The Shule River Basin, a typical arid inland river basin, faces critical water scarcity that threatens ecological security and sustainable development. This study integrated the FLUS and InVEST models to simulate water yield in 2030 and 2050 under three climate scenarios (SSP119, SSP245, SSP585). Geographic detectors quantified the driving mechanisms of natural and human factors. Results showed: (1) Desert dominates land use (78.6% in 2020). Under SSP119, desert area decreases by 0.69% by 2050, while under SSP585 it expands by 5.7%, with grassland loss of 23.0%, indicating severe ecological degradation. (2) Water yield exhibits a south-high, north-low spatial pattern, with high values in glacier-covered and high-altitude areas. SSP119 yields the most significant increase (147.6×10^8 t by 2050), whereas SSP585 shows minimal increase (43.9×10^8 t) due to extreme climate. (3) Precipitation and DEM are core driving factors; the interaction between land use type and precipitation has the strongest influence, implying that artificial land use changes can significantly regulate water yield. This multi-scenario framework provides decision support for water resource management and ecological governance in arid inland river basins.

Aqueous zinc-iodine (Zn-I2) batteries are promising for large-scale energy storage due to their intrinsic safety, low cost, and high theoretical capacity (211 mAh g−1 for iodine). However, their practical application is hindered by the poor electronic conductivity of iodine, sluggish redox kinetics, and the shuttle effect of polyiodides. This review systematically analyzes the reaction mechanisms of iodine cathodes, including two-electron (I−/I2) and multi-electron (I−/I2/I+ and I−/I2/I+/IO3−) pathways, and identifies key bottlenecks. It then comprehensively summarizes recent advances in iodine host materials, categorized into three strategies: physical confinement, chemical adsorption, and electrocatalysis. Representative host materials such as porous carbons, covalent organic frameworks (COFs), porous aromatic frameworks (PAFs), polymers, MXenes, and Prussian blue analogs (PBAs) are discussed, with emphasis on the structure–performance relationships. The review highlights that heteroatom doping (e.g., nitrogen) enhances chemical adsorption of iodine species, while single-atom catalysts (e.g., Co, Zn) provide electrocatalytic sites that accelerate conversion kinetics. Finally, future research directions are proposed, including exploration of multi-electron systems, mechanistic elucidation of iodine conversion, development of advanced host materials, and optimization of zinc anodes, to accelerate the commercialization of Zn-I2 batteries.
