Topic Information

Dear Colleagues,

Due to the impacts of climate and environmental change, the frequency, intensity, and scope of extreme weather events have increased, leading to ecological vulnerability and frequent disasters such as earthquakes and floods in various regions. Ecosystems directly contribute to social and economic development by providing tangible material products and intangible services for human beings. However, the ecological environment has experienced a trend of deterioration under the combination of global warming and human activities. Implementing ecological environment assessments and clarifying the causes and mechanisms of disasters can provide a scientific basis and data support for eco-environmental protection measures and disaster reduction. With a focus on multisource remote sensing and social sensing data, this Topic aims to collect articles providing approaches, methods, and tools for assessing and revealing the changing trends and characteristics of ecological vulnerability and multiple types of disasters. Moreover, this Topic is devoted to promoting advances in understanding and modeling the relationships between global change and regional ecological vulnerability, accurately identifying vulnerability characteristics, exploring disturbance mechanisms, and examining the impact of key vulnerability elements and their interrelationships with disaster risk. We invite you to submit original research articles or review articles on topics related to ecological vulnerability assessment methods, disaster monitoring, or risk assessment utilizing multisource remote sensing images. Articles can describe innovative technological developments; introduce experiments, numerical modeling, case studies, or analytical research; or evaluate the future prospects of emerging technological solutions and propose suggestions for potential approaches.

As the core carrier of historical and cultural identity, cultural heritage is facing multiple threats such as natural disasters, human activities and its own vulnerability. There is an increasing number of studies on cultural heritage risk assessment around the world, but the risk assessment of cultural heritage in China has not been fully explored. In this paper, the LightGBM model was used to quantitatively analyze the main influencing factors of cultural heritage risk along the Ancient Tea Horse Road in Sichuan, and spatial analysis was carried out by combining geographic information system (GIS) technology. In order to improve the interpretability of the assessment results, the SHAP method was introduced to systematically evaluate the contribution of each influencing factor to the risk of cultural heritage. This study identified seven major risk factors, including landslides, collapses, debris flows, earthquakes, soil erosion, urban road networks, and cultural heritage vulnerability, and constructed a risk assessment framework that comprehensively considers the vulnerability to natural and synthetic factors and the heritage itself. The results of the assessment divided the risk of cultural heritage sites into five levels: very low, low, medium, high and very high, and the results showed that 52.36% of the cultural heritage was classified as at medium and high risk and above, revealing the severe security situation faced by cultural heritage in the region and indicating the urgent need to take effective protective and management measures to deal with multiple risks and challenges.

Urban flood susceptibility has emerged as a critical challenge for cities worldwide, exacerbated by rapid urbanization. This study evaluates urban flood susceptibility under different Shared Socioeconomic Pathways (SSPs) in the context of urbanization. A coupled modeling approach integrating the System Dynamics (SD) model and the Future Land Use Simulation (FLUS) model was employed to project future land use changes under sustainable development, moderate development, and conventional development scenarios. Additionally, an XGBoost model was developed to assess urban flood susceptibility. The results indicate that urban construction land will continue to increase over the next 30 years, with the extent of growth varying across different scenarios. Notably, under the conventional development scenario, rapid economic growth leads to a significant expansion of built-up land and a sharp decline in ecological land, which in turn exacerbates the urban flood susceptibility. Consequently, urban flood susceptibility is projected to increase across all three scenarios, albeit at varying rates. Specifically, under the sustainable development scenario, 27% of Guangzhou is projected to face high flood risk. In the moderate development scenario, the area classified as high-risk increased by 868.73 km2. Under the conventional development scenario, the high-risk area expanded from 1282.9 km2 in 2020 to 2761.33 km2, representing a 16% increase. These differences are primarily attributed to changes in land use, which alter surface runoff and subsequently enhance the city’s vulnerability to waterlogging. This study provides a comprehensive framework for assessing urban flood susceptibility in the context of urbanization, offering valuable insights for formulating targeted flood prevention and mitigation strategies.

