Constructing resilient ecological networks (ENs) and identifying critical ecological spaces are essential for sustainable development. However, existing research on the robustness of nodes and corridors within ENs is often limited to a single perspective and lacks multidimensional analysis grounded in realistic scenarios. This limitation hinders accurate estimation of the threshold at which external shocks compromise overall network performance. In this study, we established a comprehensive EN resilience assessment framework for analyzing network resilience and identifying the key influences of specific ecological spaces from five dimensions: connectivity, integration, stability, transmissibility, and diversity. We found that the network exhibited strong structural resilience, reflected in high integration (1.00), connectivity (9.07), and stability (0.77); however, its functional resilience remained constrained by weak transmissibility (0.31) and an insufficient corridor buffer. Single and successive component failure simulations demonstrate that network resilience decreases nonlinearly and abruptly when critical elements are disrupted. We further identified the top 15 % of ecological sources and 35 % of ecological corridors as primary ecological spaces, which were concentrated in southeastern Gansu, southwestern Ordos, and the northern ecological demonstration zone of Shaanxi Province. Damaging these areas can trigger cascading effects, disrupting 158 biological migration pathways and causing a >50 % decrease in ecological resilience, ultimately pushing overall ecological resilience below the critical threshold, as they play a crucial role in maintaining the structural and functional integrity of ecosystems. These findings elucidate the influence of specific ecological components on overall network resilience, yielding valuable insights for guiding targeted ecological conservation and restoration strategies.

构建弹性生态网络和识别关键生态空间对于可持续发展至关重要。然而，现有的关于网络中节点和廊道鲁棒性的研究往往局限于单一视角，缺乏基于现实场景的多维分析。这种限制阻碍了对外部冲击影响整体网络性能的阈值的准确估计。本文从连通性、整合性、稳定性、可传递性和多样性五个维度构建了网络弹性综合评价框架，分析了网络弹性，并确定了特定生态空间的关键影响因素。研究发现，该网络表现出较强的结构弹性，体现在高整合（1.00）、高连通性（9.07）和高稳定性（0.77）；然而，其功能恢复能力仍然受到弱传递性（0.31）和走廊缓冲不足的限制。单部件故障和连续部件故障仿真表明，当关键部件发生故障时，网络恢复能力呈非线性突然下降。进一步确定了前15%的生态源和35%的生态廊道为一级生态空间，主要集中在甘肃东南部、鄂尔多斯西南部和陕西北部生态示范区。破坏这些区域会引发级联效应，破坏158个生物迁移途径，导致生态恢复力降低50%，最终将整体生态恢复力推至临界阈值以下，因为它们在维持生态系统的结构和功能完整性方面发挥着关键作用。这些发现阐明了特定生态成分对整体网络弹性的影响，为指导有针对性的生态保护和恢复策略提供了有价值的见解。

Urban parks serve multiple purposes for both residents and visitors. However, most existing research relies on small-scale surveys or questionnaires, which cannot fully capture how these two groups use parks differently across space and time. This study addresses that gap by using large-scale mobile phone signaling data to examine how residents and tourists visit urban parks in Chongqing, China, and what drives those patterns. We first use spatial analysis to identify the spatiotemporal characteristics of park visitation. We then apply multiscale geographically weighted regression (MGWR) to assess the influence of park attributes, transit access, built environments, and social media exposure. The results show clear contrasts between the two groups. Residents tend to visit nearby parks frequently, especially on weekends, while tourists concentrate on a small number of highly “internet-famous” parks during holidays. Residents' visitation is shaped mainly by park accessibility and attributes, whereas tourists’ visitation is more strongly linked to social media visibility. In addition, the effects of factors such as distance to metro or bus stops and park size vary across locations for both groups. These findings underscore the importance of considering differences between user groups when planning and managing urban parks.

