Quantitative studies on the national-scale effects of extreme climatic events on soil organic carbon (SOC) remain scarce, thus limiting our understanding of SOC dynamics. This study utilized 4515 publicly available soil samples to quantify the impacts of 19 extreme climatic indices (ECIs) on ΔSOC reservoirs in China through a hybrid space-for-time and meta-analysis approach. Overall, 16/19 ECIs were negatively correlated with ΔSOC, with the minimum temperature of the coldest night (TNn) showing the strongest negative correlation. Notably, topographic factors played a pivotal role in the modeling process, contributing an average of 25 %, followed by ECIs. Under the influence of the ECIs, SOC exhibited spatial variation. Extreme heat resulted in the greatest SOC losses in cold regions, such as North China, with average reductions of > 5 %, whereas its impact was weaker in South China, with SOC losses of ∼3 %. Extreme cold and wet indices promoted SOC accumulation in the Northeast China, with increases of ∼3 %, but showed a weaker response in the humid region, where the SOC increased by only 1 %. At the national scale, the impacts of extreme climatic events on SOC in the 0–20 cm ranged from −2.36 Pg to 2.34 Pg. Different ecosystems responded variably, with forest and grassland ecosystems being more sensitive to ECIs, potentially due to higher organic matter inputs and greater ecosystem complexity. In contrast, bare land exhibited weaker responses due to limited vegetation cover and organic inputs. These findings provide valuable insights into SOC dynamics at national scale during extreme climatic events.

极端气候事件对土壤有机碳（SOC）影响的定量研究仍然很少，因此限制了我们对土壤有机碳动态的认识。本研究利用4515个公开土壤样本，采用时空混合和元分析的方法，量化了19个极端气候指数（ECIs）对中国ΔSOC水库的影响。总体而言，16/19 eci与ΔSOC呈负相关，其中最冷夜最低温度（TNn）负相关最强。值得注意的是，地形因素在建模过程中发挥了关键作用，平均贡献了25%，其次是eci。在eci的影响下，土壤有机碳呈现空间差异。极端高温导致中国北方等寒冷地区的有机碳损失最大，平均减少5%，而中国南方的影响较弱，有机碳损失约为3%。极端寒冷和潮湿指数促进了东北地区有机碳的积累，增加了约3%，但在潮湿地区表现出较弱的响应，其有机碳仅增加了1%。在全国范围内，极端气候事件对0 ~ 20 cm土壤有机碳的影响范围为- 2.36 ~ 2.34 Pg。不同生态系统对eci的响应差异较大，森林和草地生态系统对eci更为敏感，这可能是由于更高的有机质投入和更大的生态系统复杂性。相比之下，由于植被覆盖和有机投入有限，裸地表现出较弱的响应。这些发现为研究极端气候事件期间全国范围内的有机碳动态提供了有价值的见解。

Safe and just operating spaces (SJOS) are influenced by complex cross-scale interactions and cascading effects spanning global, regional, and local landscape scales. However, existing SJOS research has often focused on single-scale assessments, overlooking the impacts of multiscale interactions and within-region heterogeneity on urban SJOS. To address this gap, we developed a cross-scale framework for assessing urban SJOS, explicitly incorporating top-down influences from upper-level constraints and bottom-up effects from lower-level heterogeneity. This approach was applied to China’s five major metropolises to examine the states and cross-scale dynamics influencing urban SJOS between 1990 and 2020. Our findings reveal that the SJOS of China’s metropolises were primarily influenced by factors at national and local landscape scales, with weaker influences from the global and continental scales. A persistent trade-off between social justice and environmental safety was identified across spatiotemporal scales. For instance, Chongqing in southwestern China lagged behind the eastern four metropolises in social performance but exhibited stronger environmental safety due to its extensive natural landscapes, which mitigated the anthropogenic impacts of urban centers. Regional issues, such as the overshoot of PM_2.5 and ecological footprints (EF), were primarily driven by the bottom-up accumulation of localized pressures, while the overshoot of CO₂ was attributed to national policy constraints and the universal exceedance of safe thresholds across scales. Addressing urban sustainability requires avoiding adverse cascading effects from other levels by emphasizing landscape heterogeneity within metropolises and fostering coordinated collaboration across scales, particularly at the regional landscape and national levels.

