摘  要:
[目的]采用模糊物元模型评价河流健康状况。[方法]基于模糊物元分析原理,建立河流健康评价模型,并根据海明距离提出改进的从优隶属度计算方法;从水文特征、生态特征、环境特征和服务功能4个方面构建河流健康评价指标体系,并将其用于秦淮河健康评价实例中。[结果]秦淮河健康水平为"中"级别;该评价结果与综合指数法得出的评价结果基本一致,证明了多级别模糊物元分析模型的有效性。[结论]该研究为河流健康评价提供了一种有效的方法。

摘  要:
[Objective] The study aimed at assessing the state of river health by using fuzzy matter-element model.[Method] Based on fuzzy matter-element analysis theory,the assessment model of river health was established,then a modified method to calculate the prior subordinate degree was put forward according to Hamming distance.Afterwards,a multi-level evaluation model,which contained the assessment indexes about hydrological features,ecological characteristics,environmental traits and service founction,was set up based on the method above.Finally,the model was applied in the health assessment of Qinhuai River.[Result] The health level of Qinhuai River was medium.The assessment result was consistant with that of comprehensive index method,and it showed that the multi-level fuzzy matter-element model was effective in the assessment of river health.[Conclusion] The research provided an effective method to evaluate the state of river health.
