“…The spring flow in the Badain Jaran Desert recorded by is likely to be maintained by palaeowater rather than modern snowmelt. Radiocarbon data are required to confirm the hydrogeological model implied by isotopic data, but analogous results from a series study in Arid Northern China , the Minqin Basin (Zhang et al 2000;Ma et al 2005;Edmunds et al 2006), the Ejina area (Wu et al 2001) and Zhangye Basin (Zhang et al 2005) confirmed that the deeper groundwaters have late Pleistocene ages except where recharged by modern river runoff.…”

“…Some reasonable allocation and utilization plans have been proposed. Study of the hydrochemistry (especially isotopic geochemistry) of water resources is rather sparse and past work on the arid area has dealt largely with the chemical properties of the water, although there are several investigations on the interaction and mechanism between surface water, groundwater and rock in particular areas in recent years Feng et al 2004;Zhang et al 2005;Edmunds et al 2006). However, it is short of the regional understand of the groundwater recharge and chemical evolution, the volume of water available in the aquifer is not known and its rate of recharge, if any, is very uncertain.…”

“…The results showed that the moisture for most of precipitation events came from the southeast monsoon area of China and South Asia. Furthermore, stable isotope data have been used to study the recharge, origin, and mean residence time of groundwater in the Heihe River Basin (Zhang 2005;Chen et al 2006). However, no comprehensive studies have been undertaken for the spatial and temporal variation of isotopes in precipitation.…”

An intensive investigation of the spatial and temporal variations of dD and d 18 O in precipitation was conducted during 2002-2004 in six sites in the Heihe River Basin, Northwestern China. The dD and d 18 O values for 301 precipitation samples ranged from ?59 to -254 and ?6.5 to -33.4%, respectively. The relationship between dD and d 18 O defines a well-constrained line given by dD ¼ 7:82d 18 O þ 7:63, which is nearly identical to the meteoric water line in the Northern China. This wide range indicates that stable isotopes in precipitation were primarily controlled by different condensation mechanisms as a function of air temperature and varying sources of moisture. The results of backward trajectory of each precipitation day at Xishui show that the moisture of the precipitation in cold season (October-March) mainly originated from the west while the moisture source was more complicated in warm season (April-September). The simulation of seasonal d 18 O variation shows that the stable isotope composition of precipitation tended to a clear sinewave seasonal variation. The spatial variation of d 18 O shows that the weighted average d 18 O values decreases with the increasing altitude of sampling sites. The great difference of air temperature which led to the differences of condensation mechanisms and local recycled continental moisture may have influence upon the isotopic composition of rain events in different sites.

For example, Feng et al (2004) investigated the distribution and evolution of water chemistry in the Heihe River Basin and concluded that, since the 1960s large volumes of river water diverted for irrigation have re-emerged as springs at the edge of alluvial fans and then flowed into the Heihe River.…”

The impacts of environmental flow controls on the water table and chemistry of groundwater in the Ejina Delta, an arid inland river basin in northwest China, were investigated with field observations in 2001 and 2009. The results indicate that the shallow groundwater level rose by 0-2 m in the upper reaches of the east tributary of the Heihe River and in the areas of Saihantaolai-Dalaikubu during the period of environmental flow controls. The chemical constituents of the groundwater show a distinct spatial heterogeneity with the total dissolved solids (TDS) in the groundwater increasing from the periphery towards the depocenter of the Ejina Basin. In addition, the rate of groundwater cycling in the south of the Ejina Delta increased, and the mineralization of groundwater declined, while the overall mineralization and salinity increased in the northern regions, especially in the depocenter of the Ejina Basin. Since shallow groundwater is important to the ecology of arid regions, and because understanding the changes in the shallow groundwater environment (groundwater level and hydrochemistry) in response to environmental flow controls is essential for the sustainable improvement of the ecological environment, the results of this paper can be used as a reference for watershed water resources planning and management to help maintain the health and proper function of rivers in arid regions.
