The evaporation of soil water drives the upward movement salt and its accumulation on surface, which ultimately leads to salinization in agroecosystems. With rapid development remote sensing technology, transport can be monitored accurately. Based Landsat 8 satellite imagery ERA5-Land reanalysis datasets, this study explored variation characteristics northeast Tibetan Plateau from 2013 2023, inferred by geostatistical methods like ridge regression, windowed cross correlation, machine learning algorithms. results show that negative correlation effect between deep moisture (100–289 cm) is stronger. Moreover, also have a time lag compared with instant responses, meaning caused may require longer times. As potential driving factors, an increase organic carbon runoff beneficial for alleviating while abundant promotes humidification. This has elucidated specific regulation within different profiles, understanding ecological balance

Exploring the influencing factors of potential evapotranspiration (PET) is great significance for further understanding causes climate change and improving agricultural irrigation efficiency. In this study, modified Mann–Kendall analysis was used to elucidate temporal variation characteristics meteorological PET based on a dataset from 710 stations in China. Furthermore, we revealed main that influence heterogeneity by combining sensitivity with contribution method. The results showed 1) exhibited trend changes yearly scale, slope ranges temperature (T), relative humidity (RH), net radiation (RN), wind speed (U) 0.03–0.04 °C/a, 0.03–0.08 %/a, 0.001–0.007[MJ/(m2/day)]/a, −0.005 −0.012(m/s)/a −0.30–0.38 mm/a, respectively. 2) coefficient fluctuated greatly inter-annually, but more pronounced inter-annually. Most sensitive factor RN hyperarid (HAR), arid (AR) semiarid regions (SAR), while it changed RH semihumid (SHR) humid (HR). dry relatively wet hot seasons, during cold seasons. 3) were determined coefficient, significant observed. HAR, AR, SAR SHR, T U result higher contributions. HR, primarily caused its RN. 4) region humid-cold bigger drivers affecting changes, arid-hot they strong nonlinear relationship between factors. This finding holds scientific evolution mechanism under changing environments.

Mechanism controlling groundwater chemistry in the hyper-arid basin with intermittent river flow: insights from long-term observations (2001–2023) in the lower Heihe River, Northwest China

The geochemical processes of groundwater in arid regions are generally influenced by both natural hydrological and human activities. However, impacts water-rock interactions on recharge via processes, controlled intermittent river water flow withdrawals, is still poorly understood. In this study, 327 chemistry datasets collected from the upper, middle (including Gobi riparian zones), lower Ejina Delta Northwest China 2001 to 2023 were analyzed. Our results revealed that total dissolved solids ( TDS ) concentration ranged approximately 881.5 ± 331.6 mg/L upper 1,953.6 1,208.5 regions, with an increasing trend observed. Ecological conveyance EWC ), recharging aquifer through flow, resulted a decrease concentrations mainly region. While irrigation notably affected region, resulting substantial increase salinity. Groundwater Middle region remained relatively stable over study period. Generally, hydrochemical composition shifted Na-Mg-SO 4 -HCO 3 Na-Mg-Ca-SO types -Cl Na-SO predominant Gobi. These shifts likely be attributed interplay interactions, coupled evaporation-crystallization processes. Inverse modeling using PHREEQC upper-middle primary involved calcite dissolution precipitation dolomite, gypsum, halite, sylvite salts, as well cation exchange reactions (2NaX+Ca 2+ →CaX 2 +2Na + ). contrast, hydrogeological system middle-lower exhibited opposite pattern interactions. Overall, ecological partially facilitated during lateral while disrupted hydrogeochemical equilibrium, involving halite compared other regions.
