摘要
就物元分析法和模糊综合评判法在河流水质评价中的应用,从适用范围,数学模型的建立、权重的确定方式,以及评价结果的可信度等几方面进行分析与对比.结果表明,物元分析法在解决水质评价中的不相容问题,以及刻画水质动态转化趋势方面均优于模糊综合评价法.对模糊综合评价法在应用中存在的问题,文中提出改进措施.
The different usages of matter element and fuzzy comprehensive evaluation methods in river water quality assessment, are analyzed and compared with each other in the following aspectsz their applicable scopes, mathematic models, weighted indexes, reliability. Incompatible problem and dynamic trend in water quality assessment can be solved by the matter element analysis method, which is better than fuzzy comprehensive evaluation method. The improvement of fuzzy comprehensive evaluation method is put forward to solve the practical problems.
