三峡库区支流底栖硅藻功能群特征及其驱动因子分析——以汝溪河为例
Functional group characteristics of benthic diatoms and its driving factors in the branch of Three Gorges Reservoir: A case study of Ruxi River
摘要
Abstract
The seasonal succession of function groups in benthic diatom and its relationship with environmental factors were investigated in Ruxi River,an important branch of Three Gorges Reservoir.Results showed that 168 species of benthic diatoms belonging to 27 genus,8 families were found in this river,and these species were categorized to 8 functional groups including B,C,D,Lo,MP,P,X3 and TB during three different water periods for low,level and high water period,and MP was absolutely dominant.Redundancy analysis suggested that seasonal succession of functional groups in the benthic diatom was mainly determined by nitrite,conductivity,phosphate,permanganate index and water temperature.关键词
