摘　　要：随着水生态系统水体污染和富营养化程度的加剧,很容易诱发大面积水华.水华造成严重的环境污染及水体污染,对水产淡水养殖业是一个严重的打击.因此研究淡水养殖池塘水华发生及池水净化处理具有重要意义.首先在SPSS中利用Pearson相关系数法选取主要的理化因子,然后建立多元线性回归模型研究各理化因子与浮游生物致害密度之间的关系,并预测在水华发生时各个理化因子的范围.鲢鱼和鳙鱼对水体具有净化作用,在MATLAB中拟合鲢鱼鳙鱼生长模型,并在LINGO中建立线性规划模型确定能够使水池净化鲢鱼鳙鱼最优的放养量.并根据研究的结果构建绿色节约的生态养殖模式.With the aggravation of water pollution and eutrophication in water ecosystem,it is easy to induce large area Algal Blooms. Algal Blooms cause serious environmental pollution and water pollution,which is a serious blow to aquaculture. Therefore,research on occurrence of Algal Blooms and purification and treatment of water in the freshwater aquaculture ponds has important significance. In this paper,firstly,the main physical and chemical factors were selected in SPSS by the Pearson correlation coefficient method. Then,a multiple linear regression model was established to study the relationship between each physical and chemical factors and the density of plankton,and to predict the range of each physical and chemical factors when Algal Blooms are occurring. Silver carp and bighead have good effect on water purification,the growth model of silver carp and bighead is fitted in MATLAB and the linear programming is es-tablished in LINGO,so as to determine the optimal stocking quantities of silver carp and bighead that can make the pool cleaning. Next,the green ecological conservation mode is constructed according to the research results,and the last part is the conclusion of the article.
