Insects represent the largest component of global biodiversity, and widespread declines in their richness and abundance have raised concerns about ecosystem functioning. Yet insect communities in natural and semi-natural grasslands, and the drivers of their recent changes, remain poorly studied at broad spatial scales. In Illinois (USA), efforts to preserve and restore native tallgrass prairies have been ongoing for decades, but their impact on native insect communities remain poorly understood. We conducted a statewide assessment of Auchenorrhyncha communities (Hemiptera, hereafter ‘hoppers’) along a gradient of anthropogenic disturbance. By sampling both plants and hoppers across prairie habitats, we evaluated how management practices and habitat history influence hopper communities through direct and indirect (trophic) pathways. Using community-level analyses and structural equation modeling, we tested hypotheses regarding direct and indirect effects of management intensity, habitat type, and environmental factors on plant and hopper communities. Responses were assessed for prairie-dependent species (e.g., Flexamia grammica and Calamovilfa longifolia), overall species richness (plants and hoppers), and habitat quality indices (Floristic Quality Index, Auchenorrhyncha Quality Index [AQI]). Higher management intensity indirectly promotes hopper species richness through enhanced plant species richness. However, this pattern did not extend to the AQI, which declined significantly under high-intensity management in hill prairies, which currently serve as refuges for the remaining prairie specialist hoppers. These findings suggest that while prairie management benefits plant diversity, its effects on prairie-dependent insect communities are more complex and mediated by ecological and historical factors. Effective conservation of hopper communities may therefore require targeted, habitat-specific management strategies.
昆虫是全球生物多样性的最大组成部分,其丰富度和丰度的普遍下降引起了人们对生态系统功能的担忧。然而,在广泛的空间尺度上,对自然和半自然草地上的昆虫群落及其近期变化的驱动因素的研究仍然很少。在美国伊利诺斯州,保护和恢复本土高草草原的努力已经进行了几十年,但它们对本土昆虫群落的影响仍然知之甚少。我们沿着人为干扰的梯度对全州范围内的Auchenorrhyncha群落(半翅目,以下简称“跳虫”)进行了评估。通过对草原生境的植物和跳虫进行采样,我们评估了管理实践和生境历史如何通过直接和间接(营养)途径影响跳虫群落。利用群落水平分析和结构方程模型,验证了管理强度、生境类型和环境因子对植物和飞蛾群落的直接和间接影响。评估了草原依赖物种(如Flexamia grammica和Calamovilfa longifolia)、总体物种丰富度(植物和跳蝇)和生境质量指数(Floristic quality Index, Auchenorrhyncha quality Index [AQI])的响应。较高的管理强度通过提高植物物种丰富度间接促进了飞蛾物种丰富度。然而,这种模式并没有延伸到AQI,在高强度管理下,AQI显著下降,目前这些草原是剩余草原专科跳鸟的避难所。这些发现表明,虽然草原管理有利于植物多样性,但其对草原依赖昆虫群落的影响更为复杂,并受到生态和历史因素的调节。因此,有效保护跳虫群落可能需要有针对性的、针对栖息地的管理策略。

The global call for expanding protected areas to conserve biodiversity often conflicts with the livelihoods of the local communities inhabiting these regions. Understanding these communities’ perspectives is crucial for balancing conservation efforts with their well-being. This study surveyed the local communities living near Kubah National Park to explore their perceived benefits and concerns regarding the park’s existence. Using the best-worst scaling approach, we found that the diversity of flora and fauna was ranked as the most beneficial aspect of the park, whereas restriction of resource access was identified as the most significant concern. Additionally, latent class analysis revealed substantial heterogeneity in preferences among the respondents. These findings offer important insights for policymakers aiming to expand protected areas while addressing the needs of adjacent communities.
