Marine Coastal Ecosystem Health Assessment: A Case Study in Jiaozhou Bay, China
In this paper, a marine coastal ecosystem health assessment indicators system is established, and it covers hydrographic, geographical, physical, chemical, biological, system-level and ecosystem-severe-functional aspects of coastal ecosystem health. The indicators system was used in a case study in Jiaozhou Bay. The assessment results showed that Jiaozhou bay was healthy in the time series from 1980s to 2000s, but the health evaluation index showed a decline trend. The main influencing factors of Jiaozhou Bays health are macrobenthic community, phytoplankton community, coastal land indicators, water quality, and main human activities that have threatened the bays health are land reclamation and sewage discharge.
