Sustainable soil management renders multifaceted benefits to meeting the United Nations Sustainable Development Goals (FAO, 2018; Hou et al., 2020; Keesstra et al., 2016). Its implications for climate change mitigation has been drawing particular interest in recent years (FAO, 2017; Poulton et al., 2018). On the one hand, soil represents the largest carbon pool in the Earth's terrestrial system, accounting for nearly five times that of the atmospheric carbon pool (Jansson & Hofmockel, 2020; Le Quere et al., 2018); on the other hand, N₂O, CH₄ and CO₂ emissions from soils all represent significant fluxes that affect greenhouse gas balance in the atmosphere (Lal, 2019; Tian et al., 2019; Zhu et al., 2018). Soil micro-organisms play a critical role in the cycling of soil organic carbon (SOC), but we still lack sufficient scientific knowledge to build quantitative predictive models in the context of soil use and management (Cavicchioli et al., 2019; Jansson & Hofmockel, 2020). There is an urgent need to better understand how soil use and management affect climate change, due to both carbon sequestration and greenhouse gas emissions.

Climate change also has a significant effect on soil carbon balance (Davidson & Janssens, 2006). On a global scale, rising temperatures have resulted in the higher heterotrophic respiration of SOC and thus CO₂ emissions; however, this is partly due to increased plant growth and autotrophic fixation (Jansson & Hofmockel, 2020). Due to the complex feedback loops involved in these processes, the effect of climate change on the net flux of greenhouse gas emissions still remains unknown (Bradford et al., 2016; Davidson & Janssens, 2006). To better understand these interactive dynamics, it is imperative to have more field monitoring data and an in-depth examination of data from different sources.

Given the interest among soil scientists, as well as great potential societal impacts, our editorial team at the journal of Soil Use and Management is commissioning a virtual special issue (VSI) with the topic of ‘Soil and Climate Change Mitigation’ (https://onlinelibrary.wiley.com/doi/toc/10.1111/(ISSN)1475-2743.soil-and-climate-change-mitigation). So far we have collected 22 papers, covering topics including (a) soil and greenhouse gas (N₂O, CH₄, CO₂) emissions, (b) soil and carbon sequestration and (c) monitoring strategies. We intend to keep updating this VSI and continually collect high-quality research papers pertaining to climate change mitigation with sustainable soil management.

可持续的土壤管理为实现联合国可持续发展目标提供了多方面的好处（粮农组织，  2018年;侯等人，  2020年;基斯特拉等人，  2016年）。近年来，其对减缓气候变化的影响引起了人们的特别关注（FAO，  2017 ; Poulton et al。，  2018）。一方面，土壤是地球陆地系统中最大的碳库，几乎是大气碳库的五倍（Jansson＆Hofmockel，  2020 ; Le Quere et al。，  2018）; 另一方面，N ₂ O，CH ₄和CO ₂土壤中的所有排放均代表着影响大气温室气体平衡的重要通量（Lal，  2019 ; Tian等，  2019 ; Zhu等，  2018）。土壤微生物在土壤有机碳（SOC）的循环中起着至关重要的作用，但我们仍然缺乏足够的科学知识来在土壤使用和管理的背景下建立定量预测模型（Cavicchioli等人，  2019 ; Jansson和Hofmockel ，  2020年）。迫切需要更好地了解由于碳固存和温室气体排放而造成的土壤利用和管理如何影响气候变化。

气候变化对土壤碳平衡也有重要影响（Davidson＆Janssens，  2006）。在全球范围内，温度升高导致SOC的异养呼吸增多，从而导致CO ₂排放增加。然而，这部分归因于植物生长的增加和自养固定（Jansson＆Hofmockel，  2020年）。由于这些过程涉及复杂的反馈回路，因此气候变化对温室气体排放净通量的影响仍然未知（Bradford等，  2016； Davidson＆Janssens，  2006）。为了更好地理解这些互动动态，必须拥有更多的现场监视数据并深入检查来自不同来源的数据。

考虑到土壤科学家的兴趣以及巨大的潜在社会影响，我们在《土壤利用与管理》杂志上的编辑团队正在委托撰写虚拟专题（VSI），主题为“缓解土壤和气候变化”（https：/ /onlinelibrary.wiley.com/doi/toc/10.1111/(ISSN)1475-2743.soil-and-climate-change-mitigation）。到目前为止，我们已经收集了22篇论文，涉及的主题包括（a）土壤和温室气体（N ₂ O，CH ₄，CO ₂）排放，（b）土壤和碳固存和（c）监测策略。我们打算不断更新此VSI，并继续收集与通过可持续土壤管理减轻气候变化有关的高质量研究论文。
