Global climate change and intensified human activities drive rapid land use and land cover (LULC) changes, particularly in ecologically fragile regions like China's Southern Hilly Region (SHR), affecting ecosystem services (ESs) trade-offs/synergies. However, scale-dependent thresholds governing these relationships remain poorly quantified. We analyzed ESs dynamics (water yield, soil conservation, carbon storage, nutrient retention, habitat quality) across regional, watershed, and sub-watershed scales (1990–2020) using the InVEST model, sensitivity indices, and piecewise linear regression. ESs responses exhibited significant scale effects, with sub-watersheds showing the highest sensitivity to LULC changes and representing the most stable management unit. Particularly, we found that critical LULC thresholds regulate trade-offs/synergies: forest cover exceeding ∼70 % strongly enhanced synergies among multiple ESs, while cropland proportions between 30 and 65 % intensified trade-offs (e.g., between soil conservation and water yield). Impervious expansion consistently degraded ESs. Our results demonstrate that optimizing LULC patterns-prioritizing forest conservation (>70 % cover), limiting cropland (<65 %), and controlling urban sprawl-at the sub-watershed scale minimizes ESs trade-offs. This study establishes quantitative thresholds to guide targeted land-use planning and ecological restoration policies in hilly regions globally, supporting sustainable landscape governance.
全球气候变化和人类活动加剧推动了土地利用和土地覆盖(LULC)的快速变化,特别是在中国南部丘陵地区(SHR)等生态脆弱地区,影响了生态系统服务(ESs)的权衡/协同效应。然而,控制这些关系的依赖于规模的阈值仍然很难量化。利用InVEST模型、敏感性指数和分段线性回归分析了1990-2020年区域、流域和亚流域尺度上的生态环境动态(水量、土壤保持、碳储量、养分保持和生境质量)。生态系统响应表现出显著的尺度效应,其中小流域对LULC变化的敏感性最高,是最稳定的管理单元。特别是,我们发现临界LULC阈值调节着权衡/协同效应:森林覆盖率超过70%强烈增强了多个生态系统之间的协同效应,而农田比例在30%至65%之间则强化了权衡(例如,在水土保持和水量之间)。不透水膨胀持续降低ESs。我们的研究结果表明,在亚流域尺度上优化LULC模式——优先保护森林(70%覆盖率)、限制耕地(65%)和控制城市扩张——可以最大限度地减少碳排放的权衡。本研究建立了定量阈值,可指导全球丘陵区有针对性的土地利用规划和生态恢复政策,支持可持续的景观治理。

A novel watershed viability assessment grounded in global sustainable development goals 基于全球可持续发展目标的流域生存力评估
IF 5.6 Q1 ENVIRONMENTAL SCIENCES Pub Date : 2026-06-01 Epub Date: 2026-01-15 DOI: 10.1016/j.indic.2025.101057

The current study will deal with the problem of natural resource degradation, presenting a new, multifaceted approach to the measurement of watershed health. This idea determines the capacity of a watershed to be structurally and functionally sound within a safe operating interval that has its upper (i.e., resilience) and lower (i.e., release) limits. The method extends beyond the analogous concepts by quantitatively prognosing the nearness of a system to highly sensitive breaking points, by providing a dynamically diagnostic framework and management recommendations. The viability was determined at economic, social, infrastructural, and environmental dimensions. Content Validity Ratio (CVR) and Index (CVI) were used to validate criteria refinement with expert input (n = 40) used to refine criteria. A complex viability index was calculated on these criteria, and interrelationships between them investigated by Interpretive Structural Modelling (ISM) and MICMAC analysis. The framework was applied to the Shazand Watershed in Iran and determined a moderate-depletion state with a weighted mean index of viability of 41.46 % (±5.74). Spatial zoning map showed central sub-watersheds to be the most vulnerable. A SDGs-based performance evaluation revealed that SDG 13 (Climate Action) and SDG 3 (Good Health and Well-being) were the most successful (80.63 % and 62.59 %). On the other hand, the lowest scores were received by SDG 17 (Partnerships for the Goals) and SDG 15 (Life on Land) (30.71 % and 33.40 %). The conceptualized model and its pilot application demonstrates a critical and transferable instrument for assessing watershed viability that decision-makers should use to develop comprehensive and specific watershed management plans.
目前的研究将处理自然资源退化问题,提出一种新的、多方面的方法来衡量流域健康。这一理念决定了流域在安全运行区间内结构和功能健全的能力,该区间有其上限(即弹性)和下限(即释放)。该方法通过提供动态诊断框架和管理建议,定量预测系统与高度敏感断点的接近程度,从而超越了类似的概念。可行性是在经济、社会、基础设施和环境方面确定的。使用内容效度比(CVR)和指数(CVI)来验证标准的改进,使用专家输入(n = 40)来改进标准。在此基础上计算了复合生存力指数,并通过解释结构模型(ISM)和MICMAC分析研究了它们之间的相互关系。该框架应用于伊朗Shazand流域,确定其处于中度枯竭状态,加权平均生存指数为41.46%(±5.74)。空间分区图显示,中部分流域最脆弱。基于可持续发展目标的绩效评估显示,可持续发展目标13(气候行动)和可持续发展目标3(良好健康和福祉)最为成功(分别为80.63%和62.59%)。另一方面,得分最低的是可持续发展目标17(目标伙伴关系)和可持续发展目标15(陆地上的生命)(30.71%和33.40%)。概念化模型及其试点应用表明,这是评估流域生存能力的关键和可转移工具,决策者应利用它制定全面和具体的流域管理计划。

