摘　　要：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 theory of nutrition dynamics in marine ecological system,the investigation and research were carried out on primary production,the existence biomass of wild filtering animals,organic carbon content in Pinctada martensii,the filtering ratio of the shellfish and etc.,in Liusha Bay and Yingpan pearl-cultured zones.Nutrition motive model and coast energy flowing model were used to estimate shellfish maximum production.The carrying capacity of shellfish was estimated by excluding the existence biomass of wild filtering animals,and inspected by the methods of food limited indexes.Results are as follows that the above-mentioned two areas have approximate capacity,the capacities were 2142.6kg（with shell weight） per hectare,10.3 104ind and 2310.0kg（with shell weight） per hectare,11.1 104ind.Analyzed by the methods of food limited indexes to Yingpan pearl-cultured area,the number of breeding under carrying capacity wouldn＇t constitute a significant pressure onto ecosystem,and that is suitable to do as a reference of carrying capacity.
