Sustainable agricultural production encounters significant challenges in balancing economic returns with environmental sustainability, particularly in the ecologically fragile dryland regions of Northwest China. This study employed life cycle assessment (LCA) and comprehensive evaluation index (CEI) to identify the optimal cropping system among potato continuous cropping (PC), wheat/green manure-potato (W_gP), pea/green manure-potato (P_gP), and wheat/green manure-pea/green manure-potato (W_gP_gP) in the study region. Furthermore, the non-dominated sorting genetic algorithm II (NSGA-II) was used to optimize regional cropping structure. The results indicated that crop rotations improved the soil health index by 13.1%–63.4%, increased the potato yield by 15.0%–38.2%, enhanced net economic benefits (NEB) by 30.6%–41.9%, and boosted net ecological economic benefits (NEEB) by 36.3%–47.6% compared to PC. Additionally, crop rotations reduced water consumption by 11.2%–26.1% and greenhouse gas (GHG) emissions by 33.6%–59.3%, while improving the potato nutrient use efficiency by 12.8%–38.4%. The CEI rankings indicated that P_gP (41.5%) was the highest, followed by W_gP_gP (33.2%), W_gP (17.3%), and PC (9.7%). Expanding the P_gP rotation in Northwest China could significantly reduce nutrient and water inputs, decrease GHG and reactive nitrogen (Nr) emissions, and enhance productivity and profitability. This study provides a practical pathway for sustainable food production in dryland agricultural regions by emphasizing the pivotal role of crop rotation in improving soil health and mitigating GHG and Nr emissions.

可持续农业生产在平衡经济效益和环境可持续性方面面临重大挑战，特别是在生态脆弱的西北旱地地区。采用生命周期评价（LCA）和综合评价指数（CEI）对研究区马铃薯连作（PC）、小麦/绿肥-马铃薯（WgP）、豌豆/绿肥-马铃薯（PgP）和小麦/绿肥-豌豆/绿肥-马铃薯（WgPgP）的最优种植制度进行了优选。采用非支配排序遗传算法II （NSGA-II）对区域种植结构进行优化。结果表明，轮作使土壤健康指数提高了13.1% ~ 63.4%，马铃薯产量提高了15.0% ~ 38.2%，净经济效益提高了30.6% ~ 41.9%，净生态经济效益提高了36.3% ~ 47.6%。此外，作物轮作减少了11.2% ~ 26.1%的水分消耗和33.6% ~ 59.3%的温室气体排放，提高了12.8% ~ 38.4%的养分利用效率。CEI排名显示，PgP最高（41.5%），其次是WgPgP（33.2%）、WgP（17.3%）和PC（9.7%）。在西北地区扩大PgP轮作可以显著减少养分和水分投入，减少温室气体和活性氮（Nr）排放，提高生产力和盈利能力。本研究通过强调轮作在改善土壤健康、减少温室气体和Nr排放中的关键作用，为旱地农业区的可持续粮食生产提供了切实可行的途径。

Root exudates (REs), a diverse array of bioactive metabolites secreted by plant roots in response to environmental stimuli, serve as key mediators of rhizosphere ecology and plant defense responses, offering a promising avenue for sustainable pest management and eco-friendly plant protection. While earlier reviews primarily focus on root exudates in the context of general rhizosphere dynamics and plant-microbial interactions, critical knowledge gaps persist in REs-plant-pest tripartite interactions, the mechanistic basis of REs-mediated plant defense, and their practical integration with integrated pest management (IPM) frameworks. This review provides a synthesis of the latest literature on the biochemical diversity and functions of REs, their environmentally-driven exudation dynamics, and their roles in induced systemic resistance (ISR) in plants and disrupting pest communication and development. Furthermore, we highlight their translational potential-including advances in RE-inspired green pesticide development, and emerging strategies that employ beneficial microorganisms to modulate REs profile for enhanced plant protection. By integrating these insights, this review underscores the potential of REs to redefine modern pest management strategies. We advocate for interdisciplinary research to further explore the ecological and evolutionary roles of REs, ultimately contributing to more resilient and sustainable agricultural systems.