China and Africa in the green transition: Evidence from wavelet analysis 绿色转型中的中国和非洲:来自小波分析的证据
IF 5.6 Q1 ENVIRONMENTAL SCIENCES Pub Date : 2026-06-01 Epub Date: 2026-02-02 DOI: 10.1016/j.indic.2026.101154

This study analyzes the temporal synchronization and spillover impacts of China's green growth on African Regional Economic Communities (RECs) from 1996 to 2019, emphasizing emissions dynamics and environmental externalities. Two composite indicators are developed: the Stimulating Green Growth Index (SGGI), which measures advancements in energy sustainability, production efficiency, and social inclusion, and the Destimulating Green Growth Index (DGGI), which indicates pollution intensity, resource depletion, and ecological degradation. The indices are generated by a two-stage Principal Component Analysis and examined through the Continuous Wavelet Transform, facilitating the detection of time-frequency-specific synchronization and lead-lag correlations. The results indicate a significant disparity in the transfer of green growth between China and Africa. China's promotion of green growth has weak and sporadic alignment with African trends, demonstrating modest convergence solely following the Paris Agreement. Conversely, China's counterproductive green growth demonstrates robust, enduring, and China-driven synchronization with African regions, signifying considerable transboundary spillovers of environmental costs. Phases of accelerated economic growth in China often align with increasing destimulating pressures in resource-abundant African Regional Economic Communities, indicating emissions externalization via trade and extractive connections. This study documents pre-2020 dynamics to offer a baseline for assessing China's post-2020 dual-carbon promises and their effects on carbon spillovers within China–Africa supply chains.
本文分析了1996 - 2019年中国绿色增长对非洲区域经济共同体(RECs)的时间同步性和溢出效应,重点分析了排放动态和环境外部性。该报告提出了两个综合指标:刺激绿色增长指数(SGGI),衡量能源可持续性、生产效率和社会包容方面的进步;抑制刺激绿色增长指数(DGGI),衡量污染强度、资源枯竭和生态退化。指数由两阶段主成分分析生成,并通过连续小波变换进行检测,便于检测特定时频同步和超前滞后相关性。结果表明,中国和非洲在绿色增长转移方面存在显著差异。中国对绿色增长的推动与非洲发展趋势的一致性较弱且零星,仅在《巴黎协定》之后才显示出适度的趋同。相反,中国适得其反的绿色增长与非洲地区表现出强劲、持久和中国驱动的同步,这表明环境成本的跨境溢出效应相当大。中国经济加速增长的阶段往往与资源丰富的非洲区域经济共同体日益增长的刺激压力相一致,表明通过贸易和采掘联系实现了排放外部化。本研究记录了2020年前的动态,为评估中国2020年后的双碳承诺及其对中非供应链碳溢出效应的影响提供了基准。

