摘要
选取浮游植物初级产量、浮游植物现存量、有机物耗氧量、总氮、无机氮、总磷、活性磷等七项指标,由德尔菲法确定各指标的类别界限值和权重,用灰色系统理论的定权灰色聚类方法,借用计算机对23个湖泊和水库营养类型主要参数作灰色聚类分析,以建立一种划分我国湖泊和水库营养类型的有效方法,作为渔业生产的依据。
A trophic classification of Lakes and Reserviors based on 7 main index is studied by Gray Cluster Analysis in this paper. The result here corresponds with real situations and can serve the fishery production as an effective method.
