Research And Evaluation Of Kuanghe Park Space Environmental Factor Based On Stress Reduction Theory In Hefei

In modern cities,people's pace of life is gradually accelerating.There are also factors such as air pollution,poor housing conditions and noise that have a negative impact on people's health,causing people to experience unprecedented physical and psychological pressure.Many scholars have discussed the positive role of urban park green space in alleviating the mental stress of the crowd,but the spatial pattern of urban parks still has deficiencies in the relief of people's stress.From the perspective of pressure relief theory,this paper explores the mechanism of urban park landscape space environment's promotion of people's mental health through the investigation of urban park users,and establishes an evaluation system.Therefore,subjective perception and objective Hefei Kuanghe Park space environment How to evaluate the connection between them has certain theoretical and practical value.This article takes the Kuanghe Park as the research object,takes the 22 spatial environmental factors extracted as the evaluation indicators,and then uses the Likert scale questionnaire to conduct the research.For the results of the questionnaire survey,using the data analysis software spss23.0,through means analysis,factor analysis,correlation analysis,stepwise regression analysis and single factor analysis of variance,etc.,explore the spatial environmental factors that affect the pressure relief of urban parks and different groups of people Differences in environmental needs.The results of the data analysis are compared:(1)Respondents believe that the restorative environment of urban parks is better and can better relieve mental stress;(2)Among the perceptual factors in the park,"waterscapes with high hydrophilicity","comfortable rest facilities",and "strong viewing facilities" have a significant positive effect on the pressure relief of the crowd.Among the natural factors,"lawn cover "Large area" has a significant positive effect on the pressure relief of the population.(3)Respondents' arrival time,stay time,and stress level will all show significant differences in the urban park stress relief effect.The shorter the time to go to the city park,the better the pressure relief effect;the longer the stay in the park,the better the pressure relief effect;there is a negative correlation between the pressure level and the pressure relief effect,that is,the greater the pressure level of the respondents The less likely the medium pressure is to be relieved.(4)The pressure of the interviewees mainly comes from work,study,fast-paced life and health issues.The favorite decompression activities in urban parks are:exposure to nature,social interaction and walking.According to the results of data analysis,the Kanghe Park in Hefei City is evaluated in the design of restorative space environment and suggestions for transformation are given to promote the combination of landscape research and practice.
