| In recent years,there have been frequent public health incidents,which have had a huge impact on human health and attracted unprecedented attention to health issues.As an urban green space type close to residential areas,urban community parks have become an important entry point for active intervention in human health through the environment.A good community park environment can promote the healthy lifestyle of residents,so based on the needs of users,reasonable planning and design is carried out to create a comfortable,healthy,safe and ecological community park environment,so as to improve the outdoor activity experience of urban residents and promote people’s healthy lifestyle,which has certain research value.Based on the perspective of public health,the landscape of Zhengzhou Community Park is studied from the perspective of users’ experience and behavioral needs:(1)The concept and type of public green space on health promotion mechanism are basically studied.From the perspective of users,this paper is carried out from the five aspects of community park environment,user exercise activities,park infrastructure,traffic conditions in the park,and users’ psychological feelings,and 24 element indicators are extracted from these five aspects to construct the landscape evaluation system of urban community parks.(2)The weight of each evaluation index was obtained by using the analytic hierarchy method,and the weights of the criterion layer were healthy environment(0.4805),> health facilities(0.2142),>healthy transportation(0.1455),> health perception(0.0616)> healthy exercise(0.0982),and the index layer had a large weight in its criterion layer: park ornamentation(0.1750),plant configuration rationality(0.1278),barrier-free facilities(0.0711),etc.Three representative community parks in Zhengzhou,namely Jingxiu Park,Green Park and Navigation Park,were selected as the main research objects,and the data of various landscape elements were collected,and the reliability and validity of the collected questionnaire results were analyzed by SPSS25.0.The fuzzy comprehensive evaluation method was used to evaluate three representative community parks in Zhengzhou,and the order of landscape experience was as follows: Jingxiu Park(3.132),> Green Park(3.003)> Navigation Park(3.001).(3)Based on the evaluation results of the research subjects,the three community parks were again investigated in detail,the specific problems of each park were analyzed,and the common problems of the three parks were summarized.Based on the research results of the above problems,from the five aspects of environment,activities,facilities,transportation and perception,the landscape optimization strategy of community parks is proposed: using plant landscape to construct a green healing environment;Promote users’ healthy exercise by optimizing site zoning,enriching fitness equipment,equipping rehabilitation equipment,and designing smart runways;Increase the temperature of the landscape and promote the healthy feeling of users;Set up flexible spaces to enhance the resilience of the park;Optimize basic service facilities to facilitate healthy leisure activities.Finally,the optimization strategy is applied to the landscape design practice in specific projects and plays a role in application demonstration.This paper innovatively constructs the community park landscape evaluation system from the perspective of public health,quantitatively evaluates the landscape status through analytic hierarchy method,fuzzy comprehensive evaluation method and factor analysis method,conducts qualitative research on the landscape status through field investigation and observation,puts forward the landscape design strategy of urban community park on the basis of the combination of qualitative and quantitative evaluation results,and conducts landscape design practice on the design strategy through specific projects,which provides a certain reference for the research of urban community park landscape design. |