安全与公正的操作空间（SJOS）受到复杂的跨尺度相互作用和级联效应的影响，这些效应跨越全球、区域和地方景观尺度。然而，现有的城市sjo研究往往侧重于单尺度评估，忽视了多尺度相互作用和区域内异质性对城市sjo的影响。为了解决这一差距，我们开发了一个评估城市sjo的跨尺度框架，明确地结合了上层约束的自上而下影响和下层异质性的自下而上影响。以1990 - 2020年中国五大城市为例，研究了影响城市sjo的状态和跨尺度动态。研究结果表明，中国大都市的sjo主要受国家和地方景观尺度的影响，全球和大陆尺度的影响较弱。社会公正与环境安全之间的持续权衡跨越时空尺度。例如，中国西南部的重庆在社会绩效方面落后于东部四大大都市，但由于其广泛的自然景观，减轻了城市中心的人为影响，因此表现出更强的环境安全性。区域问题，如PM2.5和生态足迹（EF）的超调，主要是由局部压力的自下而上积累驱动的，而CO 2的超调则归因于国家政策约束和跨尺度的普遍超过安全阈值。解决城市可持续性问题需要通过强调大都市内部景观的异质性和促进跨尺度（特别是区域景观和国家层面）的协调合作，避免来自其他层面的负面级联效应。

The Sustainable Development Goals (SDGs) represent a solemn commitment by United Nations member states, but achieving them faces numerous challenges, particularly armed conflicts. Here, we analyzed the impact of armed conflict on SDG progress and its driving mechanism through causal inference methods and machine learning technique. The results show that between 2000 and 2021, armed conflicts slowed overall SDG progress by 3.43 %, equivalent to a setback of 18 years. The Middle East was the most affected region, with a 6.10 % slowdown in progress. The impact of different types of conflict varies across specific goals: interstate conflicts primarily affect SDG 5 (Gender Equality) and SDG 7 (Affordable and Clean Energy), while intrastate conflicts have a larger impact on SDG 4 (Quality Education) and SDG 9 (Industry, Innovation and Infrastructure). Additionally, SDG 15 (Life on Land) is severely affected by both types of conflict, with long-term consequences. As armed conflicts increase, the development progress would regress rapidly in a non-linear manner. To achieve the SDGs by 2030, it is crucial not only to prevent conflicts but also to proactively address and mitigate their impacts on development.

可持续发展目标是联合国成员国的庄严承诺，但实现可持续发展目标面临诸多挑战，特别是武装冲突。本文通过因果推理方法和机器学习技术，分析了武装冲突对可持续发展目标进展的影响及其驱动机制。结果显示，2000年至2021年期间，武装冲突使可持续发展目标的总体进展减缓了3.43%，相当于倒退了18年。中东是受影响最严重的地区，其进展速度放缓6.10%。不同类型冲突的影响因具体目标而异：国家间冲突主要影响可持续发展目标5（性别平等）和可持续发展目标7（负担得起的清洁能源），而国内冲突对可持续发展目标4（优质教育）和可持续发展目标9（工业、创新和基础设施）的影响更大。此外，可持续发展目标15（陆地生命）受到这两种冲突的严重影响，并产生长期后果。随着武装冲突的增加，发展进展将以非线性方式迅速倒退。要在2030年前实现可持续发展目标，不仅要预防冲突，而且要积极应对和减轻冲突对发展的影响。

High-altitude peatlands (HAPs; defined as > 1,500 m) provide important ecosystem services including soil carbon (C) storage. However, temperatures in high-altitude regions have been rising rapidly in recent decades, while HAPs are increasingly affected by human activities such as intensive drainage and grazing. Collectively, climate change and land management may strongly affect the HAP C cycle. Here, we synthesise current global progress on the HAP C cycle, focussing on the impacts of climate change and land management. Warming increased both ecosystem respiration (ER) and methane (CH₄) emissions (26 %–86 %), while impacts on net ecosystem exchange (NEE) of CO₂ were still unclear. However, short-term drought decreased ER and CH₄ emissions (7 %–96 %), along with NEE (12 %–52 %). Snow, permafrost, and glacier decline may also impact the C cycle in HAPs, although a limited number of studies have been conducted. Grazing and vegetation degradation impacts on HAP C cycling were related to grazing and degradation intensity, while generally decreasing soil organic C stocks (3 %–51 %). Moving from shallower to deeper WTLs stimulated ER (9 %–812 %), while reducing CH₄ emissions (13 %–100 %), with variable effects on NEE (-53 %–700 %). Restoration by rewetting began to reverse the trend of drainage. We highlight several knowledge gaps, including limited understanding of climate change and land-management effects on gross primary productivity and dissolved organic carbon, while there is still limited knowledge of regional differences in HAP C cycling. Future research should focus on the interaction of land-use and climate change in HAPs, including HAP restoration, which may help future conservation of these valuable ecosystems.

