-
摘要: 根据主成分分析模型中的相关结构分析理论,构造了一个在水稻土肥力水平分类中对主要肥力因素指标进行筛选的数学模型,并通过实例进行了验证,取得了良好效果。Abstract: In this paper , According to the theories of correlation analysis in principal component analysis, a model on selecting main factor in grading paddy soil fertility was built . An application example was given, and the results showed that the model was in good agreement with the practice.
