摘    要：通过理论阐述及实例分析,对指数法、模糊综合评判法、灰色聚类法和物元分析法等四种常用的水环境质量评价方法进行比较分析,并对各种评价方法的优点和不足做出总结。结果表明,物元分析法的评价结果更趋合理。

Abstract: Through theoretical explanation and case analysis,the common methods of water environment quality assessment,such as exponent evaluation,fuzzy synthetic evaluation method,grey clustering method and matter element analysis method,are compared and analyzed,and their advantages and disadvantages are described.The results show that the matter element analysis method could get better agreement with practical water environmental quality than that the other methods.
