【摘要】 将海水水质监测值和标准值相结合,建立水质评价矩阵,通过熵权法确定各评价指标权重,应用综合指数法对泉州湾水质进行评价。结果表明,2000年之前,泉州湾水质虽有所波动,但均明显优于三类水质标准。2001年泉州湾水质出现恶化,但仍优于四类水质标准。该研究改进了传统的海水水质评价方法,计算更为简便,评价结果更合理。更多还原

【Abstract】 By means of combined monitoring date with standard values,this article has build water quality assessment matrix,used entropy method to define the scale of each index,applied composite index method for evaluating water quality of Quanzhou Bay.The results showed that water quality of Quanzhou Bay was significantly better than the Grade III despite the fluctuations before 2000.Water quality of Quanzhou Bay was deterioration in 2001,but it was still better than Grade Ⅳ.The study tried to improve traditional water quality evaluation method.The calculation is more simple,and the results is more rational.更多还原
