Aff ected by extreme weather, soil erosion on the slopes of some historical gardens in cities has become increasingly severe in recent years, posing a signifi cant threat to the ecological environment, landscape style, and the safety of ancient buildings and cultural relics. In this context, taking the ecological restoration of the “Yichi Yunzai” slope of Wanshou Mountain in the Summer Palace as an example, based on the “Patch Corridor Matrix” model of landscape ecology, the spatial distribution characteristics of soil erosion are coupled with the landscape ecological pattern from the multidimensional perspectives of ecological restoration, functional synergy, and cultural continuity. The practice follows the technical path of “matrix stabilization corridor diversion patch restoration”. By constructing a “three-dimensional linkage” restoration system, namely ecological foundation restoration, landscape space improvement, and historical scene reconstruction, the dual goals of protecting the integrity of historical landscapes and enhancing the resilience of ecosystems can be achieved, promoting the integration and innovation of landscape ecology theory and traditional garden soil and water conservation technology. Research and explore an ecological restoration approach suitable for high-human-disturbance historical gardens, develop replicable solutions, and provide technical references for similar soil and water conservation work.
