摘要
应用灰色关联分析法，分析了影响珠江三角洲与长江三角洲池塘净产量及净产值的主因子，影响珠江三角洲池塘鱼净产量的主因子为：草料投喂量、鱼种放养量，影响净产值的主因子为草料投喂量；影响长江三角洲池塘鱼净产量的主因子为：贝类投喂量、鱼种放养量，影响净产值的主因子为：鱼种放养量、贝类投喂量。并根据主因子建立了两地的净产量的灰色动态GM（1，2）模型。
The gray correlativity analysis was applied to study the effect of dominantfactors on net-production-cost in high-yield-fish-pond for the Pearl River Delta and YangtzeDelta. The dominant factors effected on net-yield were input of grasses, input of figerings,and the dominant factor effected on net-production-cost was input of grasses in Pearl RiverDelta. As for the Yangtze Delta, the dominant factors effect on net-yield were input of spiralshell, input of fingerings, and the dominant factors effected on net-production-cost wereinput of fingerings and input of spiral shell. The gray dynamics models GM(1, 2) of net-yieldfor these areas were built by using dominant factors.
