摘    要:应用灰色关联度分析法对顺德高产池塘的多品种混养鱼类关系进行分析,各种不同鱼类的放养对产量的关系为:鲮放养量对镛的净产量影响最大(G34=0.7921),其次为草鱼放养对鲮的净产量影响(G13=0.7415),最小为鲢的放养对草鱼的净产量关系(0.5932)。鲮的放养为优势母因子,鳙的收获为优势子因子。应用灰色动态模型GM(1,2)建模法建立了高产池塘主体鱼的产投关系模型,在该模型的基础上建立了系统

关 键 词:高产池塘  混养鱼类关系  投入产出模型

Abstract:The gray correlativity analysis was applied to study on the relationships among fishes in high yield poly culture pond. The results are as follows: the relation between the input of mud carp fingerlings and output of big head carps is the biggest( R =0.7921), and the relation between the input of grass carp fingerlings and output of mud carp is the second ( R =0.7415).The input mud carp fingerlings becomes superiority maternal factor, the output of big head carps becomes superiority junior factor. The gray dynamics model is applied to analyse the input output. and a dynamic equation is developed. The results indicate that the system can develop steadily only if a 30% of net yield value is remained for next year's carp fingering.
Keywords:high  yield  pond  relationship of ploy  culture fishes  input  output model  gray system theory
