摘　　要：针对水质评价中确定指标权重时存在的问题 ,尝试用二元对比法来确定指标权重 ,在此基础上构造水质评价的多目标模糊优选模型 ;最后用一个实例证明了该模型具有简便、合理。Considering the existing water pollution problem at home and abroad and the shortcomings of some applied environment evaluation methods, this paper analyzes the main problems in current water quality assessment. After discussing the limitations of methods of calculating weight, this paper uses dualistic factor contrast to calculate weight of indexes. Then fuzzy multi-objective optimization model is developed. A case study shows how reliably, reasonably and informatively this model works.
