- Abstract
In order to understand the secondary productivity of macrobenthos in different botanic habitats in intertidal zone in Gaoqiao of Zhanjiang, the Brey's empirical formula was applied to calculate the secondary productivity based on the investigations in the habitats of Sonneratia apetala, Aegiceras corniculatum, Sporobolus virginicus, and Bruguiera conjugate in four seasons. 2010. The secondary productivity of the macrobenthos in the habitats in four seasons was averagely 11.77 g AFDM · m-2 · a-1, being the highest in S. apetala habitat (18.16 g AFDM · m-2 · a-1), followed by in A. corniculatum habitat (17.67 g AFDM · m-2 · a-1), S. virginicus habitat (8.34 g AFDM · m-2 · a-1), and B. conjugate habitat (2.92 g AFDM · m-2 · a-1). The P/B ratio of the marcobenthos was the highest in B. conjugate habitat (2.38), followed by in S. virginicus, S. virginicus, and A. corniculatum habitats, with the values of 1.23, 0.99, and 0.48, respectively. The differences in the secondary productivity and P/B ration of the macrobenthos among the four botanic habitats were mainly related to the sediment total organic carbon, food type, and macrobenthos individual size.
