基于AMBI和M-AMBI法的桑沟湾底栖生态环境质量评价
Assessment of Benthic Ecological Quality of Sanggou Bay Thorugh AMBI and M-AMBI Approaches
摘要
Abstract
Environment assessment is an important step of evaluating maricultural healthy and sustainability.To monitor the ecological status of Sanggou Bay,macroinvertebrate samples were collected in April and July,2017.Species composition,biomass,density and community structure of macrobenthos were analyzed.The degree of disturbance of large benthic communities and the quality of sedimentary environment were evaluated though AMBI and M-AMBI approaches.Both surveys showed that polychaetes are the dominant species.In total,36 and 32 species were polychaetes found in April and July,accounting for 63.16%and 60.38%of the total,respectively.The results of AMBI and M-AMBI showed that most of the stations in the surveyed sea areas are subject to mild disturbances and several stations are moderately disturbed or undisturbed.The quality of the ecological environment was mostly good.Integrated multi-trophic aquaculture(IMTA)alleviated the pressure of Sanggou Bay coastal ocean ecosystem,and accordingly Sanggou Bay was less affected by human disturbance.The environmental quality of Seagrass area was high and that of bivalves,mixed culture and kelp areas varied between good and moderate.关键词
