Quantitatively analyzing the impacts of climate and land use changes on ecosystem services has drawn increasing attention over the past decade. However, the assessment approach in the existing studies highly depended on scenarios and modeling, which is unable to distinguish the influences of different land use types and different climate characteristics and to quantify the absolute influence levels of multiple driving factors. Here, we adopted the partial correlation analysis for quantifying relationships between ecosystem services and the seemingly unrelated regression model for assessing impacts of climate and land use changes on ecosystem services. Taking Hainan Tibetan Autonomous Prefecture of Qinghai Province in China from 2000 to 2019 as a case study, we focused on four ecosystem services including material provisioning, climate regulation, water regulation, and soil protection and five driving factors including precipitation, temperature, cropland area, forest area, and grassland area. The results identified the positively dominant driving factor of precipitation on material provisioning, water regulation, and soil protection, and the negatively dominant driving factor of cropland area on material provisioning, climate regulation, and water regulation. The synergy relationships were found between material provisioning and climate regulation, between climate regulation and water regulation, and between water regulation and soil protection, while the trade-off relationships were found between material provisioning and water regulation, and between material provisioning and soil protection. These findings support local policy-making, suggesting that management of climate-related risks and land use plan with a restriction on cropland expansion are expected.

Urban wetland parks serve as essential green spaces that provide cultural ecosystem services, yet their social value remains insufficiently studied. This research evaluates and transfers the social value of ecosystem services in urban wetland parks using the Social Values for Ecosystem Services (SolVES) model, offering a deeper understanding of how environmental factors shape human perceptions. The study focuses on three wetland parks in China: Nanhai National Wetland Park (NNWP) in Guangdong, Donghu Wetland Park (DWP) in Wuhan, and Qinglonghu Wetland Park (QWP) in Beijing. Data were collected through on-site surveys conducted at DWP between March 2021 and December 2023, incorporating visitor preferences and spatial analysis. The results indicate that scenic beauty, recreation, and cultural heritage values are the most prominent, with social values strongly correlated with proximity to water bodies, green spaces, and pedestrian pathways. Gender and age significantly influenced perceptions, with younger respondents placing higher emphasis on recreational benefits, while older individuals valued spiritual and therapeutic aspects. The application of the social value transfer model demonstrated high reliability, successfully predicting ecosystem service values at NNWP and QWP. These findings highlight the importance of integrating ecological and cultural elements in wetland park design to enhance visitor experience and conservation efforts. This study provides a scientific foundation for urban planners and environmental policymakers to develop strategies that maximize the social benefits of wetland parks, ensuring their sustainability in rapidly urbanizing regions.

China’s arid and semi-arid regions are facing severe land degradation. To combat desertification, China has launched large-scale ecological engineering, such as the Three-North Shelterbelt Program (TNSP). This study aims to uncover the feedback mechanisms of ecological spatial networks on ecological engineering effectiveness and analyze the spatial patterns of ecological sources and their ecosystem service responses. It also optimizes techniques for sand fixation, carbon sequestration, and desertification prevention. This study uses multi-source remote sensing and vector data (1986–2021) and complex network theory to extract ecological spatial networks and analyze TNSP’s spatiotemporal trends. The network motif discovery algorithm identifies spatial patterns and explores the relationships between pattern structure, distribution, and topological properties. Finally, it analyzes the response mechanisms between spatial patterns and ecosystem functions. The results show that since the TNSP’s implementation, the number of ecological sources (up by 653, with an area increase of 78,014 km²) and corridors (up by 1,579, with a length increase of 29,591 km) have increased. Spatiotemporal changes in ecological networks reflect ecological engineering effectiveness and guide future optimization. The star, core-linked loop, and triangle patterns can enhance network stability. The star pattern exhibits the highest degree (4.66) and betweenness centrality (53,086), while the triangle and core-linked loop patterns have higher clustering coefficients of 0.315 and 0.250, respectively. Forests demonstrate the strongest sand fixation and carbon sequestration capacities across different patterns. Shrub sources under linear and star patterns significantly enhance ecological value and network stability.

