利用Sr Ba、B、K/Na和磷酸盐等方法对吐哈盆地西南缘水西沟群存款的古水环境进行了预测。结果表明，水西沟群时期为淡水环境，Sr/Ba <1，B含量为12.30 ~ 64.20ppm，古盐度为2.28‰（J1 B）~ 2.23‰（J1 x），平均2.07‰。本文还讨论了恢复沉积环境古盐度的其他方法，并指出了它们的局限性。
The paleoaqueous environment of Shuixigou group deposit in southwestern margin of Turpan-Hami basin is predicted by using Sr-Ba, B, K/Na and phosphate methods. The results show the fresh-water environment in the period of Shuixigou group with Sr/Ba ratio of less than 1 and B content ranging from 12.30ppm to 64.20ppm, and paleosalinity from 2.28‰ of J1b to 2.23‰ of J1x, averaging 2.07‰. Also, the other methods to recover paleosalinity in sedimentary environment are discussed and their limitations are presented in this paper.