根分泌物（Root exudates, REs）是植物根系在环境刺激下分泌的多种生物活性代谢物，是根际生态和植物防御反应的重要媒介，为害虫的可持续治理和生态友好型植物保护提供了一条有前景的途径。虽然早期的综述主要集中在根际动力学和植物-微生物相互作用的背景下的根分泌物，但在res -植物-害虫三方相互作用，res介导的植物防御的机制基础以及它们与综合虫害管理（IPM）框架的实际整合方面仍然存在关键的知识空白。本文综述了REs的生物化学多样性和功能、环境驱动的分泌动力学以及它们在植物诱导系统抗性（ISR）和破坏害虫交流和发育中的作用。此外，我们还强调了它们的转化潜力，包括re启发的绿色农药开发的进展，以及利用有益微生物调节re谱以增强植物保护的新兴策略。通过整合这些见解，本综述强调了可再生资源重新定义现代有害生物管理战略的潜力。我们提倡跨学科研究，以进一步探索可再生能源的生态和进化作用，最终为更具弹性和可持续性的农业系统做出贡献。

Urban water systems (UWSs) continuously evolve in response to changes in urban populations, technological advancements, and lifestyle shifts, resulting in significant changes in greenhouse gas (GHG) emissions. Understanding how GHG emissions vary across the different developmental stages of a UWS is crucial for charting pathways toward carbon neutrality under varying levels of urbanization and infrastructure maturity. To explore the long-term patterns of GHG emissions from the UWS, we developed a systematic accounting framework encompassing four energy-related subsystems: water extraction, water supply, residential water use, and wastewater treatment. We applied this framework to China’s UWS across its transitional trajectory—from early development to system-wide maturity (1980–2020) at the provincial level. Results show that over the 40 years, GHG emissions from China’s UWS increased approximately 14-fold, surpassing the overall rate of population growth by 143.9%. From the early 1990s till now, residential water use emerged as the dominant source of UWS-related emissions, accounting for approximately 77.6% of total emissions. Our scenario analysis estimates a potential 34.0% reduction in China’s carbon emissions (128.3 Mt CO₂-eq) by 2030 through water-saving strategies. This study offers critical insights into promoting low-carbon operations and sustainable management of UWS, and serves as an important reference for global efforts net-zero water infrastructure.

城市水系统（UWSs）随着城市人口、技术进步和生活方式的变化而不断发展，导致温室气体（GHG）排放发生重大变化。了解温室气体排放在UWS不同发展阶段的变化，对于绘制不同城市化水平和基础设施成熟度下的碳中和路径至关重要。为了探索UWS温室气体排放的长期模式，我们开发了一个系统的核算框架，包括四个与能源相关的子系统：取水、供水、住宅用水和废水处理。我们将这一框架应用于中国大学在省级层面的过渡轨迹——从早期发展到全系统成熟（1980-2020）。结果表明，在过去的40年中，中国UWS的温室气体排放量增长了约14倍，超过整体人口增长率143.9%。从20世纪90年代初至今，居民用水成为uws相关排放的主要来源，约占总排放量的77.6%。我们的情景分析估计，通过节水战略，到2030年中国的碳排放量可能减少34.0%（1.283亿吨二氧化碳当量）。本研究为促进水系统的低碳运营和可持续管理提供了重要见解，并为全球实现水基础设施净零提供了重要参考。

Livestock farming significantly contributes to anthropogenic greenhouse gas emissions and malodorous pollutants, exacerbating global environmental degradation. Despite the crucial role of protein feeds in regulating gas emissions and enhancing pork production efficiency, the mechanisms by which different protein feeds regulate odors remain unclear. This study employed an in vitro simulated fermentation and in vivo feeding trials to explore the effects of eight protein feeds in China on odor mitigation through regulation of pig gut microbiota. Results demonstrated that protein content and amino acid composition were key factors influencing odor emissions. Notably, the cottonseed meal group exhibited the highest levels of odor (68.67 ± 58.13 ppm) and showed enrichment of the genus Megasphaera. Correlation analysis revealed positive associations between Megasphaera and the production of

H_{2}

S, NH₃,

H_{2}

, and CO₂. KEGG pathway analysis indicated that the cottonseed meal group displayed a higher abundance of metabolic pathways compared to other experimental groups, with Megasphaera positively correlating with multiple metabolic pathways, including amino sugar and nucleotide sugar metabolism. In contrast, corn germ meal-H and rapeseed meal-J groups had lower odor levels (12 ± 5.33 ppm and 16.17 ± 6.18 ppm, respectively), negatively associated with Bacillus and unclassified_c__Bacilli. Additionally, feeding trials demonstrated that rapeseed meal-based feed reduced NH₃ and

H_{2}

S emissions in pig houses by 47.75% and 54.2%, respectively, without compromising pig production performance. These findings clarified protein feeds’ role in odor regulation and laid a scientific foundation for balancing pig industry sustainability and environmental degradation. However, odor metabolism molecular mechanisms in key bacteria and others still require in-depth study.

