As a result of the unique geographical characteristics, pastoral lifestyle, and economic conditions in Mongolia, its fragile natural ecosystems are highly sensitive to climate change human activities. The normalized difference vegetation index (NDVI) was employed this study as an indicator growth status vegetation. Sen’s slope, Mann–Kendall test, detector modelling methods were used assess spatial temporal changes NDVI response variations activities Mongolia from 1982 2015. corresponding...

Abstract New evidence indicates that sand availability does not only control dune type but also the underlying growth mechanism and subsequent orientation. Here we numerically investigate development of bedforms in bidirectional wind regimes for two different conditions availability: an erodible bed or a localized source on non-erodible ground. These are associated with independent mechanisms and, both them, present complete phase diagrams shape On bed, linear dunes observed over entire...
Desertification is one of the most serious ecological and environmental problems in arid regions. Low-cost, wide-ranging, high-precision methods are essential for formulation appropriate strategies quantitatively monitoring desertification. In this study, based on Google Earth Engine Landsat images, six machine learning were used to monitor desertification dynamics 1990–2020 Mongolia. The spatiotemporal distributions changes at different stages analyzed using gravity center change intensity...
Abstract Desertification research in arid and semi-arid regions has always been actively pursued. In China, the problem of desertification Xinjiang also received extensive attention. Due to its unique geography, many scholars have conducted corresponding on status Xinjiang. this paper, we comprehensively reviewed Xinjiang, compared underlying mechanisms conditions after implementation ecological control projects. On a larger scale, can be divided into soil salinization inside oases sandy...
Abstract We investigate the development and steady states of transverse dunes for ranges flow depths velocities using a cellular automaton dune model. Subsequent to initial bed instability, pattern coarsening is driven by form interactions. Collisions lead two types coalescence associated with upstream or downstream dominant dunes. In addition, single collision‐ejection mechanism enhances exchange mass between adjacent forms (throughpassing dunes). The power law increases in wavelength...
Owing to the combined effects of climate change and human activities, type desertification in arid regions Asia has undergone profound changes, problem become increasingly prominent. To help address this problem, study clarifies transformation trends characteristics types across discusses key areas for prevention control. Based on a series Landsat satellite images, with classification method degree machine learning model, types, trends, conversion degrees were systematically evaluated. In...
Abstract As a member of the Chinese modeling groups, coupled ocean-ice component Academy Sciences’ Earth System Model, version 2.0 (CAS-ESM2.0), is taking part in Ocean Model Intercomparison Project Phase 1 (OMIP1) experiment phase 6 Coupled (CMIP6). The simulation was conducted, and monthly outputs have been published on ESGF (Earth Grid Federation) data server. In this paper, experimental dataset introduced, preliminary performances ocean model simulating global temperature, salinity, sea...
Collision among barchan dunes is a main cause for the dune swarm to achieve size and speed selection, it can be divided into two patterns: coalescence ejection. Here, three-dimensional (3D) cellular automaton model applied collectively study effects of inter-dune space relative on these collision patterns. A parameter established that includes transition surface distinguishing Confirmed by field observations subaquatic experiments, comprehensive depiction between ejection provided, which may...
Abstract The glacier mass balance, area change, and runoff in the Yarkant River Basin (YRB) Beida (BRB) were estimated from 1961 to 2006 by employing a modified monthly degree‐day model. Comparisons between simulated observed equilibrium line altitude, suggest that model can be used analyze long‐term changes of balance YRB BRB. balances BYB both have significantly decreasing trend with −4.39 mm ‐1 −8.15 because significant increase ablation caused increasing summer air temperatures,...
Dust emission is a common catastrophic weather phenomenon in Northern China. This not only causes environmental problems, such as air pollution, but also has an important impact on the global dust cycle and climate change. On basis of observation data 44 surface meteorological stations Tarim Basin from 1989 to 2021, combined with aerosol optical depth (DAOD), mass concentration (DUSMASS) wind speed data, this paper analyses spatial temporal characteristics over past 33 years. Results show...

In this study, we propose experimentally demonstrate a topological that exhibits exceptional transmission robustness, unaffected structural curvature. The constructed using subwavelength structure combines the benefits of properties, such as broadband...
In recent years, brain-computer interfaces (BCIs) leveraging electroencephalography (EEG) signals for the control of external devices have garnered increasing attention. The information transfer rate BCI has been significantly improved by a lot cutting-edge methods. exploration effective preprocessing in interfaces, particularly terms identifying suitable methods and determining optimal sequence their application, remains an area ripe further investigation. To address this gap, study...
Nonpersistent joints that commonly exist in nonpersistent discontinuities exhibit complex shearing behavior due to the intervals between rock bridges. The influence of bridges on bearing capacity is difficult determine two main factors: uncertainty proportion bridge area (or joint area) terms geometry and resulting variation normal stress distribution dynamics. As an innovative study, this paper investigates effects persistence sequence mobilization by recording deformation pattern parts...
ABSTRACT This paper presents a semi‐analytical method for the stress and displacement of shallow buried lined tunnel based on complex variable under full‐slip contact condition, that is, along interface between surrounding rock/soil mass lining, radial stresses displacements are continuous, shear equal to zero. In presented solution, interaction as well self‐weight considered. The equations boundary conditions continuity put forward in this paper. A comparison obtained by analytical solution...
Abstract Unlike ripples, there are only few numerical studies on grain size segregation at the scale of dunes in aeolian environments. Here we use a cellular automaton model to analyze vertical sorting granular mixtures under steady unidirectional flow conditions. We investigate feedbacks between dune growth and mechanisms by varying coarse grains their proportion within bed. systematically observe development horizontal layer top which sorted bed forms may grow amalgamation. The formation...