Assessing sustainability indicators of carbon emissions in the Netherlands: The roles of innovation, renewable energy, and economic openness 评估荷兰碳排放的可持续性指标:创新、可再生能源和经济开放的作用
IF 5.6 Q1 ENVIRONMENTAL SCIENCES Pub Date : 2026-06-01 Epub Date: 2026-02-07 DOI: 10.1016/j.indic.2026.101167

This paper examines the long- and short-run relationships between innovation (INNO), carbon dioxide emissions (CO2), real economic activity (GDP), foreign direct investment (FDI), trade openness (TRAD), and renewable energy (RE) in the Netherlands over 1990–2023 using the autoregressive distributed lag (ARDL) bounds testing framework. We specify a log-linear emissions model and, as a robustness check, an INNO-driven model to study feedback effects. The empirical strategy includes unit-root testing (ADF/PP/KPSS), structural break screening, ARDL bounds cointegration tests, long-run estimation with an error-correction representation, and extensive diagnostics (serial correlation, heteroskedasticity, and functional form) as well as stability tests (CUSUM/CUSUMSQ). While INNO, RE penetration, and trade structure are conceptually expected to reduce emissions through efficiency and substitution channels, scale effects from GDP and FDI can increase emissions unless accompanied by sufficiently strong technological upgrading. The study contributes country-specific evidence for the Netherlands, a small open economy with advanced INNO capacity and ambitious climate targets. Results sections include carefully formatted tables and figures templates ready for estimation. Rather than identifying generic emissions drivers, this study evaluates the effectiveness and stability of innovation-led decarbonization under intensified post-2020 climate policy regimes in the Netherlands.
本文采用自回归分布滞后(ARDL)边界检验框架,考察了1990-2023年间荷兰创新(INNO)、二氧化碳排放(CO2)、实体经济活动(GDP)、外国直接投资(FDI)、贸易开放(TRAD)和可再生能源(RE)之间的长期和短期关系。我们指定了一个对数线性排放模型,并作为鲁棒性检查,一个innoo驱动的模型来研究反馈效应。实证策略包括单位根检验(ADF/PP/KPSS)、结构断裂筛选、ARDL界协整检验、带有纠错表示的长期估计、广泛的诊断(序列相关性、异方差性和功能形式)以及稳定性检验(CUSUM/CUSUMSQ)。虽然创新、可再生能源渗透率和贸易结构在概念上有望通过效率和替代渠道减少排放,但GDP和FDI的规模效应可能会增加排放,除非伴随着足够强大的技术升级。该研究为荷兰提供了具体国家的证据,荷兰是一个小型开放经济体,具有先进的创新能力和雄心勃勃的气候目标。结果部分包括精心格式化的表格和图形模板,以便进行估计。本研究没有确定一般的排放驱动因素,而是评估了荷兰在强化的2020年后气候政策制度下创新主导的脱碳的有效性和稳定性。

The Indo-Gangetic Plains (IGP) remain highly climate vulnerable, where farmers experience limited access to timely, trusted, and contextualized risk information necessary for adaptation. This study examines how exposure to risk communication, along with key socio-psychological determinants, shapes behavioural responses to climate change. Using the Stimulus-Organism-Response (S-O-R) framework, six constructs were conceptualized and validated—Risk Communication, Social Participation, Institutional Awareness, Risk Perception, Negative Emotions, and Behavioural Change. A multistage sampling approach was applied across Bihar and Uttar Pradesh, engaging 240 farmers. PLS-SEM was used to develop indicators, evaluate construct validity, and test structural relationships. Among the significant predictors, Negative Emotions strongly impacted Behavioural Change (β = 0.961), while Institutional Awareness significantly influenced both Negative Emotions (β = 0.817) and Risk Perception (β = 0.711). Beyond model fit, the validated indicators generated through this study can support future assessment of climate risk communication effectiveness and serve as reference metrics for extension and sustainability research. Overall, the study offers a contextually grounded and empirically strengthened risk communication model that can inform more responsive and farmer-centric advisory strategies to enhance climate resilience in the IGP. It provides valuable insights for designing more effective, psychologically informed risk communication strategies to strengthen climate resilience among vulnerable farming communities.
印度河-恒河平原(IGP)仍然极易受到气候变化的影响,农民获得适应气候变化所需的及时、可信和有背景的风险信息的渠道有限。本研究考察了暴露于风险沟通以及关键的社会心理决定因素如何影响对气候变化的行为反应。采用刺激-机体-反应(S-O-R)框架,对风险沟通、社会参与、制度意识、风险感知、负面情绪和行为改变这六个构念进行了概念化和验证。在比哈尔邦和北方邦采用了多阶段抽样方法,涉及240名农民。PLS-SEM用于制定指标、评估结构效度和检验结构关系。负性情绪显著影响行为改变(β = 0.961),制度意识显著影响负性情绪(β = 0.817)和风险感知(β = 0.711)。除了模型拟合之外,通过本研究生成的经过验证的指标可以支持未来气候风险沟通有效性的评估,并可作为推广和可持续性研究的参考指标。总体而言,该研究提供了一个基于背景和经验的风险沟通模型,可以为更具响应性和以农民为中心的咨询战略提供信息,以增强IGP的气候适应能力。它为设计更有效、心理知情的风险沟通策略,以加强脆弱农业社区的气候适应能力提供了宝贵的见解。

