| 摘要: |
| 为了厘清防城港白龙半岛海域造礁石珊瑚群落分布特征，本研究采用点样线法（Point Intercept Transect，PIT）和样方法于2020年10月对防城港白龙半岛海域造礁石珊瑚群落进行研究。结果表明，该海域造礁石珊瑚群落分布区面积62.1 hm2，根据珊瑚分布的位置，可将其划分3个分布区，其中分布区二面积最大，为54.8 hm2，分布区一和三的面积则分别为2.8，4.5 hm2。鉴定出白龙半岛共有造礁石珊瑚5科8属12种，其中斯氏伯孔珊瑚（Bernardpora stutchburyi）和多孔同星珊瑚（Plesiastrea versipora）为区域优势种；造礁石珊瑚形态主要为表覆状和块状，活珊瑚平均覆盖度为6.6%，平均珊瑚密度为2.12 ind./m2，平均个体大小为170.14 cm2。珊瑚白化率相对较低，平均为0.43%。防城港白龙半岛海域造礁石珊瑚分布面积小，群落种类单一，覆盖度相对较低，尚不成礁。 |

| Abstract: |
| In order to clarify the distribution characteristics of reef-building coral communities in Bailong Peninsula, Fangchenggang, in this study the Point Intercept Transect (PIT) and quadrat method were used to study the reef-building coral communities in Bailong Peninsula, Fangchenggang in October 2020. The results showed that the distribution area of reef-building coral community was 62.1 hm2. According to the location of corals, it can be divided into three distribution areas, of which the distribution area Ⅱ was the largest, which was 54.8 hm2, and distribution area Ⅰ and Ⅲ were 2.8 and 4.5 hm2, respectively. Through identification, there were 5 families, 8 genera and 12 species of reef corals in Bailong Peninsula. Among them, Bernardpora stutchburyi and Plesiastrea versipora were the regional dominant species. The morphology of reef-building corals was mainly encrusting and massive. The average coverage of live corals was 6.6%, the average coral density was 2.12 ind. /m2, and the average individual size was 170.14 cm2. The coral bleaching rate was relatively low, with an average of 0.43%. The distribution area of reef-building corals in Bailong Peninsula of Fangchenggang is small, the community type is single, and the coverage is relatively low, and forming coral communities rather than reefs. |
