通过2012年4个季度现场对如东滩涂文蛤(Meretrix meretrix)养殖区叶绿素a含量、初级生产力、文蛤有机碳含量及其带壳重与鲜组织重比值等的调查检测,获得模型参数,应用营养动态模型、沿岸能流模型、方建光模型3种估算模型估算文蛤养殖容量并对相关模型的适用性进行分析探讨。3种模式估算的贝类养殖容量分别为15 528.45 kg/hm2、25 949.10 kg/hm2、34 623.90 kg/hm2,平均为25 367.10 kg/hm2。模型估算结果表明,不仅需要应用不同的养殖容量模型同时进行对比验证,贝类自身生长变化对模型应用产生影响需要特别考虑。
Based on the field investigation of chlorophyll a content, primary productivity, organic carbon content of shellfish and its ratio of shell weight and fresh tissue weight in the quarters of 2012 in Meretrix meretrix, the model parameters were obtained and applied nutrition Dynamic model, coastal flow model, Fang Jianguang model three kinds of estimation model to estimate the capacity of clam culture and analysis of the applicability of the model. The estimated shellfish production capacities of the three models were 15 528.45 kg / hm2, 25 949.10 kg / hm2 and 34 623.90 kg / hm2, respectively, with an average of 25 367.10 kg / hm2. The results of model estimation show that not only the different models of aquaculture capacity need to be verified simultaneously, but the changes of shellfish ’s own growth need special consideration.