Cultural tourism as a driver for sustainable urban development in Hail City, Saudi Arabia 文化旅游作为沙特阿拉伯海尔城可持续城市发展的驱动力
IF 5.6 Q1 ENVIRONMENTAL SCIENCES Pub Date : 2026-06-01 Epub Date: 2026-01-23 DOI: 10.1016/j.indic.2026.101135

This study explores the potential of cultural tourism as a strategic driver for sustainable urban development in Hail City, Saudi Arabia, emphasizing its alignment with the objectives of Saudi Vision (2030). Situated at the intersection of heritage preservation, community participation, and environmental sustainability, the research investigates how Hail's rich cultural assets, ranging from the UNESCO-listed Jubbah Rock Art to its traditional urban fabric and crafts, can be transformed into engines of socio-economic growth. A qualitative-dominant mixed-methods approach was adopted, integrating document analysis, stakeholder interviews, field surveys, and comparative case studies from Fez, Kyoto, and Bath. Findings indicate that despite possessing significant cultural value, Hail's tourism potential remains underdeveloped due to infrastructural limitations and institutional fragmentation. Nevertheless, strong local identity, community enthusiasm, and ecological endowments provide a promising basis for sustainable transformation. The study proposes a comprehensive cultural tourism strategy structured around three interrelated pillars: infrastructure improvement, heritage preservation and programming, and community empowerment with environmental integration. The research contributes to global discourse on heritage-led urbanism by demonstrating how mid-sized cities in developing contexts can achieve balanced modernization, enhance quality of life, and preserve cultural authenticity through a locally adapted sustainability model.
本研究探讨了文化旅游作为沙特阿拉伯哈伊尔市可持续城市发展战略驱动力的潜力,强调了其与沙特愿景(2030)目标的一致性。位于遗产保护、社区参与和环境可持续性的交叉点,该研究调查了海尔丰富的文化资产,从联合国教科文组织列入的Jubbah岩石艺术到传统的城市结构和手工艺,如何转化为社会经济增长的引擎。采用了定性为主的混合方法,整合了文件分析、利益相关者访谈、实地调查和来自非斯、京都和巴斯的比较案例研究。研究结果表明,尽管具有重要的文化价值,但由于基础设施的限制和制度的碎片化,Hail的旅游潜力仍然不充分。然而,强烈的地方认同、社区热情和生态禀赋为可持续转型提供了有希望的基础。该研究提出了一个全面的文化旅游战略,该战略围绕三个相互关联的支柱:基础设施改善、遗产保护和规划、社区赋权与环境整合。该研究通过展示发展中的中等城市如何通过适应当地的可持续发展模式实现平衡的现代化、提高生活质量和保护文化真实性,为遗产主导的城市主义的全球话语做出了贡献。

