以胶州湾表层及柱状沉积物为研究对象,利用连续提取法,研究了沉积物中各形态P的含量、地球化学分布特征、控制因素及环境意义,并对比分析了连续提取法与单步提取法的数据。结果表明,IP是胶州湾沉积物中P的主要形态,占TP的69.8%～81.9%,OP只占较小的比例;IP中Ca-P和Fe-P所占比例相对较大,是沉积物中P的主要赋存形态,Fe-P、ACa-P、DAP占TP的比例分别为21.3%～39.1%、6.2%～20.1%、22.1%～40.1%;P的含量及垂向分布受其来源、人类活动以及粒度、浮游植物量、pH、温度、盐度等环境因子的影响。
Taking the surface layer and columnar sediment of Jiaozhou Bay as the research object, the content of each form P, geochemical distribution, controlling factors and environmental significance of sediment were studied by continuous extraction method. The continuous extraction method and single step extraction Law data. The results showed that IP was the main form of P in the sediments of Jiaozhou Bay, accounting for 69.8% -81.9% of TP and only a small proportion of OP. The proportion of Ca-P and Fe-P in IP was relatively large, The main forms of P in the species were Fe, P, ACa-P and DAP, accounting for 21.3% -39.1%, 6.2% -20.1% and 22.1% -40.1%, respectively. The content and vertical distribution of P Its source, human activities and the effects of environmental factors such as grain size, phytoplankton quantity, pH, temperature, salinity and so on.
