Research On Landscape Planning And Design Of Chengdu Forest Health Base Based On Evidence-Based Design

In the forest environment,the ecological environment is optimized by human factors in order to achieve the effect of health and healing.The landscape type that makes the interaction between people and the environment have positive physical and mental effects on users is called health landscape.In the social background of sub-health problems becoming more and more serious,health landscape is an important guarantee to promote people’s physical and mental health and improve quality of life.On the other hand,the emergence of a large number of urban diseases causes people to be more inclined to carry out outdoor activities,and the forest has become the main spatial carrier of outdoor activities.Relevant studies at home and abroad show that the quality of forest environment plays a certain role in assisting people’s physiological and psychological rehabilitation,and evidence-based design as a methodology can provide theoretical guidance for it.Based on the above background,this paper,guided by evidence-based design methodology,discusses a more scientific and reasonable landscape planning and design model of Chengdu forest health care base.Aiming at this subject,this paper mainly discusses and studies it from three levels:The first part is the basis of the research,which mainly discusses the two basic concepts of forest health and evidence-based design.Firstly,forest health care and evidence-based design were sorted out and summarized from the historical evolution and research types,and the research background,purpose,significance,scope,content,domestic and foreign status,methods,key problems to be solved and the innovation of this topic were mainly expounded.Furthermore,the definition,origin,process,characteristics and advantages of evidence-based design,as well as the definition,supporting theory and key construction contents of forest health care are expounded.The relationship between evidence-based design and health landscape and the enlightenment of evidence-based design to health landscape are summarized.The second part is the empirical study.Firstly,it analyzes the typical cases of the established forest health bases at home and abroad to obtain the evidence of previous results.Secondly,field investigation was conducted on the landscape of Chengdu and the three surrounding forest health bases,including the landscape status,landscape space and landscape elements,to obtain field investigation evidence.Next,questionnaire survey was conducted on users from landscape space,landscape elements and health care activities to obtain evidence of users’ demand for forest health care base landscape.Based on the above empirical evidence and guided by evidence-based design,the landscape design cycle chain of evidence-based design for forest health care base was established,and the landscape planning and design mode of forest health care base was proposed,including design objectives,principles,space composition and design points.Based on the summary and extraction of the three evidences above,the landscape planning strategy of forest health base based on evidence-based design is proposed at last.The third part is the design practice.By introducing the concrete steps of evidence-based design and "evidence" support into the landscape planning and design of forest health care base,the feasibility of evidence-based design in the landscape planning and design of forest health care base is verified,and the evidence-based design scheme and key points of landscape planning of forest health care base are elaborated by practical practice.The value of this study lies in providing more scientific and reasonable "evidence"support for the landscape planning and design of forest health and rehabilitation base,establishing a clearer landscape planning and design process of forest health and rehabilitation base to a certain extent,and providing reference for related health and rehabilitation landscape design.
