摘要
磷是湖泊富营养化的主要限制因子。应用多元线性回归模型对乌梁素海湖泊实测水质数据进行统计回归分析,并对回归方程进行检验。经检验,统计量FP=6442.87,多元线性回归模型通过F检验,认为回归方程的效果比较显著,效果良好。结果表明:多元线性回归模型可以用在富营养化水体主控因子总磷的研究中,并进行分析、模拟预测。
Phosphorus is the main limiting factor in lake eutrophication. By using multiple linearity regression model,we analyzed the measured data of the water quality for the lake,and derived regression equation. Regression equation was passed F test,statistics FP=6442.87. Multivariate linearity regression equation was passed F test and the effect was more significant. The results showed that the multiple linearity regression model can be used in the main limiting factor in lake eutrophication-Phosphorus.
