“…The d‐excess of precipitation is primarily governed by the relative humidity of air mass at its origin and is virtually independent of atmospheric processes (T. Wang, Chen, & Li, ; Wassenaar, Athanasopoulos, & Hendry, ). Evaporation from continental surface water bodies at low humidity can produce vapour mass with high d‐excess (M. X. Yang, Yao, Wang, Tian, & Gou, ; Zhan et al, ). Recently, Jouzel et al (Welker, ) discussed in detail the variation in d‐excess of precipitation and its relevance to oceanic sources of precipitation (Warrier et al, ).…”

“…The stable isotopes HDO, H 2 18 O, and H 2 16 O have been widely used as environmental tracers in hydrology, especially for precipitation, surface water, and soil solution (Anderson & Downing, ; Wen et al, ; Zhan, Chen, & Zhang, ). Being the basic components of water, hydrogen (H) and oxygen (O) can be used to identify the origins of different water bodies within the water cycle as well as to understand their interactions (Zhan et al, ). Due to their complex origins, the isotopic composition of water sources typically exhibits significant differences.…”

In order to better understand isotopic characteristics of eco‐hydrologic processes in subtropical zones, this study selected a typical subtropical watershed in China to investigate and determine the complex differential mechanisms inherent to this water body type. Results showed that stable isotopes in precipitation within a Local Meteoric Water Line in the Xiangxi River basin (where δD = (8.23 ± 0.27)δ18O + (17.97 ± 1.65); R2 = 0.94) weighted δD and δ18O average precipitation values were −22.11‰ and −5.23‰, respectively. Furthermore, enrichment trends in river water δ18O (−4.21‰ to −6.91‰) and δD (−25.11‰ to −38.13‰) and soil solution δ18O (−6.30‰ to −11.21‰) and δD (−11.21‰ to −34.57‰) were greater compared with precipitation δ18O (−0.23‰ to −12.06‰) and δD (0.54‰ to −98.52‰) and throughfall δ18O (−1.11‰ to −4.72‰) and δD (−2.11‰ to −24.95‰). This study found obvious seasonality and higher deuterium excess (d‐excess) values in precipitation during the dry season and lower values during the rainy season. Moreover, the orchard was more enriched and the coniferous and broad‐leaved mixed forest was more depleted in δD and δ18O compared with other land cover types. Precipitation was an important climate variable in subtropical watersheds under the influence of monsoon systems. According to results from the isotopic mixture model, precipitation input fractions were greater than 88% in the soil solution and greater than 21% in river water.

“…Scholars have studied stable isotope characteristics of different types of water bodies as well as hydrological processes in some watersheds (Liu et al 2019;Zhan et al 2016;Wu et al 2010), plateaus Qiu et al 2019), basins (Ahmed and Diab 2018;Robertson and Sharp 2013) and glaciers (Rai et al 2019;Jeelani et al 2017). For example, by investigating the spatial and temporal characteristics of δD and δ 18 O, Zhan et al (2016) studied the local hydrological processes in Dongting Lake and sorted out the interactions between precipitation, river water, lake water and ground water. Liu et al (2019) studied the isotope characteristics of hydrogen and oxygen in different water bodies in the Lhasa River basin and pointed that there are mutual recharge relationships between ground water, river water and springs.…”

As the main bodies of water transformation, precipitation, soil water, plant water, river water and ground water play important roles in water cycle. Based on stable isotope values of five types of water bodies collected in the subalpine shrubland of the eastern Qilian Mountains from May to October in 2019, the characteristics of hydrogen and oxygen isotopes and their differences of different water bodies were studied. The results showed that the slope of the local meteorological water line (LMWL) was lower (7.63 < 8) and the intercept was higher (14.06 > 10) than those of the global meteorological water line (GMWL), indicating that the precipitation isotopes were enriched by evaporative fractionation. Stable isotope values of soil water mainly recharged by precipitation vary significantly and seasonally (summer > autumn > spring) and decreased with increasing of soil depth, where there were some differences in different aspects. Plant transpiration was more intense than evaporations of other water bodies, thus stable isotope values of plant water were the highest among five water bodies. There were differences in stable isotope values among plant species at different stages in growing season (germination and leaf development stage > flowering and fruiting stage > leaf drop decline stage), and those of plant water were higher on semi-shady slopes than on semi-sunny slopes. Stable isotope values of tributary streams were higher than those of main streams, and there were seasonal differences between them (main streams: autumn > spring > summer, tributaries: autumn > summer > spring). Among five types of water bodies, the fluctuation variation of stable isotope values was the greatest in precipitation and the smallest in ground water. This study can help to improve the understanding of ecohydrological processes in subalpine shrubland and provide a reference basis for the ecological management in the Qilian Mountains and the rational utilization of water resources in the Shiyang River Basin.
