Understanding carbon generation from Individual Travel Activities (ITAs) requires moving beyond aggregate household or per-capita measures to examine frequency distributions across diverse set of trip characteristics. Yet, current research lacks a well-established empirical framework operating at a disaggregated level to profile the relationship between ITAs and carbon generation. Drawing on household travel survey data for South East Queensland, Australia, this study details a frequency-distribution modelling approach that employs the Lévy distribution to characterise how carbon generation varies across ITAs. The method enhances existing carbon estimation practices beyond traditional mean-based or aggregate approaches. A seven-parameter framework derived from normal-Lévy distribution coefficients captures the relationship between travel frequency and carbon generation, enabling systematic comparison across travel modes, purposes, and household locations. The model empirically derives carbon generation thresholds (2.88 kg CO₂ per trip) to distinguish between intra-urban and inter-city trips, replacing administratively-defined boundaries with a data-driven spatial delineation alternative. Results reveal that while 83.5 % of trips generate relatively low carbon emission (no more than 2.88 kg per trip), these frequent, low intensity intra-urban activities constitute the majority of total carbon generation, challenging the typical conventional focus on high-emission trip reduction. This frequency-distribution approach provides urban planners and policymakers with an empirical framework for quantifying carbon impacts at the ITA level through which tailored interventions can be designed to encourage a shift to lower-carbon alternatives.

了解个人旅行活动（ita）产生的碳需要超越总体家庭或人均措施，以检查不同旅行特征的频率分布。然而，目前的研究缺乏一个在分类水平上运作的成熟的经验框架来描述ita与碳生成之间的关系。根据澳大利亚昆士兰东南部的家庭旅行调查数据，本研究详细介绍了一种频率分布建模方法，该方法采用lsamvy分布来描述不同地区碳排放量的变化。该方法增强了现有的碳估算实践，超越了传统的基于均值或聚合的方法。从正态lsamv分布系数推导出的七参数框架捕捉了旅行频率和碳产生之间的关系，从而能够系统地比较旅行方式、目的和家庭位置。该模型通过经验推导出碳产生阈值（每趟2.88千克二氧化碳），以区分城市内和城市间的旅行，用数据驱动的空间描绘替代行政定义的边界。结果表明，尽管83.5%的出行产生的碳排放量相对较低（每次出行不超过2.88 kg），但这些频繁、低强度的城市内部活动构成了碳排放总量的大部分，挑战了传统上对高排放出行减少的关注。这种频率分布方法为城市规划者和决策者提供了一个量化ITA层面碳影响的经验框架，通过该框架，可以设计有针对性的干预措施，鼓励向低碳替代方案的转变。

The critical role of manufacturing agglomeration (MA) in promoting high-quality economic development (HED) is widely recognized in both academic and policy discourse. However, the nonlinear effects and spatial spillover mechanisms by which MA affects HED have not been sufficiently addressed in the existing literature. Using panel data from 287 prefecture-level and above cities in China from 2011 to 2023, this study adopts spatiotemporal analysis to trace the evolution of MA and HED, and employs fixed-effects models, mediation analysis, and spatial Durbin models to examine the multidimensional mechanisms linking the two. The results reveal steady improvements in both MA and HED, marked by an east–west gradient and a spatial transition from initial concentration to a more balanced and polycentric structure. A significant U-shaped relationship is identified, indicating that MA initially suppresses but later promotes HED as agglomeration intensity increases. Furthermore, MA indirectly facilitates HED by enhancing urban logistics development, which improves factor allocation and industrial connectivity. Spatial analysis confirms a U-shaped spillover effect on neighboring cities—initially driven by negative externalities such as resource competition and siphoning effects, and subsequently transformed into positive interactions through coordinated specialization and knowledge diffusion. Heterogeneity analysis shows that the impact of MA varies significantly across regions, city tiers, resource endowments, urban agglomeration status, and industry types. This study not only deepens the theoretical understanding of the nexus between MA and HED but also offers valuable insights for other countries seeking to optimize industrial spatial layouts and foster coordinated regional development.

