【摘要】 根据1998年4月至1999年2月对厦门西海域网箱养殖区底层海水中NH3 N、NO2-的含量变化规律的分析,结合环境因子水温(t)、DO、pH、COD等对发生在养殖底层海水中的氮的硝化作用进行了分析。结果表明,网箱养殖区底层水N的正常代谢偶联,是养殖水体保持稳定的重要条件。更多还原

【Abstract】 Based on monitoring data from Aug.1998～Feb.1999 in marine cultured cage from western Xiamen sea,the variation of NH3N,NO2-, relationships among NH3N,NO2- and enviornmental key parameters (t,DO,pH) were disscussed .Nitration also was analysed. The result shown that metabolism coupling of nitrogen is the basis of selfpurification ability in the bottomwater and to keep it stable in marinecagecultured.更多还原
