摘要
根据2003年7月对虾工厂化养成后期水体的实测数据,分析了台风发生期间不同养殖水体三氮的周日动态及其与环境因子的关系。结果表明:在该养殖生态系统中,台风气候对三氮的含量影响较大,硝化作用受阻明显,转化率较低,与环境因子之间的关系差异显著,尤以密度大的养殖池最为明显;但对三氮的日变化动态影响不大,变化幅度较小。
Effects of typhoon on nitrogen levels were studied in water from industrialized white legged shrimp （Litopenaeu vannamei） cultivation during later period in July of 2003. The results showed that the contents of nitrogen was affected significantly by the typhoon and the nitrification was reduced with low conversion efficiency in the ecological system of the cultivation. The daily variation in nitrogen levels, however, was not found to be changed significantly with small fluctuation.
