研究结果表明，街道全景中的绿色与蓝色空间对中国的老年人具有抑郁防护作用，但需通过纵向研究进一步验证因果关系。街道全景数据与卫星遥感提取的绿色和蓝色空间指标反映了自然环境的不同方面。街道全景数据与深度学习技术均为健康相关研究中自动化环境暴露评估的重要工具。

Our findings provide support that street view green and blue spaces are protective against depression for the elderly in China, yet longitudinal confirmation to infer causality is necessary. Street view and satellite-derived green and blue space measures represent different aspects of natural environments. Both street view data and deep learning are valuable tools for automated environmental exposure assessments for health-related studies.
