摘　　要：研究了大型海藻羊栖菜的增养殖对允泊湾大型海塘水环境因子的影响，发现羊栖菜对餐厨废水中N、P有明显的吸收效果。2011年2～4月羊栖菜的增养殖期间，试验鱼排区海域的COD含量从140．3mg／L下降到65．7mg／L，减少53．2％；NH4＋ -N含量从0．72mg／L下降到0．53mg／L，减少26．4％；P含量从0．35mg／L下降到0．17mg／L，减少51．4％；叶绿素a含量随时间的变化不明显。试验结果表明大型海藻的增养殖对降低近海海水富营养化有重要的作用。The effect of Hizikiafusiforme multiplication on marine environment factors of large seawall on coastal waters in Yunbo Bay was studied. The result showed that Hizikiafusiforme was suit for uptaking N and P. In the aquaculture period of Hizikiafusiforme during Feb. to Apr. 2011, COD of fillet area was decreased from 140.3 mg/L to 65.7 mg/L, by 53.2%; NH4＋ -N was decreased from 0.72 mg/L to 0.53 rag/L, by 26.4%; Phosphorus was decreased from 0.35 mg/L to 0.17 rag/L, by 51.4%, variation of chlorophyll was not obvious, which indicated that Hizikiafusiforme played an important role in eutrophication of coastal waters.
