摘　　要：对低温时期查干湖水体的水化学特征进行分析和研究。从布设在查干湖湖面的11个采样点的监测结果可知,低温时期,查干湖的pH为8.39～10.09,总硬度为40.03～71.28mg/L,矿化度为444.93～1 149.32mg/L;湖水中的阴离子以HCO3-为主,占阴离子总量的60.67%～82.13%,阳离子以Na+为主,占阳离子总量的83.52%～86.69%,其水化学类型为重碳酸盐钠组I型。查干湖所处地理位置、气候条件以及水文情况,导致查干湖矿化度较高。The hydrochemical characteristic of Chagan Lake at low temperature period is researched and analyzed in this paper. The results from 11 sampling points over Chagan Lake showed that the pH is from 8. 39 to 10.09, the hardness is from 40. 03 mg/L to 71.28 rng/L, the mineralization degree is from 444. 93 mg/L to 1 149.32 mg/L. The main anion in lake is HCO3- , accounting for 60.67%-82.13% of total anions. The main cation in lake is Na＋ , accounting for 83.52%-86.69% of total cations. The hydrochemical type of Chagan Lake is Bicarbonate-Na-I. Due to its location, climate and hydrology, Chagan Lake has high mineralization.