高海拔泥炭地（HAPs；定义为1500米）提供重要的生态系统服务，包括土壤碳(C)储存。然而，近几十年来，高海拔地区的气温一直在迅速上升，而HAPs越来越多地受到人类活动（如集约排水和放牧）的影响。总的来说，气候变化和土地管理可能强烈影响HAP - C循环。在这里，我们综合了目前全球在HAP - C循环方面的进展，重点关注气候变化和土地管理的影响。变暖增加了生态系统呼吸（ER）和甲烷（CH4）排放（26% ~ 86%），而对二氧化碳净生态系统交换（NEE）的影响尚不清楚。然而，短期干旱减少了ER和CH4的排放（7% - 96%），以及NEE（12% - 52%）。尽管开展的研究数量有限，但积雪、永久冻土和冰川的减少也可能影响HAPs中的C循环。放牧和植被退化对有机碳循环的影响与放牧和退化强度有关，而土壤有机碳储量普遍减少（3% ~ 51%）。从较浅的水体向较深的水体移动可刺激ER(9% - 812%)，同时减少CH4排放（13% - 100%），对NEE有不同的影响（- 53% - 700%）。复湿恢复开始逆转排水趋势。我们强调了一些知识空白，包括对气候变化和土地管理对总初级生产力和溶解有机碳的影响的了解有限，而对HAP - C循环的区域差异的了解仍然有限。未来的研究重点应放在旱地生态系统土地利用与气候变化的相互作用上，包括旱地生态系统的恢复，这可能有助于这些宝贵生态系统的未来保护。

The land, water, energy use, and greenhouse gas (GHG) emissions involved in agricultural production are intrinsically linked. However, quantitative characterization and scenario simulations of these elements’ inherent interrelationships remain scarce. We developed a land–water–energy–GHG (LWEG) nexus framework for the North China Plain (NCP). The framework identifies the mutual feedback in the life cycle of agricultural production among the four factors. We applied the framework to assess the agricultural GHG mitigation potential for winter wheat, summer maize, and rice in NCP municipalities. The results showed that cropping structure optimization reduced GHG emissions by 1.96 Mt CO₂e. Controlling indirect energy consumption in upstream processes of crop production and reducing on-site energy use reduced the volume and intensity per unit area of agricultural GHG emissions. Because of the synergies between land, water, and energy, nexus management, which combines multiple measures of groundwater management, fertilizer, and energy control, has substantial GHG mitigation potential. The nexus management scenario produced a total GHG of 159.51 Mt CO₂e, a decrease of 15.38 % from the baseline scenario. This study quantifies the LWEG nexus within agricultural production processes and identifies agricultural management practices that integrate water, energy conservation, and emissions mitigation contributing to the Sustainable Development Goals.

农业生产中涉及的土地、水、能源使用和温室气体（GHG）排放具有内在联系。然而，这些元素内在相互关系的定量表征和情景模拟仍然很少。建立了华北平原陆地-水-能源-温室气体（LWEG）联系框架。该框架确定了这四个要素在农业生产生命周期中的相互反馈关系。我们应用该框架评估了新农村地区冬小麦、夏玉米和水稻的农业温室气体减排潜力。结果表明，优化种植结构可减少196 Mt CO2e的温室气体排放。控制作物生产上游过程的间接能源消耗，减少现场能源使用，降低了单位面积农业温室气体排放量和强度。由于土地、水和能源之间的协同作用，结合地下水管理、肥料和能源控制等多种措施的联结管理具有巨大的温室气体缓解潜力。nexus管理情景产生的温室气体总量为15951 Mt CO2e，比基线情景减少15.38%。本研究量化了农业生产过程中的LWEG关系，并确定了将水、节能和减排结合起来的农业管理实践，这些实践有助于实现可持续发展目标。

Antibiotic resistance genes (ARGs) are increasingly recognized as a global public health threat, with glaciers acting as reservoirs for ARGs transported via atmospheric pathways. Warming climate accelerates glacier melting, releasing ARGs into downstream environments, posing ecological health and sustainable aquatic ecosystem development challenges. However, the distribution profiles of ARGs and their risks in glaciers from the polar region remain unclear. This study used 294 metagenomic sequences to investigate the distribution and risks of ARGs in glaciers across the Qinghai-Xizang Plateau, Antarctica, and the Arctic regions and compared them with adjacent and anthropogenically impacted environments. Among the three glacier regions studied, the Qinghai-Xizang Plateau exhibited the highest abundance of ARGs, whereas Antarctica displayed the lowest. ARG abundance in adjacent environments was comparable to that in the glaciers of the Qinghai-Xizang Plateau, but in the anthropogenically impacted environment, it was significantly higher than in glaciers. A shared resistome was identified in glaciers, dominated by bacitracin, multidrug, and macrolide-lincosamide-streptogramin (MLS) resistance genes. The bacA gene, which is related to bacitracin resistance, was the most common subtype, indicating that it is naturally present in microbial communities of glaciers. Risk assessments showed that 74.1 %–78.9 % of ARGs were low-risk in the Qinghai-Xizang Plateau and polar glaciers, indicating minimal human influence. However, 7.3 %–8.0 % were classified as high-risk, posing potential threats through horizontal gene transfer (HGT) and the spread of multidrug-resistant pathogens. These findings highlight the need to monitor ARGs in glacier environments, as climate change accelerates glacier melting and subsequent release of ARGs into downstream ecosystems.