城市公园对居民和游客都有多种用途。然而，大多数现有的研究都依赖于小规模的调查或问卷调查，这并不能完全捕捉到这两个群体在空间和时间上对公园的不同使用。本研究通过使用大规模移动电话信号数据来研究重庆居民和游客如何访问城市公园，以及是什么驱动了这些模式，从而解决了这一差距。本文首先利用空间分析方法对公园游客的时空特征进行了识别。然后，我们应用多尺度地理加权回归（MGWR）来评估公园属性、交通通道、建筑环境和社交媒体曝光的影响。结果显示出两组人之间的明显差异。当地居民倾向于频繁访问附近的公园，尤其是在周末，而游客则在假期集中在少数“网红”公园。居民的访问量主要受公园可达性和属性的影响，而游客的访问量与社交媒体知名度的关系更强。此外，对于这两组人来说，距离地铁或公交车站的距离以及公园的大小等因素的影响在不同的地点也有所不同。这些发现强调了在规划和管理城市公园时考虑用户群体差异的重要性。

Exploring the dynamic evolution of the Cultivated Land Green Use System (CLGUS) is essential for advancing relationships between humans and nature and promoting agricultural sustainability. Based on complex adaptive system and adaptive cycle theories, this study constructs an analytical framework to investigate the spatio-temporal patterns, evolutionary stages, and driving mechanisms of the adaptive cycle evolution in China's CLGUS from 2000 to 2022, using spatial regression and nonlinear methods. Differentiated zoning strategies are further proposed. The results indicate that: (1) The adaptive cycle level of CLGUS in China increased steadily from 0.428 to 0.606, exhibiting temporal evolution patterns and spatial differentiation characteristics. Temporally, it alternated between “steady accumulation” and “stage-leap” phases, while spatially it displayed three-dimensional spatial dislocation and agglomeration trends. (2) The adaptive cycle evolution of CLGUS in China exhibited stage characteristics of dynamic transformation and spatial embedding. Cities in transitional stages, such as r-K and K-Ω, tended to cluster around regions in preceding stages, like r and K. (3) Driving factors showed significant spatio-temporal non-stationarity and nonlinear threshold effects. Relief amplitude, GDP per capita, and urbanization rate exhibited inverted U-shaped relationships with the adaptive cycle level, with critical thresholds shifting dynamically. (4) Based on key factor thresholds, four cultivated land green use zones were delineated: steady-state optimization zone, collaborative regulation zone, targeted breakthrough zone, and system enhancement zone. These findings provide decision-making references for establishing new regional frameworks for cultivated land protection and achieving sustainable use of cultivated land.

研究耕地绿色利用系统（CLGUS）的动态演变，对于推进人与自然关系、促进农业可持续发展具有重要意义。基于复杂适应系统和适应周期理论，运用空间回归和非线性方法，构建了2000 - 2022年中国CLGUS适应周期演化的时空格局、演化阶段和驱动机制分析框架。进一步提出差异化分区策略。结果表明：(1)中国CLGUS的适应周期水平从0.428稳步上升至0.606，呈现出时间演化格局和空间分异特征。在时间上表现为“稳定积累”和“阶段性飞跃”交替，在空间上表现为三维空间错位和集聚趋势。(2)中国CLGUS自适应周期演化表现出动态转换和空间嵌入的阶段性特征。处于过渡阶段的城市（r-K和K-Ω）倾向于围绕r和K等前阶段的区域聚集。(3)驱动因素表现出显著的时空非平稳性和非线性阈值效应。起伏幅度、人均GDP和城市化率与适应周期水平呈倒u型关系，临界阈值动态移动。(4)基于关键因子阈值，划分了4个耕地绿色利用区：稳态优化区、协同调控区、定向突破区和系统增强区。研究结果为建立新的区域耕地保护框架，实现耕地可持续利用提供了决策参考。

