Groundwater plays a leading role in ecological environment protection semi-arid regions. The Huangshui River Basin is located the Tibetan Plateau and Loess transition zone of areas. Its relatively fragile, there an urgent need for systematic study basin to develop groundwater realize rational efficient development water resources. In this study, methodologically, we combined following: 1. Field sampling (271 samples across basin’s hydrogeological units); 2. Comprehensive laboratory analysis major ions physicochemical parameters; 3. Multivariate statistical (Pearson correlation, descriptive statistics); 4. Geospatial techniques (ArcGIS kriging interpolation); 5. Hydrochemical modeling (Piper diagrams, Gibbs plots, PHREEQC simulations). Key findings reveal generally weakly alkaline (pH 6.94–8.91) with TDS ranging 155–10,387 mg/L; Clear spatial trends: (Na+, Ca2+, Mg2+, Cl−, SO42−) increase along flow paths; Water types evolve from Ca-HCO3-dominant (upper reaches) complex Ca-SO4/Ca-Cl mixtures (lower reaches); Water–rock interactions dominate hydrochemical evolution, secondary cation exchange effects; identifies dominant carbonate dissolution (mean SIcalcite = −0.32) localized evaporite influences (SIgypsum up 0.12). By combining theoretical calculations experimental results, reveals distinct patterns evolution mechanisms. transitions Ca-HCO3-type upstream areas Ca-SO4/Cl downstream, driven primarily by gypsum minerals. Total dissolved solids dramatically paths (155–10,387 mg/L), Na+ SO42− showing strongest correlation mineralization (r > 0.9). Cation processes anthropogenic inputs further modify chemistry midstream These establish baseline sustainable management ecologically vulnerable basin.

Spatial reconstruction and scenario simulation of historical processes future trends land use/cover change (LUCC) can help to reveal the background conversion spatial distribution land. Moreover, there is a close relationship between spatiotemporal dynamics changes in different ecosystem services (ESs). Using this simulate use scenarios important. In study, an LUCC dynamic analysis framework (LSTM-PLUS-FMOP) was constructed based on deep learning time series forecasting model (LSTM), parallelized urban (PLUS) fuzzy multiobjective programming (FMOP) model. The PLUS used analyze driving mechanism expansion explore pattern. addition, three were established: natural (NLE), economic development priority (EDP) regional sustainable (RSD). FMOP ES perform conversion. uncertainty parameters treated by intuitionistic numbers (IFSs). This study applied Yellow River Basin Shaanxi Province (YRB-SX). results showed that (1) from 2000 2020, cropland area YRB-SX continuously decreased 12.67 × 104 ha, while built-up increased 28.25 ha. net reduction woodland grassland 13.90 (2) relative error range prediction using LSTM 0.0003– 0.0042. had better accuracy than Markov chain (3) 0.26% 0.85% 1.68% (RSD) under scenarios. 25.01%, 32.76% 14.72%, respectively.

Abstract The Ebinur Lake Basin is an ecologically sensitive area in arid region. Investigating its land use and cover (LULC) change assessing predicting ecosystem service value (ESV) are of great importance for the stability basin's socioeconomic development sustainable ecological environment. Based on LULC data from 1990, 2000, 2010, 2020, we assessed ESV coupled grey multi-objective optimization model with patch generation simulation to predict changes 2035 under four scenarios: business-as-usual (BAU) development, rapid economic (RED), protection (ELP), ecological–economic balance (EEB). results show that 1990 basin was dominated by grassland (51.23%) unused (27.6%), a continuous decrease increase cultivated land. In thirty years, total study increased 18.62 billion 67.28 yuan, regulation support services being dominant functions. By 2035, while decreased all scenarios compared 2020. BAU, RED, ELP, EEB 68.83 billion, 64.47 67.99 66.79 respectively. RED scenarios, 2.81 0.49 BAU scenario, provisioning 6.05% 2.93%, ELP focusing environmental protection, saw services. This paper can assist policymakers optimizing allocation provide scientific formulation strategies inland river basins regions.

The serious problem of soil erosion not only has a profound impact on people’s lives but also results in series ecological and environmental challenges. To determine the changes land use type urban agglomeration northern slopes Tianshan Mountains, this study commences by employing InVEST-SDR (integrated valuation ecosystem services tradeoffs–sediment delivery ratio) model to calculate levels spanning from 2000 2020. Subsequently, it forecasts cover (LULC) conditions for year 2030 under three scenarios: Q1 (natural development), Q2 (ecological protection), Q3 (economic priority). This projection is accomplished through integration coupled Markov chain multi-objective planning (MOP) alongside patch-generating simulation (PLUS) models. Ultimately, based these outcomes, predicts 2030. There been consistent decline 2020 with high-intensity concentrated Mountain region. Grasslands, glaciers, permafrost are identified as most erosion-prone types area, forests exhibiting highest capacity retention. Converting grassland barren forest within same area substantial reduction erosion, specifically 27.3% 46.3%, respectively. Furthermore, transformation leads noteworthy 19% decrease erosion. Over past two decades, witnessed significant grasslands, notable shift towards impervious surfaces due economic development mining activities. predicted scenarios depict expansion land, grassland, Soil decreases different shared socio-economic pathway (SSP) relative an increase scenario scenario, whereas amount exhibits continued when effect change considered. Persistently rapid can exacerbate problems, underscoring need find balance between growth conservation. As slows down, greater emphasis should be placed protection maintain stability.
