| 摘要: |
| 于2007年10月至11月2008年4月至5月采用样条调查法调查广西涠洲岛造礁石珊瑚的属种组成及其分布特征。结果调查得到涠洲岛共有石珊瑚10科22属46种以及9个未定种,西南部、东北部沿岸海域属种较多,有8科13属,珊瑚种群的生物多样性程度较高。涠洲岛活石珊瑚的平均覆盖度以西北部沿岸、东北部沿岸海域较高,东南部、北部、西南部次之,分别为25.3%、24.58%、17.58%、12.1%、8.45%。涠州岛的西南面和东南面沿岸海域长年受到船舶停靠和输运、过度捕捞、大规模挖礁、岸上及海上养殖等人为干扰胁迫,石珊瑚覆盖相对较低。 |

| Abstract: |
| Adopting transect line method, we surveyed Species composition and distribution of coral on Weizhou Island Beihai in Oct.2007, Nov.2007 and Apr.2008, May.2008.The results showed that the coral species on Weizhou Island comprises 46 recognizable and 9 uncertain species, belonged to 22 genera in 10 families;and much more abundance in genera and species was found on the southwestern and northeastern coastal waters areas with 13 genera, 8 families both.There was a higher biodiversity of coral at the south-west and north-east coast.Higher living coral coverage appears on the northwestern and northeastern coast, and the next on the southeastern, northern, and southwestern coast, with an average percentages of 25.3%, 24.58%, 17.58%, 12.1% and 8.45%, correspondingly and respectively.Relatively low living coral coverage on the southwestern and southeastern coast suggested that it may result from disturbing and threatening factors created by all-the-year-round frequent boats' anchoring and passing-by, over fishing into the reef, large-scale coral reef collecting, on-shore and on-the-sea fish farming, and the like. |