扩大保护区以保护生物多样性的全球呼吁往往与居住在这些地区的当地社区的生计相冲突。了解这些社区的观点对于平衡保护工作和他们的福祉至关重要。本研究调查了居住在库巴国家公园附近的当地社区,以探讨他们对公园存在的感知利益和担忧。使用最佳-最差尺度方法,我们发现动植物多样性被列为公园最有益的方面,而资源获取限制被确定为最重要的问题。此外,潜在类别分析揭示了受访者偏好的实质性异质性。这些发现为决策者在扩大保护区的同时解决邻近社区的需求提供了重要的见解。

Geodiversity provides the abiotic foundation that shapes ecosystems and supports biodiversity. However, its role in conservation planning remains underrepresented. This study investigates spatial overlaps and functional linkages between potential Key Geoheritage Areas (KGAs) and Key Biodiversity Areas (KBAs) in Spain and Scotland, aiming to promote a more integrated conservation framework. Using national geosite inventories and the World Database of KBAs, we conducted spatial analyses and inferred ecological dependencies based on geological features and habitat data.
In Spain, 78% of the surface area of potential KGAs lies entirely within KBAs, despite KGAs covering only 1.7% of the total KBA area. These KGAs include volcanic, karstic, coastal, and tectonic systems that underpin habitats for protected species. In Scotland, all 40 globally important KBAs show inferred functional links to geoheritage, particularly through coastal geomorphology, soils, and hydrological systems supporting seabird and wetland species.
The results demonstrate that co-located KGAs and KBAs offer opportunities for integrated management, enhancing conservation effectiveness by recognizing the interdependence of abiotic and biotic systems. This innovative framework supports holistic conservation strategies, especially under climate change and land-use pressures. The study highlights the need for interdisciplinary approaches and skilled practitioners capable of managing both biodiversity and geoheritage within protected areas.
地质多样性为形成生态系统和支持生物多样性提供了非生物基础。然而,它在保护规划中的作用仍然没有得到充分的体现。本研究探讨了西班牙和苏格兰潜在的关键地质遗产区(KGAs)和关键生物多样性区(KBAs)之间的空间重叠和功能联系,旨在促进更综合的保护框架。利用国家地质遗址清查和世界地质bas数据库,我们进行了空间分析,并根据地质特征和栖息地数据推断出生态依赖关系。在西班牙,尽管KGAs仅占KBA总面积的1.7%,但潜在KGAs表面积的78%完全位于KBA内。这些KGAs包括支撑受保护物种栖息地的火山、岩溶、海岸和构造系统。在苏格兰,所有40个全球重要的kba都显示出与地质遗产的推断功能联系,特别是通过支持海鸟和湿地物种的沿海地貌、土壤和水文系统。结果表明,通过认识到非生物系统和生物系统的相互依存关系,共同定位的KGAs和KBAs为综合管理提供了机会,提高了保护效果。这一创新框架支持整体保护战略,特别是在气候变化和土地利用压力下。这项研究强调需要跨学科的方法和熟练的实践者来管理保护区内的生物多样性和地质遗产。

Protected Natural Areas (PNA) are a primary tool for conserving biodiversity and are used internationally. However, there is currently no decree ensuring their proper functioning, especially considering the rapid expansion of human activities. In Mexico, 182 PNA have been decreed, of which 125 terrestrial areas were analyzed to assess fragmentation and connectivity using land cover data from the MAD-Mex system (Monitoring Activity Data for the Mexican REDD + program) and a least-cost path modeling approach. A cluster analysis based on fragmentation metrics resulted in the formation of three groups of PNA, which were classified through discriminant analysis into low, medium, and high vulnerability levels. Subsequently, the extreme groups (low and high vulnerability) were characterized using nine socioeconomic variables, through a generalized linear model. The most vulnerable PNA are concentrated in the central region of the country, where population density, mining activity, and proximity to metropolitan areas increase fragmentation and reduce connectivity. A generalized linear model showed that the vulnerability of PNA increases with human population density and the presence of mines, while it decreases with distance to metropolitan areas and the presence of tourist areas. This analysis provides important insights into the local threats faced by each of Mexico’s terrestrial PNA. Such information is crucial for improving management plans and conservation strategies tailored to the specific threats confronting these areas.
