Study On Health Oriented Landscape Evaluation And Optimization Design Of Greenway Of Nanjing Ming City Wall

Urban green space carrying health activities is an important medium to achieve the goal of urban health.The health demand under the change of the times also promotes the development of urban green space.Urban waterfront greenway can not only promote the healthy development of urban ecology and guide the construction of urban health,but also provide supporting space for public health behavior.It plays an important role in promoting health in many aspects.It is a good choice to build an urban green space with health-oriented function.However,there are many deficiencies in the current situation of urban waterfront greenways,which can not meet people’s health needs,let alone attract more users to participate in health activities.Therefore,it is necessary to optimize the design of urban waterfront greenways in combination with the concept of health orientation,so as to give full play to the health benefits of the environment.Firstly,through literature review and field research,this paper summarizes the health-oriented environmental needs,combined with the constituent elements of urban waterfront greenways,summarizes the healthy environmental characteristics of urban waterfront greenways at the four levels of "natural and ecological,safe and unobstructed,comfortable and pleasant,energetic and healthy",as well as the health benefit elements of ecology,applicability,functionality,comfort and interest;Then,through literature review and case analysis,this paper summarizes the health-oriented urban waterfront greenway design principles,and puts forward optimization design strategies from four aspects: protecting the natural ecological basement,creating a safe and unobstructed slow traffic,creating a comfortable and pleasant landscape environment,and creating a energetic and healthy functional space.Based on the above research,the health quality evaluation model is constructed through analytic hierarchy process.Taking the greenway of Nanjing Ming City Wall as an example,Yueya Lake Park,Wudingmen Park and Xiao Tao Yuan with typical characteristics are selected as the research objects.Questionnaires and on-site interviews are conducted to obtain the health quality score,summarize the current problems and put forward the corresponding optimization strategies,The universal conclusion is applied to the optimization design case of urban waterfront greenway with individual particularityFinally,it summarizes the health-oriented urban waterfront greenway optimization design strategy,points out the inadequacies of the research,and puts forward its own outlook for the practical development of the environment to promote people’s health.
