在对水环境质量综合评价中,多目标决策-理想区间法解决了水环境质量评价标准是区间而非点的缺陷.但是在计算监测点到各理想区间向量的距离时,各水环境质量指标权重直接影响综合评价的结果,通常的确定方法是简单的假设各水环境质量指标的权重相等,这与实际情况相悖.为了解决这一问题,提出了将超标法用于多目标决策法中,利用超标法确定各水环境质量指标的权重,然后将其应用于多目标决策-理想区间法来分析水环境质量等级.并将改进后的多目标决策-理想区间法应用于珠江口及邻近海域的水环境中.基于超标法确定权重的多目标决策-理想区间法与聚类分析相比更有效,与等权重的多目标决策-理想区间法相比,更能体现水环境的污染状况,可应用于各种环境因子的综合评价中.

The multiple objective decision making-ideal interval method deals with the assessment standard by using ideal interval for assessing the water quality. But when the method is applied, water quality index weight affects water quality evaluation result. Normally, it is proposed that the water quality index weights are equal, which dose not accord with actual conditions. In order to overcome the defect, super-standard method is suggested and calculated the weighted value of each water quality index, and is integrated with the multiple objective decision method for assessing the water quality. The blend of super-standard method and multiple objective decision method is applied to evaluate water environment in Pearl River estuary. The result shows that the improved multiple objective decision method is more rational than equal weighted multiple objective decision method and cluster analysis method. It is a better assessment method for comprehensive assessment of water environmental quality.
