Study On The Stratification Evaluation Ofguidance Quality Of Outdoor Public Spacein Commercial Complex

With the development of economy and internet,the huge impact of online commerce makes offline commerce gradually develop into an intensive mode,which integrates entertainment,leisure,food and shopping into a new business complex mode.In order to provide a good space experience,the design of outdoor public space of commercial complex becomes more and more important.However,a large number of commercial complexes have also brought a series of problems,including the lack of outdoor space orientation.It is necessary to study the design and research of the orientation of outdoor public space of commercial complex.The study of this research object is taken as the research object,and its oriented evaluation method is taken as the research object.Using the method of documentary investigation,this paper summarizes the relevant guiding basic theories,summarizes the guiding evaluation factors and their evaluation criteria,classifies the influencing factors hierarchically based on the study of planning and design of commercial complexes,and conducts field investigations on Tianjie,Wanxiangcheng,Longhu Xinyijie and Xinguang Tiandi in Chongqing.Questionnaires further clarify the actual situation and problems,and verify and supplement the impact factors of orientation.Hierarchical analysis is used to establish a hierarchical evaluation framework,and line of sight analysis and cohesion density are used to quantify the criteria and indicators.Experts and scholars in the field of landscape design and architecture are invited to grade the weight of the impact factors separately to further improve the construction of evaluation methods.Finally,the application is applied to the case of Tianjie outdoor public spacein Longhu era in Chongqing,and corresponding improvement suggestions are put forward at all levels to provide a clear reference for decision makers.In this study,the guiding factors are divided into macro-planning level,mesospatial design level and micro-detail design level,totaling 14 items.The macro-planning level mainly includes two aspects: spatial planning layout and transportation system,including dynamic line,continuity of dynamic line,efficiency of route and complexity of space.Medium level includes the recognition and memory of spatial nodes,the visibility of spatial nodes,the continuity of linear space and the orientation of space.The micro-level includes the recognition of the marking system,the visibility of the marking system,the regionality and classification of the marking system,the continuity of the number and distribution of the marking system,and each item has a detailed measurement index for evaluation reference.Finally,the practical application results show that the evaluation results are consistent with the survey and questionnaire survey,and have certain application value.
