摘　　要：通过优化土地利用实现增汇减排,是当前自然资源管理部门和学术研究领域在“碳中和”目标要求下所面临的新问题与挑战。本文系统梳理了土地利用碳源/汇作用机理、土地利用碳源/汇效应、国土空间碳监测以及低碳土地利用等重点领域的研究进展,总结了当前研究的不足和面临的新挑战。考虑“碳中和”目标和新时期发展要求,提出在未来要加强基于多源数据融合的高精度国土空间碳监测、基于多尺度融合的低碳土地利用技术和智能化土地利用碳收支核算平台建设等方面研究;建议将“双碳”目标和低碳理念贯穿国土空间规划编制和实施过程,开展三生空间用地低碳化建设以及将碳评价纳入具体用地管理过程等。该研究对土地利用助力碳中和科学研究以及实践应用具有一定的借鉴意义。Under the target of carbon neutrality,how to increase carbon sink and reduce carbon emissions through land use optimization is both a new opportunity and a challenge for the academic research and the natural resource management department.In this paper,we systematically summarized several main research progress,including the mechanism how land use causes carbon source/sink change,the influence of land-use change on carbon source/sink,the carbon monitoring in space,and the low-carbon land use.Then,we summarized the research shortages and the challenges in the future study.By considering both the carbon neutral target and the development requirements in a new era,this study proposed several future research areas that need to be strengthened:to monitor carbon emissions in high resolution by integrating multisource data,to develop the integrated low-carbon land use technology from multi-perspectives,and to explore the intelligent platform for quick calculation of land-use-change caused carbon source/sink,etc.This study also proposed some policies for governments,including making the dual carbon objective and low carbon concept a constraint requirement through the whole preparation and implementation process of land spatial planning,adding carbon evaluation to individual land use management process,and strengthening low-carbon land use for production-living-ecological lands according to their land use characters,etc.This research can provide references for carbon neutrality promotion from the aspect of land use,both for scientific research and practical applications.