The study proposes a comprehensive cultural tourism strategy structured around three interrelated pillars: infrastructure improvement, heritage preservation and programming, and community empowerment with environmental integration. The research contributes to global discourse on heritage-led urbanism by demonstrating how mid-sized cities in developing contexts can achieve balanced modernization, enhance quality of life, and preserve cultural authenticity through a locally adapted sustainability model.</div></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":"30 ","pages":"Article 101135"},"PeriodicalIF":5.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146081039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to climate change and human activities, the grasslands of the Qinghai-Xizang Plateau have experienced varying degrees of degradation, which has significantly reduced livelihoods of the herder households. Herders are indigenous to these vast grasslands. Over centuries, they have developed a strong sense of community belonging, which helps protect natural grasslands and prevent further degradation. This study explores how community belonging affects herders' willingness to restore degraded grasslands and examines the underlying mechanisms of this relationship. We frame our analysis within a common-pool resource framework to clarify the collective action dilemma associated with grassland restoration. The results indicate that community belonging shows a statistically significant and positive effect on herders’ willingness to restore degraded grasslands, suggesting a 36.7 % increase in willingness. Being a village cadre negatively moderates the impact of community belonging, indicating a 70.1 % decrease in the positive effect. Additionally, herders with smaller livestock scales, those who have access to loans, and those residing in the Haixi region exhibit stronger behavioral willingness responses to community belonging. Therefore, grassland restoration policies should focus on enhancing community belonging and leveraging social capital as a key component of grassland protection and restoration strategies, with targeted economic incentives and improved institutional trust through better policy implementation.
由于气候变化和人类活动的影响,青藏高原草原发生了不同程度的退化,严重影响了牧民的生计。牧民是这片广袤草原的原住民。几个世纪以来,他们已经形成了强烈的社区归属感,这有助于保护天然草原,防止进一步退化。本研究探讨了社区归属如何影响牧民恢复退化草原的意愿,并探讨了这种关系的潜在机制。我们在公共资源框架内进行分析,以澄清与草地恢复相关的集体行动困境。结果表明,群落归属对牧民恢复退化草原的意愿有显著的正向影响,增加了36.7%。村干部身份负向调节社区归属感的影响,表明正效应下降了70.1%。此外,牲畜规模较小的牧民、获得贷款的牧民和居住在海西地区的牧民对社区归属感表现出更强的行为意愿反应。因此,草原恢复政策应注重增强社区归属感和撬杠杆社会资本,将其作为草原保护与恢复战略的关键组成部分,通过更好的政策实施,有针对性地提供经济激励,提高制度信任。

Linking Bees, Biodiversity, and Breadwinners: Ecological and Economic values of Beekeeping for Agricultural productivity and livelihood sustainability in Southern Ethiopia 链接蜜蜂、生物多样性和养家糊口者:埃塞俄比亚南部养蜂对农业生产力和生计可持续性的生态和经济价值
IF 5.6 Q1 ENVIRONMENTAL SCIENCES Pub Date : 2026-06-01 Epub Date: 2026-02-02 DOI: 10.1016/j.indic.2026.101157

