| 中文摘要: |
| 根据厦门海域鱼类种类组成历史资料和调查资料,系统整理了厦门海域的鱼类总名录和现有名录,并应用分类学等级多样性指数和分类差异变异指数分析了厦门海域鱼类群落分类学多样性的时空变化。结果表明:厦门海域有记录鱼类共649种;现有鱼类有331种,隶属2纲22目90科181属,其中软骨鱼纲共5目9科9属15种,辐鳍鱼纲共17目81科172属316种。厦门海域鱼类总名录的等级多样性指数Δ+和分类差异变异指数Λ+分别为79.267和220.96;现有鱼类群落分类多样性指数Δ+和分类差异指数Λ+分别为77.504和245.34。分类多样性指数Δ+在冬、春季较高,秋季次之,而夏季最低;而分类差异指数Λ+夏季较高,秋季次之,冬春季较低。秋季和冬季鱼类组成的相似度最高,其次为夏季,最后为春季。与历史总名录相比,厦门海域的现有鱼类群落分类学范围较小,生态幅变窄,群落稳定性较差。 |

| Based on literature and survey data of fish composition collected by bottom trawl investigation from 2006 to 2007 in Xiamen coastal waters,the fish fauna was set up, fish community and the taxonomic diversity and distinctness by using taxonomic diversity Δ+ and taxonomic distinctness Λ+ were analyzed. The results show that: there were 649 species of fishes recorded in Xiamen coastal waters. 331 species of fishes were available at present,belonging to 2 classes, 22 orders, 90 families and 181 genera, as for the Chondrichthyes fishes were composed of 5 orders, 9 families, 9 genera and 15 species, while the Actinopterygii fishes were composed of 17 orders, 81 families, 172 genera and 316 species. The taxonomic diversity Δ+ and taxonomic distinctness Λ+ of the fish community master list in Xiamen coastal waters were 79.267 and 220.96, 77.504 and 245.34 at present, respectively. The taxonomic diversity Δ+ in winter and spring was higher than summer and autumn, and it was lowest in summer. While the taxonomic distinctness Λ+ was highest in summer and lower in winter and spring. The fish compositions in autumn and winter had the highest similarity, followed by summer, and lowest in spring. Compared with historical data, fish community in Xiamen coastal waters is being smaller in the taxonomic range and narrower in ecological amplitude. The stability of the fish community is potential recession and the ability to resist change is down. |