Social vulnerability to flooding is shaped by intersectional social marginalization, yet most quantitative assessments employ indicators of single populations. This study applies spatial machine learning to examine how the intersectional social vulnerability indicators of poverty-race, poverty-housing tenure, and race-housing tenure compare with traditional discrete indicators of single populations in predicting flood exposure in California. Using geographically weighted random forests and partial dependence plots, we model spatial heterogeneity and non-linear relationships between social vulnerability and exposure. We quantified flood exposure using a population-adjusted measure derived from building footprints and modeled 500-year fluvial and pluvial flood hazard. The results reveal distinct explanatory power of discrete and intersectional indicators. Variable importance analysis shows that intersectional indicators, such as Poor Renters and Non-white Renters, have stronger predictive importance than their discrete counterparts, particularly in urban regions, with mean local IncMSE values of 15.6–16.9 % compared to 12.3–14.8 %. Partial dependence analysis revealed threshold effects of non-linear indicator influence, with predicted exposure increasing sharply once intersectional populations exceed ∼60 % of tract-level representation. Our findings highlight limitations of assuming uniform indicator effects, and the need for non-linear, spatially adaptive models that increase conceptual alignment between social vulnerability theory and indicator modeling by integrating intersectional dimensions.

社会对洪水的脆弱性是由交叉社会边缘化形成的，但大多数定量评估采用单一人口的指标。本研究应用空间机器学习研究了贫困-种族、贫困住房使用权和种族-住房使用权的交叉社会脆弱性指标与传统的单一人口离散指标在预测加州洪水暴露方面的比较。利用地理加权随机森林和部分依赖图，我们模拟了社会脆弱性与暴露之间的空间异质性和非线性关系。我们使用从建筑足迹中得出的人口调整措施来量化洪水暴露，并模拟了500年的河流和洪水灾害。结果显示离散指标和交叉指标具有明显的解释力。变量重要性分析表明，交叉性指标，如贫困租房者和非白人租房者，比其离散对应指标具有更强的预测重要性，特别是在城市地区，平均当地IncMSE值为15.6 - 16.9%，而12.3 - 14.8%。部分依赖分析揭示了非线性指标影响的阈值效应，一旦交叉种群超过60%的区域水平代表性，预测的暴露量就会急剧增加。我们的研究结果强调了假设统一指标效应的局限性，以及对非线性、空间适应性模型的需求，这些模型通过整合交叉维度来增加社会脆弱性理论和指标模型之间的概念一致性。

Ensuring equal access to urban parks is vital for sustainable city development. However, prevailing assessment of park accessibility, which mainly rely on spatial proximity, offer a limited perspective by overlooking destination appeal and journey quality. Utilizing social media and street view images, this study proposes a novel multimodal framework that advanced the evaluation of park accessibility from spatial proximity to experiential quality. The framework first integrated online public feedback and offline facility quality using the PCA-AHP-TOPSIS method to evaluate park attractiveness. Then a greenery-perceived distance was proposed by integrating street-level visual greenness and travel distance across three modes to model the perceived impedance of journeys. The effectiveness of the proposed framework is tested in the main area of Wuhan, China. The results reveal that the proposed attraction coefficient correlates more strongly with actual park usage (R² = 0.68) than area-based metrics (R² = 0.41). Incorporating GVI significantly improves the explanatory power for visitation frequency, particularly for walking (R² increase from 0.45 to 0.50) and cycling (from 0.44 to 0.48). GVI's influence varies across travel modes: within a 30-min threshold, walking visitation shows a strong positive correlation with GVI while being weakly affected by distance, whereas distance remains the dominant deterrent for cycling and driving. A pronounced spatial disparity is identified, with 45.3 % of walking zones lacking park access within 30 min, highlighting a mismatch between accessibility and population density. This framework provides practical tools for urban planning and public health, contributing meaningfully to the long-term sustainable development of cities.

