Tamarix austromongolica is endemic to the Yellow River Basin and has adapted diverse ecological settings in region, including arid areas of northwestern China saline soil regions Delta. However, genetic basis its local adaptation remains unclear. We report a chromosome-level assembly T. genome based on PacBio high-fidelity sequencing Hi-C technology. The 12 pseudochromosomes cover 98.44% 1.32 Gb assembly, with contig N50 52.57 Mb BUSCO score 98.2%. comprises 913.6 (68.83%) repetitive sequences 22,374 protein-coding genes. Genome evolution analyses suggest that genes under positive selection significantly expanded gene families have facilitated austromongolica's adaptability environmental factors high resistance diseases. Using genotyping-by-sequencing, we conducted population structure 114 samples from 15 sites. Two groups were identified, 289 candidate assigned populations eastern parts River, respectively. Furthermore, discovered numerous associated high-altitude salt tolerance. This research provides valuable genomic resources for evolutionary study breeding tamarisk.

The middle reaches of the Yellow River basin (MYRB) are among regions most severely affected by soil erosion globally. It has always held a pivotal role in and water conservation ecological restoration efforts China. Nonetheless, face recurrent drought occurrences growing human intervention, there have been notable alterations eco-environmental quality (EEQ) within MYRB. However, influences intervention on EEQ MYRB remain unclear. In this study, remote sensing index (RSEI) was applied to quantify spatiotemporal changes contributions land use type transitions from 1990 2022. results showed that fluctuated significantly exhibited weak overall improvement trend over past 33 years. proportion good excellent grades for improved, while poor fair decreased, especially northern regions. follows phased pattern. During periods 1990–2002 2011–2022, an improving is observed, period 2003–2010 shows no significant change EEQ. Drought had strongest influence 2003 2010, followed 2002, lesser impact 2011 primarily positively influenced spring, autumn winter droughts negatively summer droughts, arid grassland unused areas. improved during initial final phases projects, with drought. increase project implementation less noticeable, period.

Currently, research on traditional villages mainly focuses the current development status and evolutionary trends in specific regions, with relatively limited studies from a macroscopic holistic perspective spatiotemporal evolution of villages. Therefore, this study selects Yellow River Basin (YRB) as object. By analyzing distribution characteristics driving factors (TVs) basin, it aims to further promote high-quality YRB protect cultural resources. Based data 892 village points first sixth batches TVs YRB, ArcGIS 10.8 spatial analysis techniques were employed analyze overall pattern YRB. The results indicate: (1) In are more numerous east than west south north, forming clusters contiguous distributions, dense areas primarily upstream regions dominated by Qinghai Province midstream along Shanxi-Shaanxi coast. (2) number scale basin generally exhibit an increasing trend, imbalanced provincial distribution. More recent years show balanced proportions, higher mountainous plateau basin. (3) layout center within evolves each batch, showing migration north south, back finally west. (4) interaction natural social plays synergistic role TVs. Among these, geographical primary factors. commonly found low altitude sunny slopes, mild climate, abundant precipitation, proximity ancient roads rivers, gentle soil predominantly comprising loess, brown earth, alluvial soils. environment is secondary factor, often located larger populations, developed economies, rich heritage.

Abstract Soil erosion status is a comprehensive indicator reflecting the quality and stability of ecosystems. changes in China are becoming more unclear due to climate change intensified human activity. Within framework change, this study treats rainfall factor as dynamic examines three types contrasting precipitation—general, heavy, extreme—through integrates Revised Universal Loss Equation Geographic Information Systems reveal differences water driven by varying intensities precipitation. The results that over 63% China's land area has experienced soil during historical period (1980–2022), with slight being most common. Severe predominantly found Southwest Basin, Yangtze River Yellow basin. multi‐year average rate estimated at 2.46 t·ha −1 yr , R95P R99P contributing 26.50% 7.71%, respectively. Future projections (2023–2100) indicate PRCPTOT, R95P, could increase 22%–91% under SSP5‐RCP8.5 SSP2‐RCP4.5 scenarios. Overall, limited effect on spatial pattern China, mainly influencing intensity extent adversely impacting regions. Extreme precipitation sensitive making future risks associated it critical concern. These findings can guide decision‐makers resource managers regional planning enhance resilience secure food resources.

Vegetation, serving as the primary constituent of terrestrial ecosystems, plays a crucial role in regulating energy flow and material cycles providing vital resources for human socio-economic activities. This study analyzes spatio-temporal patterns economic density vegetation coverage Yellow River Basin (YRB) based on forest resource inventory data from 448 counties 2008, 2013, 2018. A three-tiered criterion layer is constructed using core explanatory variable, encompassing social development factors, land use natural factors. two-way fixed effects model then utilized to analyze impact coverage. Results reveal that: (1) Spatially, demonstrates “low west high east” pattern, with an overall upward trend YRB. Conversely, cover exhibits “high low displaying downward trend. (2) Over 2008–2018 period, significant negative correlation between observed each county YRB, decreasing by 1.108% every 1 unit increase density. Notably, upstream areas YRB experience coverage, while middle lower reaches witness decrease. (3) Considering control variables, proportion industry, urbanization rate, protection level, cultivated area exert influence across entire basin. Policymakers should formulate relevant policies achieve sustainable discussed proposed countermeasures. delineates practical pathway high-quality high-level ecological offering valuable reference analogous research other regions.