制造业集聚在促进高质量经济发展中的重要作用已得到学术界和政策界的广泛认可。然而，在现有文献中，MA影响HED的非线性效应和空间溢出机制尚未得到充分的研究。本文利用2011 - 2023年中国287个地级市及以上城市的面板数据，采用时空分析方法追溯城市人口流动和城市人口流动的演变过程，并运用固定效应模型、中介分析和空间Durbin模型考察两者之间的多维关联机制。研究结果显示，MA和HED均有稳定的改善，表现为东西梯度和从初始集中到更平衡和多中心结构的空间过渡。发现了显著的u型关系，表明随着团聚强度的增加，MA先抑制HED，后促进HED。此外，MA通过促进城市物流发展，间接促进了HED，从而改善了要素配置和产业连通性。空间分析证实了对相邻城市的u型溢出效应——最初由资源竞争和虹吸效应等负外部性驱动，随后通过协调的专业化和知识扩散转化为正相互作用。异质性分析表明，MA的影响在区域、城市层级、资源禀赋、城市群状况和产业类型之间存在显著差异。本研究不仅加深了对MA与HED关系的理论认识，也为其他国家优化产业空间布局、促进区域协调发展提供了有价值的启示。

Ecological compensation in river basins serves as an important means to mitigate the deterioration of water quality and safeguard ecological flows, playing a crucial role in integrated basin management. Taking the Wuding River Basin as the study area, this research, from the perspective of an internal symbiotic system, constructs an integrated management framework encompassing both water quantity and water quality compensation. Shadow project method and game theory are employed to determine compensation standards and compensation models, thereby exploring pathways for integrated basin governance. The results show that Yuyang District bears 35 % of the economic responsibility for water quantity compensation expenditures. In terms of water quality compensation, both pollution control efforts and regional economic benefits under the ecological compensation scenario are significantly higher than those under the no-compensation scenario. Moreover, central intervention is not always the optimal strategy; when

γ_{d o w n} > 3 γ_{u p}

, the master-slave game cooperation model proves more effective in maximizing overall benefits. A cooperative relationship based on dual ecological compensation provides an effective solution for promoting the high-quality development of the entire basin. These findings provide scientific reference for the formulation of ecological compensation policies and integrated water resources management.

流域生态补偿是缓解水质恶化、保障生态流量的重要手段，在流域综合管理中具有重要作用。本研究以无定河流域为研究区，从内部共生系统的角度，构建了水量补偿与水质补偿并重的综合管理框架。运用影子项目法和博弈论确定补偿标准和补偿模式，探索流域一体化治理的路径。结果表明，玉阳区承担了水量补偿支出的35%的经济责任。在水质补偿方面，生态补偿情景下的污染治理力度和区域经济效益均显著高于无补偿情景。此外，中央干预并不总是最优策略；当γ向下>；3γ向上时，主从博弈合作模型在整体利益最大化方面更为有效。基于双重生态补偿的合作关系，为促进整个流域的高质量发展提供了有效的解决方案。研究结果可为生态补偿政策的制定和水资源综合管理提供科学参考。

Accessibility, as a manifestation of the right to the city, plays a pivotal role in assessing social equity and spatial justice. Accurate accessibility measurements are critical for guiding equitable urban planning. Conventional accessibility metrics focus on physical environmental characteristics, while recent advancements increasingly incorporate perceptions of the built environment. However, existing advancements mainly adopt an outcome-based approach, neglecting the underlying mechanism through which physical environmental characteristics translate into perceptions. Decoding this perceptual process is vital for refining accessibility measurements and achieving more comprehensive, accurate results. This study re-understands accessibility by proposing a conceptual framework incorporating perception mechanisms rooted in cognitive process theories. The framework delineates how individuals gather spatial information to identify opportunities at origins, destinations, and during travel, which are then filtered through constraints, attitudes, and habits. We empirically validate this framework using social sensing data to evaluate restaurant accessibility in Shenzhen, China. Our case study reveals that conventional accessibility metrics tend to overestimate individuals' access to potential opportunities. The proposed framework is quantifiable, interpretable, and scalable across diverse contexts. By bridging the gap between the physical environment and perceptual outcomes, it advances a new understanding of accessibility that integrates perception into measurement, offering valuable insights for equitable planning and policy-making.

