The arid region of Northwest China (ARNC) is responsive to global climate change, and drought events have occurred frequently in recent decades. However, studies about the effect meteorological stress on vegetation change ARNC are still insufficient. In this study, we analyzed spatiotemporal trends factors (temperature, TMP; precipitation, PRE; standardized precipitation evapotranspiration index, SPEI), (vapor pressure deficit, VPD; soil moisture, SM), (normalized difference NDVI) during 1982–2021. We also investigated characteristics by run theory, including times, duration, severity, intensity. impacts were explored using Pearson correlation analysis structural equation model (SEM). found that annual growing season TMP, PRE, VPD, SM, NDVI showed an increasing trend contrast, SPEI exhibited a decreasing season. addition, varied significantly ARNC. primarily Tarim River Basin, Turpan-Hami Hexi Corridor. SEM results consistently demonstrated TMP SM exerted greater growth than SPEI. determine PRE. Exploration influence essential for comprehending dominant change.

Soil salinization is a prevalent global issue, significantly impacting crop cultivation and food production. This study investigates the potential of sustainably harnessing rainwater for remediation saline soils in water-scarce regions. column leaching experiments were performed to evaluate effectiveness different methods salt removal from tillage layer. The findings demonstrated that intermittent was more effective than continuous remediating NaCl-type soils. When with 27 cm applied, soil layers below 5 ranged 12.28% 26.86%. Intermittent increased rate between 44.49% 54.18%. higher desalination efficiency attributable extended soil–water contact time. time 1.5 h over 4.5 h, comparable effects produced. similar patterns Na2SO4-type However, due stronger affinity SO42− clay particles, their effluent concentration lower Cl− under same conditions. To optimize efficiency, operational parameters can be adjusted reduce depth 15 cm, interval events 24 h. this may serve as valuable reference restoration improvement efforts
