摘　　要：IPCC于2019年8月7日通过了《气候变化与土地特别报告》决策者摘要,报告第3章评估了气候变化与荒漠化的关系,取得了一些新认识,包括全球旱地(dryland)和荒漠化的范围、荒漠化过程与影响因素、荒漠化的检测与归因、荒漠化对自然和社会经济系统的影响、荒漠化对气候变化的反馈、未来气候变化对荒漠化的影响与风险,应对荒漠化与适应和减缓气候变化的联系。在估计荒漠化变化、荒漠化变化检测与归因、荒漠化对自然和社会经济系统的影响、荒漠化对气候变化的反馈、应对荒漠化与适应和减缓气候变化联系方面还存在不足。这些评估结果对我国认识旱地和荒漠化范围的变化、影响荒漠化因素、荒漠化过程、荒漠化变化检测与归因,荒漠化对自然和社会经济系统的影响、荒漠化对气候变化的反馈、未来气候变化对荒漠化的影响与风险,以及防治荒漠化与适应和减缓气候变化方面等都有重要的启示。for policymakers(SPM) for the special report on climate change and land of the IPCC has been approved on August 7, 2019. The Chapter 3 of the report assesses the relationship between climate change and desertification, and some new insights include: drylands and desertification range, desertification process and influencing factors, desertification change detection and attribution, desertification impacts on natural and socio-economic systems, desertification response to climate change, future climate change impacts and risks to desertification, the linking of the response to desertification and adaptation and mitigation to climate change. There are still shortcomings in estimating desertification change, detection and attribution of desertification change, the impacts of desertification on natural and socio-economic systems, desertification response to climate change, the linking of addressing desertification and adaptation and mitigation to climate change. These understandings recognize China’s dryland and desertification range changes, desertification impacts factors and process, desertification change detection and attribution, the impacts of desertification on natural and socio-economic systems, desertification response to climate change, and future climate change impacts on desertification. There are important implications for risks and the links between combating desertification and adapting and mitigating climate change.
