中文摘要在系统采集贡嘎山海螺沟水样的基础上,综合运用描述性统计、相关性分析、Gibbs图、阴阳离子三角图和主成分分析法,对水化学主离子特征及其控制因素进行了分析。结果表明:Ca2+和HCO3-分别平均占阳、阴离子总量的78.63%和67.28%;源头区总溶解固体含量(TDS)与雨水的含量相当,全流域TDS平均值为128.36 mg/L;海螺沟流域水化学类型为Ca2+—HCO3-。在源头区,由于冰雪融水对径流量补给量较大,大气降水的输入作用对源头区水体化学离子的组成具有一定的影响。从全流域看,岩石的化学风化是海螺沟水化学主离子来源的主要控制因素,蒸发-结晶和大气降水的作用影响较小。而碳酸盐岩的风化则是海螺沟流域岩石风化的主要类型。
英文摘要To analyze the major ion chemistry of water in Hailuogou catchment and possible controls, 18 group of water
samples were collected and tools including the descriptive statistics, the correlation matrices,Gibbs Figure,Triangular
diagrams of anions and cations,and the Principal Composition Analysis were employed. The results show that
the contents of Ca2 + and HCO -
3 account for 78. 63% and 67. 28% of cations and anions, respectively. In the headwater
region, the content of TDS ( Total Dissolved Soilds) is approximately equal to that contained in rain water.
The average value of TDS in Hailuogou catchment is 128. 36 mg /L. The hydrochemical type of Hailuogou catchment
is Ca2 +—HCO -
3 . The composition of ion in headwaters region is influenced partly by atmospheric deposition
because the ice and snow melting water is an important water source of headwaters catchment. For whole catchment,
the major ion chemistry of river water is controlled by carbonate weathering,while the effect of evaporationcrystallization
and atmospheric deposition is low.
