Effects of Reclamation Projects on Marine Ecological Environment in Tianjin Harbor Industrial Zone

The living environment of marine plankton and benthos has been affected by reclamation projects. The investigation of living environment of marine plankton and benthos in Tianjin Harbor Industrial Zone was carried out three times from 2006 to 2008. The results showed that the Shannon-Weaver diversity index of phytoplankton and zooplankton decreased from 3.01 to 1.71 and 1.7 to 0.58, respectively. In addition, the diversity index of Shannon-Weaver of benthos decreased to zero from 1.28. The results showed that reclamation projects would change the living environment of marine organism, decrease the diversity of biology and change the structure of community.
