Abstract: Landscape management is an important component of the management system of protected areas. In this paper, we take landscape management of protected areas as a special category of space management, and introduce Lefebvre’s “three-dimensional space theory”. Citing the local landscape of Changgou Spring National Wetland Park as an example, the study explores the influence mechanism of the interrelation between landscape management of protected areas and the landscape space, and puts forward four practical models of design intervention in landscape management. With its own advantages, design can adjust the contradictions and deviations of policy formulation, planning and design, system management, monitoring and evaluation.
