To study the relationships between in-stream total nitrogen (TN) and phosphorus (TP) loads and responses of epilithic algal metrics, nonparametric change-point analysis (nCPA) and thresholds indicator taxa analysis (TITAN) were used to detect possible TN and TP thresholds for algal chlorophyll a, diatom richness, Shannon diversity index, and diatom community composition for tributary rivers of the Three Gorges Reservoir (TGR). We found that nCPA simulated similar TP thresholds for all the four algal metrics (-0.03 mg·L为全面了解河流附石硅藻群落对水体氮、磷变化的响应规律,并找出氮、磷指示物种,本研究采用非参数突变点分析法(nCPA)及临界指示物种分析法(TITAN)探讨了三峡水库入库支流附石藻类叶绿素a、硅藻物种丰富度、Shannon多样性指数以及硅藻群落组成的总氮(TN)、总磷(TP)阈值.结果表明: 据nCPA得到的所有藻类参数的TP阈值均接近0.03 mg·L |