畜牧业在很大程度上造成了人为温室气体排放和恶臭污染物，加剧了全球环境退化。尽管蛋白质饲料在调节气体排放和提高猪肉生产效率方面发挥着至关重要的作用，但不同蛋白质饲料调节气味的机制尚不清楚。本研究通过体外模拟发酵和体内饲养试验，探讨8种中国产蛋白质饲料通过调节猪肠道菌群来缓解猪膻味的效果。结果表明，蛋白质含量和氨基酸组成是影响气味释放的关键因素。值得注意的是，棉籽粕组表现出最高的气味水平（68.67±58.13 ppm），并且显示出Megasphaera属的富集。相关分析显示，Megasphaera与H2S、NH3、H2和CO2的产量呈正相关。KEGG通路分析表明，棉籽粕组代谢途径丰度高于其他试验组，其中巨藻与多种代谢途径呈正相关，包括氨基糖和核苷酸糖代谢。玉米胚芽粕- h组和菜籽粕- j组的气味水平较低（分别为12±5.33 ppm和16.17±6.18 ppm），与芽孢杆菌和未分类芽孢杆菌呈负相关。此外，饲养试验表明，油菜籽粕基饲料在不影响猪生产性能的情况下，可使猪舍内NH3和H2S排放量分别降低47.75%和54.2%。这些发现阐明了蛋白质饲料在气味调节中的作用，为平衡养猪业可持续性和环境退化奠定了科学基础。然而，关键细菌等的气味代谢分子机制仍需深入研究。

A large proportion of human population could be exposed to future risks from compound climate extremes, which are threatening food and water security. To understand the far-reaching impacts of these extremes on the livelihoods of current and future generations, we need models that are less ambiguous, better suited for impact studies, and more capable of advancing our understanding of future climatic conditions (e.g., rainfall and temperature). To advance such modelling capabilities for impact assessment of compound extremes in Australia, we develop a new framework to combine satellite gravity data with in-situ data and outputs from hydrological models to adjust for biases in the latest Coupled Model Intercomparison Project Phase general circulation models’ projections of water budget parameters. The impacts of compound climate extremes under different climate scenarios on the freshwater derived from these parameters were then assessed. Our findings show that the Australian east coast will experience a rise in compound hot and wet extremes, and changes to these compound extremes under different climate scenarios will drive freshwater deficits in Australia. The consequences of limiting global warming to different levels (historical, SSP 245, 370, and 585) on freshwater were also identified. We found significant freshwater declines over Australia with Western Australia being the most affected by compound climate extremes (wet and hot extremes) across all global warming scenarios. Considerable percentage changes exceeding -125% in freshwater have been linked to these compound extremes. Our results also reveal that evapotranspiration will emerge as a more crucial indicator to freshwater availability, and that atmospheric dynamics and moisture transport are expected to contribute to considerable changes in freshwater availability.

很大一部分人口未来可能面临复合极端气候带来的风险，这将威胁到粮食和水安全。为了了解这些极端事件对当代人和子孙后代生计的深远影响，我们需要不那么模糊、更适合影响研究、更有能力推进我们对未来气候条件（如降雨和温度）理解的模型。为了提高澳大利亚复合极端天气影响评估的建模能力，我们开发了一个新的框架，将卫星重力数据与原位数据和水文模型的输出相结合，以调整最新的耦合模式比对项目阶段一般环流模型对水收支参数预测的偏差。然后评估了不同气候情景下的复合极端气候对由这些参数得到的淡水资源的影响。我们的研究结果表明，澳大利亚东海岸将经历复合极端炎热和极端潮湿的增加，在不同的气候情景下，这些复合极端天气的变化将导致澳大利亚的淡水短缺。还确定了将全球变暖限制在不同水平（历史、SSP 245、370和585）对淡水的影响。我们发现澳大利亚的淡水资源显著减少，在所有全球变暖情景中，西澳大利亚受复合极端气候（极端潮湿和极端炎热）的影响最大。淡水中超过-125%的相当大的百分比变化与这些复合极端有关。我们的研究结果还表明，蒸散发将成为淡水可用性的一个更重要的指标，并且大气动力学和水分输送预计会导致淡水可用性的相当大的变化。

