上海水体营养分级的群落代谢率模型

Metabolic Model of Plankton Communities in Eutrophication Classification in The Waters of Shanghai

在标准实验条件下测定天然浮游生物群落的产氧率（Ｐ）和呼吸率（Ｒ）。同时结合总氮、总磷、叶绿素ａ等水质化学、生物学指标，运用方差分析、多元逐步回归分析等定量研究手段，确定Ｆ值即为代谢率的合适指标评价富营养化。在概率基础上确定Ｆ值的开放型分类，并建立了能快速、准确判别营养污染程度的判别模型。

Under the standard conditions, the oxygenproduction rates (P) and respiratory rates (R) ofnatural plankton communities were measured.Meanwhile, chemical and biological characteristicswere tested in water, such as T- N, T- P, CHLa.Data sets were handled by means of varianceanalysis, correlation analysis, and multipleregression. The F value, SQRT (P × (P/R ) ), wasdetermined as the suit metabolic rate index inevaluating eutrophication. Having based onprobability, the opening classification with F and ajudgement model which could partition nutrient typewere set up quickly and accurately.
