Abstract

Abstract

The meiofauna was investigated in mangrove of Dongzhai Bay, Hainan in February 2012. The results showed the main meiofauna group were Nematoda, Copepoda, Turbellaria, Polychaeta, Oligocheata, Halacaroidea and a few unidentified meiofauna in the investigated area. Free living nematode was the most dominant group, and accounted for 95.30%,97.02%,96.45%,90.53% of the meiofauna abundance in each stations. The meiofauna abundance in mangrove of Dongzhai Bay was (1 082.23±563.76)ind/(10 cm²), and the biomass was (764.06±511.63)μg/(10 cm²).The Shannon-wiener diversity index(H')was 0.26, 0.17, 0.20, 0.45, and Pielous species uniform(J)was 0.13, 0.09, 0.10, 0.23, respectively. Least significant range method (LSR) for multiple comparisons analysis showed that meiofauna in each stations was significant difference. Mangrove of Dongzhai Bay could be polluted by organic matter according to ratio value of Nematoda and Copepoda.