Worsening water shortages due to climate change have underscored the need for sustainable agricultural practices, including mulching, to restore soil moisture and health. Environmental concerns associated with plastic mulching materials in agriculture have prompted the adoption of biodegradable alternatives. Topsoil cover (TSC), developed through the valorization of wood industry by-products and xanthan gum, offers a sustainable solution. Indigenous microbiomes, predominantly Proteobacteria (e.g., Pseudomonas spp.), Firmicutes (e.g., Staphylococcus spp.), and Aspergillus spp., can biodegrade TSC under controlled condition. Germination tests confirm its effectiveness in weed control. A greenhouse experiment using tomato (Solanum lycopersicum) demonstrated that TSC enhances shoot and root length by 50 and 100%–160% and overall biomass by 30%–50%, without altering rhizosphere soil physicochemical properties or microbial community structure. Additionally, the reversible effect of TSC can enhance the early soil nitrogen pool by 20% through microbial interactions.

气候变化造成的日益严重的水资源短缺突出表明，需要采用可持续的农业做法，包括覆盖，以恢复土壤水分和健康。农业中与塑料覆盖材料有关的环境问题促使人们采用可生物降解的替代品。表层土壤覆盖物（TSC）是通过木材工业副产品和黄原胶的增值而开发的，提供了一种可持续的解决方案。本地微生物群，主要是变形菌门（如假单胞菌）、厚壁菌门（如葡萄球菌）和曲霉，可以在受控条件下生物降解TSC。发芽试验证实了其控制杂草的有效性。温室试验表明，在不改变根际土壤理化性质和微生物群落结构的情况下，TSC可使番茄（Solanum lycopersicum）的茎长和根长分别增加50%和100% ~ 160%，总生物量增加30% ~ 50%。此外，TSC的可逆效应可以通过微生物相互作用使早期土壤氮库增加20%。它还增加了土壤微生物代谢的多样性，突出了其农业利用的潜力。我们的研究结果表明，TSC是一种创新产品，可以在提高土壤肥力、促进植物健康和实现木材中期碳储存的同时，完成木材工业废物的循环。

Addressing escalating land use conflicts (LUCs) is critical for sustainable development in resource-scarce, transboundary regions. The Aral Sea Basin (ASB), Central Asia’s largest transboundary basin characterized by arid conditions and vulnerable ecosystems, serves as a crucial case study. This research introduces an innovative framework, integrating multi-scale spatial assessments with interpretable machine learning (XGBoost-SHAP), to overcome limitations of previous fragmented analyses and provide deeper insights into LUCs dynamics. We systematically evaluated land suitability for ecological preservation, agriculture, and urban construction, quantified conflict intensity, and identified key drivers across the entire ASB, including its Amu Darya and Syr Darya sub-basins. Quantitative results reveal profound spatial heterogeneity in land use potential, with 56.29% of the basin suitable for ecological preservation, only 6.54% for agriculture, and 72.67% for urban construction—indicating dominant ecological value, limited agricultural suitability, and high urban development pressure. Conflicts were found to be pervasive and intense, driven by a complex interplay of natural factors and socio-economic pressures, with distinct upstream-downstream patterns across sub-basins. Crucially, this study provides spatially explicit evidence highlighting the urgent need for integrated, transboundary land management. The results offer actionable, data-driven insights essential for designing targeted strategies, fostering collaborative resource governance, and ultimately promoting sustainable development pathways that balance ecological integrity with human needs in the ASB and similar complex transboundary basins worldwide.

