摘要

背景:有人指出,与眼睛齐平的绿色街景促进了休闲步行,这是一种对健康有益的体育活动。以前的大多数研究都集中在眼睛水平的街景中的绿化总量,以调查其与步行行为的关系。尽管人们承认,与草坪和灌木相比,较高的树木有助于营造更绿色的环境,提供更高的身体和心理舒适度,但对专门关注绿化高度的街景指标的研究在很大程度上仍未得到探索。因此,本研究从行人的角度考察了按高度分类的街道绿化客观指标与休闲步行时间之间的关系。方法:在日本仙台市的一个城市地区,我们使用谷歌街景图像以50米为间隔创建了街道绿化的街景指数。根据以观众为中心的虚拟半球的纬度,这些指数被分为四个范围。然后,我们调查了他们与自我报告的休闲散步的关系。结果:高位街道绿化与休闲步行时间呈正相关,低位街道绿化与步行时间无显著相关性。结论:研究结果表明,高位绿化丰富的街道可以促进居民的休闲步行,表明高位绿化有助于形成热舒适、美观的街景,从而促进休闲步行。增加较高位置的绿化数量可能会鼓励居民增加休闲散步的时间。

Effects of greenery at different heights in neighbourhood streetscapes on leisure walking: a cross-sectional study using machine learning of streetscape images in Sendai City, Japan.

Background: It has been pointed out that eye-level greenery streetscape promotes leisure walking which is known to be a health -positive physical activity. Most previous studies have focused on the total amount of greenery in the eye-level streetscape to investigate its association with walking behaviour. While it is acknowledged that taller trees contribute to greener environments, providing enhanced physical and psychological comfort compared to lawns and shrubs, the examination of streetscape metrics specifically focused on greenery height remains largely unexplored. Therefore, this study examined the relationship between objective indicators of street greenery categorized by height from a pedestrian viewpoint and leisure walking time.

Methods: We created streetscape indices of street greenery using Google Street View Images at 50-m intervals in an urban area in Sendai City, Japan. The indices were classified into four ranges according to the latitude of the virtual hemisphere centred on the viewer. We then investigated their relationship to self-reported leisure walking.

Results: Positive associations were identified between the street greenery in higher positions and leisure walking time, while there was no significant association between the greenery in lower positions.

Conclusion: The findings indicated that streets with rich greenery in high positions may promote residents' leisure walking, indicating that greenery in higher positions contributes to thermally comfortable and aesthetic streetscapes, thus promoting leisure walking. Increasing the amount of greenery in higher positions may encourage residents to increase the time spent leisure walking.
