回归分析在研究家畜数量分布与生态因子关系中的应用

Application of the Regression Analysis on the Relationship Between the Domestic Animal Amount and Ecology Factors

采用线性化变换方法,建立正规方程组,获得了川西北高原地区牦牛、绵羊及山羊数量多个生态因子间的多项式回归方程。同时对具有显著性的方程式进行单因子边际分析,结合实际观测样本获得了家畜生长的最适宜生态环境条件。

We adopted the linearization mutation means to establish the normal equation series, and obtained the polynomial regression equation of the ecology factors such as amount of yak?sheep and goat in the northwest highland area of Sichuan province. Meanwhile, carrying on single factor bound analysis to the equation which had significance, combining practice, observing the most suitable ecology conditions which the domestic animal growing in.
