环境质量评价中的主成分分析与全局主成分分析方法

The Principal Components Analysis and the Global Principal Components Analysis in the Environmental Quality Evaluation

给出在环境质量评价中对即时性平面数据的主成分分析方法与对多维动态数据系统的全局主成分分析方法,着重介绍了对时序立体数据表进行立体式的综合与简化,并应用于具体的实例,得到很好的结果.这两种方法对环境质量的评价和治理工作都有积极的指导作用与重要的应用价值.

This paper intends to give the methods of principal components analysis for the instant planar data and global principal components analysis for the multidimensional dynamic data system in the environmental evaluation, especially focuses on the synthesis and simplification of the sequential solid datasheet, then gets the satisfied result in the examination. This two kinds of methods are important and valuable in the evaluation and treatment of the environment.
