| 中文摘要 |
| 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√P×(P/R)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。 |
| 英文摘要 |
| Under the standard conditions, the oxygen production rates (P) and respiratory rates (R) of natural plankton communities were measured.Meanwhile, chemical and biological characteristics were tested in water, such as T-N, T-P, CHLa.Data sets were handled by means of variance analysis, correlation analysis, and multiple regression. The F value, SQRT (P×(P/R)), was determined as the suit metabolic rate index in evaluating eutrophication. Having based on probability, the opening classification with F and a judgement model which could partition nutrient type were set up quickly and accurately. |