解决不断升级的土地利用冲突对资源稀缺的跨界地区的可持续发展至关重要。咸海盆地（ASB）是中亚最大的跨界盆地，其特点是干旱条件和脆弱的生态系统，是一个重要的案例研究。本研究引入了一个创新的框架，将多尺度空间评估与可解释性机器学习（XGBoost-SHAP）相结合，以克服以往碎片化分析的局限性，并为lucc动态提供更深入的见解。我们系统地评估了生态保护、农业和城市建设的土地适宜性，量化了冲突强度，并确定了整个ASB的关键驱动因素，包括阿姆河和锡尔河子流域。定量结果显示，流域土地利用潜力空间异质性较强，生态保护用地占56.29%，农业用地占6.54%，城市用地占72.67%，生态价值占主导地位，农业用地适宜性有限，城市发展压力较大。在自然因素和社会经济压力复杂的相互作用下，冲突普遍而激烈，各子盆地的上下游格局明显。至关重要的是，这项研究提供了空间上明确的证据，强调了综合跨境土地管理的迫切需要。研究结果提供了可操作的、数据驱动的见解，对于设计有针对性的战略、促进资源协作治理，并最终促进平衡ASB和全球类似复杂跨界流域的生态完整性与人类需求的可持续发展路径至关重要。

The agricultural sector plays a pivotal role in the carbon cycle, making the evaluation of the food–climate nexus essential for effective mitigation policy. This study assesses greenhouse gas (GHG) emission dynamics across the European Union (EU-27) from 1990 to 2021. While 20 of the 27 countries showed significant reductions in emissions (p < 0.05), Mann–Kendall trend analysis revealed an overall significant decline (p < 0.0001), with a Sen’s slope of −2,190 kt CO₂ eq/year. Land use data from CORINE indicated a modest 0.08% expansion in agricultural land, primarily non-irrigated arable land, resulting in a net gain of 2.27 million hectares. Autoregressive distributed lag modeling revealed a short-run reduction (−0.07%) but a long-run increase (＋0.15%) in GHG emissions linked to agricultural land expansion. Granger causality analysis identified strong unidirectional relationships from agricultural drivers—including land use, value-added agriculture, crop and livestock production, and fertilizer use—to emissions. Notably, forest area increased by 12%, contributing to significant emission reductions, and showed bidirectional causality with agricultural land. These results exposed a persistent gap between emission trends and policy targets, recommending for countries and sector-specific interventions in agriculture, livestock, and land-use governance.

农业部门在碳循环中发挥着关键作用，因此评估粮食-气候关系对于制定有效的减缓政策至关重要。本研究评估了1990年至2021年整个欧盟（EU-27）的温室气体排放动态。虽然27个国家中有20个国家的排放量大幅减少(p <；0.05)， Mann-Kendall趋势分析显示整体显著下降(p <；0.0001)， sens斜率为- 2190 kt CO2当量/年。CORINE的土地利用数据显示，农业用地（主要是非灌溉耕地）适度增长了0.08%，净增长227万公顷。自回归分布滞后模型显示，与农业用地扩张相关的温室气体排放短期减少（- 0.07%），但长期增加（+0.15%）。格兰杰因果分析发现，农业驱动因素（包括土地利用、增值农业、作物和牲畜生产以及化肥使用）与排放之间存在很强的单向关系。森林面积增加了12%，对减排贡献显著，且与农用地呈双向因果关系。这些结果揭示了排放趋势与政策目标之间的持续差距，并建议各国和部门在农业、畜牧业和土地利用治理方面采取具体干预措施。

Development of wet peatland innovation (Paludiculture) offers significant potential for the alternative and sustainable use of land for addressing new viable commercial green opportunities. However, the lack of appropriate demonstration facilities has limited the development of Paludiculture. There is a substantial knowledge gap surrounding the design, tangible use and scaling of novel bioeconomy demonstration sites to meet emerging paludiculture innovation and for tailoring strategic policies to unlock regulatory shortcomings. This review addresses the important development of a novel integrated multitrophic aquaculture (IMTA) site for demonstrating paludiculture innovation at scale in rewetted peatlands. It addresses novel enablers, drivers and shortcomings for advancing emerging bioeconomy needs using a Penta-helix multiactor framework that meets effective resource management, biomass recycling, pollution control, sustainable production, risk management and predictability. Findings revealed that duckweed growth from this IMTA site (ca. area of 12,800 m²) can remediate 0.78 T yr ⁻¹ of total nitrogen and 0.38 T yr ⁻¹ of total phosphorous from fish waste stream yielding ca. 500 T per yr ⁻¹ duckweed biomass of high protein content (21.84 ± 2.45%). Next generation sequencing and bioinformatic analysis of Illumina and MinION data from the channels revealed a total of 982 species from 341 genera across nine phyla of microalgae that offer future potential to be biorefined on site for new high value products. Additionally, identification of specific microalgae and/or bacterial species can be used as early warning bioindicators of unwanted flux in the defined IMTA ecosystem, such as the impact of extreme weather events on aquaculture. Implications of findings support a strong alignment with zero-waste and zero-pollution principles and will contribute to achieving many of the United Nation’s Sustainable Development Goals. This integrated approach provides a novel IMTA blueprint for replicating paludiculture innovation in other demonstration locations globally that will be informed by future tailored life cycle assessment along with end-user evaluation and monitoring needs that addresses circularity, environmental and social impacts.