确保平等进入城市公园对城市可持续发展至关重要。然而，目前对公园可达性的评估主要依赖于空间接近性，忽视了目的地的吸引力和旅行质量，提供了有限的视角。利用社交媒体和街景图像，本研究提出了一个新的多模式框架，将公园可达性的评价从空间接近性提升到体验质量。该框架首先使用PCA-AHP-TOPSIS方法综合了在线公众反馈和离线设施质量来评估公园吸引力。在此基础上，结合三种模式下的街道视觉绿化度和出行距离，提出了一种绿色感知距离模型来模拟出行感知阻抗。该框架的有效性在中国武汉的主要地区进行了测试。结果表明，建议的吸引力系数与公园实际使用的相关性更强（R2 = 0.68），而不是基于区域的指标（R2 = 0.41）。纳入GVI显著提高了访问频率的解释力，尤其是步行（R2从0.45增加到0.50）和骑行（R2从0.44增加到0.48）。不同出行方式对GVI的影响存在差异：在30分钟阈值内，步行访问量与GVI呈强正相关，距离对GVI的影响较弱，而距离仍然是骑行和驾车的主要阻碍因素。研究还发现了明显的空间差异，45.3%的步行区在30分钟内没有公园通道，凸显了可达性与人口密度之间的不匹配。这一框架为城市规划和公共卫生提供了实用工具，对城市的长期可持续发展作出了有意义的贡献。

As technological progress reshapes the skill demands of regional labor markets, developing countries often exhibit pronounced income inequality. However, existing research on skill-biased technological change (SBTC) primarily focuses on its impact on labor forces with varying skill levels, paying insufficient attention to its role in urban-rural income inequality (URII). This study employs machine learning models to estimate the level of SBTC across 246 prefecture-level cities in China from 2005 to 2015 and analyzes its effect on URII. The results show that China's SBTC intensity increased significantly during the study period, with every 1 % rise in SBTC widening the URII by 0.108 %. This effect remains robust across multiple robustness tests. Furthermore, the widening effect is particularly pronounced in regions with higher foreign direct investment, urbanization level, and non resource-dependent cities. Finally, we find that task biased technological change further amplifies the positive impact of SBTC on URII. Our findings provide policy implications for refining urban-rural development strategies to enhance the inclusivity of technological progress and facilitate skill upgrading among rural laborers.

随着技术进步重塑区域劳动力市场的技能需求，发展中国家往往表现出明显的收入不平等。然而，现有关于技能偏倚技术变革（SBTC）的研究主要集中在其对不同技能水平劳动力的影响上，而对其在城乡收入不平等（URII）中的作用关注不足。本研究采用机器学习模型估算了2005 - 2015年中国246个地级市的SBTC水平，并分析了其对URII的影响。结果表明，研究期间，中国的SBTC强度显著增加，每增加1%，uri就会扩大0.108%。这种效应在多个稳健性测试中保持稳健性。此外，在外国直接投资、城市化水平和非资源依赖型城市较高的地区，这种扩大效应尤为明显。最后，我们发现任务偏向的技术变革进一步放大了SBTC对URII的积极影响。研究结果为完善城乡发展战略以增强技术进步的包容性和促进农村劳动力技能升级提供了政策启示。

This paper presents a case study of a climate-focussed digital internship pilot program intent on increasing engagement with, and jobs in, the “Bluetech” ocean-based economy in Baltimore, Maryland. Understanding participants' lived experiences across multiple strands of alignment–including general interest, digital skills and technology access, environmental knowledge, and perceptions of climate and environmental problems–supported their engagement in the program and advanced their educational and workforce goals. Those experiences are undergirded by the historical setting of Baltimore, which is navigating contemporary interrelated impacts of global change due to climate, economic, and digital infrastructure transformations. Like many cities, Baltimore has developed a policy agenda focused on technological innovation, sustainability, and education as conduits of progress meant to address these concerns. However, the promise of innovation across these policy areas may not be realized if Baltimore's youth do not attain the necessary digital competencies and relevant knowledge to address them. An iterative pedagogy was applied in order to help interns gain conceptual depth, technical skills, and content knowledge, and yielded insights about how youth may traverse the complexities of the modern Bluetech economy. Baltimore's innovation-forward policy agenda continues to require technology, education access and opportunity to connect to the economic directions being designed. And yet, the same advancement of innovation may also exacerbate the longstanding poverty present in the city if more is not done to bridge everyday experiences of youth with opportunities to learn and engage in foundational experiences, skills and knowledge upon which innovation will be based.

