摘要
2016年3月和11月对宁德东部海域30个站位进行大型底栖动物调查,本次调查共采集大型底栖动物99种(春季75种,秋季51种),其中多毛类44种,甲壳动物22种,软体动物16种,其他类群17种。本文首次将AMBI和M-AMBI法引入宁德东部海域进行底栖生境质量评价,并将评价结果与Shannon-Weaver多样性指数(H')的评价结果相互比较,讨论其在宁德东部海域生境质量评价中的适用性。结果表明宁德东部海域大部分区域受轻度干扰,且春季底栖生态环境质量优于秋季。与H'的评价结果相比,AM-BI的评价结果等级较高; M-AMBI的评价结果等级梯度更明显且与H'更一致。因此,在底栖生物以敏感种为主的宁德东部海域,用M-AMBI和H'来评价其生态环境质量状况更为合理。
Macrobenthos was investigated at 30 stations in the east Ningde sea waters in both March and November,2016.A total of 99 species(75 species in March;51 species in November)were found,including 44 species of Polychaetes,22 species of Crustacea,16 species of Mollusca,and 17species of other taxa.In this paper,the AZTI marine biotic index(AMBI)and the multivariate-AMBI(M-AMBI),were first applied to assess the eco-environmental quality of the east Ningde sea waters,and the assessment results were compared with those by the Shannon-Weaver Indexes(H'),aimed to test the applicability of these indices to the east Ningde sea waters.The result showed that most stations were slightly disturbed,especially in autumn.Compared with the results from AMBI,M-AMBI and H',the environment pollution degrees derived from AMBI was slightly lower than those derived from M-AMBI and H'.The assessment results based on M-AMBI could be more reasonable and coincident with H'.Thus it was suggested that for the east Ningde sea waters which is dominated by sensitive benthos species,M-AMBI and H'could be more applicative and objective than AMBI in assessing its eco-environmental quality.