自然保护区(PNA)是保护生物多样性的主要工具,在国际上得到广泛使用。但是,目前没有法令确保其适当运作,特别是考虑到人类活动的迅速扩大。在墨西哥,已经颁布了182个PNA,使用MAD-Mex系统(墨西哥REDD +计划的监测活动数据)的土地覆盖数据和最低成本路径建模方法,分析了其中125个陆地区域,以评估碎片化和连通性。基于碎片化指标的聚类分析将PNA划分为三组,并通过判别分析将其分为低、中、高脆弱性。随后,通过广义线性模型,利用9个社会经济变量对极端群体(低脆弱性和高脆弱性)进行了表征。最脆弱的PNA集中在该国的中部地区,那里的人口密度、采矿活动和靠近大都市地区加剧了碎片化,减少了连通性。广义线性模型表明,PNA的脆弱性随着人口密度和地雷的存在而增加,而随着距大都市的距离和旅游区的存在而降低。这一分析为了解墨西哥每一种陆地PNA面临的当地威胁提供了重要的见解。这些信息对于改进针对这些地区面临的具体威胁的管理计划和保护战略至关重要。

Understanding how socio-ecological drivers shape the interactions between soil ecosystem services (SESs) and soil quality indicators (SQIs) is increasingly critical in mountainous and rapidly urbanizing regions such as Chongqing, China. Accelerating urban expansion across the upper Yangtze River basin has intensified pressures on peri-urban soils through land-use conversion, agricultural intensification, and geomorphological fragmentation. This study investigates soil functionality across Chongqing’s urban–rural ecotone using 485 soil samples collected from representative land-use types, including cultivated lands, citrus orchards, mixed woodlands, and terraced vegetable fields characteristic of the region’s steep and hilly terrain. Paddy–upland rotation systems constituted the dominant land-use category (42.6 %), followed by orchard soils, woodlands, and vegetable terraces. Integrated soil assessments combined with spatial statistical analyses revealed significant spatial clustering of SESs and SQIs (Moran’s I, P < 0.01), highlighting the strong influence of geomorphological heterogeneity and land-management intensity on soil multifunctionality. Soil quality exhibited positive and statistically significant associations with key ecosystem service processes, including nutrient retention, microbial functional diversity, erosion mitigation, pollution buffering, carbon sequestration, and hydrological regulation (r = 0.18–0.51, P < 0.05). A two-step clustering approach further classified 183 administrative villages into four distinct socio-ecological functional zones: (i) agro-innovation and citrus production, (ii) soil erosion control and conservation, (iii) rural environmental enhancement and pollution management, and (iv) ecological restoration and hillside rehabilitation. Across these zones, eleven dominant socio-ecological drivers, topographic ruggedness, slope gradient, farming intensity, fertilizer use structure, road accessibility, livelihood diversification, agricultural labor density, market proximity, vegetation cover, irrigation reliability, and village-level environmental investment, were identified as key determinants of spatial variation in SES–SQI interactions. Overall, the findings provide robust empirical evidence to support region-specific soil governance strategies and sustainable land-use planning, emphasizing the importance of resilient, geomorphology-adaptive soil management under rapid metropolitan expansion.
