Application of Multiple Indicators in Environment Evaluation of Coastal Restoration Engineering: A Case Study in Bohai Bay in China

Abstract:

Marine environment especially coastal ecosystem has unique hydrological and biological characteristics. However, increased human activities have caused intertidal area destroyed at alarming rates. Environment protection and restoration engineering have become world’s focus. The coastal ecosystems in Bohai Bay have been recognized for providing various ecological functions. The increasing stress caused by human activities induced changes in this area recently. The governors and researchers have conducted restoration engineering. To find out whether the ecosystem health status of marine environment in this area has been changed correspondingly, multiple ecological indicators of different levels including diversity, species biomass and abundance, and thermodynamic indicators were applied. The indicators include Shannon-Wiener index, Margalef index, W-statistic and exergy. The results showed that the marine environment become to moderate disturbed from severely disturbed after coastal restoration engineering according to all the indicators.
