| 摘 要： | 首次对桑沟湾的海带养殖容量进行了调查研究。采用了无机氮作为估算桑沟湾海带养殖容量的关键因子，通过无机氮的供需平衡估算海带养殖容量。结果显示，海底沉积物中释放的无机氮为该湾无机氮的主要来源，而由海水交换所带入的无机氮次之。海带生长期间海水交换周期为３９ｄ，比８０年代中期延长了近１倍。桑沟湾在海带生长期间由海水交换、陆地径流、动物排泄和海底沉积物中释放所进入该湾的无机氮总供应量为１２２８ｔ；而浮游植物

| Abstract: | By budgeting the supply and demand quantity of inorganic nitrogen, the Carrying capacity of Sanggou Bay for the culture of kelp Laminaria japonica. was studied from July, 1993 to December, 1994. Results showed that (1) sea water exchange period of the bay in 1994 was about 39 days,almost one fold longer than thatmiddle of 80's; (2)the nitrogen released from the sediment of sea bed was the biggest supplier of inorganic nitrogen for the bay; (3)the total amount of inorganic nitrogen available in the bay was 1228 MT,and among them,about 664 MT was available for supporting the growth of kelp ; (4) the total carrying capacity of Sanggou Bay for culture of kelp was about 54 000 MT sun-dried weight,or about 600kg/1 500m2 in average for unit area carrying capacity. |
