摘要
最近邻法是一种传统的基于实例的分类方法,将最近邻法应用到水质综合评价中,建立了最近邻模型,利用三峡库区城市江段13个监测断面的检测数据进行评价,评价结果表明,水体尚清洁,综合污染程度不严重.为验证最近邻法评价结果的有效性,对模糊综合评价法和最近邻法的评价结果进行比较,得到了较好的效果,具有推广价值.
Nearest Neighbor algorithm is a traditional case-based classification method. This paper used the Nearest Neighbor algorithm in comprehensive evaluation of water and established the Nearest Neighbor model. Aiming at the water quality assessment of the Three Gorges reservoir area, the model was used and the results showed that the water quality is good. The degree of integrated pollution is not serious. In addition, we compared with fuzzy comprehensive evaluation method and got good effects. It is worth promoting.
