By reviewing the development history of concepts and contents on land consolidation at home and abroad, the basic connotation and work needs of land consolidation in the new era were summarized. By analyzing the wide application of remote sensing in land consolidation works, the development of remote sensing monitoring of land consolidation was sorted out, the related key technologies and its research status were summarized, and then the development trend of related technologies and applications of land consolidation remote sensing monitoring were given. The application of remote sensing technology in land consolidation works for many years was systematically expounded from two angles. These two angles were different types and project stages of land consolidation. The different types of land consolidation included land resource survey and protection, land reclamation and ecological restoration, agricultural land consolidation, development of unused farmingsuitable agricultural land, construction land consolidation and ecological land consolidation and so on. The different project stages of land consolidation included potential and risk measurement, engineering planning, construction supervision and acceptance evaluation and so on. Finally, the research difficulties and development direction in the future were put forward based on summarizing the technical advantages and limitations. The research result can provide scientific reference for the implementation of remote sensing monitoring of land consolidation.
