摘　　要：Meiofauna are fundamental components in mangrove ecosystem which play important roles in the energy flow and mat-ter cycling.In order to reveal the spatio-temporal distribution of meiofaunal assemblages in mangrove habitats,sediment samples were collected in July(summer)and October(autumn)of 2013,January(winter)and April(spring)of 2014 in the mangrove tidal flat of Futian,Shenzhen,China.A total of 14 meiofaunal taxa were identified,including free-living marine nematodes,benthic copepods,polychaetes,oligochaetes,ostracods,isopods,etc.Additionally,there were also undetermined taxa.Results showed that the abun-dance range of meiofauna was(488.35±71.29)-(5136.36±623.38)ind(10 cm)−2.Marine nematodes were the most dominant group,with an average abundance of(1869.56±227.92)ind(10 cm)−2,accounting for 98.35%of the total abundance of meiofauna.The sea-sonal distribution of meiofauna showed that the abundance was the highest in summer,followed by those in spring,winter,and au-tumn.Vertical distribution showed that meiofauna were mainly distributed in the upper sediment layer(0-5 cm),with a proportion of 89.56%.Correlation analysis between meiofauna and environmental factors showed that meiofaunal abundance and biomass had significantly negative correlation with salinity.BIOENV analysis between meiofaunal assemblages and environmental factors show-ed that meiofaunal assemblages were affected by the combined effects of temperature,salinity,sediment median grain size,water content,and chlorophyll a content.
