Progress Review on Land Science Research in 2019 and Prospects for 2020: The Sub-report on Land Engineering and Land Information Technology

The purpose of this paper is to summarize the research progress on land engineering and land information technology in 2019 and give prospect in 2020. The method of literature review was employed. The results indicate that: in 2019, the development direction on land engineering and land information technlolgy in domestic transformed to the land space consolidation and development with ecological priority, leading to the research on general land comprehensive consolidation, ecological restoration in land space and mining areas, and the extensive utilization in land information monitoring and visualization. The overseas studies are inclined to land consolidation and reallocation, the assessment system of land reclamation, environmental issues in land development, bioremediation technology, dynamic monitoring and assessment of land information. In conclusion, in 2019, land engineering and land information technology made progress mainly in the fields of land comprehensive consolidation, ecological environment restoration, land space development, land reclamation quality, land remediation methods, dynamic monitoring technology. In 2020, more attention could be given to the technology and standards of general land comprehensive consolidation and ecological environment restoration, further improvement in the subject system of land reclamation, innovation on remediation materials and technology for polluted land, and the pace acceleration of multi-dimension improvement in land information technology.
