| 摘 要： | 应用淡水沉积物的标准测试程序(SMT)测定了三峡水库湖北段长江干流和4条支流中14个采样点沉积物的总磷、无机磷、有机磷、铁/铝磷和钙磷的含量并对不同形态磷之间进行了相关性分析.结果表明,三峡水库湖北段水体表层沉积物中TP和各种磷的赋存形态存在明显的空间差异,TP含量为361.6～1033.5mg/kg;In-P是沉积物...

| Abstract: | Total phosphorus(TP),inorganic phosphorus(In-P),organic phosphorus(OP),Fe/Al-bound phosphorus(Fe/Al-P) and Ca-bound phosphorus(Ca-P) in surface sediment of 14 samples of main trunk of the Yangtze River and 4 anabranches in the Three Gorges Reservoir in Hubei were measured by the standard measurement and test(SMT) procedure of phosphorus forms in freshwater sediments.Correlation coefficients between phosphorus forms were also analyzed.In the study area,TP in surface layer deposit was 361.6~1 033.5 mg/kg.In-P... |
