摘　　要：底栖生物因其生活方式以及对环境变化的应激能力,被广泛应用于海洋生态状况的评估。目前已构建了多个底栖生物指数用于评价底栖生态状况,但因单一指数具有片面性和不稳定性,对同一区域的评价结果并不一致。为准确评价胶州湾海域的底栖生态状况,本文根据胶州湾地区底栖生物群落近七年的变化情况,基于多个底栖生物指数的主要特点,运用合理的规则确定了底栖生态状况参考条件,并用M-AMBI指数进行了效果评估。分析表明,设定参考条件可以更为准确地评估生态状况,降低错误分类的风险。Macrobenthos can be used as good indicators for marine ecological quality status due to their lifestyle and Environmental stress ability.Recently multiple indices have been used to evaluate the benthic ecological status,because of the conceptual basis for each indices may rely on different assumptions and parameters,they were unable to give a consistent classification.In order to get a better evaluation of the benthic community health of Jiaozhou bay,we examined the changes of benthic communities over the past seven years,analyzed the main advantages and disadvantages of indices,established reasonable rules to selecte reference conditions,at last evaluate the selection effect by M-AMBI.Here we argue that setting reference conditions can reduce the error classification risk,helping us to identify the ecological status of Jiaozhou bay.
