图8. 基于冗余分析方法的拉萨河中下游纲级水平上各纤毛虫类群与环境因子之间的关系。WT: 水温; EC: 电导率; TDS: 总溶解盐; Salt: 盐度; DO: 溶解氧; COD: 化学需氧量; TN: 总氮; TP: 总磷; NH₄⁺-N: 氨氮; NO₃^--N: 硝态氮; TUR: 浊度; WS: 水流速度。Oligohymenophorea: 寡膜纲; Spirotrichea: 旋毛纲; Colpodea: 肾形纲; Heterotrichea: 异毛纲; Phyllopharyngea: 叶咽纲; Nassophorea: 篮口纲; Prostomatea: 前口纲; Litostomatea: 叶口纲; Karyorelictea: 核残迹纲。

Fig. 8. RDA method was used to analyze the relationship between ciliate groups and environmental factors at class level in the midstream and downstream of Lhasa River. WT, Water temperature; EC, Electrical conductivity; TDS, Total dissolved salt; Salt, Salinity; DO, Dissolved oxygen; COD, Chemical oxygen demand; TN, Total nitrogen; TP, Total phosphorus; NH₄⁺-N, Ammonia nitrogen; NO₃^--N, Nitrate nitrogen; TUR, Turbidity; WS, Water flow speed.
