摘要
本文提出一种新的权重分配方法,建立了线性插值隶属函数,应用模糊数学中的综合评价法对某海域的水质按站点、断面和海域三个层次进行了综合评价,评价结果与实际状况吻合很好,为海域总体水质的横向、纵向比较提供了一种方法。
A new method is put forward to assign weight for each factor and a membership function is established in the paper. Comprehensive evaluation of fuzzy mathematics is applied to assess the seawater quality. The assess is divided into 3 levels, the first level for individual point, the second level for a cross section and the third level is for the investigation sea area. The assessment result is perfectly in accord with the fact. So a new way to compare seawater quality in deferent area and deferent time is provided.