了解社会生态驱动因素如何塑造土壤生态系统服务(SESs)和土壤质量指标(SQIs)之间的相互作用,在中国重庆等山地和快速城市化地区变得越来越重要。长江上游流域城市扩张的加速,通过土地利用转换、农业集约化和地貌破碎化加剧了城市周边土壤的压力。本研究调查了重庆城乡交错带的土壤功能,使用了485个土壤样本,这些土壤样本来自具有代表性的土地利用类型,包括耕地、柑橘果园、混合林地和梯田菜地,这些土地利用类型具有该地区陡峭丘陵地形的特征。水旱轮作系统是主要的土地利用类型(42.6%),其次是果园土壤、林地和蔬菜梯田。综合土壤评价与空间统计分析相结合,发现SESs和SQIs具有显著的空间聚类(Moran 's I, P < 0.01),突出了地貌异质性和土地管理强度对土壤多功能性的强烈影响。土壤质量与养分保持、微生物功能多样性、侵蚀减缓、污染缓冲、碳固存和水文调节等关键生态系统服务过程呈显著正相关(r = 0.18-0.51, P < 0.05)。两步聚类方法进一步将183个行政村划分为四个不同的社会生态功能区:(i)农业创新和柑橘生产,(ii)土壤侵蚀控制和保护,(iii)农村环境改善和污染管理,以及(iv)生态恢复和山坡修复。在这些区域中,地形崎岖度、坡度、耕作强度、肥料使用结构、道路可达性、生计多样化、农业劳动力密度、市场邻近性、植被覆盖、灌溉可靠性和村级环境投资等11个主导社会生态驱动因素被确定为SES-SQI相互作用空间变化的关键决定因素。总体而言,研究结果为支持区域土壤治理策略和可持续土地利用规划提供了强有力的经验证据,强调了快速大都市扩张下弹性、地貌适应性土壤管理的重要性。

Wetlands support exceptional biodiversity and vital ecosystem services but face accelerating loss and fragmentation worldwide. Predicting how biodiversity varies among wetlands and identifying its key environmental drivers are crucial for conservation, yet traditional approaches often struggle with spatial heterogeneity, data limitations, and the challenge of distinguishing among wetland types. Here, we combined high-resolution, field-delineated wetland boundaries with interpretable machine learning to model species richness and phylogenetic diversity across vascular plants, birds, and fish in all major inland wetland types in Korea. Our models, rigorously validated using spatial block cross-validation, identified the main environmental determinants of biodiversity at the scale of true wetland units. We then used model interpretation techniques to uncover nonlinearities and ecological thresholds in biodiversity–environment relationships. Our results reveal that vegetated area is a universal, dominant predictor across taxa and wetland types, but its effects are nonlinear, with clear saturation or optimum thresholds. Other drivers, such as hydrological stability and landscape composition, were context-dependent. These findings challenge the assumption that “more is always better,” instead highlighting system- and taxon-specific thresholds as effective targets for wetland conservation and restoration. By integrating interpretable machine learning with field-true spatial data, this study offers actionable benchmarks for monitoring, management, and policy, and offers a modeling framework applicable to wetland conservation efforts worldwide.
湿地支持着特殊的生物多样性和重要的生态系统服务,但在世界范围内面临着加速丧失和破碎化。预测湿地生物多样性如何变化并确定其关键环境驱动因素对于湿地保护至关重要,然而传统的方法经常受到空间异质性、数据局限性和区分湿地类型的挑战的困扰。在这里,我们将高分辨率、实地划定的湿地边界与可解释的机器学习相结合,模拟了韩国所有主要内陆湿地类型中维管植物、鸟类和鱼类的物种丰富度和系统发育多样性。我们的模型经过空间块交叉验证的严格验证,确定了真正湿地单元尺度上生物多样性的主要环境决定因素。然后,我们使用模型解释技术来揭示生物多样性-环境关系的非线性和生态阈值。研究结果表明,植被面积是一个普遍的、主导的预测因子,但其影响是非线性的,存在明显的饱和或最佳阈值。其他驱动因素,如水文稳定性和景观组成,则依赖于环境。这些发现挑战了“越多越好”的假设,而不是强调系统和分类群特定的阈值是湿地保护和恢复的有效目标。通过将可解释的机器学习与现场真实空间数据相结合,本研究为监测、管理和政策提供了可操作的基准,并提供了一个适用于全球湿地保护工作的建模框架。

We then used model interpretation techniques to uncover nonlinearities and ecological thresholds in biodiversity–environment relationships. Our results reveal that vegetated area is a universal, dominant predictor across taxa and wetland types, but its effects are nonlinear, with clear saturation or optimum thresholds. Other drivers, such as hydrological stability and landscape composition, were context-dependent. These findings challenge the assumption that “more is always better,” instead highlighting system- and taxon-specific thresholds as effective targets for wetland conservation and restoration. By integrating interpretable machine learning with field-true spatial data, this study offers actionable benchmarks for monitoring, management, and policy, and offers a modeling framework applicable to wetland conservation efforts worldwide.