Flooding is among the world’s most destructive natural disasters. From 27 July to 1 August 2023, Zhuozhou City and surrounding areas in Hebei Province experienced extreme rainfall, severely impacting local food security. To swiftly map the spatial and temporal distribution of the floodwaters and assess the damage to major crops, this study proposes a water body identification method with a dual polarization band combination for synthetic-aperture radar (SAR) data to solve the differences in water body feature recognition in SAR due to different polarization modes. Based on the SAR water body extent, the flood inundation extent was mapped with GF-6 optical data. In addition, Landsat-8 data were used to generate information on significant crops in the study area, while Sentinel-2 data and the Google Earth Engine (GEE) platform were used to classify the extent of crop damage. The results indicate that the flood inundated 700.51 km2, 14.10% of the study area. Approximately 40,700 hectares (ha) or 8.46% of the main crops were affected, including 33,700 ha of maize, 4300 ha of vegetables, and 2800 ha of beans. Moderate crop damage was the most widespread, affecting 37.62% of the crops, while very extreme damage was the least, affecting 5.10%. Zhuozhou City experienced the most significant impact, with 13,700 ha of crop damage, accounting for 33.70% of the total. This study provides a computational framework for rapid flood monitoring using multi-source remote sensing data, which also serves as a reference for post-disaster recovery, agricultural production, and crop risk assessment.

Based on 143 Sentinel-1A images from January 2020 to December 2022, this study used SBAS-InSAR technology to monitor the surface deformation of the tailings pond and analyzed and predicted the surface deformation laws in southeast Tibet. Overall, the surface deformation of the tailings pond was significant and there were many areas where the deformation was uneven. The typical subsidence areas were mainly located in the northern part of the right tailings pond and the southern part of the left tailings pond. From a temporal perspective, the subsidence in the tailings pond showed a certain periodic downward fluctuation. Specifically, cumulative subsidence from January to September each year displayed a clear downward trend, reaching its maximum around September. This was followed by a slight uplift in October and November, after which a notable downward trend resumed from December until the following September. Based on spatial scale analysis, the changes in the tailings pond were relatively stable before May 2020. After that, the northern part of the right tailings pond showed a sinking trend, while the southern part exhibited uplift, and the central part remained relatively stable. Conversely, the southeastern part of the left tailings pond showed an uplifting trend, while the northern, central, and western parts experienced subsidence. Based on the Holt–Winters exponential smoothing model, we predicted the cumulative subsidence for 10 monitoring points in 2023. The northern part of the right tailings pond is expected to continue showing a significant subsidence trend in 2023. A prominent subsidence center is projected to emerge in the central part of the left tailings pond, and we should strengthen monitoring to avoid the disaster risk in the mining area. Full article

Due to the inherent limitations in remote sensing image quality, seasonal variations, and radiometric inconsistencies, river extraction based on remote sensing image classification often results in omissions. These challenges are particularly pronounced in the detection of narrow and complex river networks, where fine river features are frequently underrepresented, leading to fragmented and discontinuous water body extraction. To address these issues and enhance both the completeness and accuracy of fine river identification, this study proposes an advanced fine river extraction and optimization method. Firstly, a linear river feature enhancement algorithm for preliminary optimization is introduced, which combines Frangi filtering with an improved GA-OTSU segmentation technique. By thoroughly analyzing the global features of high-resolution remote sensing images, Frangi filtering is employed to enhance the river linear characteristics. Subsequently, the improved GA-OTSU thresholding algorithm is applied for feature segmentation, yielding the initial results. In the next stage, to preserve the original river topology and ensure stripe continuity, a river skeleton refinement algorithm is utilized to retain critical skeletal information about the river networks. Following this, river endpoints are identified using a connectivity domain labeling algorithm, and the bounding rectangles of potential disconnected regions are delineated. To address discontinuities, river endpoints are shifted and reconnected based on structural similarity index (SSIM) metrics, effectively bridging gaps in the river network. Finally, nonlinear water optimization combined K-means clustering segmentation, topology and spectral inspection, and small-area removal are designed to supplement some missed water bodies and remove some non-water bodies. Experimental results demonstrate that the proposed method significantly improves the regularization and completeness of river extraction, particularly in cases of fine, narrow, and discontinuous river features. The approach ensures more reliable and consistent river delineation, making the extracted results more robust and applicable for practical hydrological and environmental analyses. Full article

