摘　　要：以厦门同安湾为例,利用1995～2005年的监测数据,分别采取污染物浓度超标加权法、主成分分析法和对比排序法三种权重识别方法对近岸海域水质时间序列上的演变规律进行模糊评价的比较。结果表明,三种权重识别方法的评价结果一致,均可作为同安湾水质模糊评价的权重确定方法;同时,还分析了三种权重确定方法在应用过程中的优缺点,并进行了比较,为海湾水质模糊评价中的权重确定提供参考。The three recognition methods of weight coefficient including exceeding pollutant＇s concentration stan- dard, main contents analysis and comparison sequence were used in fuzzy evaluation of chronical water quality in Tong＇an Bay of Xiamen. It was found that these three methods were equally effective for water quality evaluation because of the little difference between them. In addition, the advantages and disadvantages of different methods to provide scientific reference for determining the weight in fuzzy evaluation of water quality were discussed.
