2021年土地科学研究重点进展评述及2022年展望--土地工程与信息技术分报告

Progress Review on Land Science Research in 2021 and Prospects for 2022:The Sub-report on Land Engineering and Land Information Technology

研究目的:归纳分析2021年国内外土地工程与信息技术领域的研究进展,展望研究趋势。研究方法:文献分析法。研究结果:2021年,国内研究主要集中在国土综合整治和生态修复基础理论、土地开发强度与模式、土地整治模式与功能、复垦土壤质量及生态环境效应评价、生态修复关键区识别与分区模拟、土地利用与覆盖信息提取及基于不同视角的土地信息多尺度动态监测;国外研究重点关注城市化背景下土地开发模式与评估、土地整理区划、土地复垦质量、土地修复材料与方法、景观与可持续土地生态恢复耦合、土地利用与土地覆盖信息处理与动态监测技术。研究结论:2021年土地工程与信息技术在土地开发模式、农用地整治、土地复垦质量、国土空间生态修复、土地信息获取与处理技术等方面取得了一定进展。2022年及未来,将在生态文明建设及双碳战略的背景下,重点关注土地资源开发利用低碳转型、土地复垦理论与评价、国土空间生态保护修复理论与技术、乡村振兴背景下村庄综合整治以及土地信息监测的高精度与多尺度优化等问题。

The purposes of this paper are to summarize the research progress on land engineering and land information technology in 2021 and to give prospects in 2022.The method of literature review was employed.The results indicate that:in 2021,domestic research on land engineering and information technology mainly focused on the basic theory of comprehensive land consolidation and ecological restoration,intensity and mode of land development,mode and function of land consolidation,identification and zoning simulation of ecological restoration key areas,quality of reclaimed soil and evaluation of its ecological and environmental effects,land use/cover change(LUCC)information extraction and dynamic monitoring of land information based on multi-source remote sensing technology.International research focused on land development model and assessment in the context of urbanization,land consolidation zoning,land reclamation quality,land restoration materials and methods,the coupling of landscape and sustainable land restoration,LUCC information processing and dynamic monitoring technology.In conclusion,in 2021,land engineering and information technology made progress in land development model,agricultural land reclamation,land reclamation quality,ecological restoration of territorial space,and land information acquisition and processing technology,etc.In 2022,the research will focus on the low-carbon transformation of land resource development and utilization,the theory and evaluation of land reclamation,the theory and technology of ecological protection and restoration of territorial space,and the context of rural revitalization,and the comprehensive improvement of villages and the high-precision and multi-scale optimization of land information monitoring in the context of ecological civilization construction and dual-carbon strategy.
