The successful launch of Landsat-9 marks a significant achievement in preserving the data legacy and ensuring continuity Landsat’s calibrated Earth observations. This study comprehensively assesses reflectance Normalized Difference Vegetation Index (NDVI) between Landsat-8 Operational Land Imagers (OLIs) over diverse Chinese landscapes. It reveals that sensor discrepancies minimally impact NDVI consistency. Although Landsat-9’s top-of-atmosphere (TOA) is slightly lower than Landsat-8, small root-mean-square errors (RMSEs) ranging from 0.0102 to 0.0248 for VNIR SWIR bands (and larger RMSE at 0.0422) fall within acceptable ranges observation applications. Applying atmospheric corrections markedly enhances uniformity brings regression slopes closer unity. Further, Bidirectional Reflectance Distribution Function (BRDF) adjustments improve comparability, measurement reliability, maintains robust consistency across various types, time series, land cover classes. These findings affirm success achieving Landsat program, allowing interchangeable use OLI purposes. Future research may explore specific correlations different vegetation types seasons while integrating complementary platforms, such as Sentinel-2, enhance understanding factors.

ABSTRACT As one of the carbon neutralization or reduction strategies, constructing large hydroelectric dams leads to formation fluctuating backwater zones (FBZs). Synchronization water and sediment under impacts climatic changes human activities over FBZs is still an open question due diverse particularities zones. Taking FBZ world's largest power station, that is, Three Gorges Reservoir (TGR), as a typical example, we attempt address such in this study. Based on analyses water‐sediment characteristics, relationships, covariations, Budyko hypothesis attribution decomposition method are coupled quantitatively examine synchronization. Modeling results reveal construction cascade reservoirs dominates decrease load (e.g., 73.9% for Jialing River basin from 1985 2020), alteration runoff‐sediment relationships across FBZ. The dominator (accounting 46.01%) increasing annual average runoffs upstream wetting climate, while (64.14%) decreasing ones tributary activities; by contrast, play dominant roles (from 72.1% 98.1%) loads These findings provide scientific support addressing water‐sediment‐related issues navigational safety, deposition, environment worldwide FBZs.

The Hotan River, the sole river traversing Taklimakan Desert in northwest China, sustains a critical desert riparian ecosystem dominated by Populus euphratica. This habitat is integral to biodiversity maintenance. However, global climate change and anthropogenic disturbances have profoundly impacted landscape, leading fragmentation reduced environmental heterogeneity. Consequently, there has been notable decline P. euphratica populations. study aimed assess physiological resilience of under harsh conditions analyze vegetation distribution patterns along zone. Laboratory tests were employed determine indexes including Relative Water Content (RWC), Chlorophyll (Chl), Soluble Sugar (SS), Free Proline (Pro), Peroxidase Activity (POD) euphratica, providing insights into its capacity endure challenging conditions.
