中文摘要:

      通过对艾比湖天然水体化学成分的分析,确定了水化学类型及平面分布特征,湖水属高矿化度,pH偏碱,溶解氧含量低。水化学类型为氯化盐钠组Ⅱ型,水体矿化度达202.2 g/L。还采用水质综合特征模式、综合营养指数法对湖水质及营养状况进行评价,得出艾比湖以劣五类水体为主,中度富营养化的评价结论,为艾比湖水资源保护和合理利用提供科学依据。

英文摘要:

      Hydrochemical type and plane distribution characteristic of Ebinur lake was determined by hydrochemical composition analysis.Ebinur lake water is of high salinity, meta-alkalescence and lacking dissolved oxygen.The hydrochemical type is type-II,group NaCl, and the salinity is as high as 202.2 g/L.Besides,water quality and nutrition status of the lake was evaluated through integrated model and trophic status indexes.It is concluded that the nutrition status of Ebinur lake is moderate and the water quality be...
