摘要
选取9项主要河流健康系统评价指标,建立了河流健康等级综合评价的熵投影寻踪模型。利用该模型对沂河进行了健康等级综合评价。评价结果表明:沂河的河流健康隶属度计算值为0.551,健康水平处于亚健康状态,这与基于专家咨询的层次分析法的评价结果相一致。由此可见,该模型是有效的和通用的,可以广泛应用于各种环境质量综合评价中。
Comprehensive grade evaluation by nine evaluation indexes of river health based on projection pursuit of entropy is proposed as a new evaluation approach in this paper. The results of this model applied to evaluate Yihe river show that the calculated membership degree value of river health fuzzy set is 0. 551,so Yihe River belongs to the grade of interior health,which is coincide with the results of AHP. The results show the model is effective and general and can be widely applied to various comprehensive evaluation of environmental quality.
