The sea environment digitize is very importance to the sea science researching and economy,the sea environmental monitoring is the main practice method and basis of the sea environment digitize.

This paper describes and discusses the selection and design of the subsea effluent pipeline diffuser based on National laws and standards of sea environmental protection and taking a newly established subsea effluent pipeline diffuser in Daya Bay for example.

Through calculating the discharge quantity of nitrogen (N) and phosphorus (P) from each cage, and taking the maximum restriction values of N and P for eutrophication as control values, a mathematical model is employed to simulate the restriction of marine environment of the Gongwan Bay on the capacity of cage-culture.
