摘　　要：【目的】在健康城市建设背景下,为了鼓励健康行为、提升绿化的健康效益,急需解决不合适的绿化遮挡对行为决策(生活设施使用、步行和绿地游憩等)的负面影响。【方法】针对成都市三道街改造实践,通过眼动和行为实验探讨具体行为决策场景中,街道绿化多但行为发生不足的原因及行为决策影响机制。【结果】行为决策结果显示:降低遮挡和调整布局的绿化改造策略,不仅保障了绿视率,而且显著促进了设施使用、绿地游憩、步行意愿。佐以眼动证据发现,在设施使用决策中,沿路地面绿化改造通过增强行为任务目标要素(附属商业功能设施、沿街建筑界面等)的可见性来提升决策意愿;绿地游憩和步行活动也支持类似的结论。【结论】综上所述,街道精准绿化改造应构建街道视线窗口,避免底层灌木对活动关键区域造成视线遮挡。此外,除了注重空间品质,街道实际健康效益还必须考虑健康行为发生频率的重要性。[Objective]In the context of health city construction,it is urgent to mitigate the negative impact of inappropriate greening on the use of living facilities,walking,recreation in green space,etc.,so as to enhance the health benefits for citizens.Based on the renovation practice of Sandao Street in Chengdu,this research further discusses the following questions:How to rationally rearrange green spaces and functional spaces of pedestrian streets to balance the aesthetics and functionality thereof?To what extent can the increasing area of green spaces in streets affect people’s decision-making on health-related behaviors?Can we maintain a high proportion of green spaces while optimizing functional spaces for walking,living facilities,green space recreation,etc.?If so,what principles should be followed in street greening arrangement?[Methods]Based on the renovation practice of Sandao Street in Chengdu,this research,through eye movement behavior experiment,discusses the reasons and influencing mechanism for the formation of current street space pattern of excessive green spaces but insufficient functional spaces.Combining the behavioral intervention ladder and the eye movement experiment,the research explores the influence of visual attention on people’s choice of living facilities beneficial to health.The first step is to verify what environmental information can attract people’s attention in specific behavioral scenarios(use of living facilities,walking,recreation in green space,etc.).Second,will people be attracted by any environmental information show interest and preference for it?Third,how do people’s differences in interests and preferences affect their final decisionmaking on health-related behaviors?Based on the behavioral intervention ladder theory,the experimental measurement of behaviors supported by eye movement can be divided into three parts.On the premise of controlling the proportion of green spaces in the environmental exposure,attention,interest and action can be measured separately.Attentio
