哑铃湾网箱养殖环境容量研究 Ⅱ.网箱养殖环境容量计算

Research on environmental capacity of cage culture in Yaling Gulf Ⅱ.Calculation of environmental capacity of cage culture

根据作者自己建立的网箱养殖污染负荷模型,结合二维水动力和水质数学模型,对哑铃湾网箱养殖环境容量进行了计算。结果表明,随着养殖时间的增加,该海域养殖容量不断地变小,当预计只养1a时,它的容量为5 410 0箱,10a以后,它的容量就变为3 45 0 0箱。而目前该海域只有40 0 0箱左右的网箱,还远远没有达到它的环境限制容量。

On the basis of the pollution load model for the cage culture established by author, the calculation on the environmental capacity for aquaculture was made, combining with two-dimension hydropower model and water quality mathematical model. The result shows that the environmental capacity for aquaculture diminishes with culture time . It is expected that the capacity would be 54100 boxes when the culture time is 1 year and after 10 years, 34500 boxes. At present, there are only 4000 boxes in the area, which doesn't reach the environmental capacity.