The ecological health of Hebei Province is critical to the sustainable development of the Beijing–Tianjin–Hebei region. However, the increasing intensity of land use in recent years has placed significant pressure on local ecosystems, making it essential to understand how land use changes affect ecological resilience across different regions and time periods. This study takes Hebei Province as the research area and selects four time points—1990, 2000, 2010, and 2020—to systematically evaluate the spatiotemporal variations in ecological resilience and land use intensity using indicators such as the water resource supply, climate regulation, hydrological regulation, biodiversity, the landscape pattern index, and land use types. This study employs spatial analysis methodologies, including the spatial autocorrelation model and the Geographically Weighted Regression (GWR) model, to systematically analyze spatial clustering patterns, spatial heterogeneity, and influencing mechanisms. Scenario simulations are also conducted to predict ecological resilience trends in 2030 under a sustainable development scenario. The results indicate that (1) over the past 30 years, both ecological resilience and land use intensity in Hebei Province have generally increased, with notable spatial disparities among cities. (2) Moreover, a significant negative correlation exists between ecological resilience and land use intensity, with the GWR model revealing pronounced spatial heterogeneity. The impact of land use intensity on ecological resilience is relatively minor in highly urbanized central and southern regions, while northern and northwestern regions are more sensitive to changes, highlighting the need for better coordination between land use planning and ecological protection. (3) Finally, scenario simulations predict a slight overall decline in ecological resilience by 2030, with central and southern cities projected to experience the largest decreases, while some northern cities are expected to see modest improvements. These findings underscore the importance of regionally differentiated land use management and ecological protection strategies. This study provides scientific evidence and planning recommendations to improve ecological resilience and environmental protection in Hebei Province. At the same time, this study contributes to a deeper understanding of how land use dynamics influence ecological resilience. The methodologies and findings presented in this study can also be applied to guide sustainable development planning in other rapidly urbanizing areas, providing a valuable framework for addressing regions facing similar ecological challenges.

Global changes have led to significant changes in soil erosion on the Loess Plateau. Soil erosion leads to the degradation of land resources and a decline in soil fertility, adversely affecting agricultural production and the socioeconomic situation. Therefore, revealing the spatiotemporal evolution patterns of soil erosion in the Loess Plateau region and investigating the influencing factors that contribute to soil erosion are crucial for its management and restoration. In this study, the RUSLE monthly model and the Geodetector model were utilized to reveal the spatiotemporal trends of soil erosion in the Loess Plateau from 2000 to 2020 and to determine the dominant influencing factors in different periods. The main results are as follows: (1) From 2000 to 2020, the soil erosion in the Loess Plateau initially weakened and then intensified, indicating that precipitation and precipitation intensity have different effects on surface soil. (2) From 2000 to 2015, the area experiencing slight and mild erosion increased. This is attributed to the increase in vegetation coverage in the Loess Plateau region, which has alleviated soil erosion in the area. (3) From 2000 to 2020, zones of severe soil erosion were mainly located in the cities of Yan’an and Yulin and their surrounding areas. The gravity center of soil erosion shifted northwestward from Yan’an City overall, indicating an improvement in the soil erosion conditions in the Yan’an area. (4) The predominant level of soil erosion across different land-use types was slight erosion, accounting for over 40%. This may be a result of forestry ecological projects that effectively reduce soil loss. (5) In slope zones of 0–5°, slight erosion accounted for the largest area proportion. As the slope increased, the area proportion of severe and extremely severe erosion also increased. This is attributed to the protective role of vegetation on soil in gentle slope areas. (6) From 2000 to 2020, vegetation was the dominant single factor influencing the spatiotemporal changes in soil erosion, while the interactions between vegetation and land use had the largest explanatory power, indicating that changes in land-use types partially affect variations in vegetation coverage. Our research findings could provide important data support for soil erosion control and eco-environment restoration in the Loess Plateau region. Full article
