结果表明：劳均产值、单位耕地产值、人均产值是决定第一主成分的主要指标；氮平衡指数、劳均产值、单位耕地施用农药量是决定第二主成分的主要指标；磷平衡指数、钾平衡指数、人均产值是决定第三主成分的主要指标。 | | 3. | Therefore , spca gotten via selecting polynomial kernel functions is more accurate than pca in multi - index evaluation system , and has fewer dimensions . comparatively , for spca using gauss kernel function and laplace kernel function , it is required to normalize original data according to the category , and the constructed evaluation functions are better than the ones constructed via using pca . however , if variance contribution of first principal component of pca is more than 85 % , evaluation function curves of spca and pca are similar
在作多指标评价中，选用多项式核函数而得到的谱主成分分析，比主成分分析得到的主成分具有维数低且精度高的优点；而用gauss核函数和laplace核函数的谱主成分分析，需对原数据作同类别数据间的规范化，其构造的评价函数也优于用主成分方法构造的评价函数。 |
