Biological integrity refers to the capacity to sustain a healthy ecosystem comprising multiple biological communities within a region. Robust assessments of biological integrity thus require the sampling of multiple biological groups. We evaluated the ecological health of the Qingyi River Basin (QRB) using three indexes of biotic integrity (IBIs), including those based on the phytoplankton (P-IBI), zooplankton (Z-IBI), and benthos (B-IBI), and found that the health of the QRB system was “good” according to P-IBI (75.9 ± 17.9), Z-IBI (74.8 ± 21.8), and WQI (92.2 ± 5.3) and “moderate” according to B-IBI (43.8 ± 16.1). The assessments of the reliability of the three IBIs by exploring the relationships between biological communities and water quality environments from multiple perspectives revealed that the three IBIs were spatially positively correlated with WQI, Pearson and linear regression (P |
