摘要
应用灰色聚类法对海水水质进行评价,参照GB3097-1997海水水质标准,通过灰类白化权函数描述海水水质分级界限,确定了各参评指标对不同等级的聚类权。在此基础上构建了海水水质灰色聚类法综合评价模型,以此对2004年长江口及邻近水域渔业环境水质状况进行评价。与综合指数法相比,灰色聚类法保证了评价结果的客观性和准确性。
Grey clustering method is applied to evaluate seawater quality. With the reference of GB3097 - 1997 seawater quality standard, grey whitenization weight function is used to describe the limit of seawater quality classification, and clustering weight is selected correctly. Based on grey theory, a mathematical model for evaluating seawater quality of wetland is establ ished, which can evaluate the seawater quality in the Changjiang River estuary and fishery waters nearby. Compared to the assessment result of comprehensive index, grey clustering method proves to be objective and exact.