可达性作为城市权利的表现形式，在评估社会公平和空间正义方面发挥着关键作用。准确的可达性测量对于指导公平的城市规划至关重要。传统的可达性指标侧重于物理环境特征，而最近的进展越来越多地纳入了对建筑环境的看法。然而，现有的进展主要采用基于结果的方法，忽视了物理环境特征转化为感知的潜在机制。解码这一感知过程对于完善可访问性测量和获得更全面、更准确的结果至关重要。本研究以认知过程理论为基础，提出了一个包含感知机制的概念框架，重新理解可及性。该框架描述了个体如何收集空间信息，以识别在起点、目的地和旅行过程中的机会，然后通过约束、态度和习惯过滤这些信息。我们使用社会感知数据对该框架进行实证验证，以评估中国深圳的餐厅可达性。我们的案例研究表明，传统的可访问性指标倾向于高估个人对潜在机会的访问。所提出的框架是可量化的、可解释的，并且可以在不同的上下文中扩展。通过弥合物理环境与感知结果之间的差距，该研究推进了对可达性的新理解，将感知与测量相结合，为公平规划和政策制定提供了宝贵的见解。

Understanding the varying degrees of synergies and trade-offs among Sustainable Development Goals (SDGs), as well as the influential goals within these interactions, is crucial for identifying transformative governance actions. However, the spatiotemporal dynamics of SDG interactions and priorities remain unclear. Here, we analyzed global and regional variations in SDG interactions, synergistic performance, and key contributing goals from 2000 to 2022 using network methodology, index analysis, and machine learning. Europe exhibited high SDG synergies, low synergy-network modularity, and strong synergistic performance, while Western Asia showed the opposite pattern. Despite overall improvement in SDG synergy proportions and synergistic performance, global progress was constrained by declining synergies related to SDG 5 (gender equality) and increasing fragmentation of the SDG synergy network. We also observed substantial spatio-temporal changes in the impact of each SDG within the interaction network and in its contribution to overall synergistic performance. Furthermore, we applied an ensemble random forest model to assess SDG mentions and co-occurrences in 1944 SDG interaction studies. SDGs 13 (climate action) and 9 (industry, innovation and infrastructure) emerged as the most and least frequently discussed goals, respectively. Interactions among seven SDGs (2, 6, 7, 8, 12, 13, 15) formed a typical SDG nexus, reflecting a critical human-nature relationship chain. Overall, to advance global SDG attainment, we emphasize the importance of accelerating progress on SDG 3 (good health and well-being). Our study enhances understanding of global development patterns and priorities and supports efforts to rescue the 2030 Agenda.

了解可持续发展目标（sdg）之间不同程度的协同作用和权衡，以及这些相互作用中的有影响力的目标，对于确定变革性治理行动至关重要。然而，可持续发展目标相互作用的时空动态和优先事项仍不清楚。在这里，我们使用网络方法、指数分析和机器学习分析了2000年至2022年可持续发展目标相互作用、协同绩效和关键贡献目标的全球和地区差异。欧洲表现出高的可持续发展目标协同性、低的协同网络模块化和强的协同绩效，而西亚表现出相反的模式。尽管可持续发展目标协同比例和协同绩效总体上有所改善，但与可持续发展目标5（性别平等）相关的协同效应下降，以及可持续发展目标协同网络日益碎片化，制约了全球进展。我们还观察到，每个可持续发展目标在互动网络中的影响及其对整体协同绩效的贡献存在显著的时空变化。此外，我们应用了一个集合随机森林模型来评估1944年可持续发展目标相互作用研究中提到的可持续发展目标和共同出现的情况。可持续发展目标13（气候行动）和9（工业、创新和基础设施）分别成为讨论次数最多和最少的目标。7个可持续发展目标（2、6、7、8、12、13、15）之间的相互作用形成了一个典型的可持续发展目标联结，反映了一个关键的人与自然关系链。总体而言，为推动全球实现可持续发展目标，我们强调必须加快实现可持续发展目标3（良好健康和福祉）。我们的研究增进了对全球发展模式和优先事项的理解，并支持挽救2030年议程的努力。

