摘要
研究结果表明,辽宁省海岸带沉积物中的化学成分主要是以RCO_3、Fe_2O_3、MgO、CaO、MnO、C_(ong)和N_t的形式存在。这些化学成分的含量与沉积物类型的关系十分密切。它们的分布受控于沉积物来源、物源区岩石的化学成分、底质物化条件、河口区絮凝作用,以及沉积物中生物活动等因素。沉积物中的CaO与RCO_3、MgO与Fe_2O_2、N_t、与C_(org)之间分别存在着良好的相关关系。
Results of the study show that chemical constitution in sediment from the coastal zone of Liaoning Province exists mainly as RCO3, Fe2O3, MgO, CaO, MnO, Corg and Nt. The contents of those chemicals are in good connection with sediment types. Their distribution is affected by sources of the sediment, chemical constituents of the rocks in material original areas, physical and chemical conditions in the sediment environment, agglutination in estuaries, and living thing's activities in the sediment, etc. There is a good relativity respectively between CaO and RCO3, MgO and Fe2O3, and N, and Corg in the sediment.
