Ecological restoration of land space is an important measure to promote stability, pattern optimization, and function enhancement of the land space system. Its essence is to reconcile the relationship between people and nature and promote the harmonious coexistence of both sides. Under the background of the implementation of major projects of ecological restoration of land and space, constructing a scientific and reasonable planning strategy oriented to regional development and public needs is a research hotspot in the fields of geography and ecology. Man-land system coupling is the theoretical basis of land space ecological restoration planning. Therefore, this article studies and reviews the difference from traditional ecological restoration planning (TERP) to land space ecological restoration planning (LSERP) under the framework of man-land system coupling. In terms of planning, the TERP is guided by the restoration of ecological system problems, focusing on single-element discrete restoration; the LSERP is based on the "mountain, forest, field, lake and grassland" life community, highlighting the organic integration of ecological processes and space. TERP and LSERP have also undergone significant changes in planning goals, nature, objects, technological paths, scales and policy mechanisms. Taking the typical area with prominent man-land contradiction--the Guangdong-Hong Kong-Macao Greater Bay Area as a case, this article analyzes the prominent problems and situations faced by the Greater Bay Area from the perspective of man-land system theory. During the development of the Greater Bay Area, we are faced with problems and challenges, such as the separation of ecological protection elements from the urban development space, the opposition between protection and utilization, the numerous ecological needs, and the difficulty of implementation and control. Ecological problems are the outstanding shortcomings that restrict the high-quality development of the Greater Bay Area. In response to the above problems and needs, this article takes the promotion of human-land harmony in the study area as the general goal, from developing a harmonious ecological restoration strategy, protecting the ecological space as a whole, giving full play to the comprehensive functions of ecological elements, and strengthening mechanisms in terms of guarantees, we have constructed a land space ecological restoration planning strategy and ideas based on problem identification -strategic guidance - overall layout and zoning policy implementation, to enrich man-land system theory, planning theories and methods, as well as to develop land space ecology for other regions as a reference.