本文介绍了一个以气候为重点的数字实习试点项目的案例研究，该项目旨在增加与马里兰州巴尔的摩市“蓝色科技”海洋经济的接触和就业机会。了解参与者在多个方面的生活经历，包括一般兴趣、数字技能和技术获取、环境知识以及对气候和环境问题的看法，有助于他们参与项目，并推进他们的教育和劳动力目标。巴尔的摩的历史背景为这些经验提供了基础，该城市正在应对气候、经济和数字基础设施转型带来的全球变化的当代相互关联的影响。像许多城市一样，巴尔的摩制定了一项政策议程，重点关注技术创新、可持续性和教育，作为解决这些问题的进步渠道。然而，如果巴尔的摩的年轻人没有获得必要的数字能力和相关知识来解决这些问题，那么这些政策领域的创新承诺可能无法实现。为了帮助实习生获得概念深度、技术技能和内容知识，采用了迭代教学法，并就年轻人如何穿越现代蓝科技经济的复杂性产生了见解。巴尔的摩的创新政策议程继续需要技术、教育和机会来连接正在设计的经济方向。然而，如果不采取更多措施，将年轻人的日常经历与学习和参与创新所基于的基础经验、技能和知识的机会联系起来，那么创新的进步也可能加剧城市中长期存在的贫困。

Despite the emerging role of environmental firms (EFs) in driving urban green transitions, the capacity of cities to develop EFs varies significantly. A profound understanding of EFs locations is required for more cities to benefit from the development of EFs. This paper proposes a new analytical framework that decomposes the location into two components: the local conditions of cities and their locational attractiveness compared to other cities. The framework incorporates the Lotka-Volterra model and Dendrinos-Sonis models to identify local conditions and locational attractiveness, respectively, from a co-evolved perspective. The development of EFs in the Yangtze River Delta (YRD) of China during 2000–2022 serves as a case. The empirical findings have identified five types of locations: glocalized, local-to-global, localized, footloose, and peripheral. Most cities in YRD can offer localized locations for EFs due to the abundance of industrial assets and natural assets and the absence of environmental infrastructures. Fewer than half of the cities can offer an inter-city interaction location based on benefits derived from knowledge creation and technological legitimation and drawbacks experienced in market formation and investment mobilization. The glocalized location for anchoring external resources and collaborating with external actors has an amplification effect on EF's development, while the local-to-global location for exploring external emerging market does not. Overall, this new typology of locations goes beyond the conventional core-periphery structure of an urban agglomeration, and provides a more nuanced spatial framework for the spatial planning of emerging industries.

尽管环境企业在推动城市绿色转型方面的作用越来越大，但城市发展环境企业的能力差异很大。要使更多的城市受益于电子商务的发展，需要对电子商务的位置有深刻的了解。本文提出了一种新的分析框架，将区位因素分解为两部分：城市的本地条件和相对于其他城市的区位吸引力。该框架结合了Lotka-Volterra模型和Dendrinos-Sonis模型，分别从共同进化的角度确定当地条件和地点吸引力。2000年至2022年中国长三角地区的生态系统发展就是一个例子。实证研究结果确定了五种类型的位置：全球定位、本地到全球、本地化、自由流动和外围。由于工业资产和自然资产丰富，而环境基础设施缺乏，长三角的大多数城市都可以提供本地化的电子商务地点。根据知识创造和技术合法化带来的好处以及市场形成和投资动员方面的缺陷，只有不到一半的城市能够提供城际互动地点。锚定外部资源和与外部行动者合作的全球定位对EF的发展具有放大效应，而探索外部新兴市场的从本地到全球定位则没有放大效应。总体而言，这种新的区位类型超越了传统的城市群核心-外围结构，并为新兴产业的空间规划提供了更细致入微的空间框架。
