示个体连续时空行为及其变化的地理环境暴露对健康的综合作用。本研究主要选择广州和粤港澳大湾区为案例，以居民时空行为地理环境暴露为研究主体，以居民健康效应及群体差异为切入点，研究：①时空行为地理环境暴露健康效应的理论框架与方法；②居民时空行为地理环境暴露情况及健康水平；③时空行为地理环境暴露对公众健康的影响；④时空行为地理环境暴露对居民健康影响的群体差异；以及⑤基于时空行为地理环境暴露对居民健康影响的社会健康资源配置等，并拓展相关领域的研究主题。项目围绕既定研究框架开展相关理论与实证研究，并结合开展过程中的实际情况对研究内容进行了适当拓展，完成预期研究目标，执行期挂基金号共发表论文56篇，包括28篇中文和28篇英文（SCI/SSCI）期刊学术论文。本项目同时开展了相关技术方法的研发，共申请/授权国家发明专利5项，登记软件著作权4项。项目组成员参加国内外学术会议50多人次，其中，项目负责人受邀做与本项目主题相关的大会报告或特邀报告24次，组织学术会议或主题论坛6次，指导毕业博士研究生7名，硕士生9名。成果不仅从理论及方法上丰富了健康地理学的研究内容，同时也为个体行为决策、城市建设及医疗卫生服务等工作提供科学基础及实证依据。项目推动了相关领域的发展，并在相关人才培养和促进知识传播和推广应用等方面取得良好的成效。
