| 摘要: |
| 为探究海岸工程对北海铁山港榄根村红树林大型底栖动物群落的影响，本研究于2020年3月对红树林死亡区（D组）、红树林严重退化区（ED组）、活林区（AL组）、对照林区（CK组）等4个区域的大型底栖动物进行定量取样调查。结果显示，4个调查区域大型底栖动物共45种，平均栖息密度和生物量分别为102.4个/m2、147.55 g/m2；Shannon-Wiener多样性指数（H'）、Pielou均匀度指数（J）和Margalef物种丰富度指数（d）分别为2.050，0.735，1.329。单因素方差分析表明，不同区域之间的大型底栖动物栖息密度、生物量、H'、J和d均无显著性差异。但红树林死亡区（D组）和红树林严重退化区（ED组）的大型底栖动物栖息密度、生物量、H'均低于对照林区（CK组）和活林区（AL组），表明D组和ED组的大型底栖动物群落在海岸工程的影响下受到了更严重的干扰。聚类分析和多维尺度排序（MDS）分析表明，D组与ED组的大型底栖动物群落较为相似，而AL组的大型底栖动物群落则与CK组相似。以上结果表明，海岸工程导致北海铁山港榄根村红树林生态系统受损及其底质环境发生改变，并对该区红树林的大型底栖动物栖息密度、生物量、多样性指数、优势种和群落结构造成了一定负面影响。 |

| Abstract: |
| In order to study the impact of the coastal engineering on macro-benthic communities in the mangrove of Lan'gen Village in Tieshan Bay, Beihai, in this study, quantitative sampling survey was conducted on macro-benthos in four areas in March 2020, including dead mangrove area (group D), severely degraded mangrove area (group ED), living mangrove area (group AL) and control mangrove area (group CK). The results showed that there were 45 species of macro-benthos in the four survey areas, and the average habitat density and biomass were 102.4 ind. /m2 and 147.55 g/m2, respectively. The Shannon-Wiener diversity index (H'), Pielou evenness index (J) and Margalef species richness index (d) was 2.050, 0.735, and 1.329, respectively. Single factor analysis of variance showed that there were no significant differences in macro-benthic habitat density, biomass, Shannon-Wiener diversity index (H'), Pielou evenness index (J) and Margalef species richness index (d) between different areas. However, the habitat density, biomass and H' of macro-benthos in dead mangrove area (group D) and severely degraded mangrove area (group ED) were lower than those in control mangrove area (group CK) and the living mangrove area (group AL), which indicated that the macro-benthic communities in group D and group ED were more seriously disturbed under the impact of coastal engineering. Cluster analysis and multidimensional scaling (MDS) analysis showed that the macro-benthic communities in group D and ED were more similar, while those in group AL had a higher level of similarity to those in group CK. The above results showed that the coastal engineering had caused damage to the mangrove ecosystem and changed the sediment environment in the mangrove of Lan'gan Village, Tieshan Bay, Beihai. And it also had a certain negative impact on the macro-benthic habitat density, biomass, diversity index, dominant species and community structure in mangrove. |
