Abstract: Cities develop rapidly as a result of the expansion of physical space and population density. When the renewal of squares is out of sync with urban development, the safety factor of the pedestrian space will be reduced, and the probability of safety accidents will increase. Public landscape, a component of the square pedestrian space, affects safety in this space. This paper cites Chongqing Three Gorges Square as the research target. By applying the analytic hierarchy process-fuzzy comprehensive evaluation method, it carries out landscape safety evaluation in the perspectives of greening, roads, waterscape design and landscape pieces. It goes on to define the priority of landscape safety design, finds out the hidden danger, and provides proposals on the design of public landscape safety in the pedestrian space of city squares, through organic combination of qualitative analysis and quantitative calculation for safety assessment