Within an identical soil environment, various pesticides may be commonly identified, but their collective toxicological traits have not been thoroughly investigated. This research sought to elucidate the potential consequences of concurrent exposure to multiple pesticides on soil organisms, with a specific emphasis on examining alterations in transcript and enzyme levels induced by the co-presence of acetamiprid (ACE) and tetraconazole (TET) in earthworms (Eisenia fetida). The results indicated that the joint presence of ACE and TET exhibited an acute synergistic impact on the organisms. Notably, there was a significant elevation in the levels of reactive oxygen species (ROS) and malondialdehyde (MDA), coupled with a substantial suppression of caspase-9 and caspase-3 contents observed in the majority of both individual and combined groups. These findings suggested the occurrence of oxidative stress and cell death. Furthermore, the study revealed a substantial up-regulation of three genes (gst, sod, and crt) and down-regulation of one gene (mt) after exposure to individual pesticides and their mixtures. This pointed towards dysregulation of detoxification processes and oxidative damage. Collectively, the study underscored that the widespread application of these two pesticides might pose potential ecotoxicological risks to the soil ecosystem. In essence, these discoveries enriched our insights into the potential hazards linked to the simultaneous use of multiple pesticides in real-world settings. They underscored the significance of taking into account both synergistic effects and employing judicious pesticide management strategies to alleviate ecological impacts.

Central European forestry is currently facing a challenging situation, striving against climate change impacts. Forest restoration is crucial but monitoring the impact of forest management on biodiversity is needed to incorporate this factor into management decisions. In open-land habitats, Orthoptera are well-known indicators of land use intensity, succession states, and biodiversity. We therefore hypothesized that forest-dwelling Orthoptera may also serve as indicators in temperate forests. We studied the habitat requirements of the common saw bush-cricket, Barbitistes serricauda. As Orthopterans typically depend upon a specific vegetation structure, we assessed canopy structure via hemispherical photography, as well as understory structure and plant diversity via Braun-Blanquet analysis on forest plots with and without the species’ presence. We conducted the study in several forest types. Forest type did not have an overall effect on its presence, but it was less frequent in alluvial forests. When analyzing habitat parameters in detail, the occurrence of the species was significantly associated with canopy openness, light radiation, vertical vegetation structure and herbaceous plant diversity. We calculated its indicator value for these variables, resulting in a significant indication potential for vertical connectivity and gaps in canopy openness. As these parameters have been shown to benefit many other arthropod species, we conclude that Barbitistes serricauda is a suitable indicator for well-structured forest habitats that can promote diversity. Due to its lack of specialization on certain tree species, it may be used in various forest types and under different management strategies.

Mediterranean coastal dune morphology and dynamics are affected by a complex set of biotic and abiotic factors, from both natural and anthropogenic sources. These ecosystems are heavily degraded and endangered nowadays, making monitoring and management actions urgent. Despite their ecological relevance, bryophytes and lichens remain understudied in these ecosystems. This study aims to characterize the cryptogam communities in Balearic coastal dunes and evaluate their potential as bioindicators in Mediterranean dunes. A total of 335 relevés were conducted in 17 dune systems across the Balearic Islands. Plots were grouped in different cryptogam communities, which were characterized by their species composition and different environmental factors measured in the field. Plots could be grouped in a total of five cryptogam communities, which differed in species composition, richness and abundance, and in ecological preferences as indicated by the measured environmental variables. A zonation of communities was not clearly detected, and microsite variables seemed to play an important role. At least two of the cryptogam communities could be considered for monitoring dune system health. A community associated with Bryum dichotomum was related to ruderalization. A second community, characterized by the presence of Ptychostomum torquescens, could indicate an excessive stabilization of mobile dunes by human management. We propose cryptogam communities as bioindicators of Mediterranean coastal dunes health, which should be considered when planning monitoring and management actions.

The drift of benthic invertebrates is closely linked to the stability of their community structure, exerting a direct influence on other aquatic biota and ecosystem functions. Driven by the growing demand for clean hydropower, dam construction and operation have disrupted riverbed structures, changed water properties, and affected flow regimes, leading to alterations in the natural drift pattern and significant loss of benthic invertebrate biomass. Therefore, this review summarizes, for the first time, the responses of benthic invertebrate drift to these changes, including habitat shift, sediment deposition, elevated water temperature, decreased dissolved oxygen levels, and, most importantly, flow fluctuations observed in both regulated rivers and experimental flumes. Furthermore, the development and procedure of a numerical simulation of invertebrate drift are summarised. Based on these processes, we suggest that future field sampling research on benthic invertebrate drift should be expanded to include Asian and high-altitude large regulated rivers. Invertebrate drift simulations could benefit from drawing on fish movement simulations and incorporating biomimetic techniques and tools, such as agent-based models.

