近期，北大团队和山大团队基于SGSS数据在重要期刊Water发表论文《城市蓝色空间质量提升与居民健康：来自中国青岛的证据》。

文章指出，城市蓝色空间（UBSs）在维护生态完整性和公众健康方面发挥着关键作用，但水质改善程度与特定健康结果之间的因果机制仍未得到充分探索。研究探讨了河流污染清理计划与海岸线和河口监测计划这两项大规模地表水质量举措对中国青岛市居民健康和身体活动模式的影响。该研究采用准实验双重差分（DID）框架，结合重复的横断面调查数据（2017年和2018年；n=735），评估了其对自评健康（SRH）、幸福感、身体活动水平和体重指数（BMI）的影响。结果显示，两项计划均显著提高了锻炼频率。河流污染清理可使5分制的自评健康得分提高0.319分（β=0.319，p<0.05），而海岸线质量监测计划使5分制的幸福感得分提高0.233分（β=0.233，p<0.05）。相比之下，这两项干预措施对体重指数均无显著影响（p>0.1）。亚组分析表明，水质改善带来的健康和福祉益处因性别、年龄、教育程度和收入水平而异。这些研究结果强调，在退化的城市地区优先实施高效的城市蓝色空间干预措施，并将其与便捷的基础设施相结合，以更有效、更公平的方式优化健康收益具有重要意义。

摘要：Urban blue spaces (UBSs) play a pivotal role in supporting ecological integrity and public health, yet the causal mechanisms connecting the magnitude of water quality improvements to specific health outcomes remain insufficiently explored. The objective of the study is to investigate the effects of two large-scale surface water quality initiatives on the health and physical activity patterns of residents in Qingdao, China: a river pollution clean-up program and a shoreline and estuary monitoring program. Employing a quasi-experimental difference-in-differences (DID) framework with repeated cross-sectional survey data (2017 and 2018; n = 735), we evaluate effects on self-rated health (SRH), happiness, physical activity levels, and body mass index (BMI). Results reveal that both programs significantly enhanced exercise frequency. River pollution clean-up could promote SRH by 0.319 points on the 5-point scale (β = 0.319, p < 0.05), while shoreline quality monitoring program boosted happiness by 0.233 points on the 5-point scale (β = 0.233, p < 0.05). In contrast, both interventions had no significant effect on BMI (p > 0.1). Subgroup analysis revealed that the health and well-being benefits of water quality improvements varied by gender, age, education, and income level. These findings emphasize the importance of prioritizing high-impact UBS interventions in degraded urban areas and integrating them with accessible infrastructure to optimize health gains in a more effective and equitable way.
