Understanding vegetation’s drought response helps predict ecosystem adaptations to climate change and offers scientific insights for managing extreme events. Using RS technology, this study systematically investigates the mechanisms of vegetation their spatiotemporal variations in ecologically sensitive semi-arid area national grain security zone—West Liao River Basin, China. The findings reveal that (1) from 2000 2018, NDVI exhibited a fluctuating upward trend, trends remained pronounced certain areas seasons; (2) growing-season droughts impaired productivity, while winter reduced soil moisture, with arid-zone being most vulnerable; (3) grasslands responded rapidly drought, forests slowly via deep roots, croplands suffered during critical growth phases; (4) drought-adapted western forests/shrubs recovered best, eastern required targeted measures like resilient crops water management. results not only provide basis ecological management West Basin but also offer valuable resource other arid regions globally. This research holds significant importance addressing achieving regional sustainable development.

Central Asia is an ecologically fragile arid zone and a typical mixed salt‒sand region. The socioeconomic ecological problems attributed to the shrinking of Aral Sea in are notable concerns within international community. In this study, characteristics salt dust aerosols from were analysed explore their interannual variation analyse spatial temporal distributions sources transport dispersion pathways. results revealed that high concentrations concentrated around Lake Sarekamesh. range intensity less than those aerosols. Salt events occurred frequently spring autumn winter. occurrence frequency impact 2008 2012 significantly lower during previous period. From 2013 2018, originated largely on western side North Sea. autocorrelation was characterized by significant agglomeration, with changes cold spot hotspot regions. region affects mainly Kazakhstan spring, it more notably Russia study increase understanding variability lay foundation for impacts climate system environment zones.

“Production–Living–Ecological” spatial conflicts (PLECs) are critical issues arising from regional land development, affecting economic, social, and ecological security. Identifying analyzing these conflicts’ spatiotemporal characteristics is essential for sustainable development. This study focuses on the Tuha region, which experiences an extremely arid climate, classifying region’s (PLE) spaces into four types: living–production, ecological–production, production–ecological, spaces. A conflict measurement model based landscape patterns was developed to analyze evolution of PLECs 2000 2020. Additionally, PLUS used simulate PLEC in 2030 under different development scenarios. The results indicate that between 2020, area proportions region ranked largest smallest as follows: space, ecological–production production–ecological living–production space. space increased, while first increased then stabilized, areas decreased. From were predominantly characterized by mild weak conflicts. High–high clusters concentrated urban surrounding Gaochang District, Toksun County, Shanshan Yizhou low–low found Eastern Tianshan Mountains northern Barkol Kazakh Autonomous County. NDVI, GDP, population, proximity roads positively influenced PLECs, elevation, slope, aspect, precipitation had inhibitory effects. Under scenarios, natural scenario leads most severe conflicts, cropland protection reduces enhances welfare, making it optimal pathway future
