Statistical analysis on temporal pattern of the FFG of macroinvertebrate
communities revealed that the macroinvertebrates increase significantly
in the Shannon-Wiener index and Pielou’s evenness in normal season, and
decrease in dry season. The Margalef’s richness index increased
gradually and exhibited a significant interaction in different seasons.