Linking Bees, Biodiversity, and Breadwinners highlights the complex and essential relationship between Bees and the survival of rural livelihoods. Although the role of bees in advancing sustainable development objectives is broadly recognized, a range of additional advantages offered by bees has not been completely acknowledged. This study examines how Beekeeping adoption influences ecological productivity and the sustainability of livelihoods for rural households across six kebele in Dilla Zuria, Wonago, and Dale woreda clusters in Southern Ethiopia. It employs a triangulated mixed-methods design that includes household surveys (n = 178), plot-level production data (n = 120), alongside 10 key informant interviews (KIIs) and 6 focus group discussions (FGDs). An index for livelihood sustainability (LSI) was developed utilizing normalized components of economic, social, and ecological factors. Findings indicate that adopting Beekeeping boosts the likelihood of enhanced livelihood sustainability by 6 percentage points, and every extra ETB 1000 in honey revenue elevates LSI by 1.2 percentage points. Productivity assessment shows that a one-unit rise in the pollinator index boosts crop yield by 12%, while adding 10 hives raises yield by 3%. Mediation analysis verifies a modest yet significant ecological pathway; adoption enhances pollinator abundance (β = 0.35, p < 0.001), leading to higher yield (β = 0.11, p = 0.007), resulting in a small but notable indirect benefit in LSI. Propensity score matching shows an average income increase of ETB 3200 for those who adopt. Qualitative evidence spines these conclusions, emphasizing Beekeeping as a means of income stability, ecosystem benefits, and empowerment, especially when combined with institutional backing and gender inclusivity. The research introduces and determines that Beekeeping acts as a connection between 3B's (Bees, Biodiversity, and Breadwinners) as preserving biodiversity and ensuring the sustainability of rural livelihoods. The research finds that enhancing Beekeeping in smallholder farming systems can greatly support in reaching the Sustainable Development Goals (SDGs)- especially SDG 1.1 and 1.2 through improved income-focused poverty alleviation, SDG 2 (Zero Hunger), SDG 13 (Climate Action), and SDG 15.1 and 15.5, aligning with the Biodiversity Strategy and Action Plan. Enhancing agroecological methods that support pollinators, increasing access to modern Beekeeping technologies, and boosting institutional capabilities can expedite advancements towards sustainable agri-food systems.
《联系蜜蜂、生物多样性和养家糊口者》强调了蜜蜂与农村生计生存之间复杂而重要的关系。虽然蜜蜂在促进可持续发展目标方面的作用已得到广泛承认,但蜜蜂提供的一系列额外优势尚未得到完全承认。本研究考察了在埃塞俄比亚南部的Dilla Zuria、Wonago和Dale worreda集群的六个kebele中,养蜂的采用如何影响农村家庭的生态生产力和生计的可持续性。该研究采用三角混合方法设计,包括住户调查(n = 178)、小区生产数据(n = 120)、10次关键信息者访谈(kii)和6次焦点小组讨论(fgd)。利用经济、社会和生态因素的标准化成分,开发了生计可持续性指数(LSI)。研究结果表明,养蜂使生计可持续性提高了6个百分点,蜂蜜收入每增加1000英镑,LSI就会提高1.2个百分点。生产力评估显示,传粉者指数每增加一个单位,作物产量就会提高12%,而增加10个蜂箱,产量就会提高3%。中介分析验证了一条适度但重要的生态路径;采食增加传粉媒介丰度(β = 0.35, p < 0.001),导致更高的产量(β = 0.11, p = 0.007),在大规模种植中产生了虽小但显著的间接效益。倾向得分匹配显示,那些采用的人平均收入增加了3200英镑。定性证据支持这些结论,强调养蜂是收入稳定、生态系统效益和赋权的一种手段,特别是在与制度支持和性别包容性相结合的情况下。该研究介绍并确定了养蜂作为3B(蜜蜂、生物多样性和养家糊口者)之间的联系,以保护生物多样性和确保农村生计的可持续性。研究发现,通过加强以收入为重点的扶贫、可持续发展目标2(零饥饿)、可持续发展目标13(气候行动)以及可持续发展目标15.1和15.5,加强小农农业系统的养蜂可以极大地支持实现可持续发展目标(SDG),特别是可持续发展目标1.1和1.2,并与《生物多样性战略和行动计划》保持一致。加强支持传粉媒介的农业生态方法,增加获得现代养蜂技术的机会,并提高机构能力,可以加快实现可持续农业粮食系统的进程。

Spatial differences in vegetation damage under typhoon hazards: A case study of a coastal urban district 台风灾害下植被破坏的空间差异——以滨海城区为例
IF 5.6 Q1 ENVIRONMENTAL SCIENCES Pub Date : 2026-06-01 Epub Date: 2026-01-26 DOI: 10.1016/j.indic.2026.101143

