This study measured temporal spatial variability quality, as reflected remote sensing indices (RSEI), examined responses to connectivity (RNC). In total, 8 RNC indices, including structure density (Dr), water surface ratio (Wr), edge-node (β), (γ), node importance betweenness centrality (BC), PageRank (PG_R), out_degree (Out_D), in_closeness (In_C), were generated at...

Objectives Geriatric hip fractures, known as osteoporotic are associated with nutritional deficiencies such vitamin D (VitD). However, the relationship between other vitamins besides VitD and fracture is still lacking. Therefore, we intended to identify various levels in elderly patients fractures compared those healthy individuals. Methods A total of 210 geriatric continuous 402 individuals aged ≥65 years old complete serum records were enrolled this study. The VitA, VitB1, VitB2, VitB3,...

The Central and North Deborah gold deposits are located in one of 15 mining centers the Bendigo field, central Victoria, Australia, a major world-class province developed turbidite terrane. Gold mineralization occurs primarily within domes reverse-fault systems multiply deformed Lower Ordovician metaturbidites. Deformation thrusting occurred between 450 420 Ma coevally with regional metamorphism at zeolite to greenschist facies. In six stages quartz veining, each characteristic geometry...

Abstract. During the Asian summer monsoon season, prevailing southeasterly–southwesterly winds are subject to delivering air pollutants from North China Plain (NCP) northeast and northwest China. In present study, WRF-CHEM model is used evaluate contributions of trans-boundary transport NCP emissions quality in during a persistent pollution episode 22 28 May 2015. The generally performs well capturing observed temporal variation spatial distribution fine particulate matter (PM2.5), ozone...

Land surface temperature (LST) is a vital physical parameter in geoscience research and plays prominent role atmosphere interaction. Due to technical restrictions, the spatiotemporal resolution of satellite remote sensing LST data relatively low, which limits potential applications these data. An downscaling algorithm can effectively alleviate this problem endow with more spatial details. Considering nonstationarity, algorithms have been gradually developed from least square models...

Thermokarst lakes are a ubiquitous and important landscape feature in cold regions changing tremendously due to the accelerated climate change. In thermokarst lakes, sediment water two distinct but highly interconnected habitats, harboring different bacterial communities terms of taxonomic composition. However, co-occurrence networks these remain unclear. Here, we investigate ecological for Yellow River Source Area on Qinghai-Tibet Plateau. The results show that construct water....

Socioeconomic development often leads to environmental pollution and degradation initially while, beyond a certain point, there is the potential for improvements in quality. In this study, we conducted comprehensive review of published literature national data investigate changes nutrient concentrations limitations Poyang Lake from 1978 2021. Our objective was examine relationships between these process socioeconomic watershed. The findings revealed rapid Watershed, showing significant...

Thermokarst lakes are important aquatic ecosystems in cold regions, experiencing several changes due to global warming. However, the fundamental assembly mechanisms of microeukaryotic communities thermokarst unknown. In this study, we examined processes and co-occurrence networks sediment water Yellow River Source Area. Sediment had a significantly lower α-diversity but higher β-diversity than communities. pH, organic carbon, total phosphorus affected taxonomic phylogenetic diversity...

Hani terraced paddy fields are one of the most important ways for agricultural products and greatly influence regional landscapes in mountainous areas Southwestern China. However, knowledge soil nutrient conditions from is limited. This paper investigates such parameters as organic matter (OM), total nitrogen (TN), phosphorus (TP), available (AP), potassium (TK), (AK) four sampling sites under special geographical environment technology, compares differences nutrients related to spatial...

Accurate prediction of soil organic carbon (SOC) at fine scales is frequently limited by data availability but fine-scale maps properties are often great importance for local agricultural land management and watershed processes assessment. Terrain attributes derived from elevation have been commonly used predictor variables in SOC mapping. The aim this study to map density (0–30 cm) using hybrid methods that combine regional topographic models a residual kriging procedure samples an area...

Intensifying anthropogenic disturbances have caused water pollution in China recent decades. has a vast territory with diverse climate conditions, land use types, and human activities, leading to significant quality variability. However, few studies investigated nationwide spatiotemporal patterns of key parameters. In this study, we analyze monthly observations from 3647 gauge stations understand how changes over time space China. We group the by resource regions adopt Python SPSS...

More attention was paid to the excessive expansion of macrophytes which would accelerate bioaccumulation and terrestrilization. Studies on relationship between occurrence plant spread environmental variables are important because they provide understanding impacts natural human factors terrestrilization in wetland ecosystem.
