| 摘 要： | 通过内蒙古乌梁素海表层沉积物和深层沉积物的研究分析,对乌梁素海的湖泊沉积物特征有着明确的了解。乌梁素海深层沉积物中各元素与河套平原深层土壤中基本一致,而表层沉积物中各元素则具有明显的特征。湖泊表层沉积物中主要富集C、lCd、S、F、Sb、C、B、iAs、Li、MgO、CaO、Cu、N、iSn、W、Zn、Co、Mo、Au、Sc、Tl、Hg、I、Mn、U、Ce、La、Be、Se、Th等。湖泊表层沉积物与深层沉积物相比,在表层富集S、orgC、N、Se、I、Br、Sr、C、U、Mo、C、lCaO、Hg、P。在湖泊表层富集上述元素说明了黏土极易吸附这些元素,有些元素的富集主要是由于人类活动造成的结果。同时在表层土壤中pH明显低于深层土壤和河套地区土壤的pH,这与工业排放等人类活动紧密相关。垂直剖面结果也表明,人类活动对湖泊环境造成了严重影响。乌梁素海已出现富营养化和Hg、F污染,需对其进行治理。 |

| Abstract: | Through the elemental analysis in sediments from the surface and deep layers of Wuliangsuhai Lake,the better understanding for sediment characteristics of the Wuliangsuhai Lake is gained.The element distribution in sediments from the deep layer of the Lake is basically identical with that from the deep soils in Hetao area and the distinct characteristics of element distribution in the surface sediments of the Lake are observed.It is discovered that elements of Cl,Cd,S,F,Sb,C,Bi,As,Li,MgO,CaO,Cu,Ni,Sn,W,Zn,Co,Mo,Au,Sc,Tl,Hg,I,Mn,U,Ce,La,Be,Se,Th,etc.are enriched in surface layer of the sediments.Compared with deep layer of the sediments,S,orgC,N,Se,I,Br,Sr,C,U,Mo,Cl,CaO,Hg and P are in abundant in surface layer of the sediments.It is explained that clay in surface layer of the sediments has strong trend to adsorb these elements and the enrichment of some elements has correlation with human activities.The value of the pH in the surface layer of the sediments is lower than that in deep layer and in soils in Hetao area,which is assumed to originate from industrial discharge.The vertical section chart also indicates that the human activities have serious influence on environment of Wuliangsuhai Lake.The eutrophication and pollution from Hg and F have appeared and serious attention should be paid to the environment pollution in this area. |
