dc.description.abstract本文利用15n-nH4+氧化法对湄洲湾近岸水体的硝化作用进行深入研究。结果表明,湄洲湾近岸水体硝化速率范围在0.51~4.60μMOl·l-1·d-1。养殖区附近较高的硝化速率,有利于海水对nH4+-n污染物的自净作用,当水体硝化作用强烈时,水中的nO-3的浓度也随之升高,表明海水中nO-3主要来自于细菌的硝化作用。湄洲湾海水nH4+-n的周转时间在1~9 d,表层水体的nH4+-n转化时间高于底层水。硝化作用转化nH4+为nO-2,并最终转化为nO-3,减少了nH3-n及nH4+-n对近岸养殖系统中生物的危害。
dc.description.abstractThese studies were conducted to estimate nitrification in coastal water of Meizhou Bay by [15N]ammonium oxidation method.The nitrification rate of 0.51 ~ 4.60 μmol·L-1·d-1were recorded,and the higher nitrification rate in water close to aquaculture area were propitious to ammonium self-purification.Higher nitrification rate was observed at high NO-3concentration water column,which showed NO-3 produced mostly from nitrification.The biological turnover times for NH+4 were short( 1 ~ 9 d) in coastal water of Meizhou Bay with the longer turnover times in surface seawater.Nitrification transformed NH+4 to NO-2,final to NO-3,reducing the harm to organisms of coastal aquaculture system resulted from NH3-N and NH+4-N.