Understanding the spatial non-stationarity of industrial pollution's impact on cancer prevalence is crucial for targeted surveillance. This study examines the spatial non-stationarity of localized industrial point source emissions on regional colorectal cancer (CRC) patterns, utilizing a novel spatial coupling framework that integrates an exposure population-weighted assessment model (EPAM) with multiscale geographically weighted regression (MGWR). The key findings are as follows: First, we demonstrate that the association between metal surface treatment industry (MSTI) emissions and CRC is most accurately captured at a fine, localized scale of population exposure, a dimension obscured by conventional regional-aggregate or proximity-based exposure proxies. Further, our analysis reveals significant spatial non-stationarity, wherein the influence of MSTI emissions on CRC is concentrated in specific high-risk clusters, which primarily industrialized cities along China's southeastern coast. This spatial non-stationarity arises from the convergence of large-scale industrial pollution emissions, terrain favorable to pollutant dispersion, and high population density. Crucially, this EPAM-MGWR coupled framework quantifies localized exposure with a small-scale bandwidth, outperforming conventional medium-to-large-scale exposure proxies by enhancing the explained variance in CRC spatial patterns by 22 %–83 % compared to traditional Geographically Weighted Regression. In sum, these findings indicate that the carcinogenic impact of industrial pollution is a localized process, whose accurate detection at the regional level requires an analytical framework that reconciles the fine-grained emission dispersion with the multiscale health determinants. The coupling framework developed in this study offers a broadly applicable technical approach for examining the spatial associations between industrial point source pollution and various cancer types.

了解工业污染对癌症患病率影响的空间非平稳性对于有针对性的监测至关重要。本研究利用一种新的空间耦合框架，将暴露人口加权评估模型（EPAM）与多尺度地理加权回归（MGWR）相结合，研究了局部工业点源排放对区域结直肠癌（CRC）模式的空间非平定性。主要发现如下：首先，我们证明了金属表面处理工业（MSTI）排放与CRC之间的联系最准确地体现在精细的局部人口暴露尺度上，这一维度被传统的区域总体或基于邻近的暴露代理所掩盖。此外，我们的分析还揭示了显著的空间非平稳性，其中MSTI排放对CRC的影响集中在特定的高风险集群中，主要是中国东南沿海的工业化城市。这种空间上的非平稳性源于大规模工业污染排放的趋同、有利于污染物扩散的地形和较高的人口密度。至关重要的是，这种EPAM-MGWR耦合框架量化了小范围带宽的局部暴露，与传统的地理加权回归相比，通过将CRC空间模式的解释方差提高22% - 83%，优于传统的中大规模暴露代理。总之，这些研究结果表明，工业污染的致癌影响是一个局部过程，其在区域一级的准确检测需要一个分析框架，以协调细粒度排放分散与多尺度健康决定因素。本研究建立的耦合框架为研究工业点源污染与各种癌症类型之间的空间关联提供了一种广泛适用的技术方法。

In sum, these findings indicate that the carcinogenic impact of industrial pollution is a localized process, whose accurate detection at the regional level requires an analytical framework that reconciles the fine-grained emission dispersion with the multiscale health determinants. The coupling framework developed in this study offers a broadly applicable technical approach for examining the spatial associations between industrial point source pollution and various cancer types.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"186 ","pages":"Article 103823"},"PeriodicalIF":5.4,"publicationDate":"2025-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145419313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transition to clean energy and more sustainable production is reconfiguring labor markets. However, jobs associated with this process—broadly categorized as green jobs—do not always align with the existing capabilities of diverse labor markets. This study critically examines the development of the green hydrogen industry in Chile, focusing on its introduction in the Magallanes region and the accompanying promises of job creation. Employing a geographical political economy lens, the analysis explores the tensions between narratives and projections of job creation for the region and their alignment with the local labor market, as well as how these tensions intersect with the multi-scalar uncertainties surrounding the industry. Drawing on semi-structured interviews with key stakeholders from the private and public sectors, alongside job creation data projections, the study interrogates the concept of “green jobs” within the framework of Chile's national green hydrogen policy. Uncertainties surrounding the industry's development and potential scale in Magallanes amplify expectations and controversies about its contribution to the regional economy. Key controversies include the alignment of the regional labor market with the industry's labor demands, the quality and stability of the jobs promised, and the potential impacts of technologies enabling remote work and long-distance commuting on the regional economy. This critique challenges the promises of green industrialization by situating them within broader trajectories of inequality and dependency.

