| 摘要: |
| [目的]对厦门湾的底栖动物群落健康状况进行调查分析,初步构建合适的评价方法,并据此判断厦门湾的底栖生态质量状况。[方法]以2011年3月、6月调查数据为基础,采用Shannon-Wiener生物多样性指数、Margalef丰富度指数以及M-AMBI (Multivariate-AZTI's Marine Biotic Index)作为构建大型底栖动物群落指数(macrozoobenthos community index,MCI)的指标,在等权重加和的基础上获得MCI值。[结果]3月份厦门湾大型底栖动物群落质量差于6月份,且以同安湾的质量最差,东部和西部海域的则最好;九龙江口河口区的群落质量状况呈现明显的空间梯度,沿河口向外、向北部逐渐变好。[结论]厦门湾底栖动物群落之间的时空差异与多种环境因素的联合作用有关,而MCI能够较为敏感地响应这种时空变化,适用于评价厦门湾大型底栖动物群落质量状况。 |

| Abstract: |
| [Objective] The benthic animal community health in Xiamen bay was investigated, and a suitable evaluation method was preliminarily built, by which the quality condition of benthic ecology in Xiamen bay was estimated.[Methods] Based on the materials collected from Xiamen Bay in March and June 2011, the Shannon-Weiner diversity index, Margalef richness index and M-AMBI were selected to set macrozoobenthos community index (MCI) to assess the macrozoobenthos community health status.Furthermore, each index was given a suitable score and weighted average to count the MCI value.[Results] The macrozoobenthos community health in March was worse than that in June in Xiamen Bay.And, Tong'an Bay was presented as the worst health of macrozoobenthos community, while the eastern and western areas were presented as the best in our studied areas of Xiamen Bay.A clear spatial gradient of changing community quality was found along the Jiulongjiang estuary to off shore and northern-wards areas, indicating that the quality status became gradually better off estuary and forward northern part.[Conclusion] The characters of spatial and temporal distribution patterns of macrobenthic assemblages in Xiamen Bay were closely related to the combined effects of several environmental factors.It is demonstrated here that the MCI could be used to assess the health status of macobenthic assemblages in Xiamen Bay. |
