| 摘要: |
| 区系是海藻生物地理研究的基本单位，是以一定时间、空间范围内的全部海藻为对象划分的生物地理单元，具有相对稳定的温度性质、物种组成和边界范围，且区系之间具有较明显的差异。然而，长期以来海藻的区系研究仅以定生的底栖海藻为研究对象，对于漂浮海藻则没有明确的定位。近年来世界各地漂浮海藻造成的藻华频发，在一些海域漂浮海藻已成为周期性存在，同时分子技术的发展为海藻生物地理学研究提供了有力的支撑，为追溯、比较漂浮海藻及其与定生海藻的关系提供了可靠的参考。漂浮海藻对于认识全球变化和人类活动对海藻分布、适应与进化的影响具有重要研究意义。本文结合漂浮海藻的特点和海藻生物地理学的基本研究方法探讨漂浮海藻与海藻区系的关系。 |

| Abstract: |
| Seaweed flora was a sum of all the seaweed populations within definite time and space, with stable temperature, species composition and boundaries. There were two main types of seaweeds which were attached seaweeds and floating seaweeds. In flora study only the attached seaweeds were included, while there was no clear definition of floating seaweeds. Recent years the blooms of floating seaweeds had been a periodical phenomenon within some area in the world, which made it necessary to analyze the relationship between floating seaweed and seaweed flora. With the support from the molecular technology, it was available to carry out tracing and comparative research between attached and floating seaweeds. This paper discussed the relationship between floating seaweeds and seaweed flora. The two main results were: it was still hard to definite floating seaweed as a flora unit; meanwhile, floating seaweed could be a potential connection among different floras. |
