| 摘要: |
| 三沙市地处南海, 除广阔的海域外, 还有众多的岛屿(礁), 自然资源丰富。西沙群岛、南沙群岛和中沙群岛等组成了我国三沙市南海诸岛。根据多年来我国科研人员在该海区的调查研究, 作者对我国三沙市南海诸岛海区的海藻区系进行初步的植物地理学研究, 以探讨该海域海藻区系的温度性质及其与其它相关海区海藻区系的关系。研究结果表明, 我国三沙市南海诸岛底栖海藻区系与北太平洋西部海藻相同种数最多的是区系性质为热带性的南海南区, 因此海藻区系的温度性质具有很明显的热带性。另外, 三沙市南海诸岛海藻区系与印度洋海藻区系有很多共同成分, 两地共有种数高达184种, 为南海诸岛海藻总数的63%, 进一步证明我国三沙市南海诸岛区系属于暖水性印度—西太平洋区, 印—马亚区。研究结果对系统调查分析我国三沙市底栖海藻资源进而开发利用南海资源有重要的意义。 |

| Abstract: |
| Sansha City was newly established on July 24, 2012 and administers the Xisha, Zhongsha, and Nansha islands and atolls in South China Sea. The city occupies a wide marine area, and is very rich in natural resources and diversified in biological species. Over the years, Chinese scientists have conducted many investigations in the region. With the records we collected, we summarized the materials and systematically analyze the flora focused on the phytogeography to determine the habitat characteristics and the relationships to the neighboring algal floras. Our findings demonstrate that the most species in Sansha area are in common with the western North Pacific ones, and are characteristic of the tropical type in the southern South China Sea. In addition, the algal flora has many species (184, accounting for 63%) in common with those of the Indian Ocean. Therefore, the algal flora in Sansha City area belongs to the Indo-Malayan subregion of the tropical Indo-western Pacific region, which is important to explore and use the algal flora resources in the study area. |
