The Sonneratia apetala artificial mangroves in the intertidal zone of Da Wei Bay at Qi’ao Island of Zhuhai,
South China were chosen as the macrofauna succession plots while bare tidal flats of the same size
were established as control plots in surrounding interference-free areas. Conventional change indicators of
community structure, such as biomass and biodiversity, and indicators, such as exergy and specific exergy,
which reflect the information change of overall communities, were used to analyze the succession of macrofauna
communities in S. apetala artificial mangroves.