Coastal urban ecosystems are becoming increasingly vulnerable to climate-induced disturbance and damage due to the escalating frequency and intensity of typhoons. This study employed an integrated approach of remote sensing analysis and ground-based surveys to systematically assess the damage patterns and spatial heterogeneity of urban vegetation in the Jiangdong New District (Haikou, China) following super typhoon events. The results indicate that tree community diversity, measured by the Shannon index, was significantly and positively correlated with vegetation damage severity (p < 0.001, r = 0.496). Green space patch characteristics were positively associated with the extent of storm damage. In contrast, building height and landscape aggregation index showed negative correlations with damage severity. Approximately 56.4 % of the vegetated areas exhibited a declining trend in the normalized difference vegetation index (NDVI). Human activity intensity and the magnitude of vegetation decrease were significantly positively correlated in northeastern wetlands and negatively correlated in the southeastern tree nurseries. Relying solely on wind-resistant tree species is insufficient to develop a resilient ecosystem. Instead, heterogeneity in community structure and urban spatial layout are critical in increasing tree resistance to wind disturbances. These findings emphasize the need to consider landscape characteristics and human activity patterns along urban environmental when developing adaptation strategies for coastal cities to improve the resilience of urban green infrastructure to extreme climate events.
由于台风的频率和强度不断上升,沿海城市生态系统越来越容易受到气候引起的干扰和破坏。采用遥感分析与地面调查相结合的方法,系统评价了海口市江东新区超强台风过后城市植被的破坏格局和空间异质性。结果表明,以Shannon指数衡量的树木群落多样性与植被破坏程度呈显著正相关(p < 0.001, r = 0.496)。绿地斑块特征与风暴破坏程度呈正相关。建筑高度和景观聚集指数与破坏程度呈负相关。归一化植被指数(NDVI)呈下降趋势的植被面积约占56.4%。人类活动强度与植被减少幅度在东北湿地呈显著正相关,在东南部乔木苗圃呈显著负相关。仅仅依靠抗风树种不足以发展一个有弹性的生态系统。相反,群落结构和城市空间布局的异质性对于增强树木对风干扰的抵抗力至关重要。这些发现强调,在制定沿海城市适应战略时,需要考虑景观特征和城市环境中的人类活动模式,以提高城市绿色基础设施对极端气候事件的抵御能力。

The power of a biocentric view: Ecological worldviews as a key driver of subjective well-being for residents near nature reserves 生物中心观的力量:生态世界观是自然保护区附近居民主观幸福感的关键驱动因素
IF 5.6 Q1 ENVIRONMENTAL SCIENCES Pub Date : 2026-06-01 Epub Date: 2026-01-27 DOI: 10.1016/j.indic.2026.101148

Enhancing subjective well-being (SWB) is central to sustainable development, yet the psychological mechanisms linking ecological worldviews to SWB in conservation contexts remain underexplored. This study investigates how the New Ecological Paradigm (NEP)—a measure of biocentric worldview—shapes residents’ perceptions of ecosystem services (ES) and influences SWB in Dailing Town, a community adjacent to Liangshui National Nature Reserve in China. Using a mixed-methods approach combining Structural Equation Modeling (SEM) and Canonical Correspondence Analysis (CCA) with survey data from 169 residents, we find that: (1) SWB is highest in the health dimension but lowest in social relations, with specific deficits in transportation, water quality, and employment conditions; (2) NEP is the strongest predictor of SWB, exerting both direct effects and indirect effects mediated by enhanced ES perceptions; (3) ES preferences are segmented by socioeconomic and demographic factors: older, land-dependent residents prioritize cultural services (e.g., recreation, aesthetics), whereas younger, non-land-based residents value tangible provisioning and regulating services. These findings underscore the critical role of ecological worldviews in shaping well-being and highlight the need for targeted policies that integrate ecological education, social infrastructure, and differentiated livelihood strategies to foster synergistic human-nature outcomes in protected area communities.
增强主观幸福感(SWB)是可持续发展的核心,但在保护背景下,将生态世界观与主观幸福感联系起来的心理机制仍未得到充分探讨。本研究探讨了新生态范式(NEP)——一种衡量生物中心世界观的方法——如何塑造居民对生态系统服务(ES)的看法,并影响中国凉水国家级自然保护区附近的戴岭镇社区的SWB。采用结构方程模型(SEM)和典型对应分析(CCA)相结合的混合方法对169名居民的调查数据进行分析,发现:(1)主观幸福感在健康维度上最高,而在社会关系维度上最低,具体在交通、水质和就业条件方面存在缺陷;(2) NEP是主观幸福感最强的预测因子,在主观幸福感增强的介导下,NEP会产生直接效应和间接效应;(3)社会经济和人口因素对社会服务偏好进行了细分:年龄较大、依赖土地的居民优先考虑文化服务(如娱乐、美学),而年龄较小、不依赖土地的居民则重视有形的提供和调节服务。这些发现强调了生态世界观在塑造福祉方面的关键作用,并强调了有针对性的政策的必要性,这些政策将生态教育、社会基础设施和差异化的生计战略结合起来,以促进保护区社区的人与自然协同成果。
