摘　　要：密切值法(OsculatingMethod)作为一种多目标优选方法,在水环境质量评价中具有一定的应用。经过改进,将环境标准作为评价样本,参与到地面水环境样本的矩阵中,可以分析出各个监测断面的水质优劣排序,并使其与各级环境标准的关系一目了然。引入层次分析法,对各评价指标的贡献程度加以确定,保证了地面水环境质量评价的科学性。As a multi-objective decision optimization method, osculating method has been used in assessment on environmental quality of surface water.Modified osculating method considers environmental criteria as samples of environmental matrix.Osculating value of every sample is given to make sure the qualities of all surface water sections.Moreover,analytic hierarchy process was used to decide the contribution of each index.It makes the result of environmental quality assessment on surface water more scientific.
