城市广场小型景观水体对人体健康的影响

Impact of Urban Square Small-scale Waters on Human Health

近年来,城市水体对人体健康的影响受到研究者的广泛关注。为进一步研究城市小型景观水体对个体身心状态的影响,文章设计不同水体面积(20%、5%、0)城市广场空间中的多个个体静态体验对比试验,分析受试者的生理(血压、心率)、心理(心境状态、主观恢复)和神经情绪指标(挫败、情绪效价和冥想)变化。结果表明:与无水广场空间相比,具有小型景观水体特征的城市广场空间(蓝色空间)可以有效促进个体身心恢复,降低心率、血压,改善情绪纷乱和挫败情绪;蓝色空间中水体面积占比与其对健康的促进作用具有一定相关性,仅水体面积占比20%的蓝色空间具有促进个体积极情绪及放松冥想情绪的作用。根据试验结果,提出城市蓝色空间的健康促进机制与设计策略。

Recently,the effects of urban water space on human health have raised wide attention.In order to study how urban small-scale water influences the physical and mental state of individuals,the paper designs the comparative experiments of individuals’static experience in urban squares with different scales of water(20%,5%and 0),to analyze the changes in physiological(blood pressure,heart rate),psychological(mood state,subjective recovery)and neural emotional indicators(frustration,emotional valence and meditation).The results demonstrate that,compared with the waterless square,the urban square with small-scale water(blue space)can effectively promote health recovery,reduce heart rate and blood pressure,and improve emotional confusion and frustration.In addition,there is a correlation between the size of water in blue space and its health improvement effect.In particular,the blue space with 20%water area can promote emotional valence and meditation of individuals.Based on these results,the health improvement mechanism and design strategy of urban blue space are put forward.
