| Abstract: |
| The protection of the biological diversity and the maintenance of the regional ecological integrity for the Huanghe (Yellow River) Estuary and its adjacent areas are practically significant and valuable. However, frequent human activities and natural climate changes have caused vigorous disturbances on the ecosystem in these sea areas. An objective assessment on the benthic habitat quality (BHQ) of the Huanghe Estuary and its adjacent areas is conducted, using AZTI's Marine Biotic Index (AMBI) and multivariate AMBI (M-AMBI) based on the data of macrobenthos in May and August 2011. The results show that both the indices do not correlate significantly, and their assessment results are greatly different. All of the samples assessed using the AMBI were "high" or "good", because the ecological group I (EGI) and the ecological group II (EGII) were dominant macrobenthic ecological groups in the research area. Owing to a low species' richness and a high individual abundance in some samples, the BHQ levels using the M-AMBI were worse than those of the AMBI. Significant correlations are observed between the M-AMBI, water depth, bottom water salinity and dissolved inorganic nitrogen, thus the M-AMBI could sensitively respond to environmental changes and distinguish influences from uninfluenced stations, but the AMBI could not. The consistent results between the AMBI and the M-AMBI mainly appeared in the uninfluenced (undisturbed or slightly disturbed) stations. Therefore, the M-AMBI is more effective than the AMBI in assessing the benthic habitat quality in the Huanghe Estuary and its adjacent areas. Using the M-AMBI to assess the BHQ of the Huanghe Estuary and its adjacent areas, the results show that 3% of the stations are undisturbed and the BHQs are "high", and 61% of the stations are slightly disturbed and those of the BHQ are "good", and the rest are meanly disturbed and those of the BHQ are "moderate". |

| 黄河口及邻近海域在生物多样性保护和维护区域生态功能完整性方面具有重要的意义与价值，但受人类活动和气候变化的影响该区域环境已经受到剧烈扰动。本研究的目的是在2011年5月份和8月份大型底栖动物的数据基础上，应用AMBI和M-AMBI指数对黄河口及邻近海域底栖生境质量进行客观评价。结果显示，两指数之间无显著相关性，它们的评价结果差异较大。其主要原因是研究区大型底栖动物以生态群落EGI和EGII物种为主，AMBI评价所有的样品均为高等和良好，而样品中存在物种数较低和单一物种丰度占较大优势的情况，M-AMBI指数评价的底栖生境质量等级远差于AMBI指数评价的等级。M-AMBI指数对黄河口及邻近海域的环境压力更敏感，与水深、盐度、溶解无机氮均呈显著相关关系，而AMBI对这些环境参数则是不敏感的。M-AMBI指数在区分受影响和未受影响的站位是有效的，而AMBI则不能。利用M-AMBI指数评价显示黄河口及邻近海域2011年5月和8月底栖生境3%站位未受扰动，底栖生境质量为高等，61%的站位受到轻度扰动，底栖生境质量为良好，36%的站位受到中度扰动，底栖生境质量为中等。 |
