河流健康系统是由众多不确定性和复杂性因素组成的,五元联系数是集对分析中同异反联系数的推广,它可更深入地分析系统中的各种不确定性.用层次分析法确定指标权重,从主客观两方面定量计算河流健康程度,将五元联系数应用于黄河健康系统的评价,用联系度可描述评价对象与评价标准之间的关系,其结果简便直观,能清晰地反映评价对象和评价标准间的联系.得到河流健康评价等级为"亚健康",其结果与有序度熵的河流健康评价方法所得结果一致.

River health assessment system consists lots of uncertainty and complexity. Five-element connection number is the improvement of the identical,discrepancy and contrary connection number in set pair analysis theory,which can be more thoroughly used for system uncertainty analysis. Analytic Hierarchy Process (AHP) is applied to determine the weights so that the health degree of river can be calculated from the objective and subjective evaluations. In this paper,the health condition of Yellow River is assessed using the five-element connection number,which can clearly describe the relationship between evaluated object and evaluation criterion. The results showed that the health degree of this river was Sub-health and consistent with the other methods such as system order degree entropy.
