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.

High-resolution feature pyramid attention network for high spatial resolution images land-cover classification in arid oasis zones

International Journal of Remote Sensing, Год журнала: 2024, Номер 45(11), С. 3664 - 3688

Опубликована: Май 21, 2024

Land-cover classification based on remote sensing technology has been adopted for decision-making concerning agricultural development, urban planning, and ecosystem protection in arid oasis zones. The semantic segmentation method deep learning, as a new paradigm, can effectively overcome the limitations of traditional pixel-based object-based methods obtain good results from high spatial resolution (HSR) images. However, how to extract exact category boundary realize precision mapping is still problem. This paper proposes novel high-resolution feature pyramid attention network (HRFPANet) land-cover classification. It integrates advantages multi-scale extraction, mechanism, fusion alleviates inconsistency, roughness, fragmentation associated with previous models. experimental show that mIoU score HRFPANet 79.5%, which 11.5% 2.6% higher than PSPNet UPerNet, respectively. proves proposed model be used qualified Our source code available at https://github.com/HPU-CPD/HRFPANet.git.

Rational Maize–Soybean Strip Intercropping Planting System Improves Interspecific Relationships and Increases Crop Yield and Income in the China Hexi Oasis Irrigation Area

Agronomy, Год журнала: 2024, Номер 14(6), С. 1220 - 1220

Опубликована: Июнь 5, 2024

Abundant light and heat in the Hexi Oasis Irrigation Area China provide superior natural conditions for agricultural development. To study maize–soybean planting system of intercropping determine group yield economic benefits Area, eight treatments were set up 2022–2023: with a bandwidth 1.8 m row ratio 2:3 (M1S3), 2:4 (M1S4), 2.0 (M2S3), (M2S4), 2.2 (M3S3), (M3S4), monocropping maize (M), soybean (S). We analyzed effects changes bandwidth–row ratios on photosynthetic characteristics, yield, interspecific relationships these during two crop reproductive periods. Our results showed following: (1) Under system, capacity was highest when 2∶3 m. The net rate (Pn) increased by 1.72% to 48.90%, transpiration (Tr) 5.53% 118.10%, stomatal conductance (Gs) 2.82% 86.49% compared other systems. Increasing from improved characteristics soybean, increasing Pn, Tr, Gs 3.44% 74.21%, 3.92% 53.69%, 2.41% 55.22%, respectively. (2) under significantly higher than that intercropping. In treatments, average crops M3S3 16,519.4 kg ha−1, an increase 6.48% M3S4 indicating reduction one same increases yield; benefit over years 35,171.73 CNY which 13.3 80% monocropping, leads better farmers monocropping. (3) two-year experiment, land equivalent (LER) model, averaging 1.25 years, showing productivity (4) When 1.8, 2.0, or m, LER decreased 8.3, 5.9, 5.6% additional soybeans, relative crowding coefficient soybeans respective bandwidths 4.59, 4.72, 0.75%, competition (CRM) 22.94, 16.97, 12.74%, (CRS) 20.47, 17.61, 16.78%, competitive power greater rows would weaken advantage resulting reduction. 2:4, 3.31 0.86%, aggressiveness (AM) 7.55 12.50%, CRM 18.04 24.84%, CRS 17.32 22.77%, respectively, indicated different systems could improve thereby improving benefits. (5) AHP method, entropy weight TOPSIS analysis ranked first, comprehensive evaluation (0.6017). conclusion, can coordinate interspecies relationships, benefit, be used as suitable oasis irrigation area.
