摘要:

总结了IPCC《气候变化与土地特别报告》中有关陆气相互作用、粮食系统与粮食安全、土地退化和荒漠化、可持续土地管理等的主要结论,分析了报告中争议较大的粮食系统温室气体排放、生物质能源、土地温室气体通量等问题。我国在粮食系统全生命周期温室气体排放量估算、基于遥感测量和地面测量的大气浓度等数据反演温室气体排放量等方面需要深入研究。同时,我国要继续加强可持续土地管理,提高相应的技术措施和能力建设。

关键词: 气候变化, 荒漠化, 土地退化, 粮食安全, 可持续土地管理

Abstract:

In this study, the key conclusions of the IPCC special report on climate change and land (SRCCL) on land-climate interactions, food system and food security, land degradation and desertification, and sustainable land management were summed up. And the most controversial scientific issues in the report, such as greenhouse gas emissions from the food system, bio-energy and the estimate of carbon dioxide emissions and removals for the land sector were analyzed. Some scientific issues, such as the estimation of greenhouse gas emissions in the overall life cycle of food system, and the retrieval of greenhouse gas emissions based on remote sensing and ground-based measurement of atmospheric concentration and other data, need to be further studied in China. In the meanwhile, China should continue to implement sustainable land management, and improve corresponding technical measures and capacity-building.

Key words: Climate change, Desertification, Land degradation, Food security, Sustainable land management
