This study aims to investigate the coordinated relationship between agricultural carbon emissions and economic growth, thereby laying a foundation for China's green socio-economic transformation. First, by employing spatial autocorrelation and the Environmental Kuznets Curve (EKC) theory, we identify the spatial patterns of ACE and classify the development stages of the provinces. Second, by integrating the Tapio decoupling model with Markov chains, we reveal the dynamic evolutionary paths and stability of the agricultural \"carbon economy\" decoupling status. Finally, the Logarithmic Mean Divisia Index (LMDI) decomposition is utilized to quantitatively identify the key driving factors affecting the decoupling process. The results show that China's provincial ACE exhibit significant and persistent spatial agglomeration characteristics. The provinces can be classified into six distinct development stages, with Group AP IV having entered a potential carbon peaking period, whereas some major agricultural production areas still face formidable emission reduction challenges. Provinces widely face a high-probability risk of reverting from a state of strong decoupling to an unfavorable one. Even for provinces with peaking potential, the probability of maintaining strong decoupling is merely 67.6 %, while for major agricultural production areas, the probability of status deterioration is as high as 71.7 %, suggesting that China's agricultural low-carbon transition predominantly follows an extensive dynamic path. Energy Utilization Efficiency (EUE) is the most critical driving force in promoting agricultural carbon decoupling, and across all regional groups, the enhancement of EUE plays a dominant role in emission reduction. This study extends the theoretical understanding of the dynamics of agricultural 'carbon-economy' decoupling, provides a scientific basis for the formulation of regionally differentiated agricultural low-carbon policies.</div></div>","PeriodicalId":51043,"journal":{"name":"Ecological Modelling","volume":"509 ","pages":"Article 111266"},"PeriodicalIF":2.6,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144694941","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}

This study evaluates restoration outcomes at 756 historical mine sites in the Xiang River Basin from 2000 to 2020, focusing on four key ecosystem services: water yield, water purification, soil retention, and carbon sequestration. The evaluation is based on a systematic framework that incorporates three analytical dimensions: landscape pattern evolution, ecosystem service changes, and spatial coupling with key ecological spaces. Our results showed that landscape fragmentation around 84 % of mine sites was significantly reduced, with patch structures becoming more integrated and regular, particularly in areas with dense mine site distributions. Nevertheless, overall landscape connectivity and system stability remained relatively low. In terms of ecosystem services, 52 % of mine sites has experienced a decline in service capacity, with water yield and water purification services in the middle and lower reaches of the basin showing the most notable deterioration. Encouragingly, restoration efforts at several critical ecological nodes have achieved substantial outcomes, demonstrating the potential of precision-based ecological interventions and offering valuable experience for future regional ecological recovery.

Subsequently, the calibrated model was employed to simulate the spatio-temporal distribution of annual and monthly NPP within forest ecosystem of the Poyang Lake Basin (PYLB) in the subtropical region from 1960 to 2022.

Animal movement modelling research has focused largely on statistical inference for long-term spatial distributions of animal movement and changes in behavioural states, with relatively little attention being given to short-term animal movement forecasting. We propose a straightforward forecasting framework that employs a continuous-time Ornstein–Uhlenbeck (O–U) velocity process as the foundation for a movement forecast system. Specifically, we incorporate a direction modification method to ensure directional persistence and to guide the movement towards preferred historical locations and pathways. We demonstrate our forecasting methods using movement data from 11 years of Southern Resident killer whale (SRKW) movement data. We evaluate its forecasting performance on a historical trajectory of the SRKW. The resultant ensemble forecast outcome defines a 90% probability region indicating the most likely region where animals may be found for a specific forecast horizon. Our stochastic dynamic framework successfully predicts an SRKW trajectory up to three hours ahead with incoming observations covered by our 90% probability regions. This shows the approach is suitable for our conservation objectives of using short-term SRKW forecasts to aid in dynamic management of marine traffic and to reduce whale-vessel interactions. Importantly, our forecasting framework is versatile and can be readily applied to a wide range of animal species, provided there is a historical trajectory database available. It can be initiated with observed locations and conducted in real time for ecological management plans, and it can also be integrated into data-assimilative forecasting.</div></div>","PeriodicalId":51043,"journal":{"name":"Ecological Modelling","volume":"509 ","pages":"Article 111254"},"PeriodicalIF":2.6,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144685904","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}

Rather, we found that the flushing scheme would increase the nutrient transport towards the Northern regions of the system, as nutrient retention capacity of the lakes in the network was limited.

To address this, the present study combines a Self-Organizing Map (SOM) neural clustering model with complex network analysis to identify ecological sources and enhance overall network structure.

We develop a cellular-automata simulation approach and couple it with minimalist litter and plant water balance models to examine the influence of stand size, species composition (conifers vs. broadleaf-deciduous species), and ditching impact on fire spread. We find that smaller forest stand sizes greatly reduce landscape fire risk, where for instance, decreasing stand size from 100 to 1 hectares leads to a fivefold reduction in fire risk. Diversifying tree species composition and avoiding landscape ditching can further reduce fire risk, especially when stand size is large. The effect of forest heterogeneity on fire risk is comparable to that of variability of environmental factors such as air humidity, highlighting the importance and potential of forest heterogeneity in fire mitigation.
