Fig. 2. Seasonable distribution of abundance and biomass of FFGs in the Jingui River
The Pearson correlation analysis revealed that the abundance of macroinvertebrates was positively correlated with CODMnin normal season and with TN in dry season. In contrast, biomass exhibited negative correlations with WT, Cond, and NO3--N in wet season, complete relationships with WT, Cond, and NO3--N in normal season, and positive an association with TN in dry season (Table 4).