抗生素耐药基因（ARGs）日益被认为是一种全球公共卫生威胁，冰川是ARGs通过大气途径运输的储藏库。气候变暖加速冰川融化，向下游环境释放ARGs，对生态健康和水生生态系统可持续发展构成挑战。然而，ARGs的分布概况及其在极地冰川中的风险仍不清楚。本研究利用294个宏基因组序列调查了青藏高原、南极和北极地区冰川ARGs的分布和风险，并将其与邻近环境和受人为影响的环境进行了比较。在研究的3个冰川区中，青藏高原ARGs丰度最高，南极洲最少。邻近环境中ARG丰度与青藏高原冰川相当，但在人为影响环境中，ARG丰度显著高于冰川。在冰川中发现了一个共享的抵抗组，主要是杆菌肽、多药和大环内酯-林科胺-链状gramin （MLS）耐药基因。与杆菌素耐药性有关的bacA基因是最常见的亚型，这表明它自然存在于冰川的微生物群落中。风险评估显示，青藏高原和极地冰川地区74.1% ~ 78.9%的ARGs为低风险，表明人类影响最小。然而，7.3% - 8.0%被列为高风险，通过水平基因转移（HGT）和多重耐药病原体的传播构成潜在威胁。这些发现强调了监测冰川环境中ARGs的必要性，因为气候变化加速了冰川融化，随后ARGs释放到下游生态系统中。

This study used 294 metagenomic sequences to investigate the distribution and risks of ARGs in glaciers across the Qinghai-Xizang Plateau, Antarctica, and the Arctic regions and compared them with adjacent and anthropogenically impacted environments. Among the three glacier regions studied, the Qinghai-Xizang Plateau exhibited the highest abundance of ARGs, whereas Antarctica displayed the lowest. ARG abundance in adjacent environments was comparable to that in the glaciers of the Qinghai-Xizang Plateau, but in the anthropogenically impacted environment, it was significantly higher than in glaciers.

The inequality of socio-economic resources has threatened individual well-being and urban sustainability. However, the inequality in different resource allocation scenarios is still unclear, and the accessibility distance to resources has not been considered. We developed a large-scale, long-term, and multi-perspective quantitative evaluation framework of inequality in the dividing-resource and sharing-resource scenarios over the past 31 years (1992–2022) within 15-minute cities. This framework is informed by patterns of urban development and the spatial distribution of resources and population. The results from 334 Chinese cities demonstrate the differences in inequality between developed and developing cities. When individuals share resources within 15-minute accessibility distance, inequality is lower in developed cities relative to developing cities due to more spatially balanced resources, with a decreasing trend over the past 31 years. However, due to the uneven spatial distribution of the population in developed cities, inequality among individuals has increased when resources are divided within 15-minute accessibility distance. We suggest that the government avoid policy lagging and reduce inequality by rationalizing the spatial configuration of socio-economic resources. Developed cities could adopt policies to direct the overpopulation of city centers outward, and developing cities should care about resources for suburban citizens.

社会经济资源的不平等威胁到个人福利和城市的可持续性。然而，不同资源配置情景下的不平等程度尚不清楚，且未考虑到资源的可达距离。在过去31年（1992-2022年）的15分钟城市中，我们开发了一个大规模、长期、多角度的资源分配和资源共享情景不平等定量评估框架。这一框架以城市发展模式以及资源和人口的空间分布为依据。来自中国334个城市的研究结果表明，发达城市和发展中城市的不平等程度存在差异。当个体在15分钟可达距离内共享资源时，由于资源在空间上更为平衡，发达城市的不平等程度低于发展中城市，且在过去31年中呈下降趋势。然而，由于发达城市人口空间分布的不均衡，当资源在15分钟可达距离内分配时，个体之间的不平等加剧。建议政府通过合理化社会经济资源的空间配置，避免政策滞后，减少不平等现象。发达城市可以采取政策引导城市中心的过剩人口向外转移，发展中城市应该关心郊区居民的资源。

