摘要

关联性的存在是多指标综合评价中一个不可避免的问题。在国内外研究基础上提出定量分析和定性分析两种关联性判别方法,分析各自的适用范围。以健康长江评价指标为例进行关联性分析,认为健康长江评价的一级指标基本是相互独立的,但二级指标之间、某些二级指标和其他一级指标之间关联性比较强。分析结果表明评价指标体系的建立要注重关联性的分析及其影响的消除。

Abstract

Correlation among indexes is an ineluctable problem in comprehensive evaluation. On the basis of the research at home and abroad, two methods of correlation analysis, i.e. quantitative analysis and qualitative analysis were proposed to analyse their scopes of application. As an example, the correlation analysis was applied to the analysis of indexes of healthy Yangtze River assessment. The result shows that indexes of the first class are generally independent, but indexes among the second class and some of them with first class indexes are correlative strongly. It is demonstrated that the correlation analysis and elimination on indexes must be emphasized in the establishment of indexes system.
