Vegetation is a main part of ecosystems and an essential indicator for monitoring changes in terrestrial ecosystems. It crucial us to discover the temporal spatial features potential drivers vegetation change promote regional ecological environment protection management. However, it can be difficult pinpoint causes when considering both human activity climate change. We used trend stability method study patterns evolution South Sichuan Urban Agglomeration (SSUA) from 2001 2021 with Google...
The stability and diversity of the natural landscape is critical to maintaining ecological functions a region. However, ecosystems in Yunnan section Tropic Cancer face increasing pressure from climate change, human activities, disasters, which significantly influence their vulnerability. Ecosystem vulnerability determined by structural functional sensitivity, coupled with insufficient adaptability external stressors. While previous research has emphasized effects multidimensional impacts...
Agricultural soils are considered to have great potential for carbon sequestration through land-use change. In this paper, we compiled data from the literatures and studied change in soil organic (SOC) following 'Grain-for-Green' Programme (GGP, i.e., conversion farmland plantation, secondary forests grasslands) China. The results showed that SOC stocks accumulated at an average rate of 36·67 g m−2 y−1 top 20 cm with large variation. current storage could be estimated using initial stock...
China is actively promoting the construction of clean energy to reach its objective achieving carbon neutrality. However, engineering constructions in mountainous regions are susceptible landslide disasters. Therefore, assessment disaster susceptibility indispensable for prevention and risk management projects. In this context, present study involved conducting a field survey at 42 points selected planned site region. According geological geographical conditions region, existing regulation,...
The current imagery of landslides presents multiple challenges, including considerable scale variations among landslides, similarities in spectral characteristics to those bare ground surfaces, and irregular edges. Despite significant progress semantic segmentation achieved by convolutional neural networks (CNNs), the local sensory field CNNs poses difficulties differentiating between surfaces. As a result, efficient accurate landslide extraction remains challenging issue within global...
The tight gas reserves in the Hangjinqi area are estimated at 700 × 109 m3. Since exploration of Hangjinqi, numerous wells already drilled. However, remains an and has yet to become a field. Identifying paleo-depositional framework such as braided channels is beneficial for production companies. Further, pose drilling risks must be properly identified prior drilling. Henceforth, based on significance paleochannels, this study focused addressing depositional sedimentary facies first member...
The Hangjinqi area was explored for natural gas around 40 years ago, but the efficient consideration in this started a decade ago pure exploration. Many wells have been drilled, yet remains an exploration area, and potential zones are still unclear. Lower Shihezi Formation is proven reservoir northern Ordos Basin. This study focuses on second third members of to understand controlling factors faults sedimentary facies distribution, aimed identify favorable accumulation within area. research...
Future gas field development and prospect assessment depend on accurate reservoir parameter characterization. The understanding of the tight sand distribution Shanxi Taiyuan Formations within Hangjinqi area is ambiguous due to presence coal mudstone lithofacies, high heterogeneity, poor resolution seismic data. Thus, it difficult determine reservoir’s thickness. To cope with this challenge, we have employed advanced method constrained sparse spike inversion (CSSI) utilizing 3D nine wells for...
Geological hazard susceptibility assessment (GSCA) is a crucial tool widely utilized by scholars worldwide for predicting the likelihood of geological disasters. The traditional information quantity model in disaster evaluation, which superimposes each evaluation factor without considering their weights, often negatively impacts zoning results. This paper introduces method employing random forest (RF) empowerment to address this issue. involves calculating objective weights based on...
This study considered Shilin World Geopark as the research object and constructed a landscape ecological risk assessment model based on pattern index by using remote sensing image data during five periods between 2000 2020. In addition, it analyzed spatial temporal changes of in region. Spatial autocorrelation analysis was utilized to differences park. The results showed that period, (1) cultivated land, forest rocky desertification land were main types, different types differed, area...
Slope geological disaster is a type of natural that prevalent in the plateau mountainous area. Its occurrence frequently brings substantial harm to local human population and living environment. The aim this research investigate suitability various mapping units for different classifiers process creating susceptibility zoning maps slope disasters evaluate effectiveness each model. Concurrently, map produced by high-accuracy model will assist relevant authorities conducting management tasks...
The integration of deep learning and remote sensing for the rapid detection landslides from high-resolution imagery plays a crucial role in post-disaster emergency response.
