本文通过对流沙湾和营盘珍珠养殖区初级生产力和野生滤食性动物现存量等的调查、马氏珠母贝的有机碳含量和滤水效率等的测定,应用营养动态模型和沿岸能流模型计算贝类生产量,并扣除野生滤食性动物现存量来计算贝类养殖容量,再通过食物限制性指标法进行检验。测定的结果如下:流沙湾和营盘珍珠养殖区马氏珠母贝的养殖容量较为接近,每公顷的容量分别为2142.6kg(含壳重)、10.3×104ind和2310.0kg(含壳重)、11.1×104ind。对营盘珍珠养殖区进行食物限制性指标分析的结果看,由以上2种模型得出的养殖容量不会对生态系统构成显著性压力,适合作为养殖容量的参照标准。
Based on the investigation of the primary productivity and the existing stock of wild filter feeders, the organic carbon content and the filtration efficiency of the pearl oyster in Liansha Bay and Yingpan pearl culture areas, the nutrition dynamic model and the coastal energy flow model were used to calculate Shellfish production, and deduct the existing stock of wild filter feeders to calculate the capacity of shellfish farming, and then tested by food restriction index method. The results of the determination are as follows: The breeding capacities of the males of Pinctada martensii in the areas of Liushawan and Yingpan pearl culture areas are relatively close. The capacity per hectare is respectively 2142.6kg (including shell weight), 10.3x104ind and 2310.0kg (including shell weight), 11.1 × 104ind. According to the results of the restrictive index analysis of the pearl culture area of Yingpan, the cultivation capacity obtained from the above two models will not cause significant pressure on the ecosystem and is suitable as a reference standard for the cultivation capacity.