</div></div>","PeriodicalId":54898,"journal":{"name":"Journal for Nature Conservation","volume":"91 ","pages":"Article 127227"},"PeriodicalIF":2.5,"publicationDate":"2026-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146038681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clarifying the effects of national park establishment on regional economic development is essential for ensuring policy sustainability. This study treats Wuyishan National Park Establishment (WNPE) as a quasi-natural experiment and constructs a panel dataset for 138 counties in Fujian, Jiangxi, and Zhejiang provinces over the period 2011–2023. Total factor productivity (TFP) is adopted as a proxy for regional economic development and is measured using the Super-SBM Global Malmquist Index Model. The difference-in-differences (DID) model, mediation effect model, and spatial econometric models are then employed to systematically assess the impact of WNPE on economic development, underlying transmission mechanisms, and spatial spillover effects. The results show that: (1) WNPE significantly suppresses regional economic development, and this finding remains robust to multiple robustness checks. (2) WNPE leads to sluggish growth in the tertiary sector while inducing only a limited withdrawal of the secondary sector, thereby hindering the process of industrial structure adjustment and ultimately exerting a negative impact on regional economic development. (3) Compared to counties with underdeveloped infrastructure, those with well-developed infrastructure can effectively alleviate the negative economic effects of WNPE. (4) At present, the impact of WNPE on the economies of adjacent regions is relatively limited, and no significant spatial spillover effects are observed. Overall, these findings reveal the relationship and mechanism between WNPE and regional economic development. These, in turn, provide the decision-making references for policymakers to develop scientific, targeted, and differentiated national park policies and adjust regional economic development strategies.
明确国家公园建设对区域经济发展的影响是确保政策可持续性的必要条件。本文以武夷山国家公园建设为准自然实验,构建了2011-2023年福建、江西、浙江三省138个县的面板数据集。采用Super-SBM全球Malmquist指数模型对全要素生产率(TFP)作为区域经济发展的指标进行测度。运用差别化差分(DID)模型、中介效应模型和空间计量经济学模型,系统评估了西部农村资本流动对经济发展的影响、潜在传导机制和空间溢出效应。研究结果表明:(1)WNPE显著抑制区域经济发展,且经多次稳健性检验,这一发现具有稳健性。(2) WNPE导致第三产业增长缓慢,第二产业退出有限,从而阻碍了产业结构调整进程,最终对区域经济发展产生负面影响。(3)与基础设施欠发达的县相比,基础设施发达的县可以有效缓解WNPE的负面经济效应。(4)目前,WNPE对相邻区域经济的影响相对有限,没有明显的空间溢出效应。总体而言,这些发现揭示了WNPE与区域经济发展的关系和机制。为决策者制定科学的、针对性的、差别化的国家公园政策和调整区域经济发展战略提供决策参考。

Large carnivores worldwide face significant conservation challenges due to habitat loss, fragmentation, and climate change, which alter resource availability and increase human-wildlife conflicts, while habitat suitability modelling plays a crucial role in predicting these impacts and informing conservation strategies across species and regions. The Syrian brown bear, an endangered subspecies, faces escalating threats in the Kurdistan Region of Iraq (KRI) due to habitat degradation, climate change impacts, and rising human-wildlife conflicts, and this study employs MaxEnt habitat suitability modelling to assess the bear’s current habitat suitability