2018年土地科学研究重点进展评述及2019年展望 ——土地工程与信息技术分报告

研究目的：归纳分析2018年国内外土地工程与信息技术领域的研究进展，展望2019年国内研究趋势。研究方法：文献法。研究结果：2018年国内研究重点主要集中在耕地后备资源开发、生态整治、村庄整理、充填复垦技术、植物与钝化剂修复、无人机摄影测量与遥感技术在土地信息采集中的广泛应用及3S技术尤其是合成孔径雷达干涉测量技术在土地动态监测中的广泛应用；国外研究侧重于降低开发密度、土地整理有限领域选择、土地复垦碳排放问题、联合修复技术、土地信息处理方法的革新及多源遥感技术在土地动态监测中的应用。研究结论：2018年土地工程与信息技术，随着生态文明体制的改革、乡村振兴战略的提出及3S技术的迅猛发展，在土地生态整治、土地复垦技术、土地修复方法、动态监测技术等方面有所发展。2019年，将继续推进土地生态建设、进一步提升复垦土壤质量、优化复垦技术、改进污染土地修复方法，发展土地信息技术，在以解决生态环境问题和坚决打好污染防治攻坚战的前提下，推动生态文明迈上新台阶。

Progress Review on Land Science Research in 2018 and Prospects for 2019: The Sub-report on Land Engineering and Information Technology

The purpose of this paper is to summarize the research progress on land engineering and information technology in 2018 and give prospect in 2019. The method of literature review was employed. The results indicate that: in 2018, the domestic studies mainly focused on the development in reserve resources of cultivated land, ecology renovation, land readjustment in rural residential area, filling technology, restoration of plants and deactivators, and the extensive utilization in land information collection with the technology of unmanned aerial vehicle photogrammetric and remote sensing, and land dynamic monitoring with interferometry technology of aperture radar, a special 3S technology. The overseas studies focused on reduction in development density, finite field choice to land consolidation, problem with carbon emission in land reclamation, combined remediation technology, innovation on land information treatment, and the utilization of multi-source remote sensing technology in land dynamic monitoring. In conclusion, in 2018, land engineering and information technology made great progress mainly in the fields of land ecological renovation, land reclamation technologies, land remediation methods, dynamic monitoring methods and other fields with the accelerating pace of institutional reform in ecological civilization, proposal to rural revitalization strategy and tremendous development in 3S technology. In 2019, more attention could be given to promotion of land ecological construction, further improvement in the quality of reclaimed soil, optimization to reclamation technology, innovation on remediation methods for polluted land and development of land information technology. In the context of solving the ecological environment problem and the problem of pollution control, the ecology civilization could be promoted to a new stage.
