养殖水环境中氮的循环与平衡

Cycle and Budget Balance of Nitrogen in the Cultivated Water

养殖水环境中 ,由于人为的介入和影响 ,使得水体中氮的各种形态转化和循环过程发生了改变。笔者详细地介绍了养殖水环境中氮的各种存在形态 ,及其相互之间的转化和循环过程 ,同时总结了前人研究和提出的各种养殖水环境中氮的物质平衡模型 。

Because of human's intervention and influence,the transformation and cycle of the nitrogen is greatly changed in the cultivated water.Inthis article,we discuss the forms of nitrogen in cultivated water,and depict the transformation and cycle among the various forms of the nitrogen in detail.At the same time,we sum up all kinds of budget models of nitrogen,which have given by the predecessors,and provide the scientific warranties for optimizing the aquaculture and protecting the aquatic environment.
