As urban ecological civilization advances rapidly, equity issues in urban landscape planning—a public welfare endeavor—have become increasingly prominent. This study constructs a multidimensional framework for landscape design activism by integrating public participation, urban equity, and spatial innovation, and evaluates landscape design’s spatial accessibility and urban equity. The evaluation of social equity in urban parks employs three metrics: the Gini coefficient, Lorenz curve, and locational entropy. Spatial accessibility is analyzed using spatial syntax. Case study findings reveal that green space service levels are highest in medium-density areas within Points of Interest (POI), followed by low-density zones. High-density and extremely high-density areas exhibit lower service levels, with overlapping service ranges and concurrent service blind spots. The study area exhibits significant inequity in landscape green space service distribution and spatial accessibility, with a Gini coefficient as high as 0.85.
