摘    要:本文对1989年5月和8月采集的黄河口附近浅海表层沉积物及柱状沉积物进行了磷酸盐形态(吸附态磷、铝磷、铁磷、闭蓄态磷和钙磷)的分析,并对几个样品的不同粒级也分别作了形态分析。结果表明,钙磷占无机磷的大部分;闭蓄态磷次之;铝磷和吸附态磷再次之;铁磷含量极微。除钙磷(由于有矿物磷的存在)在粉砂粒级中含量最高外,其它各形态磷的含量均随粒度变细而增高。

关 键 词:黄河口  沉积物  无机磷酸盐  粒度

Abstract:Different inorganic phosphorus forms (Ads-P, A1-P, Obs-P and Ca-P) of surface and core sediments taken from the area near the Huanghe River Estuary in May and August, 1989 were analysed. Some of them were fractionated into sand, silt and clay before phosphorus form analyses. Ca-P was found to be the major component of the total inorganic phosphorus, Obs-P the second, Al-P and Ads-P the third. Fe-P existed in minor quantities. Except that the Ca-P content was highest in the silt fraction due to the existen.ce there of mineral apatite, the contents of all other forms increased with decreasing sample particle size.
Keywords:Huanghe River Estuary  Sediment  Inorganic phosphorus  Forms  Particle size
