| 摘 要： | 以东平湖表层沉积物为研究对象,研究了东平湖表层沉积物理化特性分布特征。结果表明,东平湖沉积物pH值为7.80～8.26,属于中性偏碱性水质,而电导率和阳离子交换量的变化与水质情况有密切联系。东平湖沉积物有机质平均含量为29 mg/g,湖泊表层沉积物以粉砂质为主,对沉积物中营养元素的吸附以及迁移的影响较大。湖泊TN和TP含量的平均值为938.12、806.5 mg/kg,TP平均含量比TN低约17.8%,且两者不存在显著相关性,表明东平湖沉积物中的氮和磷具有非同源性。

| Abstract: | Taking Dongping lake superficial sediments as study object,the physical-chemical properties and distribution characteristics of nitrogen and phosphorus in surficial sediment of Dongping Lake were analyzed.Results showed that the pH value of superficial sediment was neutral to alkaline,and there were significant relationships among water quality and cation exchange capacity(CEC),as well as electrical conductivity(EC) in Dongping Lake.The average contents of OM were 2.9% and the main superficial sediments wer... |
