A Study On Waterscape Design Strategies Of Urban Public Space Based On Safety

Waterscape is one of the most active forms in urban public space,which has the functions of sightseeing and recreation,creating space atmosphere,transforming microclimate and so on.Waterscape space often has potential safety hazards,such as non-skid pavement,sharp corners,high water level,aging of power equipment,resulting in slip,collision,abrasion,drowning,electric shock and other accidents,affecting the personal safety of the public.This study takes the security of urban public space waterscape as the entry point and takes Shanghai as the object to conduct field investigation and study on 14 waterscape spaces,including four major types of waterscape space,and they’re riverside space,park green space,street green space,and residential green space waterscape.Through on-the-spot investigation of various types of waterscape,the influence relations was probed into,which is between the elements of the three levels of waterscape design and safety.Then,the fishbone diagram analysis method was used to clarify the hidden safety hazards and their causes in the safety of urban public space waterscapes,and an analytic hierarchy model evaluation system was constructed.Taking the safety-based urban public space waterscape design strategy research survey as the target layer,the criterion layer,the index layer and the sub-index layer are set up in sequence for expert scoring.According to the scoring results of 30 experts,the weight ranking of each impact factor at the criterion level is obtained: safety management system design(0.5565),landscape and structural design(0.3425),waterscape surrounding environment design(0.1010),and a waterscape safety design strategy based on the three-level weight ranking is proposed.On the basis of theoretical research,field investigation and typical case analysis,this study constructs a scientific and comprehensive impact system of waterscape security in urban public space,the safety design strategies of waterscape public space are put forward with strong implementation and operability,and the application of safety theory in landscape planning and design is expanded.The research results have strong theoretical value and practical significance for the safety promotion of urban public space,it provides the theoretical basis and practical reference for the evaluation and optimization of the existing waterscape space security and the design of the future waterscape space security.
