Study On The Restorative Environment Of Urban Greenway Space

In recent years,the city is in a stage of rapid development.Urban development and fast-paced life have led to a series of problems such as urban pollution,heat island effect and human diseases caused by fast-paced pressure.Problems such as mental fatigue,decreased attention,and health hazards caused by people’s daily life can be recovered through recreation in the natural environment.Greenway is an important natural environment place in the city,which has a great recovery effect on human physiological and psychological health.In this paper,urban greenways are taken as the research object to study the restorative effects of different types of urban greenways on the human body and explore the restorative environmental factors,so as to provide a theoretical basis and practical support for the restorative environmental design of urban greenways in the future.This paper conducts field research on Beilin Jiang’an River Greenway,Beilin Lujiatan Greenway,Nancheng Binjiang Road Greenway,and Nancheng Nanxun Avenue Greenway in Wenjiang District,Chengdu City.Through consulting relevant literature and referring to the space type division of urban parks,the greenway space is divided into three types of space: forest space,waterfront space,and lawn space.A questionnaire survey was conducted for the visitors to the four greenways,and the crowd characteristics were analyzed.The fixed-point measurements of the four greenways in summer from June to July and winter from November to December included three physical environment indicators: temperature,humidity and noise.Through data analysis and comparison,representative Lujiatan greenways in Beilin and Nanxun Avenue greenways in Nancheng were selected as the experimental greenways for this restorative environment study.In the experiment,30 volunteers,15 men and 15 women,were recruited and randomly divided into three groups.The physiological indicators(blood pressure and heart rate),psychological indicators(POMS mood state scale)and the restorative environmental factor evaluation form filled in by volunteers after recreation in the waterfront space,forest space and lawn space of Lujiatan Green Road in Beilin and Nanxun Avenue Green Road in Nancheng were recorded respectively.The experimental data were analyzed and sorted out,and SPSS software was used to analyze the mean value of the physiological data and psychological data measured in each space,Shapiro Wilk normal distribution test,paired sample T test and analyze the physiological and psychological recovery effect of volunteers in each space.Analyze the evaluation table of restorative environmental factors in each space,and explore the causal relationship between each restorative environmental factor in each space and human pressure release through mean value analysis,correlation analysis and linear regression analysis.Based on the analysis of the data obtained from the experiment,the paper explores the restorative landscape construction methods of waterfront space,understory space and lawn space of the greenway.Through empirical research and analysis,the following conclusions are drawn:(1)Through the measurement and analysis of physical environment,the temperature,humidity and noise index of the three types of space in four greenways in winter and summer found that the overall physical environment of the forest space and waterfront space was better than the lawn space.Women are slightly more than men in the greenway visitors,and the age stage is mainly young and middle-aged people.Walking is the most frequently selected way to visit the greenway.It is found in observation that waterfront space is the greenway space with the highest frequency of sightseeing.(2)The three spaces of Lujiatan greenway in Beilin and Nanxun greenway in Nancheng can effectively reduce the blood pressure and heart rate of most volunteers,which has a certain role in promoting the recovery of human health.Waterfront space has the best effect on human physiological health recovery,followed by forest space and lawn space.In the impact of human mental health recovery,waterfront space,forest space and lawn space have promoted the recovery of human mental health.The natural environment of the three spaces can effectively reduce the negative emotions of most people and enhance the positive emotions.The restorative environmental factor of waterfront space is mainly the beautiful and natural revetment,the restorative environmental factor of undergrowth space is mainly the richness of plant color,and the restorative environmental factor of lawn space is mainly the beauty of space form.According to the three different types of greenway space,the restorative environmental factors of the space,such as beautiful and natural revetment,rich plant color,and beautiful spatial form,are reasonably matched and optimized to optimize the restorative environment of the greenway.(3)According to the above research conclusions,the construction strategy of greenway space restorative landscape is proposed.In the waterfront space,the view of water landscape can be expanded,the rest facilities can be increased,and the beauty of waterfront revetment plants can be improved;In the understory space,it can ensure the richness of plant species,enhance the richness of plant color,beautify the road pavement,and reasonably plan the width of greenway;In the lawn space,it can enhance the sense of nature,improve the coverage and quality of the lawn,and enrich the level of plant landscape.
