中文摘要:

      运用灰色关联分析法对影响西台吉乃尔盐湖矿区地下卤水化学组分变化的主要因素进行分析,结果表明,各因素影响力大小的综合排序为TDS〉相对密度〉水位〉pH值〉卤水温度〉采卤量。内部因素（如TDS、相对密度）仍然是影响卤水化学组分变化的主要原因,但外部因素的影响（如水位变化）则越来越凸显其重要性。采卤量的影响力最小,说明在整个矿区范围内当前的采卤活动还没有对地下卤水化学组分的变化产生明显影响。

英文摘要:

      The main factors which influence the changes of chemical components in underground brine at mining area of Xitaijinair salt lake are analyzed by the method of grey degree of correlation. The results show that the influence order of factors is TDS, relative density, level of underground brine, pH value,brine temperature and collected brine quantity. The inner factor (such as TDS, relative density and pH value) are still the main factors which cause the changes of components in brine, but the factors (such as level of underground brine, etc. ) are playing more and more important roles. The collected brine quantity lying at the end of the order reveals that heretofore, in the whole mining area, the activities of collecting brine don't obviously cause the changes of chemical components in underground brine.
