摘　　要：现今社会竞争日益激烈,青年人的精神压力不断增加。现有研究表明,自然环境对人们的身心健康有着积极的影响,但目前与人们生活密切相关的城市中的自然环境对健康的促进作用研究较为缺乏。通过采集参与者在2段差异性高的滨河实景环境中行走的生理信号和眼动数据,探究不同滨河步道景观下青年人的压力缓解情况和视觉特征。研究结果表明:(1)以SDNN、RMSSD和Lorenz散点图为代表的心率变异性特征(HRV)在不同区段的滨河步道下呈现明显差异,绿化程度高的场景对压力的缓解作用更强;(2)不同场景下的视线特征与压力缓解有一定的关联性,行人的视线多偏向于步道滨水侧开敞度高的空间,经过绿化程度高或有休憩空间的滨河步道场景时,行人的视线更分散,压力缓解效果更佳。将缓解压力作为滨河步道的景观功能之一,通过主动干预有针对性地进行滨河景观类型与植物种植的改造,以期达到更好的滨河步道环境提升效果。Nowadays,with the increasingly fierce social competition,the mental pressure of young people is increasing.Existing studies have shown that the natural environment has a positive impact on people's physical and mental health,but there is a lack of research on the promoting effect of the natural environment on health in cities closely related to people's life.By collecting the physiological signals and eye movement data of participants walking in two sections of highly different riverside real environment,this paper explores the stress relief and visual characteristics of young people under different riverside footpath landscapes.The results show that:(1)the characteristics of heart rate variability(HRV)represented by SDNN,RMSSD and Lorenz scatter plot are significantly different under the riverside footpaths in different sections,and the scenes with high greening degree have a stronger effect on relieving pressure;(2)There is a certain correlation between the line-of-sight characteristics under different scenes and pressure relief.The line of sight of pedestrians mostly turns to the space with high openness on the waterfront side of the footpath.When passing through the riverside scene with high greening degree or rest space,the line of sight of pedestrians is more scattered and the pressure relief effect is better.The paper takes pressure relief as one of the landscape functions of waterfront trails,and carries out targeted transformation of landscape types and plant planting through active intervention,in order to achieve better environmental improvement effect of waterfront trails.