向清洁能源和更可持续生产的转型正在重新配置劳动力市场。然而，与这一过程相关的工作——被广泛地归类为绿色工作——并不总是与多样化劳动力市场的现有能力相一致。本研究批判性地考察了智利绿色氢工业的发展，重点关注其在麦哲伦地区的引入以及随之而来的创造就业机会的承诺。采用地理政治经济学的视角，该分析探讨了该地区创造就业机会的叙述和预测之间的紧张关系，以及它们与当地劳动力市场的一致性，以及这些紧张关系如何与围绕该行业的多标量不确定性交叉。通过对私营和公共部门主要利益相关者的半结构化访谈，以及创造就业机会的数据预测，该研究在智利国家绿色氢政策的框架内对“绿色就业”的概念进行了质疑。围绕麦哲伦岛旅游业发展和潜在规模的不确定性，加大了人们对其对地区经济贡献的期望和争议。主要争议包括区域劳动力市场与行业劳动力需求的一致性，所承诺工作的质量和稳定性，以及远程工作和长途通勤技术对区域经济的潜在影响。这种批评通过将绿色工业化的承诺置于更广泛的不平等和依赖的轨迹中来挑战它们。

Effective conservation in protected areas (PAs) heavily depends on public participation. Generation Z exhibits heightened ecological concern and a greater willingness to engage in environmental protection. From the perspective of geography and sociology, this study investigates the spillover of environmental protection from PAs to daily life among Generation Z. A survey of 396 undergraduate and graduate students demonstrates this positive behavioral spillover, which is attenuated by environmental knowledge. The study further identifies the dual mediating roles of environmental self-identity and group identity in the relationship between PA-based and daily environmental protection. These findings highlight the importance of fostering consistent environmental practices across different spatial contexts, providing theoretical insights and practical implications for enhancing the sustainability of Generation Z's engagement in environmental protection.

保护区的有效保护在很大程度上取决于公众的参与。Z世代表现出高度的生态关注和更大的环保意愿。本研究从地理学和社会学的角度考察了z世代从个人行为到日常生活的环境保护溢出效应。对396名本科生和研究生的调查表明，这种积极的行为溢出效应被环境知识所减弱。本研究进一步发现环境自我认同和群体认同在pa基础与日常环境保护关系中的双重中介作用。这些发现强调了在不同的空间背景下培养一致的环境实践的重要性，为提高Z世代参与环境保护的可持续性提供了理论见解和实践意义。

Research on local climate governance is dominated by the epistemologies of large cities and affluent areas, casting less urbanised, structurally disadvantaged, and peripheral localities as ‘laggards’. This mirrors economic-geography narratives that depict ‘left-behind’ areas as politically regressive and institutionally deficient. This article problematises that narrative by theorising peripheral climate leadership and demonstrating its empirical prevalence. It introduces a research strategy for systematically detecting and examining climate strategies and governance leaders in ‘left-behind’ settings. Empirically, analysis of 323 UK local authorities outside Greater London identifies 110 economically disadvantaged non-metropolitan councils, 26 of which rank in the national top decile in at least one climate-policy domain. These results suggest a more variegated geography of climate leadership, shaped by a contingent interplay of economic legacy, political agency, and governance innovation. Recognising these ‘unlikely’ climate pioneers reorients local governance scholarship and positions peripheral areas as pivotal actors in accelerating net-zero transitions.

关于地方气候治理的研究主要以大城市和富裕地区的认识论为主导，将城市化程度较低、结构上处于不利地位和边缘地区视为“落后者”。这反映了将“落后”地区描述为政治倒退和制度缺陷的经济地理学叙事。本文通过对周边气候领导力进行理论化并展示其经验普遍性，对这种说法提出了质疑。它介绍了一项研究战略，用于系统地检测和审查“落后”国家的气候战略和治理领导人。根据经验，对大伦敦以外的323个英国地方当局的分析，确定了110个经济上处于不利地位的非大都市议会，其中26个在至少一个气候政策领域排名全国前十分之一。这些结果表明，经济遗产、政治机构和治理创新的偶然相互作用形成了气候领导力的更加多样化的地理分布。认识到这些“不太可能”的气候先驱，可以重新定位地方治理学术，并将周边地区定位为加速净零转型的关键角色。
