Abstract

The trophic structure of macrobenthos in Tanggu littoral zone, Tianjin city was investigated in June 2003. The mean value of secondary production in the studied area was 42.02g/m~(2)(AFDW).The trophic structure in the investigation zone consisted of 4 trophic levels. There were fewer species of macrobenthos at some trophic levels, and the biomasses of the macrobenthos was very different. The trophic structure of this zone was not reasonable, and on this basis, some advice for bioremediation is also discussed in this paper, such as transplant and the restrainability of macrobenthos.
