摘　　要：将模糊数学的基本原理引入到湿地水质评价中,对天鹅洲、黑瓦屋长江故道湿地水质状况进行综合评价研究。根据监测断面水质污染特点,确定7个指标作为评价因子,建立评价因素矩阵,计算出影响因子的权重。在此基础上构建了湿地水质模糊综合评价模型,计算出天鹅洲、黑瓦屋长江故道各监测断面的水质级别,证明两故道湿地的污染物主要是氨氮、总磷和有机物。Based on fuzzy mathematics, a mathematical model was developed for water quality evaluation, the water quantity in Tian＇ e-zhou and Hei-wa-wu Oxbows of the Yangtze River was evaluated in this paper. According to pollution feature of water, 7 indicators were determined as the evaluation factors. On the basis of this, a fuzzy synthetic evaluation model was developed for the wetland water quality evaluation and the fuzzy synthetic evaluation levels of the section were obtained in Tian＇ e-zhou and Hei-wa-wu Oxbows of the Yangtze. The results showed that nitrogen, total phosphorus and organism were the main pollutants.
