The ability of the two synthetic marine biotic indices, AMBI and M-AMBI, to account for changes in the ecological quality of coastal soft bottoms of Reunion Island according to disturbances was assessed from macrobenthic samples collected in five sectors between 1994 and 2004. Samples were collected under non-perturbed conditions and at two sites subjected to heavy organic enrichment. Both indices are based on a classification of macrofauna into ecological groups (EG), and their transfer to tropical waters required some adaptations. These indices proved efficient in detecting a degradation of habitat quality. Their use resulted in the classification of all sites sampled between 1996 and 1998 as "good" or "high". M-AMBI nevertheless tended to result in the attribution of a slightly worse ecological quality status than AMBI. Together with an update of the EG species list for the Indian Ocean area, our results support the extension of both indices for the assessment of tropical soft bottoms.
根据1994年至2004年间在留尼汪岛五个区域采集的大型底栖动物样本，评估了两种综合海洋生物指数AMBI和M - AMBI根据干扰情况反映留尼汪岛沿海软底生态质量变化的能力。样本在未受干扰的条件下以及在两个遭受严重有机富集的地点采集。这两种指数均基于将大型动物分类为生态组（EG），并且将它们应用于热带水域需要进行一些调整。这些指数被证明在检测栖息地质量退化方面是有效的。它们的使用使得1996年至1998年间采样的所有地点被分类为“良好”或“高”。然而，M - AMBI倾向于得出比AMBI略差的生态质量状况。连同印度洋区域EG物种列表的更新，我们的结果支持将这两种指数扩展用于评估热带软底。
