The Hubao–Egyu Urban Agglomeration (HBEY) was a crucial ecological barrier in northern China. To accurately assess the impact of climate change on vegetation growth, it is essential to consider effects time lag and accumulation. In this study, we used newly proposed kernel Normalized Difference Vegetation Index (kNDVI) as metric for condition, employed partial correlation analysis ascertain accumulation period response by considering different scenarios (No/Lag/Acc/LagAcc) various combinations. Moreover, further modified traditional residual model. results are follows: (1) From 2000 2022, HBEY experienced extensive persistent greening, with kNDVI slope 0.0163/decade. Precipitation identified dominant climatic factor influencing dynamics. (2) HBEY, effect temperature most distinct, particularly affecting cropland grassland. precipitation pronounced (3) Incorporating into models increases explanatory power impacts dynamics 6.95% compared models. Our findings hold implications regional regulation research.

Woody plants serve as crucial ecological barriers surrounding oases in arid and semi-arid regions, playing a vital role maintaining the stability supporting sustainable development of oases. However, their sparse distribution makes significant challenges accurately mapping spatial extent using medium-resolution remote sensing imagery. In this study, we utilized high-resolution Gaofen (GF-2) Landsat 5/7/8 satellite images to quantify relationship between vegetation growth groundwater table depths (GTD) typical inland river basin from 1988 2021. Our findings are follows: (1) Based on D-LinkNet model, woody was extracted with an overall accuracy (OA) 96.06%. (2) Approximately 95.33% desert areas had fractional plant coverage (FWC) values less than 10%. (3) The difference cover proved be fine indicator for delineating range desert-oasis ecotone. (4) optimal GTD Haloxylon ammodendron Tamarix ramosissima determined 5.51 m 3.36 m, respectively. Understanding is essential effective conservation water resource management regions.

ABSTRACT Interbasin water diversion project has been considered as an effective way to assure resource system sustainability. In order assess the impacts of on sustainability, we propose a framework in terms reliability, resilience, and vulnerability. The estimated availability from hydrological models projected demand are input allocation model. model allocates two available sources (i.e., local diverted water) water‐receiving areas. differences allocated resources between these figured out quantify area Bailong River Water Diversion Project, located Gansu, China, was selected case study. results show that compared reference planning years, runoff future years will be reduced, while their demands almost increase under all scenarios. Although current designed scheme is increasing there still potential for resilience through optimizing scheme. Further, more unfavorable supply conditions are, larger space This study can help understand sustainability changing environment.

The Weining Plain is in the semi-arid northwest region of China, with groundwater as its main source for various purposes. This research provided a detailed investigation into exploitation status Plain, analyzed quality different purposes, and estimated recharges using water budget analysis end member mixing analysis. entropy index was applied to assess overall drinking water, industrial several agricultural indicators were used assessment uses. findings showed that recharge area primarily comes from irrigation infiltration leakage canal system which account approximately 50–60% total recharge. poor, over 80% being moderate poor requiring treatment. A large proportion suitable irrigation. However, has corrosive effect on boilers, there high risk boiler scaling foaming. Only 12.41% samples have good use, treatment uses needed. study can help local decision-makers understand availability resources manage reasonably.
