珠江三角洲与长江三角洲高产池塘因素分析及产量模型的比较研究

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，影响净产值的主因素为草料投喂量；影响工江三角洲池塘净产量的主因子为：贝类投喂量、鱼种放养量，影响净产值的主因子为：鱼种放一、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 COMPARATIVE STUDY ON FACTORS ANALYSIS AND YIELD MODEL OF HIGH-YIELD FISH-POND FOR THE PEARL RIVER DELTA AND YANGTZE DELTA

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.
