摘　　要：研究了三都澳网箱养殖海域沉积物中总磷(TP)及P的5种不同形态的分布特征,探讨了这些P的形态分布与水产养殖之间的相互关系.结果表明,表层沉积物中TP含量为(243.57～722.73)×10-6,其中无机磷(IP)含量在(217.36～609.94)×10-6,占TP的66.8%～89.2%,有机磷(OP)含量在(6.20～113.92)×10-6,占TP的10.8%～33.2%.TP及各形态P含量的高值都出现在青山岛和斗帽岛之间、三都岛南岸及礁头-城澳北岸等大黄鱼养殖海域,低值出现在非养殖区,显示养殖活动对底质P的形态分布已有明显影响.The distribution characteristics of total phosphorus and the five species of phosphorus in the sediments from the cage maricuhure areas of Sandu Bay were investigated. The rdationship between the distribution of species of phosphorus and aquaculture were discussed. The results showed that the contents of total phosphorus in the surface sediments ranges from 243.57 × 10^-6 to 722.73 × 10^-6, and that of inorganic phosphorus from 217.36 ×10^-6 to 609.94 ×10^-6, to be 66.8 % ～89.2 % of total phosphorus. The contents of organic phosphorus from 26.20 × 10.6 to 113.92 ×10^-6, to be 10.8% ～ 33.2% of total phosphorus. The higher contents of total phosphorus and five forms of phosphorus appeared to be in the mariculture areas of Pseudosciaena Crocea, which are between Qinshang Island and Doumao Island, south of Sandu island and north coast of Jiaotou-Cheng＇ ao, while the lower contents appeared to be in the non-maficulture areas. It shows that the distribution of species of phosphorus were significantly effected by the marieulture activities.
