摘要
以无机氮作为污染控制因子,应用扩散数值模拟方程估算了三盘港投饵网箱养鱼的养殖容量。结果显示:三盘港海域水交换能力较强,但富营养化程度严重,其中网箱养殖对无机氮贡献率约占82%。按照目前的养殖布局,以网箱养殖对水体无机氮增量的影响小于0.049mg/L,即养殖区无机氮浓度值不超过0.400mg/L为标准,三盘港投饵网箱养殖容量约为2100口。
In this paper, numerical simulation value is used to estimate the carrying capacity of Sanpang Port with inorganic nitrogen as a pollution control factor. The results shows that： water exchange capability is powerful in Sanpan Port, but eutrophication is serious; cage culture of inorganic nitrogen contribution rate is about 82%. According to the present culturing layout, if inorganic nitrogen increase caused by cage culture is less than 0.049 mg /L, ie inorganic nitrogen concentration in culture zones is not more than 0.400 mg / L, the carrying capacity of Sanpan Port is about 2100.
