| 中文摘要 |
| 受人类活动的影响,塔里木河干流水质盐化不断增加,有必要寻求一种快速简便的方法进行水质矿化度的监测。从已采集的100个不同类型水样所得到的分析结果看,其矿化度数值变化范围大,而且水化学类型多样。由于在本区域内水样的水化学类型随着电导率和矿化度的升高,其离子组成有一定的变化规律,因此将电导率测定数值划分成3个区间,进行电导率与矿化度的回归分析,同时考虑矿化度和水化学类型。水样的电导率与矿化度回归分析表明,在3个区间内所有回归方程式均在0.01水平上高度显着,并且电导率与矿化度密切相关。所以,在塔里木河干流区域可以用电导仪进行水样的电导率快速测定,然后用电导率进行矿化度的换算,其结果是可靠的。 |

| The analytical results of water samples in the main stream of Tarim River showed that the changeable range of mineralization is wide and chemical type of water is various. As chemical types of water existed change to some degree with degree of mineralization rising,after values of electric conductivity (Y) are divided into 3 intervals (0<Y<2mS·cm-1,2≤Y≤5mS·cm-1,5mS·cm-1<Y),the concentration of mineralization and chemical types of water were involved.The results of regression analysis to electric conductivity and mineralization showed that it is reliable for mineralization of water samples to be calculated with electric conductivity in studied area. |
