Significance The Yellow River (YR) is the cradle of Chinese civilization. It supports agriculture, social prosperity, and human survival. YR runoff sediment load have sharply fallen since late 1980s. We reconstructed natural history for middle reach from 1492 to 2013 CE. found that recent low observed unprecedented over past five centuries, mainly due combination decreasing precipitation increasing water consumption by activities, particularly agricultural irrigation. Our results provide a...
The Qinghai-Tibet (QT) Plateau Engineering Corridor is located in the hinterland of QT Plateau, which highly sensitive to global climate change. Climate change causes permafrost degradation, subsequently affects vegetation growth. This study focused on dynamics and their relationships with human activities region surrounding Corridor. changes were inferred by applying trend analysis, Mann-Kendall test abrupt analysis. Six key regions, each containing 40 nested quadrats that ranged size from...
Abstract The Asian Summer Monsoon (ASM) affects ecosystems, biodiversity, and food security of billions people. In recent decades, ASM strength (as represented by precipitation) has been decreasing, but instrumental measurements span only a short period time. initiation the dynamics trend are unclear. Here for first time, we use an ensemble 10 tree ring‐width chronologies from west‐central margin to reconstruct detail variability back 1566 CE. reconstruction captures weak/strong events also...
Abstract Given growing concerns about global climate change, it is critical to understand both historical and current shifts in the hydroclimate, particularly regions critically entwined with circulation. The Tibetan Plateau, Earth’s largest highest plateau, a nexus for atmospheric processes, significantly influencing East Asian hydroclimate dynamics through synergy of Monsoon Westerlies. Yet, understanding recent fluctuations their wide-ranging ecological societal consequences remains...

Abstract Climate change has a large impact on vegetation dynamics. A series of statistical analyses were employed to demonstrate the relationship between Advanced Very High Resolution Radiometer (AVHRR) Global Inventory Modelling and Mapping Studies (GIMMS) Normalized Difference Vegetation Index (NDVI) data with an 8 × km resolution meteorological data, during period 1982–2005. Rainfall great varying time lags. The sensitivity NDVI threshold accumulated temperature varies regionally. To...
Abstract A nested coupled model has been developed to investigate the two‐way interactions between regional climate of eastern Africa and Lake Victoria. The atmospheric component is North Carolina State University (NCSU) version National Center for Atmospheric Research (NCAR) (NCSU‐RegCM2). lake based on Princeton ocean (POM). Three simulations, each 4 months long, have performed short rains September through December. control experiment standard NCSU‐RegCM2 a one‐dimensional second was...
Abstract Gross primary production (GPP) is an important variable in studies of the carbon cycle and climate change. The Moderate Resolution Imaging Spectroradiometer (MODIS)-GPP product (MOD17) provides global GPP data for terrestrial ecosystems; however, it not well validated China. In this study, eddy covariance (EC) system observed at 10 sites northern China was used to validate MOD17. results indicated that MOD17 presents a strong bias study region due meteorological data, MODIS FPAR...
Abstract The numerous temperature and precipitation reconstructions in China based on tree-ring-width data have played significant roles furthering the understanding of past climate changes. However, geographical variability responses trees to variations remains largely undetermined. Here, we describe an important spatial boundary response variations, namely 600-mm annual isoline. We found that, north this line, tree-ring widths are usually positively correlated with negatively...
Abstract A distinct greening trend is evident in Asia, especially on the Loess Plateau (LP) of China, which driven by climate change and large‐scale land‐use‐related ecological projects, 'Grain for Green Program' (GFGP). However, specific contributions GFGP to vegetation variation this a large spatiotemporal scale are not yet clear. We used long‐time‐series normalized difference index datasets based double mass curve method quantify projects LP. found that interannual fluctuation was likely...

The use of normalized difference vegetation index (NDVI) data acquired with multiple satellite sensors has become a necessity in research fields such as agriculture, land-use and land-cover change changes the natural environment, where fast are taking place. A good understanding these is strong requirement long-time-series monitoring programmes.

This paper presents an efficient alternating direction method with patch-based dictionary updating, ADMDU-DEB, for sparse representation regularization framework of image deblurring. The main idea the proposed is to reformulate variational problem as a linear equality constrained and then minimize its augmented Lagrangian function. decouples minimization by alternately iterating pixel-based representation. Typically, accelerated coding simple updating applied in stage enable whole algorithm...
The Qinghai-Tibet Highway (QTH) crosses 528 km of a permafrost region in the Plateau, half which has suffered freezing-thawing damage induced by sunny-shady slope effect (SSSE), especially Southern Tanglha Region (STR). Given this problem, continual field investigation was carried out STR to examine types and development characteristics affected embankments. indicated that up 60% featured an asymmetric specialty, mainly comprising uneven thaw deformation longitudinal cracks. Furthermore,...
