C-N-P Conservation Model for the Coastal Environmental Assessment

Abstract

A marine environmental simulation is used to grope about the way of solving an environmental problem on the enclosed sea area. This technique including the ecosystem model, which details mainly the biological circulation of material, is evaluating the circulation quantity and the accumulation quantity, the ability of material to be purged away and so on quantitatively. The ecosystem model describes the material recycling of one piece of index material such as carbon, nitrogen, the phosphorus. Therefore, it is generally estimated that the other material circulates using the computed flux and the C-N-P ratio of the compartment. In this research, we point out that it isn't possible to do the correct evaluation using the conventional method, because the total amount of one piece of material is conserved but other materials are not saved. The C-N-P conservation model is proposed to keep total materials in ecosystem model.