Meeting China’s burgeoning food demand while safeguarding the resources and environmental long-term development is a critical challenge for the sustainable food systems of this century. China’s accelerated food imports have far-reaching implications for global resource allocation and environmental development. Hence, detailed information regarding China’s food trade resource-environmental impacts is imperative for the design of effective policies that promote environmental mitigation and resource conservation. This study estimated the spatial transfers of virtual water trade (VWT), virtual land trade (VLT), and virtual GHG emission trade (VGT) embodied in China’s food trade. Findings indicate that the VWT, VLT, and VGT transfers embodied in China’s food trade increased by 10.4 %, 9.8 %, and 15.2 % annually. It is more important to mention that virtual water import (VWI) and virtual land import (VLI) saved 119.5 × 10⁹m³ of global water resources and 29.5 Mha of land resources, respectively, but virtual GHG emission import (VGI) increased global 13 Mt CO₂-eq GHG emissions. The divergent impacts of China’s food import on global food sustainability stem from variations in virtual water content, yields and emission intensities. Moreover, significant differences in sustainability scores were found among the top 15 importing countries, indicating that China’s food trade contributes to the deepening of global food system sustainability. This study highlights the need for a multifaceted approach that considers the various environmental impacts of food trade. China is therefore encouraged to fully integrate the benefits of resource and environmental conservation into its sustainable food trade strategy, restructuring the food system to ensure the long-term nourishment of its large population.

在满足中国日益增长的粮食需求的同时，保障资源和环境的长期发展，是本世纪可持续粮食系统面临的重大挑战。中国粮食进口加速对全球资源配置和环境发展具有深远影响。因此，关于中国食品贸易资源环境影响的详细信息对于设计有效的促进环境缓解和资源保护的政策是必不可少的。研究估算了虚拟水交易、虚拟土地交易和虚拟温室气体排放交易在中国食品贸易中的空间转移。研究结果表明，中国食品贸易中体现的VWT、VLT和VGT转移年增长率分别为10.4%、9.8%和15.2%。值得一提的是，虚拟水进口（VWI）和虚拟土地进口（VLI）分别为全球节约了119.5 × 109m3的水资源和29.5 Mha的土地资源，但虚拟温室气体排放进口（VGI）却增加了全球13mt CO2-eq的温室气体排放。中国粮食进口对全球粮食可持续性的不同影响源于虚拟含水量、产量和排放强度的变化。此外，排名前15位的进口国在可持续性得分上存在显著差异，这表明中国的食品贸易对全球粮食系统可持续性的深化做出了贡献。这项研究强调需要采取多方面的方法，考虑粮食贸易的各种环境影响。因此，鼓励中国将资源和环境保护的好处充分纳入其可持续粮食贸易战略，重组粮食体系，以确保其庞大人口的长期营养。

Promoting positive urban–rural interactions is a key strategy for addressing rural decline and advancing regional sustainable development. This study examines the impacts of urban–rural interactions on rural development and explores their mechanisms for advancing sustainability within urban agglomeration areas. Using the Chang–Zhu–Tan (CZT) urban agglomeration as a case study, with an indicator system to measure urban–rural interactions and rural sustainable development, we analyze the mediating effects of resource flows in the process of urban–rural interactions driving rural sustainability through a mediation model. The results show that spatial connectivity, industrial convergence, and social integration between urban and rural areas positively contribute to the economic and social sustainability of rural areas. However, urban–rural spatial connectivity and social integration may negatively impact on rural environment. In this process, capital, technology, and labor play significant mediating roles, whereas the influence of land is less pronounced. Based on these findings, we propose several recommendations for strategically leveraging the benefits of urban–rural interactions across various social-ecological contexts while mitigating their drawbacks.

促进城乡良性互动是解决农村衰退、推进区域可持续发展的关键战略。本研究考察了城乡互动对农村发展的影响，并探讨了其促进城市群地区可持续发展的机制。以长株潭城市群为例，构建城乡互动与农村可持续发展测度指标体系，通过构建中介模型，分析城乡互动过程中资源流动对农村可持续发展的中介效应。研究结果表明，城乡空间连通性、产业融合和社会融合对农村经济社会可持续发展具有正向促进作用。然而，城乡空间连通性和社会一体化可能对农村环境产生负面影响。在这一过程中，资本、技术和劳动力的中介作用显著，而土地的中介作用不明显。基于这些发现，我们提出了一些建议，以战略性地利用城乡互动在各种社会生态背景下的好处，同时减轻其缺点。
