| 摘要: |
| 根据于1989年5-6月和1990年5-8月对可可西里地区综合科学考察所得资料，采用常规化学分析法、利用ICP-3520光谱测定仪分析研究该地区湖泊及其补给水系的化学成分和展布规律。结果表明，其主要化学组分在水体演化中呈累积增长，阴、阳离子的比值对水体属性有很大的影响，补给水系的化学组分与流域内的地球表生作用存在密切关系；揭示出研究区水体微量化学元素展布的基本态势和B-Li等具协同性元素对属性，以及Sr-Ba，As-Hg等具对抗性元素对属性。境内主要湖区水体组分的动态变化与气候环境事件有一定的关系。 |

| Abstract: |
| Data obtained in May to June, 1989 and May to August, 1990, in a comprehensive scientific expedition were used to systematically analyses the chemical composition and the dispersal law of the lakes and the water supply system in the Kekexili region by using conventional chemical analysis and ICP-3520 spectrum detem1ination. The results were as follows: the accumulation and growth of the main chemical components of the water body during its evolution showed that the cation / anion ratio had great impact on the water body properties, and that there were close relations between the chemical composition of the water supply system and the geohypergenesis of the drainage area where the trace chemical elements are dispersed basinwide in the water body at a certain ratio for the coordinative element couple B-Li and another certain ratio for the antagonistic element couples Sr-Ba, As-Hg. etc. The author analyzed the main influencing factors for these, and the variation of the main lakes’ water body composition with climatic environment events. |