底栖无脊椎动物的漂移与其群落结构的稳定性密切相关，对其他水生生物群落和生态系统功能产生直接影响。在清洁水电需求不断增长的推动下，大坝的建设和运行破坏了河床结构，改变了水体性质，影响了水流状态，导致自然漂移模式的改变和底栖无脊椎动物生物量的大量损失。因此，本综述首次总结了底栖无脊椎动物漂移对这些变化的反应，包括栖息地转移、沉积物沉积、水温升高、溶解氧水平下降，以及最重要的是，在管制河流和实验水槽中观察到的水流波动。此外，我们还总结了无脊椎动物漂移数值模拟的开发和程序。基于这些过程，我们建议未来对底栖无脊椎动物漂移的实地取样研究应扩大到亚洲和高海拔的大型管制河流。无脊椎动物漂移模拟可以借鉴鱼类运动模拟，并结合生物模拟技术和工具，如基于代理的模型：缩写：DO，溶解氧；ABM，基于代理的模型。

Mitigating urban carbon emissions is vital for global sustainable development. Low-carbon city pilot programs are key in China’s transition to a low-carbon economy, enhancing energy efficiency, shifting to sustainable energy, and promoting industrial restructuring. This study addresses the radiative and driving effects of these programs on non-pilot cities using Social Network Analysis (SNA) and Quadratic Assignment Procedure (QAP) regression to explore the spatial correlation of carbon emission efficiency (CEE) among cities in the Yangtze River Delta (YRD). Results show that since 2010, CEE spatial correlations have strengthened due to regional integration and pilot initiatives. Core cities like Shanghai, Nanjing, and Suzhou exhibit significant spillover effects, fostering regional low-carbon development. Peripheral cities benefit from these effects, highlighting the importance of core-periphery dynamics. Key factors influencing CEE spatial correlations include geographical proximity, trade openness, economic development, technology development activity, and energy structure, with trade openness enabling access to low-carbon technologies and policy alignment. The study suggests strategically selecting future pilot cities to optimize CEE, focusing on pivotal and economically open cities to enhance regional collaboration and improve carbon reduction efforts across the YRD.

Human-induced alterations in Landscape Patterns (LP) significantly influence hydrological processes, yet their comprehensive impact on rainfall-runoff-sediment relationships (RRSR) remains unexplored. This study introduces the Sediment Transport Modulus per unit of erosive Rainfall (STMR) as a novel metric, alongside the Sediment Transport Modulus (STM) and Suspended Sediment Concentration (SSC), to characterize RRSR. Using hydrometeorological data (1963–2022) and land use maps (1990–2022), the Hushan River Watershed (HSRW) in eastern Poyang Lake, China, was selected to examine the effects of LP on RRSR through LP metrics calculation, correlation analysis, redundancy analysis, and multiple linear regression. The results reveal significant increases in STM, STMR, and SSC, accompanied by notable LP changes during the study period. Overall, LP had a stronger influence on RRSR than sediment yield alone. While the LP of cultivated and forest land showed limited effects on RRSR compared to STM, constructed land exhibited a more pronounced impact. Notably, LP influence diminished when sediment yields exceeded a threshold. Key contributors to RRSR variability included Shannon’s Diversity Index, the percentage of cultivated and forest land, and patch density of cultivated and constructed land. It can be concluded that LP effectively predicted RRSR variations. Strategic LP management, such as enhancing the boundaries between forest and cultivated land, reducing the fragmentation of construction land, and strengthening soil erosion control measures along riverbanks can reduce the transfer of soil during the runoff convergence process. These insights are crucial for optimizing landscapes to enhance ecological resilience.

The Middle Route of China’s South-to-North Water Diversion Project (MR-SNWDP) has substantially alleviated water scarcity in northern China and the water-receiving regions along its route. However, its impact on ecosystem health (EH) is also profound. This study focuses on the 27 urban regions along the middle route of the MR-SNWDP. Using land use data from 2000 to 2022 and Landsat imagery as a foundation, it constructs a research baseline based on remote sensing ecological indices (RSEI) for “vigor-organization-resilience-service (VORS)”. The study employs the Invest model to quantitatively assess ecosystem service provision from 2000 to 2022, revealing changes in EH before and after the water transfer. The research findings indicate that, between 2000 and 2022, land use was predominantly composed of cropland, forest land, and grassland, with frequent conversions between land types. The net loss of cropland reached 1,140,052 hm², primarily due to conversion into built-up land. Overall, the EH has improved, with a spatial distribution pattern showing that the southwest region exhibits better conditions compared to the northeast. Due to land use changes, the EH in the Beijing-Tianjin-Hebei (BTH) region has remained suboptimal. In terms of periods, prior to the water transfer (2000–2015), EH slightly declined, with reductions in ecosystem organization (EO), ecosystem resilience (ER), and ecosystem service (ES) values. Conversely, the ecosystem vigor (EV) value showed a notable increase. After the water transfer (2015–2022), EH showed a marked increase. Except for a slight decrease in ES values, all other indicator values exhibited varying degrees of improvement.
