| 摘 要： | 以内蒙古乌梁素海为研究对象,对其在冰封过程中富营养化指标在冰体和水体中的浓度及分布特征及其在乌梁素海的空间变异性进行分析,得出冰封期乌梁素海富营养化状况。其中,乌梁素海水体中的富营养化指标含量均大于对应的冰体中的含量,主要指标COD、总氮、总磷在水体中的含量均值分别是冰体中含量均值的1.65、1.61和1.78倍;水体中的营养盐变异性明显小于冰体中的。说明低温冷冻过程对水体中污染物有一定浓缩效应,并对此进行了解释,以期为乌梁素海富营养化治理提出研究方向。

| Abstract: | With Wuliangsu Lake as a research object,the concentration of eutrophication indexes in the ice and water and their spatial variability in Wuliangsu Lake were analyzed,which concluded that Wuliangsu Lake was eutrophic during the icebound period.The eutrophic index in water was larger than that in ice.The contents of COD,TN and TP in water were 1.65,1.61 and 1.78 times that in ice.The residual nutrient variability in water was smaller than that in ice,indicating that the cryopreservation process had certain concentration effect on pollutants in water.The study proposed a research direction for the eutrophication treatment of Wuliangsu Lake. |
