摘要
针对环境质量中综合评价工作中常用的主成分分析方法进行了研究 ,探讨了特征向量的方向对用主成分分析方法做综合评价的影响 ,与其他情况下的作用进行了比较 。
In connection with environment quality synthesis evaluation the main composition analysis method in common use was researched in this paper. It also discussed the influence of characteristic vector direction on synthesis evaluation when the analysis method of main composition was used. By comparing with other methods, the correcting opinions for environment quality synthesis evaluation were given out.