and predict future changes under two contrasting climate scenarios, SSP 126 (low-emission) and SSP 585 (high-emission), projected for the year 2070. The analysis utilizes occurrence data collected between 2009 and 2025, combined with key environmental variables such as slope, elevation, precipitation seasonality, temperature seasonality, and land cover, to map the bear’s ecological preferences and vulnerabilities, with currently suitable habitat spanning 23.68% of the KRI, totaling 12,067.71 km2, and slope (42.40% contribution), elevation (19.70%), and precipitation seasonality (14.60%) identified as the dominant factors shaping habitat suitability. Under the SSP 126 scenario, highly suitable areas are projected to expand significantly to 5.58% (2,844.41 km2) by 2070, particularly in northeastern high-altitude zones, potentially providing refugia for the species, whereas conversely, the SSP 585 scenario predicts a drastic reduction in highly suitable habitat to just 1.56% (795.10 km2), driven by intensifying heat and aridity, which could severely limit the bear’s range. These results highlight the species’ reliance on steep, high-altitude terrains and its susceptibility to rising temperatures, prolonged droughts, and habitat fragmentation, and to ensure the long-term survival of the Syrian brown bear in the KRI, this study underscores the urgent need for targeted conservation strategies, including the creation of habitat corridors to improve connectivity between fragmented populations, community engagement initiatives to mitigate human-bear conflicts, and the implementation of land-use policies to safeguard critical habitats from further degradation.
由于栖息地的丧失、破碎化和气候变化,世界范围内的大型食肉动物面临着巨大的保护挑战,这些挑战改变了资源的可用性,增加了人类与野生动物的冲突,而栖息地适宜性建模在预测这些影响和为跨物种和区域的保护策略提供信息方面发挥着至关重要的作用。叙利亚棕熊是一种濒危亚种,在伊拉克库尔德斯坦地区(KRI)由于栖息地退化、气候变化影响和人类与野生动物冲突加剧而面临日益严重的威胁。本研究利用MaxEnt生境适宜性模型评估了叙利亚棕熊目前的栖息地适宜性,并预测了两种不同气候情景(SSP 126(低排放)和SSP 585(高排放))在2070年的未来变化。利用2009 - 2025年的发生数据,结合坡度、高程、降水季节性、温度季节性和土地覆盖等关键环境变量,分析了熊的生态偏好和脆弱性,目前适宜栖息地面积占KRI的23.68%,总面积为12,067.71 km2,坡度(42.40%),高程(19.70%),降水季节性(14.60%)是影响生境适宜性的主要因素。在SSP 126情景下,预计到2070年,高度适宜的区域将显著扩大到5.58% (2,844.41 km2),特别是在东北部高海拔地区,可能为该物种提供避难所,而相反,SSP 585情景预测,由于高温和干旱加剧,高度适宜的栖息地将急剧减少到1.56% (795.10 km2),这可能严重限制熊的范围。这些结果强调了该物种对陡峭、高海拔地形的依赖,以及对气温上升、长期干旱和栖息地破碎化的敏感性。为了确保叙利亚棕熊在KRI的长期生存,本研究强调了迫切需要有针对性的保护策略,包括创建栖息地走廊以改善碎片化种群之间的连通性,社区参与倡议以减轻人熊冲突。实施土地使用政策,保护重要栖息地免遭进一步退化。

Bengal tigers (Panthera tigris tigris) primarily inhabit fragmented and isolated landscapes, threatening their long-term survival. Habitat fragmentation disrupts movement, reduces genetic diversity, limits prey availability, and increases human-wildlife conflict. Maintaining ecological connectivity is essential for tiger dispersal and population stability. This study employs Remote Sensing and Geographic Information System (GIS) techniques to analyze habitat connectivity across six tiger reserves. Habitat suitability models, incorporating vegetation indices, prey density, and anthropogenic factors, were developed using GIS-based spatial analysis. Using a 200 km threshold, binary and probabilistic indices were applied to identify critical habitat patches for tiger dispersal. The Kanha-Achanakmar landscape emerged as a crucial corridor, exhibiting the highest Betweenness Centrality (BC) and Integral Index of Connectivity (IIC) values, highlighting its role in sustaining tiger populations and facilitating ecological linkages.
