Research On The Stress Restoration Of Residential Landscape Environment On People Based On Physiological Data

In recent years,with the rapid development of cities,the living pressure of urban people is increasing day by day.The outbreak of COVID-19 since 2019 has caused serious problems to people’s basic necessities of life.Working and living on the front line at two points every day,the accumulated pressure is difficult to be relieved timely and effectively.At the same time,the huge impact of the epidemic puts forward new requirements on how to effectively deal with the post impact of major public health emergencies in China.As the primary green space for people’s daily contact,the public green space in residential areas will become a high-frequency space for crowd activities in the face of sudden public health events,and it is also an important place for people to relieve pressure.In recent years,residential space environment design based on restorative perspective has attracted more and more attention,but the total amount of research is less.Therefore,it is of great significance to explore the construction of restorative environment in residential landscape design.The research introduces the concept of physiological recovery,and based on the theory of restorative environment and the physiological and eye movement indexes collected in the experiment,explores the independent and interactive effects of environmental factors of different types of residential space on Residents’ physiological recovery,and analyzes its influence mechanism.Based on the research results,the residential area in the East District of Yicheng,which is lack of space restoration,is transformed,and the Countermeasures of residential environment optimization are put forward.The main results of the study include:(1)Form a set of scientific evaluation methods of spatial environmental resilience:combined with the characteristics of eye movement response and physiological feedback of subjects watching spatial landscape pictures of residential areas,summarize the overall evaluation idea of "pressure guidance-pressure recovery-Environmental resilience evaluation".Through the verification means of the combination of subjective and objective indicators,the experimental results are analyzed in detail.(2)Different typical spaces in residential areas have different effects on people’s stress recovery: the study found that each typical space has a positive effect on people’s physiological and psychological recovery,and the order of spatial recovery is: recreational space > Sports Space > square space.The element of "people" can significantly enhance the restorative role of the square space environment.(3)Different elements in the space have different contributions to the impact of residents’ stress resilience:In the open space and square space,the spatial Green Vision rate and element richness have a positive correlation with the restoration of spatial environment.Among them,the critical values of green visual rate of open space and square space are 46.92% and 50.57% respectively.On this base,the higher the index of spatial Green visibility,the stronger the restorative effect of space,and the index of green visibility has a greater impact on the restorative effect of recreational space than square space;In the open space and square space,the critical values of landscape element richness are 0.0296 and 0.0415 respectively.On this base,the higher the richness index of landscape elements,the stronger the restorative effect of space.There is no significant correlation between spatial Green Vision rate and element richness and the restorative effect of space.(4)The difference of visual preference in different typical space elements: in the rest space and square space,the rich forms of pavement,sketches or elements related to the type of decompression activities,as well as the pleasing colors of arbor and shrub plants(duying,loquat,Phnom Penh boxwood,etc.)are the elements with strong attraction and good visual tolerance;In the sportable space,the elements with good eyesight are single pavement,sports facilities and close-up evergreen trees(green concrete pavement,fitness facilities,camphor).(5)Typical elements of different spaces:Elements related to decompression pathway(pavilions or facilities for sports),pavement and service facilities(garbage cans,seats,etc.)have good restorative effects in the rest space and movable space;In the square space,service facilities(vending machines,seats,etc.)and prospective plants have good recoverability.The study found that the element of architecture is a significant positive recovery element in the recreational space,while it is a significant negative element in the movable space and square space,which shows that in the recreational space,people prefer the space type with strong sense of enclosure and good privacy,while in the movable space and square space,people prefer the open space type.(6)The study found that different types of people have different perceptions of spatial restoration.The rest space has a good effect on the pressure recovery of middle pressure people under the age of 50,students and freelancers;Exercise space has a good effect on the pressure recovery of high-pressure people aged 20 ～ 30 and 50 ～ 60 who work stably;Square space has a good effect on the pressure recovery of people under the age of 20,30 ～ 40 and 50 ～ 60.
