Abstract:

Land reclamation is an important way to use the ocean. But frequent human activities have a far-reaching influence on local marine ecosystem. Using the Qi’ao Island sea area as the study area, we surveyed the environmental factors and the changes of the biological community before and after reclamation. From the trend of the changes in the environment and the changes of phytoplankton, zooplankton, and the diversity and species of fish before and after reclamation, we investigated the influence on local marine ecosystems caused by the reclamation projects around the southern Qi’ao Island from 2010 to 2014. The results showed that the reclamation has had different degree of negative impact in terms of heavy metal pollution and eutrophication, and reduced the stability of local biological community. The community species has also decreased after the reclamation.

Key words: reclamation, Qi’ao Island, environmental factor, biological community
