| 摘 要： | 对西藏纳木错东部湖区中不同点位的湖水和周边不同位置的入湖河流进行取样,水化学分析结果表明:在主要阴阳离子组成中,Na+和Ca2+分别是湖水和河水的主要阳离子,分别占其阳离子总量的72.4%和71.9%.而湖水和河水的主要阴离子都是Hco3-,分别占其阴离子总量的71.9%和91.2%.从水化学的控制影响因素来看,纳木错湖水主要受蒸发-结晶作用控制,而河水则主要受岩石风化作用影响,其中碳酸盐和硅酸盐的风化影响最为重要,其次是部分蒸发岩的溶解,而区域内湖水蒸发与大气海盐传输也有一定的贡献. |

| Abstract: | Water samples were taken in different sites of eastern Nam Lake,Tibet,as well as in the inflowing rivers located in different positions around the lake.The results of water chemistry analysis indicating that among the major cation and anion composition,Na+ and Ca2+ were the main cations of lake water and river water,occupying 72.4% and 71.9% of the total cations respectively.While for both lake water and river water,HCO-3 was the main anion with the proportion of 71.9% and 91.2% of the total anions respecti... |