湿泥炭地创新（Paludiculture）的发展为土地的替代和可持续利用提供了巨大的潜力，以解决新的可行的商业绿色机会。然而，缺乏适当的示范设施，限制了古乐文化的发展。围绕新型生物经济示范点的设计、实际使用和规模，以满足新兴的生物农业创新，以及定制战略政策以解决监管缺陷，存在着巨大的知识缺口。本文综述了一种新型综合多营养水产养殖场（IMTA）的重要发展，以展示复湿泥炭地大规模的养殖创新。它利用五螺旋多因素框架，解决了推动新兴生物经济需求的新促成因素、驱动因素和缺点，满足了有效的资源管理、生物质回收、污染控制、可持续生产、风险管理和可预测性。结果表明，在该IMTA场地（面积为12,800 m2）生长的浮萍可修复鱼类废物流中0.78 T yr−1的总氮和0.38 T yr−1的总磷，产生约500 T / yr−1的高蛋白含量浮萍生物量（21.84±2.45%）。下一代测序和Illumina和MinION通道数据的生物信息学分析显示，来自9门341属的微藻共982种，为未来的高价值产品提供了生物精炼的潜力。此外，鉴定特定的微藻和/或细菌种类可作为确定的海洋生态系统中有害通量的早期预警生物指标，例如极端天气事件对水产养殖的影响。调查结果的含义支持与零废物和零污染原则的紧密一致，并将有助于实现联合国的许多可持续发展目标。这种综合方法为在全球其他示范点复制农业创新提供了新的IMTA蓝图，未来将根据量身定制的生命周期评估以及解决循环、环境和社会影响的最终用户评估和监测需求提供信息。

In the post-epidemic era, the domestic market as the mainstay in China is signifying a shift whereby interregional trade supersedes international trade as the pivotal driver of regional sustainable development. Thus, the scientific understanding of interregional natural resource flows within China is crucial. This study refers to the human appropriation of net primary production (HANPP) framework to construct indicators to extend the multi-regional input–output (MRIO) table. This table is then used to explore the interprovincial flow patterns and their determinants of ecological resources in China. The results show that: (1) Ecological resource flow in China predominantly moves from western inland regions to eastern coastal regions, yet the interplay among provinces is evolving into a more intricate pattern. (2) Agricultural production intensity, ecological resource endowment, and geographic distance are consistent and significant factors influencing ecological resource flow patterns. (3) Structural adjustments in ecological resource production or consumption primarily drove changes in net ecological resource flows from 2012 to 2017. Production structural changes in nearly half of the provinces initiated a decoupling of economic development from ecological resources. Meanwhile, consumption structural changes in economically developed provinces steered regional consumption patterns towards greater sustainability. These insights can offer scientific support for the integration of interregional ecological resource mobilization pathways for regional sustainable development in China.

疫情后时代，以国内市场为主体的中国，标志着区域间贸易取代国际贸易成为区域可持续发展的核心驱动力的转变。因此，对中国区域间自然资源流动的科学认识至关重要。本文采用净初级生产的人为占用（HANPP）框架构建指标，扩展了多区域投入产出（MRIO）表。然后利用这个表来探讨中国生态资源的省际流动模式及其决定因素。结果表明：①中国生态资源流动以西部内陆地区向东部沿海地区转移为主，但省际间的相互作用格局日趋复杂；(2)农业生产强度、生态资源禀赋和地理距离是影响生态资源流动模式的一致且显著的因素。(3) 2012 - 2017年，生态资源生产或消费结构调整是生态资源净流量变化的主要驱动因素。近一半省份的生产结构发生变化，导致经济发展与生态资源脱钩。与此同时，经济发达省份的消费结构变化使区域消费模式朝着更可持续的方向发展。这些见解可为中国区域可持续发展的区域间生态资源动员路径整合提供科学支持。
