摘要:
以海域无机氮(N)和无机磷(P)输入与吸收的平衡原理，通过2000~2001年对厦门大嶝岛海域海水交换、沉积物释放、陆地和江河径流排放、养殖动物和野生海洋动物排泄等项无机氮和无机磷输入量的调查、检测，浮游植物、潮滩微型藻类、野生大型藻类、养殖和野生海洋动物对无机氮和无机磷吸收量的调查和检测，估算可供养殖海带和紫菜的无机氮和无机磷数量，进一步以海带和紫菜有机氮和有机磷的含量，来衡量海带和紫菜的可养殖量。估算结果表明，无机氮平衡法估算大嶝海域紫菜和海带养殖容量(淡干品)分别为5.43×104和32.84×104 t，单位面积可养密度分别为7.21和43.61 t·hm-2。无机磷平衡法估算大嶝海域紫菜和海带养殖容量分别为1.97×104和12.22×104t，单位面积可养密度分别为2.62和16.23 t·hm-2。模型的实用性分析以无机磷供需平衡法为佳。
Abstract:This paper use the balancing principle of input and output of inorganic nitrogen and inorganic phosphorus, based on the investigation and detection of the input quantity of inorganic nitrogen and inorganic phosphorus from seawater exchange, release of sediment, runoff of land and river, excretion of ocean animals in Dadeng Island sea area from 2000 to 2001.By investigating and detecting the input quantity of inorganic nitrogen and inorganic phosphorus from phytoplankton, algae, the quantity of inorganic nitrogen and inorganic phosphorus left for Porphyra and Laminaria were estimated, and then the carrying capacity of Porphyra and Laminaria were estimated by calculating the concentration of organic nitrogen and phosphorus. The result shows that in Dadeng Island sea area the carrying capacity of Porphyra and Laminaria estimated by inorganic nitrogen equity are 5.43×104 and 32.84×104 t, the density of unit area for culture are 7.21 and 43.61 t·hm-2, respectively. The carrying capacity of Porphyra and Laminaria estimated by inorganic phosphorus equity are 1.97×104 and 12.22×104t, the density of unit area for culture are 2.62 and 16.23 t·hm-2, respectively.
