Abstract
The northern East China Sea is currently subjected to anthropogenic disturbances during the past few decades. Using data collected in July 2019 and July 2020, the AZTI's Marine Biotic Index (AMBI), multivariate-AMBI (M-AMBI), Shannon–Wiener diversity index (H′), and BENTIX index were adopted to assess their applicability and evaluate the benthic ecological quality of the northern East China Sea. The results of the Pearson correlation between biotic indices and eutrophication environmental factors showed that H′ and M-AMBI were suitable biotic indices for evaluating the benthic ecological quality in the northern East China Sea rather than AMBI and BENTIX. The overall benthic ecological quality in the northern East China Sea was moderate to good during 2019–2020. Ecological quality showed a positive correlation with distance to mainland. However, a slow declining trend was detected for the benthic ecological quality of the northern East China Sea, especially the nearshore areas.
期刊介绍:
The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