Additionally, the study integrates graph-theoretic and game-theoretic models to assess tiger dispersal dynamics. The game-theoretic approach evaluates behavioral strategies and the impact of landscape modifications on population viability. The findings emphasize the Pench-Kanha-Achanakmar corridor as a key dispersal route, supporting prey interactions and ecological stability. This research provides a computational framework for conservation planning, leveraging Remote Sensing, GIS, and mathematical modeling to inform strategies for maintaining long-term habitat connectivity and the persistence of wild tiger populations.
孟加拉虎(Panthera tigris tigris)主要生活在破碎和孤立的景观中,威胁着它们的长期生存。栖息地的破碎破坏了迁徙,减少了遗传多样性,限制了猎物的可得性,并增加了人类与野生动物的冲突。维持生态连通性对老虎的扩散和种群稳定至关重要。本研究采用遥感和地理信息系统(GIS)技术分析了六个老虎保护区的栖息地连通性。基于gis的空间分析方法,建立了包括植被指数、猎物密度和人为因素在内的生境适宜性模型。以200 km为阈值,采用二元指数和概率指数确定老虎扩散的关键生境斑块。坎哈-阿恰纳克马尔景观是一个重要的走廊,表现出最高的中间性中心性(BC)和整体连通性指数(IIC)值,突出了其在维持老虎种群和促进生态联系方面的作用。此外,该研究结合了图论和博弈论模型来评估老虎的扩散动力学。博弈论方法评估了行为策略和景观改变对种群生存能力的影响。研究结果强调,Pench-Kanha-Achanakmar走廊是一个关键的扩散路径,支持猎物相互作用和生态稳定。本研究为保护规划提供了一个计算框架,利用遥感、地理信息系统和数学模型,为维持野生老虎种群的长期栖息地连通性和持久性提供信息。

Promoting the coordination of ecological civilization (EC) and cultural tourism integration (CTI) is crucial for enhancing both ecological conservation and economic development in the Yellow River Basin. Focusing on the 81 prefecture-level cities within the Yellow River Basin, this study constructs two evaluation systems for EC and CTI, respectively. The TOPSIS entropy method, coupling coordinated degree model and geographical detector model are used to analyze the spatiotemporal pattern and driving factors of coupling coordination between EC and CTI from 2011 to 2022. The results show that: (1) The levels of EC and CTI in the Yellow River Basin both exhibit a consistent upward trend respectively. Specifically, the level of EC increases from 0.059 in 2011 to 0.233 in 2022, while the level of CTI rises from 0.078 to 0.102 over the same period. (2) The coupling coordination degree between EC and CTI exhibits a spatial distribution pattern of “downstream > midstream > upstream”. From 2011 to 2022, cities in the coordinated stage showed an inverted “V” shape trend. (3) Technological innovation, green development, social demand, and education levels are all important driving factors. The interaction between green development and government support exerts the most significant influence on the coupling coordination between EC and CTI.
促进生态文明与文化旅游一体化的协调发展,对促进黄河流域生态保护与经济发展具有重要意义。本文以黄河流域81个地级市为研究对象,分别构建了经济效益评价体系和CTI评价体系。采用TOPSIS熵法、耦合协调度模型和地理探测器模型,分析了2011 - 2022年中国电子商务与CTI耦合协调的时空格局及其驱动因素。结果表明:(1)黄河流域EC和CTI水平均呈现一致的上升趋势。其中,EC水平从2011年的0.059上升到2022年的0.233,CTI水平同期从0.078上升到0.102。(2)电子商务与CTI的耦合协调度呈现“下游&中游&上游”的空间分布格局。2011 - 2022年,处于协调发展阶段的城市呈现倒“V”型发展趋势。(3)技术创新、绿色发展、社会需求和教育水平都是重要的驱动因素。绿色发展与政府支持的交互作用对电子商务与CTI的耦合协调影响最为显著。
