Research On The Landscape Of Tianfu Furong Park In Chengdu City From The Perspective Of Health Preservation

Our country’s urbanization construction and development are in a period of rapid growth.The rapid increase in urban population has brought enormous economic benefits to cities,but it has also brought many negative impacts on the ecological environment,socio-economy,and human health.Especially with the country’s strong promotion of the new type of urbanization centered on the people,people’s demands for a better life are increasing day by day,and the role of urban parks is becoming increasingly important.In this tense and efficient urban environment,it is particularly urgent to create a comfortable and healthy recuperation landscape space.This study will select Chengdu’s typical urban park,the Chengdu Tianfu Furong Garden,starting from the comfort of local recuperation landscape,and evaluate the overall recuperation function of the park,with users as the main subject,considering the physiological and psychological stimulation of the landscape on the human body,selecting four typical recuperation landscape spaces as research objects,monitoring their environmental indicators,analyzing the response relationship between the environmental characteristics of different recuperation landscape spaces and physiological and psychological changes of the human body,judging the comfort of different recuperation landscape spaces,and using the Analytic Hierarchy Process(AHP)method to study and evaluate the recuperation landscape function of the park at the overall level,and identify its existing problems.The conclusion of this study is as follows:(1)According to on-site survey and monitoring data,indicators for the thermal environment,sound environment,air quality environment,and air cleanliness environment were obtained for different landscape spaces.The comprehensive comfort factors of different landscape spaces have certain differences.Based on the monitored environmental factors,the comprehensive evaluation score shows that the waterfront space has the best overall performance in terms of environmental comfort,followed by the flower space and lawn space.The square space has the worst performance,but all four landscape spaces are better than the control space.(2)Through an experiment on the perception of landscape space experience,it was proved that landscape space has a positive effect on human physiological and psychological responses.This is mainly reflected in the decrease of blood pressure and heart rate,the increase of blood oxygen concentration,the decrease of emotional disturbance value,the improvement of perception recovery and other indicators.In addition,the comprehensive comfort index and score of landscape space environment are correlated with human physiological and psychological indicators,and different landscape spaces also have different effects on human physiological and psychological indicators.(3)By evaluating the health and wellness functions of a park’s landscape through a questionnaire,7 criteria and 37 sub-factors were scored and valued.The results showed that plants scored the highest,while water scored the lowest.A satisfaction survey of the park was conducted using a Likert scale,and the results were correlated with the weighted values,showing a high degree of correlation,which demonstrated the representativeness of the evaluation results of the system.
