摘要
于2015年10月28~29日,在黄河三角洲国家级自然保护区内的清水沟和清八汊河口,分别采集芦苇(Phragmites australis)盐沼、盐地碱蓬(Suaeda salsa)盐沼和柽柳(Tamarix chinensis)盐沼表层(0~10 cm深度)土壤样品,测定了土样中17种金属(V、Cr、Co、Ni、Cu、Zn、Ga、Pb、Sr、Mn、Ti、Na、Mg、K、Fe、Ca、Al)的含量,并对两个河口土壤中的各元素含量进行了比较。研究结果表明,在清八汊和清水沟河口表层土壤中,与其它金属元素含量相比,Co质量比都相对最小,分别为7.97 mg/kg和8.35 mg/kg;Al质量比都相对最大,分别为86664.06 mg/kg和102319.51 mg/kg;除Na外,清水沟河口表层土壤中的其它金属元素(V、Cr、Co、Ni、Cu、Zn、Ga、Sr、Pb、Mg、Al、K、Ca、Ti、Mn、Fe)含量都高于清八汊河口;在清八汊河口,芦苇盐沼表层土壤中的各金属元素含量较高,而在清水沟河口,柽柳盐沼表层土壤中的各金属元素含量较高;在清八汊河口,表层土壤中Mg含量与Co、Ni、Zn、Ga、Pb、Al、Ca、Mn和Fe含量显著正相关,在清水沟河口,表层土壤中Co含量与Ni、Cu、Zn、Ga、Pb、Mg、Al、K、Ca、Mn和Fe含量显著正相关,说明这些金属元素可能具有同源性。
Soil samples(0-10 cm depth)of Phragmites australis salt marsh,Suaeda salsa salt marsh and Tamarix chinensis salt marsh were collected in Qingbacha and Qingshuigou estuaries of the Yellow River Delta National Nature Reserve on 28-29 October,2015.The contents of the metals including V,Cr,Co,Ni,Cu,Zn,Ga,Pb,Sr,Mn,Ti,Na,Mg,K,Fe,Ca and Al were determined to study the metal distribution characteristics,and contents of the metals in the surface soils were compared in the two estuaries.The results showed that the contents of Co in surface soil were the lowest in Qingbacha and Qingshuigou estuaries compared with other metal elements,with the values of 7.97 mg/kg and 8.35 mg/kg,respectively.The contents of Al were the highest in surface soil both in the two estuary,with the values of 86664.06 mg/kg and 102319.51 mg/kg.Except for Na,the contents of metals in surface soil were higher in Qingshuigou estuary than those in Qingbacha estuary.The other metal contents were higher in surface soil of Phragmites australis salt marsh in Qingbacha estuary and in surface soil of Tamarix chinensis salt marsh in Qingshuigou estuary.There were significantly positive correlations between contents of Mg,Co,Ni,Zn,Ga,Pb,Al,Ca,Mn and Fe in surface soil of Qingbacha estuary,and contents of Co,Ni,Cu,Zn,Ga,Pb,Mg,Al,K,Ca,Mn and Fe in surface soil of Qingshuigou estuary,which suggested that the metals were homologous.
