摘要
[目的]明确博斯腾湖流域不同水体氢氧同位素特征差异.[方法]测定2014年博斯腾湖流域不同水体的氢氧同位素值,并与前人各期数据进行时空上的对比.[结果]湖水δ18O均值为-0.36‰,δD为-15.98‰,存在δD=2.99δ18O-14.91的数量关系;河水δ18O均值为-9.23‰,δD为-61.81‰,其关系:δD =6.10δ18O-5.43;地下水δ18O均值为-8.11‰,δD为-57.01‰,其关系:δD =4.61δ18O-19.68.经与Craig(1961)全球大气降水线(GMWL)及根据全球降水同位素观测网GNIP数据与乌鲁木齐大气降水线方程(LMWL)对比,地下水、湖水与河水氢氧同位素组成均大致落在当地大气降水线和全球大气降水线附近,显示受降水补给为主.与2001、2008、2011年数据对比显示,各年间各水体(地下水、地表水)氢氧同位素数据存在一定差异,该差异或由各期采样点空间分布不同引起.[结论]研究结果为博斯腾湖流域的可持续发展提供了理论依据.
Abstract
[Objective] The aim was to study characteristic difference of hydrogen and oxygen isotope in different water bodies of Bosten Lake Basin.[Method] The values of hydrogen and oxygen isotope in different water bodies in Bosten Lake Basin in 2014 were determined and compared with previous data from spatial and temporal layer.[Result] The lake water mean value of δ18O was-0.36‰,δD was-15.98‰,with relationship of δD =2.99δ18 O-14.91;the river water mean value of δD was about-61.81‰,δ18 O was-9.23‰,with relationship of δD =6.10δ18O-5.43;the groundwater mean of δ18O value was-8.11‰,δD was-57.01‰,with relationship ofδD =4.61δ18O-19.68.The datum of river water,lake water and groundwater were all distributed around the Graig(1961) global and local meteoric water line in δ18O-δD coordinate system,indicating the characteristic of precipitation water.Compared with data in 2001,2008 and 2011,there were some differences in various water bodies in different years,which may caused by different sampling points in each period.[Conclusion] The study provides theoretical basis for sustainable development of Bosten Lake Basin.
