Against the backdrop of smart city development

this paper conducts research on the current problems existing in waterfront public spaces

such as degradation of ecological quality

insufficient service efficiency

and lack of humanistic experience. By systematically sorting out the core concepts and technical frameworks of smart cities

it establishes a strategic system for waterfront space environmental optimization covering three dimensions: intelligent monitoring and regulation of the physical environment

smart management and services for space use

and enhanced public participation and interaction. Combined with typical waterfront cases

strategy application and feasibility verification are carried out. The results show that this system can effectively improve the ecological resilience

management efficiency and humanistic care level of waterfront spaces

providing practical optimization paths and decision support for the renewal and quality improvement of waterfront spaces under the concept of smart cities.
