While it is expected that future climate change will affect wildfire danger levels by altering fire weather and fuel conditions, there remains a significant gap in understanding how these changes will manifest in the SGP. Therefore, our objectives were to (1) simulate the spatial and temporal dynamics of the Burning Index (BI), a widely used fire danger index in the National Fire Danger Rating System (NFDRS), and high fire danger days based on CMIP5 climate simulations, comparing the 1986–2005 historical period and 2006–2099 under two climate change scenarios (RCP4.5 and RCP8.5), and (2) identify important weather variables driving projected BI changes. We found that the BI would increase at 0.1 × 10 ft per decade under RCP4.5 and 0.4 × 10 ft per decade under RCP8.5. By the end of the 21st century, the southwestern SGP is projected to become a hotspot for increased wildfire danger, its annual high fire danger days are projected to increase by over 25 days (50 %) under the RCP8.5 and more than 15 days (30 %) under the RCP4.5 compared to 1986–2005. The BI is projected to increase in all months except April, with the highest increases occurring during the summer. The primary climate factor contributing to future BI increases is a decline in relative humidity. Interestingly, our simulations suggest a potential decrease in BI for April, likely due to earlier vegetation green-up prompted by rising temperature. Overall, our study outlines future patterns of fire danger in the SGP. These findings are essential for developing long-term preparedness strategies to mitigate wildfire risks and adapt to the new wildfire regimes under changing climate conditions.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"170 ","pages":"Article 112994"},"PeriodicalIF":7.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143094411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding and protecting the ecological security pattern (ESP) of the QTP is essential for ensuring its long-term resilience and stability. This study aims to construct a comprehensive ecological security pattern for the QTP by identifying key ecological sources, corridors, and barriers. We assessed ecosystem service importance, ecological sensitivity, and the locations of nature reserves to determine the spatial distribution of ecological sources. The Minimum Cumulative Resistance (MCR) model and circuit theory were used to map ecological corridors and identify critical pinch points and barriers. The findings show that ecological source areas cover 13.6 % of the QTP’s total area, with most located in the central and eastern regions. We also identified 34 primary and 64 secondary ecological corridors, spanning a total length of 13,667 km. The study highlights the vulnerability of these corridors due to their narrow dimensions, which hinder the movement of species and ecological processes. Furthermore, critical ecological zones such as ecological expansion and conservation areas cover 66.9 % of the region, while ecological protection areas occupy only 10.4 %. The results underscore the need for targeted conservation strategies to enhance ecological connectivity and protect key ecological functions on the QTP.

This study evaluates the ecological vulnerability of the Loess Plateau and aims to provide a theoretical basis for promoting long-term ecological restoration in the region. The “Sensitivity-Resilience-Pressure” (SRP) model was employed to select indicators for assessing ecological vulnerability, while an improved fuzzy analytic hierarchy process (IFAHP) was used to determine the relative weights of these indicators. Using GIS-based overlay analysis, an ecological vulnerability index was calculated, enabling the assessment of spatiotemporal changes and identification of key influencing factors. The results indicate a decreasing trend in ecological vulnerability over the past three decades, with vulnerability levels showing a distinct northwest-to-southeast gradient. Significant spatial variation was observed, with the highest levels of ecological vulnerability concentrated in Inner Mongolia, northern Shaanxi, Ningxia Hui, and Gansu provinces. Vegetation coverage, net primary productivity, and precipitation emerged as the primary drivers of these spatiotemporal changes, with notable interactions between these factors.

This study focuses for the first time on 295 prefecture-level cities and above in China from 2000 to 2020, developing an evaluation system for multi-systems urbanization to assess coupling and coordination. Utilizing methods such as the entropy method, coupling coordination model, Theil index, and Geodetector, this study explores the spatiotemporal differentiation and driving factors of urbanization coupling coordination. The results indicate: (1) The coupling coordination degree of urbanization shows a steady upward trend. Highly coordinated cities are primarily distributed in the core city’s radiation circles, coastal economic belts, provincial capitals in the central and western regions, and northern industrial city zones. Low-coordination cities are mainly found in the Qinghai-Tibet Plateau, Yunnan-Guizhou Plateau, the border areas of Gansu, Shaanxi, Sichuan, Chongqing, and Hubei, the Hetao area of the Yellow River Basin, the agricultural regions of the Huanghuaihai Plain, and the southeastern hilly and mountainous areas.

Herein, we explored the impact of dominant shrubs on the diversity, composition, microbial networks, and community assembly of soil bacteria and fungi on the Qinghai-Tibet Plateau, examining the variations among different soil depths. We found that shrubs significantly increased bacterial and fungal diversity and altered their community composition. Notably, only the diversity of fungi in the topsoil was higher compared to the control grassland. Additionally, shrubs significantly enhanced the complexity of soil microbial networks. However, the complexity of microbial networks among different soil depths under shrubs did not significantly differ, unlike in the control grassland. This suggests that shrubs have a stronger ability to stabilize interspecific relationships among soil microorganisms. The normalized stochasticity ratio and neutral community models indicated that stochastic processes dominated the community assembly of bacteria and fungi, with the influence of these processes diminishing with increasing soil depth. Furthermore, the null model analysis showed that dispersal limitation and homogeneous selection dominated the bacterial assembly, while dispersal limitation dominated the fungal assembly.

This study utilized machine learning models such as Random Forest (RF), AdaBoost, BP-Neural Network (BPNN), and Stacking Ensemble, combining them with topographic and meteorological data, MODIS reflectance data, and grassland height measurement data. The first Eurasian temperate grassland vegetation height dataset was finally generated. The results highlighted the superior performance of the Random Forest with an R² of 0.54, RMSE of 7.39 cm, and MPAE of 49.25 %. Spatial and temporal analyses revealed a discernible spatial distribution in grassland heights across Eurasia, characterized by a consistent decrease from west to east and north to south.
