Carrying out territorial ecological restoration is the requirement for ecological civilization and the construction of a beautiful China, and is an important nationally strategic task related to the ecological security and people's livelihood. This paper reviews the development context of the ecological environment governance centered on wilderness, rewilding, nature-based solutions, and ecological restoration in the past 100 years. We distinguish the relationship between concepts, clarify the basic research framework of international ecological restoration, and sort out the typical practice cases of ecological restoration abroad, and summarize the useful experience of the internationally ecological restoration. Based on analysis of the current situation of ecological and environmental problems in Guangdong Province and the international experience, this paper puts forward the general idea of scientific planning of land and space ecological restoration from five aspects:finding out the background, determining the goal, planning the pattern, arranging action, and implementing the guarantees, and puts forward nine special studies, research and development of ecological restoration technology, and multi-forms of organization and other strategies. The design idea and implementation paths of ecological restoration in Guangdong Province proposed in this paper will provide decision supports for identifying the root cause of ecological environment problems, achieving the targeted restoration and governance, and promoting the construction of ecological civilization.
