Research On Public Space Design Strategy Of Large General Hospital Of Hospital Street Model Based On Spatial Quality Evaluation

As an important design mode in the construction of modern general hospital,hospital street model has developed rapidly in the past 30 years in our country.At the same time,the change of medical concept and user needs has put forward higher requirements for the public space of hospitals.There are still contradictions in the real use of hospital public space in decision-making points,transportation systems,guidance systems and functional sequence.It is necessary to further optimize the existing space.It is particularly important to systematically study the public space of large general hospitals under the hospital street mode under the background of hospital construction.With the help of post-use assessment technology of built environment,this paper innovatively applies environmental quality assessment and cognitive map to the spatial quality assessment of large general hospitals to fill the theoretical gap in this field.The research adopts the "structure-humanities" evaluation method to study the physical environment of the building quantitatively and qualitatively,inspects the psychological needs and behavioral tendencies of the users of public space,tries to find out the existing problems to weigh the design gains and losses,and puts forward the optimization strategy of the design of public space of the hospital based on the project practice in which the author participates.According to the research progress and the structure of the text,this paper is divided into three parts.The first part is the construction of the research framework.It mainly elaborates the origin and background of the research,defines the concept and scope of the research object,then clarifies the content,significance and strategy of the research,and gives corresponding explanations for the innovation of the research,and puts forward the research framework according to the strategy.On the other hand,through exploratory research on the evaluation object and subject,typical samples are screened out,and the scope of public space is further defined to provide a basis for follow-up research.The second part is the evaluation part of this article,focusing on the cognitive research of hospital public space.By using environmental quality assessment and cognitive map assessment,the explicit and implicit needs of users for public space in hospitals are investigated.With the environmental quality of public space and the recognition of public space in the process of seeking medical treatment as the purport,the corresponding evaluation factor model and some key points in the design of public space in hospitals are obtained.The third part is the abstraction of conclusions and the transformation of achievements.According to the conclusions of evaluation and cognition,the research results are implemented into the level of architectural design concept,and the results of design guidelines are fed back to practical engineering cases,so as to concretize the research conclusions,which has universal practical guiding significance.
