Previous literature has examined the relationship between the amount of green space and perceived safety in urban areas, but little is known about the effect of street-view neighborhood greenery on perceived neighborhood safety. Using a deep learning approach, we derived greenery from a massive set of street view images in central Guangzhou. We further tested the relationships and mechanisms between street-view greenery and fear of crime in the neighborhood. Results demonstrated that a higher level of neighborhood street-view greenery was associated with a lower fear of crime, and its relationship was mediated by perceived physical incivilities. While increasing street greenery of the micro-environment may reduce fear of crime, this paper also suggests that social factors should be considered when designing ameliorative programs.
先前的文献研究了城市中绿色空间的数量与感知安全之间的关系，但对于街道景观绿化对感知社区安全的影响知之甚少。本研究使用深度学习方法，从广州市中心的大量街景图像中提取绿化数据。在此基础上，进一步检验了街道景观绿化与邻里犯罪恐惧之间的关系和作用机制。结果表明，较高水平的邻里街道景观绿化与较低的犯罪恐惧相关，这种关系受到感知的物质不文明行为的中介作用。虽然增加微观环境的街道绿化可能会降低犯罪恐惧，但本文还表明，在设计改善计划时应考虑社会因素。
