The ecological environment is the foundation of human survival and development. China's has undergone a historic transition from partial improvement to overall improvement. In this paper, long time series NDVI data (1998–2018) are used evaluate change spatiotemporal that taken place in China over last 20 years, at different scales (regional, provincial, county, grid scales). Combined with typical areas, causes revealed. results show about one-third China, improved, 10%, deteriorated....
Abstract The comprehensive understanding of the occurred changes permafrost, including mean annual ground temperature (MAGT) and active layer thickness (ALT), on Qinghai‐Tibet Plateau (QTP) is critical to project permafrost due climate change. Here, we use statistical machine learning (ML) modeling approaches simulate present future MAGT ALT in regions QTP. results show that combination ML method reliable ALT, with root‐mean‐square error 0.53°C 0.69 m for respectively. (2000–2015) area QTP...
Construction sites are considered high-risk working environments. Safety risk analysis of construction is one the important aspects safety management. However, existing methods typically face overreliance on subjective experience and cannot reflect real-time level projects. Crucial information about accidents implies a complex semantic network that can obtain objective quantitative data then serve risk. Therefore, knowledge-graph-improved dynamic method for behavior-based (BBS) management...
Abstract Soil hydrothermal regime of the active layer in permafrost regions Qinghai‐Tibet Plateau (QTP) is important to underlying and climate change dynamics Asia. However, a large bias still exists current land surface models representation soil temperature moisture. This study assessed augmented Noah model with multiparameterization options (Noah‐MP) for simulating at Tanggula (alpine meadow) Beiluhe swamp) stations located QTP. The results showed that default Noah‐MP tended underestimate...
Abstract The characteristics of long‐term variation for extreme precipitation events were analyzed at the Tanggula site in continuous permafrost regions Qinghai‐Tibetan Plateau (QTP). In addition, impacts summer on soil thermal‐moisture dynamics also investigated. results showed that local indices fluctuated significantly and trend magnitudes very wet days (R95p), annual total wet‐day (PRCPTOT), number heavy (R10mm), maximum length dry spell (CDD), simple daily intensity index (SDII) larger...
Precipitation plays a vital role in the hydrological cycle, directly impacting water resource management and prediction of flood drought risks. This study explores an approach by applying Bayesian Model Averaging (BMA) algorithm to merge multiple precipitation datasets, aiming improve accuracy estimates for simulations. The BMA framework combines four widely used datasets—CHIRPS, ERA5, GSMaP, IMERG—across Ganjiang River Basin China from 2008 2020. To evaluate performance merged dataset,...
Precipitation plays a vital role in the hydrological cycle, directly affecting water resource management and influencing flood drought risk prediction. This study proposes Bayesian Model Averaging (BMA) framework to integrate multiple precipitation datasets. The enhances estimation accuracy for simulations. BMA synthesizes four products—Climate Hazards Group Infrared with Station (CHIRPS), fifth-generation ECMWF Atmospheric Reanalysis (ERA5), Global Satellite Mapping of (GSMaP), Integrated...
Abstract. Extensive and rigorous model intercomparison is of great importance before application due to the uncertainties in current land surface models (LSMs). Without considering forcing data parameters, this study designed an ensemble 55 296 experiments evaluate Noah LSM with multi-parameterization (Noah-MP) for snow cover events (SCEs), soil temperature (ST) liquid water (SLW) simulation, investigated sensitivity parameterization schemes at a typical permafrost site on Qinghai–Tibet...
Gross primary productivity (GPP) is a measure of carbon uptake by terrestrial ecosystems for neutrality and serves as key indicator the Sustainable Development Goals. The instantaneous Fraction Absorbed Photosynthetically Active Radiation (FAPAR) applied in GPP estimation light use efficiency (LUE) models. However, an obvious time scale mismatch exists between FAPAR daily accumulated GPP. In study, we explored potential temporal upscaling improving simulation. absorbed photosynthetically...
Ensuring the grain supply-demand balance and achieving security had been main tasks for government of Bangladesh. On supply side, Bangladesh’s products has increased substantially, with an average annual growth rate 1.99 million tons in 1998–2018. Domestic production, especially rice accounted largest proportion its structure. However, under constraints resources environment, imports international aid were needed to ensure a stable sustainable supply. demand continued grow at 2.09 structure...
Actual evapotranspiration (ETa) is important since it an link to water, energy, and carbon cycles. Approximately 96% of the Qinghai-Tibet Plateau (QTP) underlain by frozen ground, however, ground observations ETa are particularly sparse–which especially true in permafrost regions–leading great challenge for accurate estimation ETa. Due impacts freeze-thaw cycles degradation on regional ET process, therefore urgent find a reasonable approach regions. The complementary relationship (CR)...
Abstract The surface energy balance is a key issue in land process research and important for studies of climate hydrology. In this paper, the fluxes (net radiation, ground heat flux, sensible flux latent flux) at Tanggula (TGL) Xidatan (XDT) sites were measured distributions regional on Tibetan Plateau obtained using revised system (SEBS) model. results show that have obvious seasonal variations. At both sites, highest spring lowest summer, summer winter. high elevation, snow cover,...
The ground surface soil heat flux (G0) is very important to simulate the changes of frozen and active layer thickness; in addition, freeze-thaw cycle will also affect G0 on Tibetan Plateau (TP). As could not be measured directly difficult observed TP situ due its high altitude cold environment, most previous studies have applied existing remote sensing-based models estimate without assessing whether selected model best one those for study regions. We use in-situ observation data collected at...
In recent years, much attention has been given to the current situation and trend regarding economic development in Democratic People’s Republic of Korea (DPRK), which urbanization is an important indicator. present study, (i) urbanized area estimated using DMSP/OLS NPP/VIIRS, (ii) spatial pattern change characteristics typical cities are revealed, (iii) scale developmental stage major DPRK judged through comparison. Although relatively closed, financial crisis 2008 indirectly affected its...
The ground surface soil heat flux (G0) quantifies the energy transfer between atmosphere and through land surface. However; it is difficult to obtain spatial distribution of G0 in permafrost regions because limitation situ observation complication conditions. This study aims at developing an improved parameterization scheme applicable Qinghai-Tibet Plateau under clear-sky We validated several existing remote sensing-based models estimate by analyzing measurement data. Based on validation...
ABSTRACT Using 30 years of NCEP/NCAR reanalysis data from winter (January), along with daily precipitation the China Meteorological Administration (CMA), this study employed an objective recognition method to classify southern branch troughs (SBTs) into eastern and western types. Subsequently, analysis was conducted identify structural characteristics each type evaluate their effects on precipitation. The findings reveal that SBTs are located at different coordinates 500 hPa, affecting...
