Abstract

Abstract: Based on the theories of geography and landscape ecology, land ecological restoration is an important strategy to promote ecological civilization and build a beautiful China. Land ecological restoration in China has the characteristics of multi-disciplinary theoretical system, diverse work mode, integration of technology and methods, and diversified practice and exploration. The overall effectiveness of the work coexists with arduous tasks. Based on the new challenges in land ecological restoration, we summarized the overall framework and technical path of land ecological restoration, the working mechanism and mode of regional land ecological restoration, the content system and technical standards of land ecological restoration. In the new stage, the top-level design of land ecological restoration in China should focus on the work system, business boundary and institutional system, identify the responsibility boundary of different business processes, and realize the closed management of the whole work chain from the perspective of theory, system, engineering and technology. Rural settlement area, urban built-up area, industrial and mining gathering area, ecological function area and blue ocean area are the five major elements of regional scale land space, which correspond to five different ecological restoration modes, namely, comprehensive land improvement, urban renewal and double repair, mine geological environment restoration, mountain-river-forest-farmland-lake-grassland restoration, and blue bay restoration. It is necessary to comprehensively use the thinking of “Three Integrations” (information, technology, and process) to build a set of regional land ecological restoration work mode covering the integration of investigation, monitoring and evaluation, land space planning, project implementation, project acceptance and ecosystem monitoring and evaluation.

Key words: land ecological restoration, concept, mode
