Strengthening the construction of standard systems for the ecological protection and rehabilitation of mountain-river-forest-farmland-lake-grass is the basic work of unified land space ecological protection and rehabilitation. More than 350 standards exist for the ecological protection and rehabilitation of mountain-river-forest-farmland-lake-grass in China, which are associated with problems such as inconsistent standard systems, cross-duplication, poor coordination, long duration of publication, and a lack of key standards. This study reviewed the relevant field standards, combining the practice of ecological protection and rehabilitation of mountain-river-forest-farmland-lake-grass in China. It is proposed that mines, water environments, forests, farmland, lakes, grasslands, wetlands, oceans, countryside, and cities are taken as study objects, focusing on ecological problems and project types. The functional requirements of ecological target control, investigation, monitoring, and evaluation, planning and design, engineering technology, ecological maintenance, and management, are studied to establish a unified standard system for the ecological protection and rehabilitation of mountain-river-forest-farmland-lake-grass, guiding the construction of ecological protection and rehabilitation projects of mountain-river-forest-farmland-lake-grass and the ecological restoration of land space in China.
