Abstract Coastal ecosystems provide a range of services including erosion prevention, clean water provision and carbon sequestration. With climate change, the rapid change in frequency intensity tropical cyclones may alter composition themselves potentially degrading they provide. Here we classify global ecoregions into dependent, resilient vulnerable show that combined 9.4% surface all terrestrial is susceptible to transformation due cyclone pattern changes between 1980–2017 2015–2050 under scenario SSP5-8.5 using STORM model. Even for most already experiencing winds >60 m s −1 regularly, average interval two storms projected decrease from 19 12 years which close their recovery time. Our study advocates shift consideration impact immediate damage effects on long-term natural cycles.

Published: Feb. 17, 2024

Vegetation classification, biomass assessment, and wildfire dynamics are interconnected wildfire-ecosystem components. The Chongli District, located in Zhangjiakou City, was the venue for skiing at 2022 Winter Olympics. Its high mountains dense forests create a unique environment. establishment of alpine ski resorts highlighted importance comprehensive forest surveys. Understanding vegetation types their is critical to assessing distribution local resources predicting likelihood fires. This study used satellite multispectral data from Sentinel-2B classify surface District through K-means clustering. By combining this classification with inversion model, total survey area can be calculated. equation established based on remote sensing terrain information have strong correlation (shrub R2 = 0.811, broadleaf 0.356, coniferous 0.223). These coefficients key indicators our understanding relationship between actual biomass, reflecting performance model. Taking shrubland as an example, coefficient 0.811 shows model’s ability accurately predict type vegetation. In addition, multiple linear regression, optimal shrub, broadleaf, models were obtained, overall accuracy reaching 93.58%, 89.56%, 97.53%, respectively, meeting strict requirements accuracy. successfully conducted using data. research results important implications prevention control

Forest fire susceptibility mapping plays a crucial role in forest management and disaster prevention. However, existing research often neglects the selection of non-fire data during model construction, resulting limited prediction accuracy. To address this issue, we propose an innovative DBSCAN-DNN that optimizes to enhance precision. Using VIIRS GLC_FCS30D datasets, created spatial database for Xichang's dry seasons from 2012 2022, incorporating topography, meteorology, vegetation, human activities. Based on this, employed DBSCAN algorithm cluster points accurately delineated affected areas. Subsequently, selected samples outside these regions training DNN model. Through comparative experiments, found exhibited excellent performance predicting Xichang City, with AUC value 0.925 significant improvements accuracy (0.834), precision (0.800), recall (0.891), F1-score (0.843), Kappa coefficient (0.669). Additionally, conducted SHAP analysis delve into contributions interactions various factors influencing susceptibility. This finding offers valuable insights selecting sample
