| 摘要: |
| 本文采用模糊集理论以及指数法,分别对北海港湾的水质进行了综合评价,两种方法对总体水质的评价结果均为Ⅱ级,说明湾内的水体略受到轻微的污染。但就各测站而言,两种方法的评价结果是不一致的,一般相差一个级别,相对地说,模糊集理论法评价水质严于指数法。 |

| Abstract: |
| By fuzzy-set theory and exponential method respectively, this paper evaluates the water quality in Bei Haj Gulf.Evaluation results of overall water quality by two methods are both grade I. showing water of Bei Hai Gulf slightly polluted. For every observation station, the evaluation results by the two methods are not consistent, generally one-grade different. Relatively speaking, evaluation by fuzzy-set theory is stricter than that by exponential method. |
