Abstract:

Benthic macrofauna were classified into 5 functional groups, i.e. planktophagous (Pl), phytophagous (Ph), carnivorous (C), omnivorous (O) and detritivorous (D). The biotope difference, seasonal and annual variations of functional group of benthic macrofauna in the intertidal zone of the 14th Yong of Nansha, Guangzhou were analyzed in this study according to the four seasonal data of benthic macrofauna collected in two biotopes (Cyperus malaccensis and Sonneratia caseolaris) in 2007-2008 and 2013-2014. A total of 26 species were recorded in 2007-2008, which was lower than 36 species in 2013-2014. Both in 2007-2008 and 2013-2014, phytophagous group showed the highest value while detritivorous group shared the lowest one in density and biomass. Habitat comparison showed that the abundance index (d), evenness index (J) and diversity index (H') of planktophagous group in Cyperus malaccensis habitat were all higher than those in Sonneratia caseolaris habitat. Annual comparison showed that the abundance index, evenness index and diversity index of planktophagous group in 2013-2014 were all higher than those in 2007 -2008 both in Cyperus malaccensis and Sonneratia caseolaris habitats because the planktophagous such as Gelonia coaxans and Morerlla iridescens and so on were collected in 2013-2014 but they were not found in 2007-2008.
