【摘要】 对物无分析理论在水环境质量评价中的应用进行了探讨，叙述了方法的原理、模型及计算过程。运用物无分析法、多目标决策的代序法和密切值法对实例进行了评价比较．结果表明，物元分析法结构合理，计算商便适用，分辨率高，排序结果与实际环境质量状况较符合，方法是可行的。更多还原

【Abstract】 The application of matter element analysis theory to water environment quality assessment was discussed,and its principle, model and calculation procedure was introrduced. Examples assessments were compared among the matter element analysis. the priority order of multiobjec-tive decision and osculating value methods. As a result,the method is feasible, with rational structure. simple and practical calculation, higher distinguishability and se-quencing in keeping with the actual environment quality.更多还原
