As natural isotope tracers, δ 18 O and 2 H have been widely applied to examine the water uptake of plant root, but various stable mixing models may lead different explanations. To understand influence models, here we selected a typical Caragana korshinskii Kom. in northeastern Tibetan Plateau, analyzed compositions xylem potential sources including precipitation soil water. Three i.e., IsoSource, MixSIR MixSIAR were used, then differences proportional contributions for root examined. The...
Abstract Different water sources exploited for public use have different exposure to risks associated with climatic and environmental change. Isotope ratios of tap previously been studied as a potential tool link supply waters source characteristics at local continental scales, providing information on the footprint used. Work that combines intensive spatial temporal sampling independent management data has limited, however. In this study, an extensive observation network was established...
Abstract The ecohydrological separation hypothesis has generated considerable scientific interest and debate in studies, it assumes there exist two water pools subsurface water, one of which is soil used by plants the other that supplied to groundwater. Although this been tested several humid sites, a further test arid semiarid conditions still needed. Based on isotopic ratios different bodies collected during 2‐year field work, was drier zone located Qilian Mountains northeastern Tibetan...
Although stable isotopes of hydrogen and oxygen in surface waters (especially river waters) are useful tools to understand regional hydrological processes, relevant information at some upper reaches large rivers western China is still limited. During 2016–2017, we focused on the Liujiaxia Reservoir along Yellow River, where collected water samples two locations, above below dam (identified as “lake water” “river water”). The results show that heavy lake enriched during warm months, when...
(1) Background: The degree to which local precipitation is supplied by recycled moisture a reflection of land surface–atmosphere interactions and potentially significant climate feedback mechanism. This study tries figure out the water cycle mechanism at mountainous region then provides reference for similar regions outside China. (2) Methods: dual-isotopes Bayes-based program MixSIAR used assess contributions advected, transpirated evaporated vapor precipitation. (3) Results: average...
Hydrological processes produce effects on water resources in inland mountainous regions. To perform a comprehensive investigation of the important segments cycle, using Qilian Mountains as case study, precipitation, soil, plant, river, and groundwater were collected during plant growing season 2016. All samples monthly basis, except which was per event basis. The results showed that: “temperature effect” apparent, suggested drier climate background; there differences slope intercept local...
The origin of bottled water can be identified via its stable isotope signature because the spatial variation composition natural waters. In this paper, pattern δ2H and δ18O values were analyzed for a total 242 samples produced at 137 sites across China that randomly purchased during 2014–2015. isotopic ratios vary between −166‰ −19‰ δ2H, −21.6‰ −2.1‰ δ18O. Based on multiple regression analyses using meteorological geographical parameters, an isoscape Chinese was created. results showed...
As plant species for riparian ecological restoration in northern China, Tamarix ramosissima and Salix matsudana play an important role river protection, flood control, regional climate regulation, landscape construction of vegetation. Two sampling sites were selected the zones along Lanzhou section Yellow River, where xylems potential water sources collected. The direct comparison method, Bayesian mixture model MixSIAR proportional similarity index (PS index) used to determine proportions...
With the frequent occurrence of marine dangerous chemicals accidents, it is particularly important to assess environmental risk hazardous chemicals. In paper, a qualitative assessment method summarized by analyzing research status at home and abroad in recent years. The mainly applicable low-risk
It is of great significance to study the influence evaporation on protection and management regional water resources. In this study, samples have been collected from a typical enclosed body, Liuxi, small brook in campus Suzhou University May June, then analyzed for their hydrogen oxygen stable isotopes. The results indicate that June higher d18O dD values relative May, both them plotted at right meteoric line, combination with lower deuterium excess (d-excess) implying has influenced by...
