主成份分析在土壤分类研究中的应用,已初步显示出它的成效.然而,就主成份分析应用于土壤分类的作者数量而言,国内又尚不多.这可能是由于它的常规解算法较繁,而用大型电子计算机又受条件限制之故.因此,必须寻找一种解算简便、易于掌握而精度可靠的主成份分析法.近来,在研究土壤遥感信息分类技术中,摸索出一种主成份分析简便解算法(下称简便解算法).这种简便解算法,只要具备高中数学基础就可掌握.现就其解算原理、程序、精度及其应用问题作一介绍.
The application of principal component analysis in the study of soil classification has initially shown its effectiveness.However, the number of authors applying to soil classification by principal component analysis is still low, which may be due to its conventional solution method Therefore, it is necessary to find a principal component analysis method that is simple, easy to grasp and reliable. Recently, in the research of soil remote sensing information classification technology, we have found a The principal component analysis of the simple solution algorithm (hereinafter referred to as the simple solution algorithm), this simple solution algorithm, as long as the high school mathematics can grasp the master. Now its solver principle, procedures, accuracy and its application issues are introduced.
